Welcome to Earthwise Construction,
a sustainable building and MVHR company based in Bristol.

With over 18 years’ green building experience, we work with home owners, architects, developers and businesses across Bristol and the South West, offering comprehensive eco design & build services, and specialising in Passivhaus (Passive House) timber frame new builds.

We also have a Mechanical Ventilation with Heat Recovery (MVHR) arm of the business, and have been installing MVHR systems for over 12 years across England and Wales.

Minimising environmental impact and maximising energy efficiency is at the heart of everything we do.

What we do

Kind words

  • Earthwise built our 4 bed detached timber frame, timber clad family home. They are exceptional builders who take great pride in their work and we feel very lucky to have found them.

    Ben Hooten – Timber frame new build
  • The work has been done to a very high standard. We love our house and are really glad that we chose Earthwise to rebuild our home. Clear knowledgable explanations were accompanied by neat carefully detailed work. The enthusiasm for environmentally sound building was really clear.

    Pete & Geraldine Giddings – Retrofit of Victorian house
  • 2nd year we have used Earthwise to service our MVHR system (air-source heat pump). Satisfied all round and would highly recommend them to others in the local area.

    Jonathan Flower – MVHR service
  • Earthwise ordered and installed our mechanical ventilation system efficiently and well – they arrived on time, worked hard and did a thoroughly good job.

    Gemma Fowlie – MVHR install
  • When we decided to replace our existing MVHR, we wanted somebody who would work closely with the design team and was aware of, and solve, all the install issues that would come up. Ben was that person. I would recommend Ben and his team for their thoroughness, politeness, and attention to detail, but the biggest praise I would give is that, without Ben, we wouldn’t have attempted the project in the first place.

    Av Bains – Replacement of MVHR system
  • Ben and the Earthwise Team did an excellent job. We needed a replacement MVHR unit and they found the right unit at the right price for us. When it came to the installation, they came on time, fitted the unit and got it up and running with the minimum of fuss. We are extremely happy with the service Earthwise provided and would recommend them to anyone looking for a similar product.

    G. Orriss – MVHR supply & install
  • Ben and his team did a total refurbishment of my house and also extended it at the front and back. A very important part of my project was to achieve a very energy efficient house. Ben is an expert in this area and fully understands the need for airtightness and the insulation requirements. He also has the skills to install the heat recovery ventilation system (MVHR). We are now living in a very warm house with minimal heating bills. Ben has a highly skilled team who take pride in doing a quality job. Earthwise Construction is an excellent building company that you can trust. I would highly recommend them.

    Ken Mills – Retrofit of 1960s house
  • In the world of house builds and retrofits, it can be hard to find a contractor, full stop! But especially hard to find one without compromise: quality usually comes at cost, and low budget usually comes with high risk. Ben, and Earthwise under his direction, were not a compromise in any way. They delivered that most unlikely of outcomes: a bespoke house build under budget! I have recommended them on numerous occasions and will continue to do so, gladly. We feel very lucky to have found and worked with them on our project.

    Nick Easton & Ellie Sans – New build AECB Silver timber frame house
  • Sustainable construction is Ben’s forte and he does it well. He is a good problem solver with attention to detail where necessary and a sound grasp of the modern building techniques required to construct the sort of places that we’ll all need to be living in if we’re serious about tackling climate change.

    On site, Ben and his team were reliable and delivered a high quality of work. We could see that Ben’s calm approach was key to coordinating other contractors and maintaining a motivated workforce. I would highly recommend Earthwise Construction to others.

    Alan Davies – Retrofit and extension of Victorian terraced house
  • I would have no hesitation in recommending Earthwise Construction, they were a real pleasure to work with. It was pleasing to see the attention to fine detail of the building’s design (e.g. ensuring that it achieved a good level or air-tightness) and in the constant consciousness that the most sustainable materials were used and that material waste was minimised. They have successfully delivered a group of fantastic sustainable apartments that are going to be wonderful, low-cost homes for co-op members for years to come.

    Trevor Houghton – New build for Somewhere Cooperative Housing Association
  • It was a pleasure working with Earthwise Construction, we couldn’t have hoped to have a nicer group of people in our home. Our house uses Passivhaus principles to create a very low energy home from a fabric point of view. Now, four years on, the energy performance of our home is better than predicted, which is testament to the skill of Earthwise Construction in executing many difficult details and achieving an excellent airtightness test value of 0.81 on a complex refurbishment project. I would have no hesitation in recommending Earthwise Construction to others and have already done so on many occasions.

    James Walker – Retrofit & extension of 1930s industrial unit
  • Earthwise did a great job building a new studio space at the city farm. Ben and team were all friendly, considerate and accommodating. The quality of the finish is great with very neat detailing to the timber work.

    Windmill Hill City Farm – Office space
  • Earthwise Construction fitted my MVHR unit. It wasn’t an easy job but John made it look easy! He has brought an enormous amount of joy to a very stressful self build. He was professional, helpful, prompt, tidy and a pleasure to have on site. What a super star you have in the company. Thanks Ben for all your help.
