Working in Bristol and the South West, Earthwise Construction provides full construction services for Passive House/Passivhaus new builds and EnerPHit retrofits.

While we don’t offer in-house PHPP design, we have good links with passive house designers, who can help you with design consultancy and advice at all project stages – from initial feasibility and planning applications to full design using the Passive House Planning Package PHPP.

Why choose us to build your Passive House project?

At Earthwise Construction we realise the importance of choosing the right insulation material and installing in line with the Passive House methodology, to ensure that we minimise thermal bridges and don’t create issues further down the line. That’s why we send our team on the Passive House Tradesperson Course, to ensure they have the most up to date training in the field.


Unwanted draughts are a major source of heat loss in buildings. If you choose to work with us you can rest assured that, with our in-depth knowledge in airtightness installation techniques, we can work with you to come up with a solution that works for your property and budget.

We have many years’ experience in achieving excellent levels of airtightness, reaching levels of 0.1 ACH. We always appoint an airtightness champion on our sites to ensure we get great results.


As you make your new build or retrofit project more airtight/wind tight it is important that there is a ventilation strategy in place, as many issues can occur if this is not addressed at the same time.

We can advise you on appropriate ventilation strategies for your property, and we are experts in the installation of Mechanical Ventilation with Heat Recovery (MVHR). Click here to find out more.
