The Hive Tower That Could Change How Cities Build Tall

Posted on by

Vancouver just opened a building that looks like it was sketched from a bee’s imagination. Ten stories of glulam diagonal bracing arranged in a cellular honeycomb pattern, climbing above the False Creek Flats neighborhood at 2150 Keith Drive. No concrete core. No steel skeleton hiding inside. Just engineered wood, a very smart structural idea, and 106 seismic dampers quietly doing something extraordinary.

The Hive, designed by Dialog in collaboration with structural engineers Fast+Epp, is officially the tallest seismic-force-resisting mass timber building in North America. Nature’s Path Foods was an early believer in the project. The Insurance Corporation of British Columbia (ICBC) just signed on as anchor tenant, which matters more than it sounds. When an insurance company chooses to occupy a timber building designed for earthquake territory, it’s a signal about confidence, not just aesthetics.

The structural decision at the center of this building is worth pausing on. Most architects building in seismic zones lean on a concrete core to handle lateral loads, then wrap wood or steel around it. Dialog chose not to do that here. Instead, the glulam diagonal braces run along the building’s perimeter, forming that honeycomb grid that reads immediately as a design statement but is actually the load-bearing logic made visible. The structure isn’t decorating the facade. The facade is the structure.

Paired with those diagonal glulam braces are 106 Tectonus damper connections, a system borrowed conceptually from how tectonic plates behave during seismic events. Rather than resisting an earthquake by brute force, the building is designed to move with it, absorbing energy through the dampers and then self-centering once the shaking stops. Testing was carried out at the University of Alberta using large physical mockups to prove the system would hold. That kind of pre-construction stress testing is not a given, and it reflects the level of scrutiny this project had to pass to exist at all.

The reason that scrutiny was so high comes down to code. Canada updated its National Building Code in 2020 to permit mass timber buildings up to 12 stories, with changes taking effect in 2022. Vancouver sits in a high-seismic zone, which added requirements beyond the base code. Getting a tall timber building approved here required not just meeting those new standards but helping to write the engineering case for them. The team received $4 million in research funding from federal and provincial governments to do exactly that, covering destructive testing, fire testing, and constructability analysis. The Hive didn’t just benefit from the regulatory shift. It helped earn it.

The comparison to other celebrated mass timber towers is instructive. Milwaukee’s Ascent is remarkable at 25 stories, and buildings like Neutral Edison have made compelling arguments for timber in dense urban settings. But neither sits in a high-seismic zone. The Hive isn’t the tallest timber building; it’s the most structurally tested in the conditions most buildings actually fear. Seismic credibility is the specific gap it fills, and filling it in a major North American city with a government-insurer anchor tenant is a different kind of proof than any design award.

The honeycomb wasn’t chosen to be pretty. It was chosen because the diagonal brace geometry at the perimeter is the most efficient seismic solution for a building this size without a concrete core. And yet the result is one of the most graphically immediate buildings to open anywhere this year. When the structural diagram and the brand identity are the same thing, something has gone right at a foundational level in the design process.

Mass timber has been in a years-long tug-of-war between its admirers and its skeptics. The admirers point to carbon storage, warmth, biophilic benefits. The skeptics point to fire risk, insurance costs, and seismic uncertainty. The Hive answers the hardest skeptic argument directly, in one of the most seismically demanding cities in Canada. Whether it fully tips the debate probably depends on what gets permitted and built next. But as an opening move, it’s a strong one.

Africa’s Tallest Tower Was Worth the 40-Year Wait

Posted on by

Forty years is a long time to wait for a building. But when you see what’s rising in Abidjan, the delay starts to feel almost intentional — like the city was simply holding its breath for the right moment. Tour F, the supertall skyscraper currently piercing the skyline of Ivory Coast’s economic capital, was first imagined in the 1970s as part of a sweeping urban development plan for Abidjan’s Plateau district. The idea was straightforward: complement the existing administrative towers — A through E — with a sixth.

What wasn’t straightforward was actually building it. The project stalled for decades, a vision suspended in bureaucratic and economic uncertainty. Construction finally broke ground in 2021, with BESIX Group drilling 70 foundation bars and 62-meter-deep diaphragm wall panels to anchor the structure.

