28' x 46' Large Modern A-Frame Cabin Architectural Plans
The 28' x 46' Large Modern A-Frame is the flagship of our A-frame lineup — 1,400 square feet with three bedrooms, two bathrooms, a full loft, and a roofline that peaks at over 29 feet. This is the plan for buyers who want maximum A-frame impact: striking from the outside, breathtaking from inside, and fully functional as a year-round residence or premium vacation rental.
The elongated footprint gives this design room to breathe in a way that smaller A-frames can't. Bedrooms are well separated, the two-bathroom layout eliminates morning bottlenecks, and the loft overhead adds sleeping or flex space that keeps guests comfortable in a rental context. The concrete pier foundation handles sloped sites and challenging terrain without heavy earthwork.

Designed for buyers who want a large A-frame that works as a primary mountain residence, a multi-family vacation property, or a high-performing short-term rental.
