25'x32' Modern Cottage Floor Plan, 2 Bed / 2 Bath, 800 sq ft

This 25'x32' modern cottage house plan delivers 800 sq ft of heated living space across a single level, pairing a steep gable roof and clerestory gable glazing with an open living, kitchen and dining core that makes a small footprint feel considerably larger than its square footage suggests. Two bedrooms, two full bathrooms, a fireplace, in-unit laundry, and a 20'x8' covered-front patio fit into a rectangular 25 ft wide by 32 ft deep shell that is straightforward to frame and inexpensive to foundation, which is exactly why this footprint works so well for tight infill lots and rural acreage alike.

Inside, the living room measures 9'11"x13'4" and centers on a fireplace flanked by full-height built-in cabinets on both sides, opening without a wall break into the kitchen and dining area at 10'11"x13'4", where an L-shaped counter run holds the range, refrigerator, and sink with room for a four-seat dining table. A short 3'4" central hall separates the public and private zones. The master bedroom sits at 10'6"x10'9" with direct access to its own 8'3"x6'3" en-suite bath with a dual vanity, while bedroom 2 measures 9'6"x10' with a dedicated closet wall and sits alongside the 9'6"x4'7" family bath, which carries a full bathtub. Between the two bedrooms you get a stacked washer and dryer closet plus separate linen and storage space, so nothing spills into the living area. Both bedrooms comfortably accommodate a queen bed.

Structurally, the plan is drawn for a concrete pier and footing foundation with treated 2x6 sill plates and 2x10 floor joists, carrying 2x6 exterior stud walls with insulated cavities and a rain-screen assembly behind 7" board siding. The roof runs on 2x10 rafters to a 17'-4" ridge with an 8'-0" opening level and a 10'-11" clerestory level, finished in black corrugated metal over plywood decking with a fully adhered membrane at the eave perimeter. The drawing set includes several alternate insulated roof assemblies, so you can build unvented with insulation above the deck, in the rafter cavity, or on a raised truss depending on your climate zone. Electrical drawings specify GFCI protection and interconnected hardwired smoke and CO alarms; plumbing drawings specify Type M copper supply and PVC Schedule 40 drain and vent.

The single-level, no-stairs layout with two full baths makes this a strong candidate for a backyard ADU or accessory dwelling, a long-term or short-term rental, a guest house or in-law suite, or a genuine primary residence for downsizers and retirees who want accessible living without a hallway of unused rooms. First-time owner-builders tend to gravitate toward this size because the framing is uncomplicated, the material list is short enough to price accurately, and the total build sits in a range most people can finance without a construction loan.

Plans are drawn to the 2022 California Residential Code (IRC 2021 with amendments) and do not meet earthquake seismic or high-wind code requirements. Many jurisdictions require a locally licensed engineer or architect to review and seal residential drawings before permits are issued, and foundation design in particular should be verified against your site's soil conditions and frost depth. Check with your local building department before purchasing so you know what additional review, if any, your project will need.
