Having chosen to use them based on reviews and recommendations we had found on this site and others while planning our kitchen extension, I thought it was only right to post my own now that ours is pretty much finished...
We used Plusrooms to build a side return and kitchen extension to replace an existing conservatory. They are a very professional company and guided us through the process effectively. We had some issues around planning permission and the depth of foundations due to nearby trees, but Plusrooms were proactive in helping us deal with these problems and found solutions that limited the additional costs accrued.
The builld phase of the work was carried out extremely well, with an excellent team who finished almost two weeks ahead of schedule. We have experienced a slightly slower pace of progress with the finishing team, but we are hoping the project will be fully finished soon.
