Buildings

Our pre-permitted and predesigned multi-family housing buildings and planned communities and villages are carefully designed to be low-risk, low-cost, and low-maintenance. Our premade buildings are attainable, sustainable, and beautiful, so everyone can own a home they truly love.

Vertical Development

Multi-Family Housing

Quantum’s Universal Building Blocks are stackable to create apartment and condo buildings up to five stories tall. Our customizable rooftop options can provide shared outdoor environments to foster a sense of community, even when space in the neighborhood is limited.

Horizontal Development

Planned Communities

Our planned communities are sets of standalone homes for individuals and families — these can easily range from studios to two-bedroom, two-bath homes based on the community’s needs, whether they’re students, seniors, veterans, or a local workforce. We can ship and install a village in weeks.

Floorplans

Our predesigned floorplans range from 400-square-foot studios to 800-square-foot two-bedroom, two-bath units. These can be installed as standalone homes or assembled into a multi-unit structure using any combination of floorplans.
