Box-Built ADU Plan with 2-Bedrooms and ADA Accessibility

Boxes System Build Option
With the Boxes System, the structural shell is framed off-site as transportable modules, each shipping on a standard hot shot trailer within DOT limits — no oversize permits required. Modules arrive with ZIP System sheathing, roof decking, windows, and exterior doors pre-installed. A small crane and three-person crew can set and seal the home in under a day, with local contractors ready to begin the very next morning. Standard permitting and inspections apply throughout.
Spec'd for Net Zero Ready performance — built for low operating costs and comfortable living. Visit boxesbuilt.com to learn more.

About This Plan

This 2-bed, 2-bath modern cottage delivers 700 sq ft across two stories — 433 on the main level and 267 above — with a fully accessible main floor designed to ADA wheelchair standards. A stacked-box silhouette with two-tone board-and-batten siding and a low-slope shed roof gives it crisp contemporary lines while keeping construction efficient.

The main level is built around a wheelchair-accessible bedroom suite, pairing the primary bedroom with a full bath featuring an ADA roll-in shower and wide clearances throughout. A galley kitchen runs along one side, with a compact laundry closet tucked beside the crawl space access. The living area opens to a covered front porch under 8' ceilings, and a shelving nook between kitchen and living adds display or storage without eating into the floor plan.

Upstairs, a second bedroom anchors the front with easy room for a queen bed, while a flexible loft/guest space and second full bath share the upper floor — the loft works as a home office, reading nook, or overflow sleeping for guests. An open-to-below detail at the stair landing keeps sightlines connected to the main level and makes the footprint feel more generous than the numbers suggest.
