One of the U.K.’s Most Impressive Prefab Builders Just Launched a $58K Sauna

Welcome to Prefab Profiles, an ongoing series of interviews with people transforming how we build houses. From prefab tiny houses and modular cabin kits to entire homes ready to ship, their projects represent some of the best ideas in the industry. Do you know a prefab brand that should be on our radar? Get in touch!

U.K. design firm Koto was founded by Johnathon and Zoe Little and Theo Dales in 2017 to provide nature-inspired spaces that enhance an overall sense of well-being. Their prefab residences, hospitality-focused turnkey cabins, and now, a sauna designed in collaboration with Out of the Valley (which has one of its own), aim to better connect people to their natural environments with sleek, minimalist interiors that keep an emphasis on the outdoors. Here, Johnathon shares one of the company’s favorite builds, and fills us in on the new Jōki Elements sauna.

Tell us about the new sauna.

The Jōki Sauna (jōki meaning "steam" in Japanese) is an outdoor, modular sauna cabin. It’s part of our Elements series, which also includes a hot tub, that aims to redefine relaxation and wellness in natural settings. Combining the architectural expertise of Koto in creating sustainable design-led structures with Out of the Valley’s mastery in crafting stunning timber cabins, the result is a fusion of design and function that we hope will enhance the wellness industry.

What’s the most exciting project you’ve realized to date?

Among the array of exciting Koto projects we have delivered to the private and hospitality sectors, one that has truly captivated our hearts is the KotoHouse in North Uist. This venture, realized for a private client seeking a family home, holds a special place in our journey. Set against the backdrop of the rugged North Uist landscape, this dwelling stands as a testament to our design-led philosophy.

The unique charm of this project lies in its seamless integration with the Hebridean landscape. The home has been thoughtfully positioned to command breathtaking vistas that change with the moods of nature. The client’s vision aligned perfectly with our principles of connecting people with their surroundings while providing a haven of comfort.

While all our projects hold a special place in our creative journey—from hospitality cabin projects to exclusive homes—ventures like Koto House in North Uist showcase the transformative power of design and its ability to create spaces that not only meet practical needs but also inspire its inhabitants.
