Greenheart specialises in low-energy, high-performance sustainable design & build.
Based in Bristol and serving the South West since 1999, we take a flexible, collaborative, human-centred approach to design and construction. We work closely with residential and commercial clients at every stage, whether that’s early concept and planning, technical detailing and certification, cost management or construction.

Sustainability is at the heart of everything we do.
We’re one of the few companies in the South West to offer a fully integrated package of PHPP (Passive House Planning Package) and Design & Build services. This is complemented by our role as regional installers of WARMCEL insulation and our trusted partnerships with suppliers of the highest quality materials.

Over two decades of experience leading the way.

We’re proud to deliver beautiful, climate-conscious buildings that meet the highest standards of energy efficiency, comfort and craftsmanship. Our respectful, collaborative approach is valued by our clients, with many remarking how much they enjoy having our team on site.
