22'x33' A-Frame Cabin Floor Plan 2 Bed 1 Bath with Loft, 875 sq ft

This 22' x 33' A-frame cabin house plan delivers 875 sq ft of conditioned living space across two levels, with a dramatic full-height glass gable and a side wing extension that solves the biggest problem most A-frames have: it puts a real bedroom and full bathroom on the ground floor instead of forcing everyone up a ladder. The result is a small cabin that looks like a classic Adirondack retreat from the outside but lives like a proper two-bedroom home inside.

The ground floor holds 807 sq ft and opens directly into a combined living and kitchen area positioned under the glass gable, so the tallest, brightest part of the cabin is the space you actually spend time in. The kitchen area measures 8'6" x 7'2" with a compact galley run along the exterior wall, keeping plumbing and appliance loads on a single side. The primary bedroom sits in the side wing at 10'9" x 7'2", tucked away from the main living volume for privacy, with the full bathroom at 9'7" x 7'8" including a tub or shower, vanity, and toilet laid out to IRC and ADA clearance guidance. A staircase leads to the 68 sq ft loft bedroom at 9'2" x 7'8", set at a 9'11" loft level with its own window and a view down into the living space below. A 6' x 8' sliding glass door connects the main floor to the outdoors.

Construction is a concrete pier foundation with 10" x 10" drilled piers and 8" thick footings, which makes this plan a strong fit for sloped, rocky, or wooded lots where a full slab would be expensive. Walls are 2x6 fir framing with batt insulation and a vented rain-screen cedar siding assembly; the roof runs on 2x10 and 2x12 rafters clad in black corrugated metal, reaching a peak of 22'7" with the secondary wing roof at 18'4". The drawings include multiple unvented attic insulation assemblies so you can match rigid polyiso or closed-cell spray foam to your climate zone.

This plan suits owner builders putting up a weekend cabin, hosts building a short-term rental where the A-frame silhouette does half the marketing, families adding a guest house or ADU on an existing property, and downsizers who want two separate sleeping spaces without the maintenance of a full-size home. The pier foundation and modest footprint also make it practical for remote or off-grid sites.

These drawings are prepared to 2022 California residential codes with wind loads per ASCE 7-16 and are not stamped or sealed. Snow loads, seismic requirements, and foundation standards vary widely by location, so have a licensed engineer or architect in your area review the set before you pull a permit or begin construction.
