Extensions- 13 Dec 2021
GARDEN ROOM - instead of extending the conservatory, we decided to build a garden room instead. Ionut took the lead with the design and structure, and I’m over the moon with the results. A great experience from start to finish - Ionut was a pleasure to deal - friendly, professional and courteous. Would highly recommend.

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.