Designer: Pierre Fakhoury

Designed by Lebanese-Ivorian architect Pierre Fakhoury — the same mind behind the breathtaking Notre-Dame de la Paix Basilica in Yamoussoukro — Tower F is not trying to be a generic glass box. It has something to say. The form is sculptural: a slender volume whose facade is carved into trapezoidal inclined glass planes, each facet tilting inward toward the earth or reaching toward the sky. The top is cleanly truncated, then crowned with a dramatic extension of the glass facade that dissolves into open air. It’s restrained and bold at the same time — a difficult balance that Fakhoury pulls off with architectural confidence.

What makes the design genuinely compelling is its embedded cultural logic. When viewed from a certain angle, the play of facets reads as a stylized African mask — a nod to West African artistic tradition embedded quietly into a 21st-century supertall. The building is symmetrical along its east-west axis, grounding the sculptural gesture in structural clarity. At street level, a simple rectangular podium houses the main entrance hall and support services, keeping the base honest and approachable despite the tower’s imposing scale.

At 421 meters, Tower F is set to claim the title of Africa’s tallest building, surpassing The Leonardo in Johannesburg. The gross floor area reaches approximately 140,000 square meters, consolidating government ministries and administrative units currently scattered across the city — a practical ambition wrapped in an extraordinary shell.

Construction costs are estimated at approximately €450 million, developed through a collaboration between the Ivorian Ministry of Construction and local firm PFO Africa. Completion is expected in 2026. For a continent whose architectural ambitions are accelerating fast, Tower F is exactly the kind of project that reframes the conversation — not just about African skylines, but about what it means to design a building that carries cultural memory into the future.

TRÆ Is the Timber Tower That Turns Waste Into Architecture

Posted on by

There’s a word in Danish, ‘træ’, that means three things at once: tree, timber, and three. It’s a fitting name for a building that refuses to be just one thing. Designed by Lendager and completed in Aarhus’ former industrial South Harbour, TRÆ stands 78 meters tall across three interconnected volumes, earning its place as Denmark’s tallest timber tower and the world’s first upcycle timber tower.

The ambition behind it is disarmingly simple: prove that a tower can be built from waste and wood without sacrificing safety, economy, or quality. What makes TRÆ remarkable isn’t just the height, it’s the conviction. The building operates within two material ecosystems simultaneously: the biogenic and the circular. Mass timber columns, cross bracing, and CLT floor slabs form the primary structure, with low-carbon concrete used only in the cores for fire safety and stability. Everything else is drawn from what already exists.

Designer: Lendager

The façades are the project’s most striking argument. Salvaged aluminium sheets, arranged to evoke the texture of birch bark, mottled, imperfect, alive, clad the exterior in industrial leftovers that feel entirely intentional. Retired wind turbine blades, repurposed as solar shading, line the building’s south-facing elevations. A comparative analysis showed their estimated carbon footprint to be 27 times lower than conventional aluminium solar screens. The math is compelling. The aesthetic is better.

Measured against a conventional concrete benchmark, TRÆ achieved a 26 percent reduction in CO₂ emissions, 21 percent from the timber-led design and 5 percent from integrated reused materials. It’s a number that reshapes the conversation around tower construction, a typology long associated with emissions-heavy concrete and steel. The project doesn’t chase certification checklists. Instead, it follows a value-driven framework that prioritises measurable outcomes from the ground up.

The social dimension is just as deliberate. TRÆ houses a volunteer initiative providing daily meals to families in need, and involves homeless people in the building’s upkeep, folding existing social realities directly into the life of the building. An undulating pedestrian bridge, starting at street level, snakes upward to connect TRÆ to Aarhus’ new highline, threading the tower into the city rather than above it.

The Aarhus Architecture Awards jury awarded TRÆ Best Building in 2025, noting that it “does not necessarily adhere to a classic architectural or beauty ideal” but stands as “an energetic reckoning with well-tested solutions and zero-error culture.” That’s exactly the point. TRÆ isn’t trying to be perfect. It’s trying to be right.

Four Meters by Four Meters: How Tadao Ando Made Constraint Beautiful

Posted on by

Perched on the coast of the Seto Inland Sea in Tarumi-ku, Kobe, the 4×4 House by Tadao Ando occupies a narrow coastal strip that Japanese authorities had not even considered constructible. That is exactly why Ando built there. Completed in 2003, the house rose in the shadow of the Great Hanshin earthquake, a catastrophe that reshaped the region and the consciousness of everyone who lived through it. Ando’s response was not to build bigger or safer in the conventional sense.

