Fernwood Bunkie Kit: 40 mm Walls Under the Permit Radar
The Fernwood answers a specific question: how much building can you get below the common 108 sq. ft. permit threshold? Answer: 107 sq. ft. of solid 40 mm log construction — the same wall spec as our biggest cabins — with wide 2′11″ eaves for real weather protection. (Always confirm your local bylaws.)
Why you’ll love the Fernwood
- 107 sq. ft. with 40 mm walls: maximum solid-log building within the common no-permit footprint.
- 40 mm solid spruce walls: the substantial, quiet feel of a proper cabin, not a garden shed.
- Restrained gable roof: 8’0″ (245 cm) ridge height, generous 2’11” (90 cm) eaves.
- Openings: 1 person-width entrance, 1 window.
Best suited to
A three-season guest room, office or studio where you want proper walls without the permitting process. The generous eaves keep rain off the logs, extending the finish life.
Built to go up in a weekend
Precision machining does the hard work before the kit reaches you: each slow-grown Nordic spruce log is cut and profiled to interlock exactly. A typical two-person crew raises the shell in 1–2 days with basic tools, guided by numbered parts and clear instructions.
