Proto Homes are a a hybrid between prefab and built-on-site homes. The shell and core features of the home are produced in the factory, while the rest of the home is built on site for a more customizable and sustainable take on the traditional prefab.
The Proto Core is prefabricated in a factory and contains the guts of the home, including the home's mechanical, plumbing and electrical sources. All of the plumbing, ducts, wires, and hardware are exposed and easily accessible and upgradeable within the core. Every room in the home backs into the core for a direct connection to plumbing and electricity. It also serves as a major structural support element.
On average, Proto Homes can be constructed and erected within 4 months, in line with many prefabs and far quicker than any traditionally built home. A few other unconventional features include a zero penetration roof that's uninterrupted by plumbing vents or ducts, and also doesn't contain a traditional attic for higher ceilings.
Bathtubs are reworked into Soak In Showers, similar to baths designed for older adults.
