A few words About us

We are designers, with degrees in architecture, turned green home builders. We had been designing sustainable energy-efficient homes for over 15 years. We started Theta Homes because we wanted to bring good design and quality construction that caters to the lifestyle of modern living and energy efficiency directly to homeowners.

We are EarthCraft certified Class A contractor, plus we are designers. So, you can be rest assured your home will be built with the highest standards of energy efficiency that will lower your utility bill, give you better indoor air quality, increase comfort, reduce home maintenance, and best of all, enjoy your home.

A house is made with walls and beams; a home is built with love and dreams

Passionate about promoting better design and energy-efficient construction

Soumitra Banerjee moved to the US from India in 1986 after completing his Bachelors in Architecture from Jadavpur University in Kolkata (formerly Calcutta). He graduated from Virginia Tech (go Hokies!) with a Masters of Science in Architecture degree. Since his very first job he has adopted Richmond as his place of residence and has been living here with his beautiful wife and two adorable children - once a Virginian always a Virginian!

Soumitra started a design firm, Banerjee & Goff, in 1992 providing architectural services, space planning and retail design. List of clients include Circuit City, Belk, Advance Auto Parts, Ferguson, Virginia Supportive Housing, and Southside Community Development & Housing Corporation to name a few, many of whom are still his clients. He gradually broadened his services to include home design since the late 90s and started Theta Homes in 2013 to provide custom design and energy-efficient construction services.

Soumitra has always been open-minded about learning new things and this aspect of his personality has turned him into an innovation expert and entrepreneur. His proficiency with technology and its innovative use in home-building is what he loves to demonstrate through his work at Theta Homes. He is not only a partner in the company but a designer and energy efficiency expert par excellence. He also has a wealth of experience in project management, energy-efficient solutions and construction technologies.

He is a great listener and is always open to new ideas that would make a home more efficient and sustainable. You will enjoy meeting him and trusting him with the project of your dreams.
