20' x 28' Modern A-Frame Cabin Architectural Plans

20' x 28' Modern A-Frame Cabin Architectural Plans

The 20' x 28' Modern A-Frame steps up the A-frame formula with 690 square feet, two bedrooms, and a full concrete slab foundation — more room, more stability, and more flexibility for year-round living. This is the A-frame plan for buyers who want the iconic look without compromising on livability.

The main floor open-plan layout keeps the kitchen, dining, and living areas connected beneath soaring vaulted ceilings. Both bedrooms are positioned for privacy, and the overall footprint is efficient enough to keep construction costs in check while delivering a finished cabin that photographs beautifully for short-term rental listings.
