30'x25' Modern Tiny Cabin Floor Plan 1 Bed 1 Bath, 750 sq ft

This 30'x25' modern tiny cabin house plan delivers 750 sq ft of open, light-filled living wrapped in a clean gable roofline, with a full-width covered front porch and a bonus loft that stretches the usable space well beyond its footprint. Raised on a pier foundation, it's a small home designed to feel intentional rather than cramped, with the living space, sleeping quarters, and outdoor room all pulling their weight.

Step inside and the open living and dining area measures 11' x 16'4", running front to back so natural light reaches deep into the room, with the galley kitchen laid out along one wall complete with range, sink, refrigerator, and full cabinetry detailed in plan and section views. The bedroom is a generous 10'1" x 16'4", large enough for a queen bed with room to spare, and includes closet storage. The full bathroom comes in at 7'7" x 6'10" with a tub, vanity, toilet, and a dedicated washer and dryer closet, so laundry never leaves the house. Above it all, a stair-accessed loft adds flexible bonus space for sleeping, storage, or a reading nook, and the 30' x 8'3" covered porch runs the entire width of the front elevation, adding nearly 250 sq ft of true outdoor living.

Construction is straightforward and owner-builder friendly: a concrete pier foundation with 10" diameter drilled piers, treated posts, and a raised wood floor framed in 2x10 joists, which makes this plan a natural fit for sloped, wet, or rural sites where slab construction gets expensive. Walls are conventional 2x4 stud framing with insulated assemblies, the gable roof is framed with 2x10 rafters and detailed for either corrugated metal or asphalt shingles, and ceilings reach 13 ft at the interior with an overall building height of 21 ft 6 in. The set includes five different vented and unvented roof insulation assemblies, full electrical and plumbing plans, step-by-step window flashing details, and an itemized material list, all designed to IRC 2021 residential standards with wind loads per ASCE 7-16.

This plan is a strong match for anyone building a backyard ADU, a guest house or in-law suite, an Airbnb or vacation rental, a hunting or lake cabin, or a right-sized full-time home for downsizers and first-time owner-builders who want a complete, buildable drawing set without hiring a design firm.

Please note that plans do not meet earthquake seismic or wind code requirements, and many jurisdictions require review and sealing by a licensed local engineer or architect before permitting. Check with your building department before purchasing, and have all spans, framing, and foundation details verified locally before construction begins.
