The home
The Perch at a glance
The Perch puts a complete one-bedroom home above a single-car garage. A straight exterior stair on the right side rises from the alley apron to a landing at the apartment door. Inside, the entry opens to a living and dining room across the front with the kitchen beside it. The bedroom has a built-in wardrobe. A bathroom with a walk-in shower and a laundry closet with a stacked washer and dryer complete the floor. Below, the garage holds a compact car, with a storage room and a utility room at the back.

How it's built
The Perch, built with panelized construction
MBS builds The Perch 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 ADU is wood framing, not a modular box or a manufactured home, with up to 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
