Astracot Datchet

We did this project in 2005. Astracot is a Grade II listed house in Datchet Village. We faced lot of challenges on this project because this house was over 300 years old. Then main house is almost a meter lower than the main road. We had to keep the neighbours and local residents happy who had great interest in this house. Astracot used to be a coffee house and we found this picture while we were demolishing one of the walls.

Replicated Windows

If your residence is in a conservation area and you want to change the windows then you must have them replicated to the exact same specifications and design for them to pass building regulations standards. We can replicate windows in any material which will pass all of your local building control's relevant tests and inspection. Theses pictures are of a recent replication project in London depicting the the windows before and after the refit.
