This cross-laminated timber desert home rates high on sustainability + good looks

Posted on by

Called the Octothorpe House, this impressive home in the Oregon high desert area near Bend was commissioned by a couple Mike and Katherine to Mork-Ulnes Architects. Mike and Katherine decided to move out of their home in San Francisco, to a more outdoorsy rural space, as they felt it would benefit their young son. They wanted a home that would harmoniously merge with the desert landscape, and be environmentally friendly as well. To meet the client’s desire for a sustainable home, Mork-Ulnes Architects decided to use ‘cross-laminated timber’ in the construction of the home.

Designer: Mork-Ulnes Architects

The clients came to us with the idea of building one of the first U.S.-produced cross-laminated timber homes,” said Casper Mork-Ulnes. “They were inspired by the sustainability factor.” Now you may have heard of cross-laminated timber (C LT), it is essentially a wood product built from multiple layers of structural grade lumber that are arranged crosswise, and then glued and attached together. What makes this timber sustainable is the fact that it has a strength-to-weight ratio that’s similar to concrete, but it is five times lighter as compared to it. CLT is pre-cut off site, which also reduces construction waste immensely.

The architects utilized CLT to build the interiors and the exterior of the Octothorpe House, this prevented them from releasing almost 15 metric tons of greenhouse gases into the air. The wooden exterior of the home was treated using the shou sugi ban technique – a Japanese wood burning technique that provides resistance to fire, insects, and decay. The interiors, on the other hand, are inspired by Donald Judd’s Chinati Foundation in Marfa, Texas. The interiors feature concrete floors and dusty pink walls. The home includes two bedrooms and two guest rooms. “One of the guest rooms has a hidden Murphy bed so there is an office for the work-from-home couple,” said Lexie Mork-Ulnes. “The enclosed central courtyard, visible from most of the rooms in the house, doubles as an outdoor playground for their son. In the winter, the large garage space becomes an indoor playroom.”

The home has a really spacious and open feel to it, there’s a sense of liberty and freedom that runs through it, making it an extremely special living space. “The layout offers orchestrated glimpses into the central courtyard and ample views of the sky and desert all around. This creates a delightful connection with the surroundings,” said the architects.

This oddly-shaped Finnish cabin was made with cross-laminated timber to withstand subarctic cold!

This cabin in the woods is an otherworldly, all-black, geometric structure built to provide cozy refuge even in harsh Finnish winters. It was designed for a California-based CEO who returned home to Finland with her family to be closer to her ancestral land so she could maintain it. The cabin is aptly named Meteorite based on its unique shape and is set in a clearing surrounded by spruce and birch trees. The cabin is made entirely from cross-laminated timber (CLT) which is a sustainable alternative to other construction materials.

The three-story home is built entirely from 272 prefabricated panels of cross-laminated, locally sourced timber—a sustainable material that lends itself to digital design methods and follows the Finnish tradition of timber construction. Air gaps of various sizes behind the facade keep the interior warm without conventional insulation, even during Finland’s freezing winters, and give the Meteorite its out-of-this-world shape.

Inspired by the Ice Age rock formations found throughout the region, the Meteorite is a faceted dwelling designed by Kivi and Tuuli Sotamaa, the brother-and-sister duo behind Ateljé Sotamaa. They designed the faceted structure as a guest house for the family, although during the pandemic it has served also as an office for, a recording studio, and an after-school playroom for children.

The Meteorite’s black-tinted exterior provides a stark contrast to the warm, all-wood interior. “Everything on the outside is designed to dramatically stage the inside,” says Kivi. “It’s a mysterious object, and you don’t quite know what is going on within.” Part of the mystique lies in the deceptive nature of its size—the interior spans only 807 square feet of floor space, yet its total volume is 10,594 cubic feet.

Its envelope contains no plastic or insulation; it’s simply two sheets of wood, and the air gap in between them helps to regulate indoor temperature even when the subarctic climate outside drops to single digits in winter. The “between space,” as Ulla describes it, also hides storage and the building’s technical systems, preserving the minimalist feel of the interior.

The Meteorite’s interior is clad in spruce from floor to ceiling, and all the furniture for the living areas were hand-selected works by Finnish designers that the couple picked out themselves. The dining area features a built-in corner sofa designed by Ateljé Sotamaa with slipcovers and pillows by Klaus Haapaniemi & Co – a local artistic brand with works inspired by traditional Finnish folklore.

