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- 3 Oct 2025
Job was to convert WC in outbuilding into a full bathroom, do walls and ceiling in outbuilding to convert into an office space. Price was agreed with things planned, still with some issues towards later part of job, It worked out in the end. Overall I am giving 3-4 stars as quality of work is good. Just need to have things written down with him, and a thorough discussion on plan before commencing work and agree on payment plan. suggested to keep 20% to be paid at completion.
