30' x 50' Modern Shed Roof Cottage Architectural Plans

The 30' x 50' shed roof cabin is the largest plan in the Lean Cottage series β€” 1,500 square feet across three bedrooms, two bathrooms, and an optional sleeping loft, all under a clean contemporary single-pitch roofline. At 50 feet in length this design has real room to spread out: bedrooms are well separated from the main living area, two full bathrooms eliminate guest conflicts, and the loft adds a fourth sleeping space without expanding the footprint. The shed roof style keeps framing straightforward and material costs predictable, which matters on a build this size.

Large windows run throughout for natural light, a large front deck extends the outdoor living space, and a washer/dryer hookup makes this fully functional as a primary residence or long-term rental. Three foundation options β€” concrete slab, concrete pier, and crawl-space β€” are included in the drawings, covering the full range of site conditions from flat lots to sloped terrain.
