“Symbihom's process could be a game-changer for office-to-residential conversions that have proven to be difficult and costly. It could be easier for cities with desperate housing needs — like San Francisco — to add housing.”

New Living Space Means New Possibilities

  • Whether it's a private studio, family living area, or home office, Symbihom provides the freedom to design spaces that perfectly match your needs.

  • Smaller, efficient housing solutions require fewer materials and resources to build and maintain. This downsized living approach is not only affordable to build but also better for the environment.

  • Homeowners and commercial real estate developers can rent out their converted rooms, garages or backyard additions providing an excellent additional stream of income.

  • Each unit is thoughtfully designed with high quality, durable materials that stand the test of time. From sleek scratch-resistant countertops to elegant, easy-to-clean flooring, every detail is chosen for both style and longevity.
