About us

Greenheart Sustainable Construction is run and owned by Malcolm McMahon and Richard Hatfield. We work as a partnership, and have been trading since 2000, with sustainability at the heart of what we do.

Our expertise is in energy efficient building, and between us we have 60 years of building experience. We are passionate about what we do, and we believe that integrity and quality are vital for the success of any project we undertake.

We are primarily builders. Malcolm’s background is in design, while Richard’s is in engineering. We are both skilled and experienced carpenters.

We work in conjunction with a team of other builders, including people with skills in all aspects of building – from groundwork and stone masonry, to carpentry and roofing, and plumbing and plastering. Over the years, we have gathered together a team who share our values of sustainability and quality, and enjoy working together.

We have a regional focus, and you’ll find examples of our innovative, low-energy, sustainable construction in Bristol, Bath and Somerset, as well as i in Gloucester, Stroud and the Cotswolds.

We believe in the importance of building good relationships with those we work with, based on honesty and clear communication.
