Welcome to Earthwise Construction – Bristol’s specialist Passive House builders and MVHR experts.

With over 18 years of sustainable construction experience, we deliver high-performance buildings across Bristol and the South West, working with homeowners, architects, developers and businesses. We provide a fully integrated design-and-build service, covering every stage of a project—from concept and detailing to construction, commissioning and aftercare.

Our team specialises in:

• Certified Passive House (Passivhaus) construction

• Timber frame new builds

• Deep, whole-house retrofits to EnerPHit standards

• Airtightness, insulation and fabric-first detailing

MVHR Expertise – Design, Supply, Installation & Commissioning

As a Top-Tier Zehnder Service Partner, we offer a complete in-house service for Mechanical Ventilation with Heat Recovery (MVHR) systems throughout England and Wales. Unlike many competitors, we never subcontract key stages—our trained team handles:

• MVHR design

• MVHR supply

• MVHR installation

• MVHR commissioning

• MVHR servicing and maintenance

This end-to-end approach ensures the system is perfectly integrated with the building fabric and Passive House performance targets.

We also design and install Demand Controlled Ventilation (DCV)—a smart, cost-effective option for renovation projects or homes where MVHR may not be suitable.