It was to build with precision — a four-story reinforced concrete tower with a footprint of just four meters by four meters. Sixteen square meters of floor area, multiplied upward toward the sky. The name is the blueprint.

Designer: Tadao Ando

At 13.4 meters tall, the structure reads less like a residence and more like a sentinel. Its silhouette evokes a watchtower — upright, deliberate, scanning the horizon. Ando sank the foundations deep into the ground to resist lateral forces, and at the base, a square concrete patio disappears beneath the waterline when the tide comes in. The boundary between architecture and ocean is intentionally blurred. Living here means accepting the sea as a roommate.

The interior climbs through a vertical sequence of rooms, each floor stacked with the discipline of a column. What makes the composition unusual is the top floor — a cube shifted slightly off-axis from the floors below, a geometric move that feels almost offhand but transforms the entire silhouette. Light enters in controlled bursts. Views are framed like paintings. Nothing is accidental.

Not long after the first house was finished, a second client commissioned Ando to build an identical tower on the neighboring plot. The result is a pair of concrete twins standing side by side on the coastline, same in form but different in material — a duality Ando had quietly envisioned from the beginning. The two buildings share no physical connection. They stand together, facing the sea, as if in silent conversation.

The 4×4 House is not a comfortable building in the traditional sense. It is a provocation — a proof that constraint, when embraced fully, becomes its own kind of freedom. Ando took a strip of coastline that the city had written off and turned it into one of the most discussed residential structures of the 21st century. Sixteen square meters at a time.

UNStudio’s Wasl Tower Is Dubai’s Most Sculptural Skyscraper Yet

Posted on by

There’s a building rising on Sheikh Zayed Road that isn’t trying to be the tallest thing in the room — it’s trying to be the most alive. The Wasl Tower, designed by UNStudio in collaboration with structural engineers Werner Sobek, stands 302 metres above Dubai and carries with it one of the most thoughtful design narratives in the city’s recent skyline story. Conceived as early as 2014 and nearing completion, the 64-storey supertall is a landmark in the truest sense, not just because of its height, but because of what it means to stand there.

The tower draws its form from classical sculpture. UNStudio looked to the ‘contrapposto’, a Renaissance-era pose in which a figure shifts weight and twists slightly at the torso, suggesting movement mid-stride, and scaled it to 302 metres. The result is a building that appears to rotate as you move around it, its geometry shifting with every vantage point. Structurally, this feat is achieved through three massive 300-metre shear walls linked by four strategic outriggers, a system that allows the building to twist gracefully while still supporting a fully flexible, mixed-use floorplate.

Designer: UN Studio

Positioned directly opposite the Burj Khalifa along Dubai’s main north-south artery, the Wasl Tower occupies a site that was previously untouched by high-rise development. A new pedestrian bridge now connects it to the Burj Khalifa metro station, threading the tower into the city’s movement infrastructure and making it a genuine civic node rather than an isolated object. Its programming reflects that ambition — the building houses residential apartments, offices, a hotel, restaurants, and entertainment spaces, with public programming deliberately elevated high above street level.

What gives the tower its visual texture is its facade, one of the tallest ceramic facades in the world. UNStudio and Werner Sobek clad the building in a lace-like grid of glazed clay fins, a material choice that is as low-tech as it is clever. The ceramic tiles diffuse and reflect the desert sun, reducing heat gain and eliminating the need for more energy-intensive shading systems. At night, the facade takes on an entirely different quality, illuminated in a way that makes the building appear to breathe.

For a city that has never been shy about spectacle, the Wasl Tower earns its place on the skyline by being something rarer: a building with a rigorous idea behind it. It references art history, responds to climate, and reshapes a stretch of one of the world’s most iconic roads, all at once.

Morocco’s Mohammed VI Tower: The Rocket That Rewrote Africa’s Skyline

Posted on by

There are buildings, and then there are statements. The Mohammed VI Tower, inaugurated on April 23, 2026, in Salé, Morocco, belongs firmly in the second category. Rising 250 metres across 55 floors on the east bank of the Bouregreg River, it is now the tallest building in Morocco and the third tallest on the African continent. It did not arrive quietly. Visible from 50 kilometres in every direction, the tower has already redrawn the skyline that was once defined by centuries-old minarets.

