On Blakely Island in Washington’s stunning San Juan Island Archipelago, Seattle-based architecture firm Wittman Estes has crafted a 400-square-foot guest cabin that perfectly balances compact design with breathtaking surroundings. Suspended on stilts amongst towering Douglas firs, the cabin overlooks the serene Salish Sea, nestled between a massive glacial erratic boulder and a mature Douglas fir tree.

Inspired Design and Clever Space Utilization

Drawing inspiration from iconic structures like Thoreau’s Walden Cabin and Le Corbusier’s 1952 Cabanon, the 16-by-20-foot cabin embodies the charm of a tiny house in the woods. Inside, function meets efficiency with a small kitchen, a Murphy bed, a bathroom, and a loft with two bunks. Every element within this open studio serves a purpose, while the expansive views through the large glass doors create an illusion of spaciousness.

Building In Harmony with Nature

The cabin’s steep and rocky location posed significant challenges, both practical and ecological. To minimize the environmental impact, many components were prefabricated off-site in Everett. Bringing these pieces across water by barge allowed them to bypass the difficulties associated with transporting heavy machinery to this remote island.

This approach mirrors the ingenuity of Bangkok’s Pridi41 House’s design, which integrates natural elements within an urban environment.

The structure’s modular steel frames fit into a minimal point foundation, while its Western red cedar siding, milled from trees on site, will gracefully weather with time.

An Elevated Retreat in the Trees

The cabin’s stilt-based elevation is a bold architectural statement. It hovers above the challenging terrain, preserving the natural landscape beneath. This raised design ensures that the cabin’s footprint leaves a gentle touch on the forest floor of this wooded sanctuary.
