Single Family Homes, Accessory Dwelling Units (ADUs), Commercial, Multi-family and Emergency Housing.

“Prefab” is a general term used for a prefabricated building or building component that is manufactured in a factory prior to its final assembly at the construction site, whereas “Modular” refers to something built or organized in self-contained units—like building blocks. We offer both types of buildings.

ARCspace units have a one-year warranty for interior components and a three-year warranty for exterior components.

We have fire-resistant recycled plastic (in many different styles) that is 30% less expensive than TREX. We also have metal and farmhouse style options available, made with recycled faux-wood. In non-fire areas, we have a range of metal and wood cladding. The only limit is your imagination.

Yes. ARCspace interiors are fully customizable, flooring, countertops, fixtures, paint, everything. Our team will work with you to ensure that your unit reflects your unique style. (Certain options come at additional cost.)

Yes. We utilize environmentally-friendly, plant-based spray foam insulation from JohnsManville and others. We have also partnered with Drywired, a Los Angeles based nanotech company, who delivers eco-friendly protective thin-film coatings. These are sprayed onto the ARCspace windows and make our buildings more energy efficient, surfaces cleaner and lessens e-waste. In short, our buildings have the necessary insulation for cold, mountain applications and humid, tropical island applications.

HVAC options are available for ARCspace units. You will have choices on the type of heating and air conditioning that you require.

Yes, when the foundation is laid for your unit, the plans will indicate where the sewer lines will be connected. If a public sewer is not available at your site, you may be able to use some of our waste management systems or a septic tank (at an additional cost). We also have additional water treatment solutions, available at an additional cost.

In recent years, we have seen wildfires ravage our forests, towns and neighborhoods. We believe that steel modular construction is the answer to protecting housing losses from fire. While no building can claim to be “fireproof,” our fire resistance is unparalleled. The only vulnerability to fire for an ARCspace building is the windows. The unit can be designed with steel window coverings to protect the building and items inside.

Our units are built to meet and exceed California seismic safety requirements. Being made from steel, the structures are far less vulnerable to seismic damage.

Yes, the steel structure of an ARCspace unit makes it much more resilient against high-speed winds.

No. We do not use shipping containers. Housing made from shipping containers can contain materials known to cause cancer and other severe illnesses, such as lead paint, DDT wood flooring and most are sprayed with toxic insecticide coatings. California and other states have now banned their use.

ARCspace was initially created in collaboration with the most innovative Green tech companies in the world. We will continue working to provide the most cutting edge green technology in our units. Further reading of our PR our clean-tech partnerships like HydroLoop and TIM will give more advanced detail.

ARCspace is made with durable, responsibly-sourced steel. Not only does steel last longer than wood, it is also able to be recycled and repurposed.

While ARCspace will produce “One-Off” projects, we are mostly seeking developer partnerships as ARCspace largely targets larger multi house production opportunities. If your question wasn’t answered here please feel free to send us a note via our contact form.
