Make modern modular spaces faster, smarter, and more accessible — from backyard garden rooms to scalable modular housing solutions.
Garden Room 158.
A compact 158 sq.ft backyard room designed for flexible everyday use — home office, studio, gym, lounge, hobby room, kids’ activity space, or a private backyard retreat. One shell, many lives.
Built with Boxway Aluminum SIP.
Boxway uses advanced aluminum Structural Insulated Panels (SIPs) to create a durable, energy-efficient, and fast-assembly building system. The same engineering principles used in modern homes — sized for your backyard.
-
01
Faster installation
Pre-engineered panels arrive ready to assemble on prepared footings. A small team can typically finish in a few days — not weeks or months.
-
02
Strong thermal performance
The aluminum SIP envelope insulates against summer heat and winter cold without bulky framing, giving year-round comfort with modest heating and cooling loads.
-
03
Modern design
Clean lines, full-height glazing, and durable panel finishes that complement contemporary and traditional homes alike — without looking like a backyard shed.
-
04
Reduced on-site complexity
Less framing, less trade coordination, less weather risk. Most of the engineering happens offsite, so what arrives at your backyard is a kit, not a construction project.