The story behind it is as cinematic as the structure itself. Othman Benjelloun, the 93-year-old billionaire and chief executive of the Bank of Africa, conceived the idea decades ago after visiting a NASA facility ahead of the Apollo 12 mission. Standing before the Saturn V rocket, he saw not just a machine but a metaphor. That image, a rocket braced on its launchpad and ready to ascend, became the architectural soul of the tower. Spanish architect Rafael de la Hoz and Moroccan architect Hakim Benjelloun translated that vision into steel, glass, and concrete, producing a silhouette that reads like liftoff frozen in time.

Designer: Rafael de la Hoz and Hakim Benjelloun

The tower is far more than its form. Across its 102,800 square metres of floor area, it houses a Waldorf Astoria hotel, premium offices, high-end residential apartments, retail spaces, and a panoramic observation deck at its crown. Interior design was handled by Pierre Yves Rochon, with furniture and fittings curated by FLAMANT. The facade spans 70,000 square metres and integrates solar panels, while a tuned mass damper ensures stability at height. The building holds both LEED Gold and HQE sustainability certifications, setting a benchmark for green construction across the continent.

Construction began in July 2017 and was delivered by BESIX in a joint venture with TGCC, Six Construct, and the China Railway Construction Corporation, with a total cost of 3.5 billion Moroccan dirhams, roughly $700 million. The project forms the centrepiece of the Bouregreg Valley Development, a broader effort to transform Rabat into a city of international standing ahead of the 2030 FIFA World Cup, which Morocco will co-host.

Not everyone is celebrating at the same altitude. Critics point out that major investment continues to concentrate along Morocco’s Atlantic corridor, while inland regions contend with high unemployment and uneven public services. The tower, they argue, is a monument to ambition that has yet to translate into equity.

Still, as an act of architecture, the Mohammed VI Tower is difficult to argue with. Rafael de la Hoz and Hakim Benjelloun have given Morocco something rare: a building with a founding myth, a bold form, and the scale to match both.

The World’s Tallest Timber Skyscraper Is in Sydney, and It Rises 600 Feet Into the Sky

Posted on by

Sydney is on the verge of claiming a significant architectural milestone. Atlassian Central, a 39-floor hybrid timber tower currently nearing completion, is set to become the world’s tallest building of its kind, surpassing the existing record holder by a considerable margin.

Designed by BVN and SHoP Architects as part of a larger development in Sydney, Australia, the tower will top out at 183 m (600 ft). That makes it more than twice the height of Milwaukee’s Ascent, which currently holds the title of world’s tallest hybrid timber skyscraper at 86.6 m (284 ft). According to the Council on Tall Buildings and Urban Habitat (CTBUH), the premier authority on building heights, Atlassian Central will claim the record upon completion, ahead of any proposals not yet approved.

Designer: BVN & SHoP Architects

The structure relies on a hybrid system of concrete, steel, and engineered wood, a combination that sets it apart from purely timber towers like Norway’s Mjøstårnet. The use of concrete and steel allows the building to reach heights that timber alone could not sustain, while glued-laminated timber columns and cross-laminated timber slabs, sourced from Europe, are incorporated throughout. In total, roughly 10,000 cubic meters (353,000 cubic ft) of engineered wood will be used in the build.

Sustainability is woven into the design beyond the choice of materials. The facade integrates solar panels alongside an automation system developed by specialist EBSA, which is expected to significantly reduce the building’s mechanical cooling requirements. SHoP Architects describe the commercial floors as being organized into seven stacked four-story “habitat” modules, each framed by the hybrid timber structure and designed to maximize natural ventilation, provide access to landscaped terraces, and support workplace well-being through a connection to natural environments.

The tower’s program is varied. The lower floors will house a hostel, and the project will incorporate an existing building on the site, which is being restored and folded into the lobby. The majority of the remaining floors are dedicated to office space, interspersed with multiple open garden areas that reinforce the building’s emphasis on greenery and natural light.

