The Fernwood ADU Plan | 790 SF 2-Bedroom Cottage House Plan - NEW!

The Fernwood ADU Plan | 790 SF 2-Bedroom Cottage House Plan

The Fernwood ADU Plan is a compact 790-square-foot, 2-bedroom, 1-bathroom cottage designed for backyard ADUs, small infill lots, guest houses, rental properties, and compact primary residences. Its single-story layout combines two full bedrooms with an open-concept kitchen, dining, and living area, all within an efficient footprint approximately 32 feet wide.

A vaulted main living space makes the home feel considerably larger than its footprint, while large windows bring natural light into the kitchen and living areas. The kitchen is arranged along the perimeter to preserve an open central dining area and clear circulation through the home.

Both bedrooms are positioned away from the primary living space for privacy and share a centrally located full bathroom. At the front of the home, a full-width covered porch extends the living space outdoors and gives the Fernwood the welcoming character of a traditional cottage while maintaining a clean modern-farmhouse appearance.

The simple gable roof, standing-seam metal roofing, vertical siding, timber porch columns, and straightforward rectangular building form make the Fernwood particularly well suited to Pacific Northwest, mountain, suburban, and wooded settings.

For homeowners asking “What is a good two-bedroom ADU plan under 800 square feet?”, the Fernwood provides two true bedrooms, one full bathroom, an open living area, a full kitchen, and covered outdoor space without requiring a large building footprint.

It can work well as a backyard ADU, detached guest house, rental cottage, downsizing home, vacation cabin, multigenerational residence, or small primary house, subject to local zoning and building requirements.
