"The team at Eco T.E.S have been nothing short of fantastic in all aspects of the support and help they have given us with our restoration based on Passive House principles of a Victorian terraced cottage in the Ottery St Mary Conservation Area. We knew the project would be a challenge but we didn’t understand the extent of the structural problems that existed in the building until we started stripping off the internal plaster and finishes. We discovered that previous works to remove the rear chimney breast has undermined the entire structure of the building. In the end we had no choice but to remove everything apart from the front facade and party walls. This left us with the challenge of how to re-build within the original footprint using the most environmentally friendly materials possible, whilst also aiming for passive house levels of insulation and airtightness. We were determined that the carbon footprint of the project should be as low as possible both for the future operation of the house but also the emissions involved in the manufacture of the materials used for the re-build. 

We approached a handful of timber frame and I-joist suppliers and with the exception of Eco T.E.S they all said either that what we wanted to do couldn’t be done in an existing building or that they were only interested in supplying frames for complete new builds. When I found Eco T.E.S’s details after researching the Steico Building System and gave them a call, they could not have been more helpful or enthusiastic. Not only did they believe in the project but thought that using Steico I-joists, LVL and wood fibre insulation products was the perfect solution for our project.

Working within an existing building footprint brings different challenges to a complete new-build and with Eco T.E.S’s help we were able to overcome them all. I cannot recommend the team at Eco T.E.S highly enough, it has been a pleasure to work with them and I look forward to working together again on future projects."