An exact completion date has not been confirmed, but Atlassian Central is expected to be finished in late 2026 or sometime in 2027. When it opens, it will represent not just a new height record for hybrid timber construction, but a meaningful step forward in demonstrating what sustainable high-rise architecture can look like at scale.

Michael Jantzen Just Turned Solar into a 16-Arm Moving Sculpture

Posted on by

Most renewable energy systems hide in plain sight. Rooftop solar panels blend into shingles, batteries sit in containers behind fences, and wind turbines spin in distant fields. They quietly do their jobs without helping anyone understand what happens inside them, which feels like a missed opportunity when you are trying to build support for systems that might keep the planet livable for another generation or two.

Michael Jantzen’s Solar and Gravity Powered Art and Science Pavilion treats that visibility problem as a design challenge. The conceptual structure combines a public exhibition space under an umbrella-shaped roof with a tall central tower supporting 16 long, weighted steel arms. Those arms lift and lower throughout the day, creating shifting silhouettes while demonstrating how solar power and gravity work together as a functional energy system rather than just theoretical concepts.

Designer: Michael Jantzen

The cycle works simply enough. A solar cell array at the top powers 16 winches that pull the weighted arms upward, storing potential energy. When the pavilion needs electricity, or when someone wants to change its shape, the arms fall back down under gravity. Their descent drives 16 generators that feed power to the building or local grid, turning stored height into usable electricity without batteries or other complex systems getting in the way.

Arriving on a sunny afternoon, you would see the arms at different angles around the tower, sometimes clustered vertically, sometimes fanned out like a mechanical flower. The shifting positions are not just decorative but are the visible result of energy being stored and released. You can read the building’s energy state in its skyline without needing a diagram, which turns out to be a surprisingly rare thing for infrastructure to offer at any scale.

Inside, the umbrella roof shelters a large floor for exhibitions, lectures, or performances. At the center, 16 cables drop through holes in the floor, each marked with an orange spot matching the orange-tipped arms outside. Those cables connect to winches and generators below, making the mechanical core part of the exhibition rather than something hidden. Visitors can track which arms are up or down by watching cables move, turning passive observation into something closer to active participation.

Of course, the setup means the building becomes a working model while hosting events about climate or technology. People walk through exhibitions while the structure demonstrates solar capture and gravity storage without needing to explain every detail. The pavilion functions as a tourist attraction, classroom, and public art that teaches through motion instead of asking you to absorb paragraphs about conversion rates nobody remembers afterward.

Jantzen’s proposal might never be built as drawn, but treating energy flows as choreography feels worth exploring. It hints at a future where infrastructure does not just work efficiently behind walls, it performs visibly in ways that invite people to understand systems that usually stay hidden until something breaks. Making those processes watchable might matter more than squeezing out another efficiency percentage point, which is something worth considering the next time we design places meant to teach.

Observation Pavilion Sends a Camera Up While You Stay on the Ground

Posted on by

Climbing an observation tower involves a lot of steel and concrete just to stand a few dozen meters higher and take in a view. The ritual is familiar, the ascent, the vertigo, the panorama, but the infrastructure demands are massive for what amounts to a few minutes of elevated looking. Michael Jantzen’s Telepresence Observation Pavilion asks whether we always need to build big vertical structures to get that feeling, especially when most distant experiences already come through screens and networks.

Instead of lifting people into the air, the pavilion lifts a 360-degree camera on a tall telescoping mast, then brings the view down to ground level. Inside a circular room, a ring of high-definition screens shows a live panoramic feed from the camera, synced with sound, so visitors see and hear exactly what they would if they were standing at the top of a traditional tower, without leaving the ground or climbing a long staircase.

Designer: Michael Jantzen

Walking into a round, open space where the walls behave like windows wraps you in a continuous horizon of forest, water, or city. A circular bench sits around the central mast, the floor stays open, and a guardrail keeps you a step back from the screens, so you are aware you are in a room, but your eyes are convinced you are somewhere higher and more exposed.

The camera sits on top of a tall series of telescoping pipes anchored to the pavilion floor, rising far above the roof. The module captures real-time sights and sounds in every direction, then sends that data down to the screens. The only tower you need to build is this slender mast, not a full structure sized for people, which drastically cuts material and engineering demands.