The Meteorite was originally envisioned as a guesthouse, but with the pandemic keeping them at home, it now serves as a more permanent, multipurpose space for the family. The traditional separation of work and home has disappeared, and it’s beautiful that they are merged within this single building.

My favorite part of the home – and I’m sure also the kids’ – is the giant net on the top floor. It ties the home together visually while adding connectivity without having to be in the same space. It is also extremely well light thanks to the multiple windows and skylights that are placed on unconventional angles because of the unique shape of the cabin.

The warm wooden interior complements the black timber exterior very well. The cabin is a beautiful blend of Finnish and Scandinavian elements in the finer details as well as the overall aesthetic which is minimal and monochromatic. Meteorite is an elegant picture example of modern architecture and interior that has been woven together with local traditions, simplicity, and sustainability.

This prefab tiny home is made sustainably from cross-laminated timber & gives major Japandi vibes!

Posted on by

Prefabricated architecture minimizes construction waste, reduces carbon footprint, and has a quicker turnaround than a traditional home. Minima is a 215-square-foot (20-square-meter) prefab module designed to be a flexible structure to serve as a standalone tiny home or as an additional unit in the backyard that can be used as a home office or spacious guest house. It is constructed with CLT (cross-laminated timber) which is a sustainable material and cuts down on the carbon emissions that concrete produces. The modern micro-home is giving me major Japandi vibes!

The boxy exterior is clad with a skin of cypress battens and a steel roof which maintains its minimal look. The unit has a streamlined, modern profile that still feels warm and human-centric. The facade opens up with hardwood-framed glass doors that can slide over to reveal its Scandinavian and Japandi-inspired interior. It can be partially closed off with a hardwood-encased screen door or a translucent curtain.

Australian studio TRIAS designed the unit in collaboration with prefab manufacturer FABPREFAB. The aim was to not only make architecturally designed homes more accessible and affordable but to make prefabs more widely appealing. “We did a lot of research into the Australian and overseas markets. In Australia, the emphasis tends to be on low cost, whereas in Europe the emphasis is on quality and longevity. This aligns perfectly with the philosophy of our practice. We wanted to create something consciously good quality, but also to explore how to make a prefab house not look like a prefab,” says Jennifer McMaster, Director of TRIAS.

Minima doesn’t need a concrete foundation and instead uses a special type of ground screw that can ease relocation if necessary which heavily reduces the impact on the construction site’s surroundings. Since it is a modular design, you can add an extra module in a T-formation to double the area. The impressive prefab home could fit almost anywhere there might be open space creating more opportunities to build accessible and affordable communities that can be scaled.

The compact floor area is divided into various zones that group different functions together. For instance, “wet” areas like the kitchen and bathroom are on one side of the micro-house while the living and sleeping areas are concentrated into one flexible zone in the center of the home.





The interior walls, ceiling, and floor are covered with lots of cross-laminated timber (CLT) – a sustainable engineered wood product that involves layers of fast-growth timber that are glued perpendicular to each other, resulting in a structurally robust and fire-resistant material that not only looks good but is also perfect for prefabrication.





Everything in the home has been intentionally made to look seamless.”Keeping all the joints and lines as simple and seamless as possible is important in a small space. We’ve lived in tiny apartment spaces, so we know how critical those lines are in making a space feel larger,” adds Jonathon Donnelly, Director at TRIAS.





In the living area, there is plenty of built-in furniture to help save maximize space, like this integrated seating bench, which also has storage space tucked below and above. Right in the center, there’s a wall-to-floor cabinet that actually has a bed, table, and shelving integrated inside. During the day, the bed can be folded away, and a multifunctional table pulled out for eating or working on. At night, the bed can be pulled down to reveal a sizeable queen mattress, as well as lighting and storage behind.





The kitchen features a pared-down countertop that has all the essentials of the sink, stove, oven, range hood, concealed refrigerator, and plenty of storage. Cross-ventilation is helped along with the addition of another small door off to the side of the kitchen, and which also functions as a secondary entrance. There is a bathroom behind the kitchen and past a pocket door. The slate-gray tiles, in combination with the CLT cabinets, create a soothing, calming atmosphere, lit with help of a skylight over the shower.





“Something that’s always stuck with us is a finding from a 2018 Grattan Institute report into Australian cities: ‘The quickest way to double density is to add something small to every existing block.’ Small insertions can help retain the suburban character while adding enormously to social cohesion and housing,” says the team and that wonderful sentiment is what we need right now to guide us away from skyscrapers and towards sustainable architecture.
