Mass Timber, Passive House, & a Curving Roof: This Canadian Community Centre Is the Civic Building Other Cities Should Be Copying

There’s a version of a public building that checks all the sustainability boxes and still feels cold, institutional, and somehow indifferent to the people it’s meant to serve. The new Marpole Community Centre is not that building. Designed by Diamond Schmitt for the City of Vancouver and the Vancouver Board of Parks and Recreation, it’s nearing completion in Oak Park. It quietly resets expectations for what a civic facility can be.

The project replaces a well-loved but outgrown facility with a two-storey structure nearly double its size, measuring 5,000 square metres. The program is generous: a gymnasium, fitness centre, field house, multi-purpose rooms for seniors and youth, and a 74-space childcare facility. Underground parking is tucked beneath the building to protect the surrounding natural vegetation, letting Oak Park remain exactly that — a park.

Design: Diamond Schmitt

What makes the architecture worth paying attention to is the mass timber. Rather than limiting wood to the roof structure, as institutional buildings often do, the Marpole Community Centre uses a comprehensive mass timber frame — glulam columns and beams, a CLT floor system, and a long-span upper roof built from steel wide flange beams and a CLT deck. The result is a structure that reads as warm and considered, not engineered into submission. Exposed throughout the interior, the timber gives the building a human scale that concrete rarely allows.

The signature move is the gently curving roof. The doubly curved cantilever form, supported by long-span steel beams, required close coordination between the design team and contractors — but the payoff is an exterior that feels unified without being monotonous, and an interior where the ceiling becomes the experience. Strategic glazing pulls the landscape in, connecting occupants to Oak Park’s natural setting without sacrificing energy performance.

On the sustainability front, the numbers are serious. The building targets Passive House and LEED Gold certifications and has achieved a 41% reduction in embodied carbon. It’s also a pilot project for the City of Vancouver’s Embodied Carbon Guidelines, meaning lessons learned here will directly shape future civic buildings across the city. The project is also pursuing the CAGBC’s Zero Carbon Building Design Standard.

Beyond the technical performance, the centre was designed with inclusion, equity, and Indigenous cultural representation as core principles — not afterthoughts bolted on at the end. For a neighbourhood as diverse as Marpole, that intentionality matters. A community centre tends to be the most democratic building a city can build. This one makes a strong case that it can also be among its most thoughtful.

New 2 World Trade Center Will Rise 1,226 Feet Over Manhattan, Finally Completing the Post-9/11 Rebuild

It has been almost 25 years since the September 11 attacks forever changed the skyline of Lower Manhattan, and now the rebuilding of the World Trade Center campus is entering its final stretch. The last major commercial tower on the site, 2 World Trade Center, is expected to break ground in spring 2026 and wrap up construction by 2031. American Express has committed to making the building its new corporate headquarters.

Getting to this point hasn’t been simple. British firm Foster + Partners was originally hired to design the tower, only to be replaced by Bjarke Ingels Group, which put forward a striking terraced concept. That plan was eventually scrapped, and Foster + Partners was brought back to start fresh. The result, based on recently released renderings, is a broad rectangular tower sheathed in glass, with three open-air terraces and six landscaped corner gardens woven into the facade to bring some greenery to an otherwise sleek profile.

Designer: Foster + Partners

The tower will rise to 1,226 feet, comfortably placing it in the supertall category and making it roughly the 11th-tallest building in the United States. It won’t overtake its famous neighbor, though. One World Trade Center still holds the title of the country’s tallest at a symbolically chosen 1,776 feet. Inside, the building will offer close to two million square feet of usable space across 55 stories, with the bulk of that dedicated to offices. When fully occupied, it could house around 10,000 workers.

Specifics are still thin at this early stage, but American Express has said the tower will incorporate smart building technology and energy-efficient systems. The project is also targeting LEED certification, which has become something of a baseline expectation for major commercial developments in recent years.

Kevin O’Toole, Chairman of the Port Authority of New York and New Jersey, called the project a meaningful milestone, both for the campus and for the surrounding region. He pointed to the tower’s role in reinforcing the World Trade Center as one of the country’s most important centers of commerce and transportation, and acknowledged just how much sustained effort it takes to deliver projects on this scale.

Silverstein Properties, the development firm that has overseen much of the site’s post 9/11 transformation, is once again at the helm. When the building finally opens its doors in 2031, it will effectively close the book on one of the most ambitious and emotionally significant urban rebuilding efforts in modern history. More than anything, it will stand as a reminder of what New York City is capable of when it commits to moving forward.

ZHA’s Dramatic Canyon-Cut Tower Tops Out In Shenzhen’s Cultural District

The latest Zaha Hadid Architects project to rise in Shenzhen looks like it belongs in another world entirely. The Yidan Center, which just topped out this month, cuts a dramatic figure against the city skyline with its rippled, canyon-like form that seems to defy conventional building logic.

This isn’t just another flashy tower, though. The 165,815-square-meter complex will serve as headquarters for the Yidan Prize and the Chen Yidan Foundation, both the brainchild of Tencent co-founder Dr. Charles Chen Yidan. The building sits at the heart of Shenzhen’s emerging cultural district, right next to the new Qianhai Museum, positioning itself as a serious player in the city’s cultural landscape.

Designer: Zaha Hadid Architects

Nature Meets Architecture

What makes this building truly striking is the massive outdoor void carved right through its center. ZHA calls it a “canyon,” and the comparison isn’t hyperbole. The architects drew inspiration from the natural valleys and gorges that crisscross the region, creating a central space that feels both dramatic and purposeful. Terraces and balconies wrap around this central void, turning what could have been a simple courtyard into something far more dynamic.

The idea is to get people moving between levels, encouraging the kind of spontaneous encounters that spark collaboration. It’s a bold move that transforms circulation into an architectural event. The building’s skin tells its own story through layers of external louvers that create deep shadows and changing patterns throughout the day. These aren’t just for show – they block harsh sunlight while preserving views out to Qianhai Bay, a practical solution wrapped in compelling form.

Green Ambitions

For all its sculptural drama, the Yidan Center takes sustainability seriously. The project targets China’s top-tier three-star green building certification plus LEED Gold, no small feat for a building this complex. The design incorporates hybrid ventilation systems and smart glazing to handle Shenzhen’s notoriously humid climate without relying entirely on mechanical systems. Principal Patrik Schumacher and Project Director Manuela Gatto led a team that had to balance the building’s artistic ambitions with its practical requirements.

The result feels both otherworldly and grounded in real-world constraints. The building’s mission centers on education and innovation, housing research facilities and exhibition spaces that will support the foundation’s work in educational reform. Visitors will enter through landscaped gardens that slope down to the canyon floor, where a large skylight floods the interior with natural light. The lower levels will house YiPai, a community-focused learning initiative designed to welcome people of all ages. It’s an ambitious social program that uses architecture as a catalyst for broader educational goals.
