75'x70' Modern House Plan with Loft and 2-Car Garage, 4 Bed / 2 Bath, 4,345 sq ft

This 75' x 70' modern cabin house plan delivers 4,345 sq ft of living space across 1.5 stories, pairing a low-slope contemporary roofline with the warmth of a traditional cabin layout. Five bedrooms, two full bathrooms, an attached two-car garage, and more than 1,100 sq ft of covered and open outdoor living make it one of the most spacious cabin-style designs available as an instant download, and the open-concept core keeps the whole footprint feeling connected rather than chopped into rooms.

The main living space runs the width of the home, with a 23'6" x 18'0" living room anchored by a fireplace and TV wall that opens directly into a 23'6" x 10'6" kitchen with a full center island, a matching 23'6" x 10'6" dining area, and a 9'0" x 8'6" breakfast nook. A 5'6" x 8'0" walk-in pantry sits just off the kitchen. The master suite occupies its own wing with a 17'6" x 11'6" bedroom, a 12'0" x 11'6" en-suite bath, and an 8'3" x 7'0" walk-in closet reached through a private entry vestibule. Two secondary bedrooms at 10'6" x 11'6" each share a 6'6" x 9'6" full bath and have their own closets, while a 33'-long central hallway keeps circulation clean and quiet. Upstairs, two loft bedrooms measuring 17'6" x 12'0" and 10'6" x 14'0" add flexible space for kids, guests, or a home office. A 5'6" x 12'0" laundry room, 29'0" x 22'0" garage, 23'0" x 27'0" carriage porch, 9'6" x 30'0" covered rear porch, and a full-width 12'0" x 70'0" deck round out the plan.

Construction is conventional wood stud framing with insulated 6" exterior walls clad in wood siding, 6" interior partitions, and 6x6 structural columns supporting the porches and open spans. The home sits on a concrete 6" slab foundation with perimeter footings set 2'-6" below grade, and the roof runs a 1"/12" low-slope pitch to a total building height of 17 ft, with the loft floor at the 10 ft level. Drawings specify energy-efficient windows, a 200A electrical service with LED lighting and hardwired smoke and CO detectors, and PEX or copper supply with PVC drain and vent piping fed by a 40-gallon water heater.

This design suits growing families who need real bedroom count without a second full story, buyers building a large vacation or lake property, and short-term rental investors who want sleeping capacity plus generous outdoor entertaining space. Owner-builders will appreciate the included material schedules, which give framing, column, and wall quantities for accurate lumber yard pricing.

Plans are drawn to California residential codes and are not sealed. A licensed engineer in your jurisdiction should review the set before permitting or construction, since local wind, seismic, and foundation requirements vary.
