10×20 A-Frame Cottage with Porch

The Cozy 10x20 A-Frame Cottage with Porch Built for Montana

The 10x20 A-Frame Cottage with Porch from Montana Custom Sheds is a spray-foam insulated build designed for year-round comfort and Montana weather.

With a classic A-Frame roofline and a steep 9/12 roof pitch, it sheds snow and rain efficiently while giving you excellent interior headroom. The cottage is built with 7′4″ walls and 16″ on-center framing for long-term strength and durability. LP SmartSide siding with timber bark trim, paired with a crinkle burn slate metal roof, creates a rustic, finished look that holds up beautifully over time.

Inside, the cabin is fully insulated with 2″ spray foam insulation in the floors, walls, and ceiling, helping regulate temperature in both hot and cold seasons. (3) 30″ × 36″ windows and (1) 24″ × 27″ insulated vinyl window bring in plenty of natural light, while 6′ × 6′ double doors make it easy to move furniture, equipment, or gear in and out.
