Latest review:
We recently completed a large renovation which included extending our kitchen at the rear of the property, changing levels in the garden and converting our loft with an additional bedroom and en-suite. Ben, Steve and the rest of their team were amazing throughout. We had difficulty moving out of the property as our short term let fell through but the team worked tirelessly to enable us to ‘live in’ whilst much of the build was going on (which I know wasn’t ideal!) I highly recommend Integrated Homes as Ben and Steve were so knowledgeable, considerate and professional in their work.

Extensions- 4 Nov 2023
Overall me and my husband are very satisfied with the workmanship and with the final result of our my fake cladded garage door with the new aluminium framed window. The original garage was converted into a habitable room 7 years ago with only a rooflight to bring light into the room, which is now my husband's office and this new window will make a lot of difference therefore we are very happy with the finished work. The work was done very quickly, the builders turned up on time and they were very efficient and helpful, they took particular care when installing the composite slatted panels to the marine plywood. The main contractor Pawel Speiwak also came on site to inspect the works during construction. The quote was also very competetive, a good value for money. I would definetely use them again for any future work in my house and recommend them to other people.
