Our Founding

Born into a family that’s been building homes for 65 years, and with 35 years of acquired industry experience himself, Darrel McMaster is a confirmed Master Builder. However, more than just your typical Master Builder, Darrel is also a sustainable custom home construction specialist, and in 1980 he founded Sustainable Homes, Inc. with the goal of building stunning custom homes with a difference. Rather than just moving into a new space, buyers of these homes effectively move into a new way of life, their properties outfitted with the latest advances in sustainable systems; technologies that work with nature to ensure that more good than harm is being done to the environment.

A Sustainable Transition

Nearly four decades later, Sustainable Homes, Inc. has established itself as the national leader in building fully sustainable, third party-verified homes. In the last three years alone, Sustainable Homes has built over 50% of the highest scoring verified homes (as rated by the National Association of Home Builders Green Building Program) in the state of Texas, and 10% nationally.

Our latest net zero energy home, which we call our Point Source Home, has set an even higher standard for energy-efficiency, with features that include:

  • 100% Rainwater Harvesting for all household water needs
  • Aerobic septic system/on-site waste-water
  • Geothermal HVAC
  • An enhanced (PV) Solar Array to power the owner’s Electric Vehicle

Building the Future

Imagine! A net-zero energy home that, in addition to handling all of the household’s energy needs, is also equipped to power the owner’s vehicle. It is futuristic innovations like this that have positioned Sustainable Homes, Inc. as a thought-leader in the field of sustainable construction systems, materials and techniques. We are proud of our homes and the way they enable Texas families to live so lightly on the land. Our goal is to continue perfecting our knowledge of sustainable building technologies and to keep getting better at what we already do best:

“Building Tomorrow’s Homes Today.”
