Custom A-Frame House Plans

The pure triangle — open living below, a sleeping loft above, and a glass gable facing the view. Simple, iconic and fast to build.

Shed dormers and a rear bump-out that reclaim the headroom a pure A-frame loses to its sloped walls, adding real bedrooms.

A full primary suite tucked into the loft with the glass gable as a headboard wall — the layout guests photograph most.

A daylight or walkout lower level on a sloped lot that doubles the square footage without changing the roofline.

Sized and zoned for nightly rental — a bunk loft, a hot-tub deck and a layout that sleeps more heads than its footprint suggests.

A conventional shed-roof extension off the back for the kitchen and bath, keeping the dramatic front while adding livable space.

In an A-frame the roof carries everything and takes the full snow and wind load. The rafter size, ridge and connections have to be engineered for your climate from the start.

The wall of glass is the whole appeal but drives heat gain, heat loss and egress. The plan sizes and specs it so the cabin stays comfortable and passes code.

How high the loft sits and how you reach it — stair, ladder or spiral — changes headroom, usable area and the feel of the whole space.

A-frames lose floor area to their sloped walls. A good plan puts storage, bunks and low furniture where the walls close in so nothing is wasted.

Where the gable points and how the cabin sits on the slope is the single biggest design decision — and the one a stock plan cannot make.

Most A-frames go up on raw land, so the plan has to place well, septic and power where they actually work with the site.
