What it is
My Capstone Box places finished container amenity rooms, like a fitness room, a co-working space or a resident lounge, on apartment and commercial properties in Massachusetts, often in the footprint of a parking space.
Most properties have no spare room for a gym or a shared workspace, but they do have a parking spot. A container amenity space sits there as a finished room: insulated, climate controlled, with glass doors, lighting and the equipment the use needs.
One footprint, several possibilities. The same unit can be a resident fitness room, a quiet co-working office, a package or meeting room, or a lounge.

What's inside
- Fitness: rubber floor, mirror wall, TV, equipment space
- Co-working: desks, monitors, task chairs
- Lounge: seating, TV, coffee station
- Climate control and LED lighting in every unit
Who it's for
- Apartment complexes adding resident amenities
- Property managers competing on amenities
- Commercial properties that need a room outside the building

Questions people ask
How much space does it need?
The units are built from shipping containers, so the footprint is roughly a parking space or two depending on the size. We look at the spot with you first.
How fast can a unit be ready?
Each unit is a shipping container retrofitted in a modular-building facility. The build-out takes under 30 days from the start of the build.
Is there a long-term contract?
No. Units are rented month to month, so you keep it for as long as the project or the lease-up needs it.
