The home
The Duet at a glance
The Duet puts two full-size family homes under one simple roof. Each home has its own front door, its own rear yard and its own parking. The main floor runs open from front to back: living room at the street, dining in the middle and an L-shaped kitchen at the rear, with a powder room, utility room and under-stair storage. A rear entry comes in from the yard and parking. Upstairs, the king-size primary suite has a walk-in closet, a private ensuite and a study alcove. Two queen bedrooms share a full bath, and the laundry room sits on the bedroom floor. The second home is an exact mirror. Charcoal siding, a light lower front and warm wood at the entries and rear give the building a clean, modern look. Site layout, the separation wall between homes and finish selections are developed for each project.

How it's built
The Duet, built with panelized construction
MBS builds The Duet from factory-made wall panels, floor cassettes and roof panels, CNC-cut in our St. Louis plant to the approved drawings. Panels ship flat and are set on a conventional foundation. The finished home is wood framing, not a modular box or a manufactured home, with a 50% quicker construction schedule.
Pick your package
Framing only, open or sheathed panels, or closed panels with windows, cladding and MEP rough-in.
Keep your crew
Your framer sets the panels, or MBS coordinates installation with your GC.
Fixed price, standard trucks