Eight solar panels ring the central skylight on the pavilion roof, feeding the camera, screens, and lighting. This connects to Jantzen’s goal of using information technology to replace or reduce physical building materials. The pavilion becomes an environmental argument, suggesting that if we can satisfy the desire for elevated views with data and light, we might not need to pour as much concrete into the sky.

Jantzen imagines many camera modules installed on existing structures, communication towers, mountain lodges, and skyscrapers. Those feeds could be sent over the internet to any pavilion, letting visitors switch channels between live elevated views from around the world. You could stand in a field and look out over Tokyo, then switch to a mountain ridge in Patagonia or a coastal city, turning a local building into a global observatory.

This changes the idea of an observation tower. You still make a trip to a specific place and share a room with other people, but the view is no longer tied to that exact spot. It can be curated, rotated, or scheduled, and multiple pavilions can share the same remote vantage point without crowding fragile sites. The architecture becomes as much about routing information as it is about shaping space.

The Telepresence Observation Pavilion will not replace every lookout or mountain hike, and there is still value in feeling the wind and height directly. But as a thought experiment, it points toward a future where we build less mass to get more experience, using cameras, networks, and solar-powered rooms to give people elevated perspectives without the environmental and structural cost of traditional towers, or the bottlenecks that come when everyone wants to see the same sunset from the same narrow platform at once.

Canada’s Tallest Building Takes Shape as SkyTower Reaches Historic 100-Storey Mark

Posted on by

Toronto’s skyline is witnessing a transformation that will redefine Canadian architecture for generations. The Pinnacle SkyTower, designed by Hariri Pontarini Architects, has become the first building in Canada to surpass 100 storeys, marking a pivotal moment in the country’s architectural evolution. When completed in 2026, the supertall will stand at 351.85 metres across 106 floors, claiming the title of Canada’s tallest building.

David Pontarini, founding partner of the Toronto-based firm, envisioned the tower as a direct response to its prominent location at the foot of Yonge Street. The design needed to make a statement worthy of Canada’s longest street while respecting the unique waterfront context. What emerged was a 12-sided crystalline form that catches light from every angle, its glazed surfaces and tapered profile creating a sculptural presence that shifts throughout the day. The geometric complexity serves more than aesthetic ambitions. The dodecahedron shape helps the tower withstand powerful winds sweeping across Lake Ontario, while vertical fins emphasize its soaring height. A distinctive flying buttress connects the tower to its podium base, where horizontal banding creates a visual counterpoint to the vertical thrust above. The podium’s curving form mirrors the natural bend of the lakeshore, anchoring the tower in its surroundings.

Designer: Hariri Pontarini Architects

Engineering a building this tall presented extraordinary challenges. Project architect Nadine El-Gazzar and her team grappled with wind pressure, structural requirements, and the stack effect, which pulls air upward through elevator shafts at tremendous speeds. A custom-designed tuned mass damper will counteract the building’s sway, ensuring comfort for residents on the uppermost floors. These technical solutions remain invisible to observers, allowing the tower’s elegant profile to take center stage.

The mixed-use program reflects contemporary urban living. Over 950 residential units range from intimate 520-square-foot homes to expansive 2,300-square-foot residences. A 220-room Le Méridien hotel occupies the lower twelve floors, while a restaurant on the 106th floor will offer unparalleled views at the same elevation as the CN Tower’s main observation deck. Amenities include a pool, yoga studio, and fitness center, with retail connections to Toronto’s underground pedestrian network at street level.

The project’s ambition grew during development. Originally planned at 95 storeys, a variance request in March 2025 added eleven floors, pushing the design into record-breaking territory. Construction has progressed steadily since groundwork began, with the exterior cladding now substantially complete on the lower sections. The tower rises from the Pinnacle One Yonge development, which transformed the former Toronto Star site into a six-building complex that’s reshaping the city’s waterfront.

Environmental considerations shaped key infrastructure decisions. The development connects to the Enwave Deep Lake Water Cooling system, which draws frigid water from Lake Ontario’s depths for efficient climate control. Pinnacle International president Michael De Cotiis captured the significance: “We have created a landmark, one that is making history not only for Toronto, but for all of Canada.” As SkyTower climbs toward completion, it represents both technical achievement and architectural ambition, a jewel-like form that will anchor Toronto’s skyline for decades to come.
