The Hayloft

The Hawthorne Plan | 2-Bedroom Narrow-Lot Modern Farmhouse Plan

The ADU-2B-2B-1232 is a 1,232 sq ft, two-story accessory dwelling unit (ADU) plan with 2 bedrooms and 2 full bathrooms. Each floor has its own bedroom suite with a private bath and walk-in closet. The footprint is 21'-11" wide by 37'-10" deep, so it fits narrow urban lots, backyard ADU sites, and infill lots. A double-height vaulted living room and a board-and-batten gable exterior give it a clean modern farmhouse look.

Ground Floor Layout

You enter from the covered front porch through a wide three-panel glass door into an open-concept living, kitchen, and dining area. The ceiling here is vaulted to the full two-story height. The L-shaped kitchen fits a dining table for four. Past the kitchen are a main-floor bedroom suite with its own bathroom, a walk-in shower, and a walk-in closet. A mudroom with a side entry at the back holds the water heater, and there is under-stair storage.

Second Floor Layout

The stair leads up to a second private bedroom suite with a full bathroom, a walk-in shower, and a walk-in closet. There is also an open landing that overlooks the vaulted living room below.
