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.
