Sustainable building examples
Dewdown Lodge, Somerset

Re-build of an existing lodge in Somerset to create a stylish and energy efficient family home.

​It is common for a client to approach us after the planning process, after a difficult time gaining approval and feeling disinclined to re-visit the design in any significant way.

But experienced as we are in both design and construction, we will often spot a number of ways that a building design could be changed to improve its look, performance, buildability – or all three as was the case at Dewdown Lodge.

The clients could see the benefit of the changes we proposed, and though a few weeks may have been added to the program, the outcome was all the better for it.

The original lodge building had some aesthetic appeal but limited space – especially on the first floor due to the low roof and small dormer windows.

It was situated well on the plot and was of sound structure, so the premise was always to retain as much of the ground floor as possible while vastly improving the energy efficiency, remodelling the interior spaces and raising/rotating the roof.

The result is a generous, stylish, efficient and comfortable 4 bed family home.

We would recommend Greenheart without reservation and have already to countless people. The quality of the design and the work has been outstanding. Not only that, but the team were exceptional. To have achieved what we did in a little over a year is quite honestly remarkable.

We just want to say thank you. We know this would not have been the easiest build for you nor one that you would normally do (not a new build). But in a way, this is the most sustainable of all – re-imagining an existing building using almost entirely natural materials and going from an EPC rating of E to a B (almost an A). The team were lovely, worked incredibly hard and took real pride in what they did. It shows.
