Icicle Creek Cabin by CAST Architecture is a high-mountain, off-grid retreat located on a private inholding in the Wenatchee National Forest. Built to thrive in heavy snowfall and extreme temperature swings, the cabin sits on an unwooded knoll to protect the existing site. Its design is pragmatic, durable, and energy efficient.
Thoughtful, Functional Entry
Access to the cabin is seasonal—reachable by snowmobile or skis for half the year. The ground-level entry features ski racks, utility space, and a wood-burning stove that provides overall heat and dries gear. At the top, a spacious covered entry and a hard-working foyer offer plenty of room to shed winter gear. The adjacent laundry room and integrated drying hooks around the stove enclosure further serve the needs of outdoor enthusiasts.
Panoramic Views and Open Living
Beyond the entry, the main level opens to stunning panoramic views. Floor-to-ceiling glazing in the living room and kitchen creates an uninterrupted view of the mountain ridge. The architects placed window mullions low so that they do not block the scenery. A generous covered outdoor porch on the uphill side provides deep shade during the summer and unexpected views downslope to the river. This arrangement gives the great room a “treehouse” perspective of the valley and ridgeline without any visual barriers.
Warmth and Comfort Throughout
Wood stoves lie at the core of the house on each level to distribute heat quickly. They warm the common areas and bedrooms, making the cabin ideal for weekend getaways or holiday retreats. A reading nook doubles as a daybed on the stairwell landing to offer extra sleeping space. A bunk room with four sets of bunk beds and ample space comfortably sleeps at least six guests. Each floor also features a beautifully designed bathroom that resists freezing. One level offers a luxurious wet room with a sunken tub and scenic views, while the level immediately below boasts an equally attractive shower room.
Robust, Energy-Saving Structure
A straightforward shed roof collects snow, which acts as free insulation and reduces the risk of avalanches. The concrete base sits above the average snowfall line, protecting the siding and wood framing from freeze-thaw damage. The exterior avoids exposed wood, which enhances fire protection.
Green, Off-Grid Solutions
The cabin incorporates robust off-grid systems. An 8kW solar array sits away from the house to optimize energy collection. A battery bank and sophisticated power management system keep the lights on during long winter nights. A 70,000-gallon cistern allows a low-producing well to supply both domestic water and reserve water for wildfire response. Energy efficiency is further enhanced by double-pane windows with low-E coatings.
In summary, Icicle Creek Cabin marries practical design with sustainable technology. It offers an off-grid retreat that meets the demands of a harsh mountain environment while providing comfort, breathtaking views, and robust environmental performance.
