A great company that sticks to the plan. No surprises

We were really impressed with build dec construction from the start. We were recommended an architect for the plans who was excellent. Once the work started they were there every day as arranged and every thing fell into place. We were particularly impressed with how aware they were of the impact that certain stages would have on our routines. One great point was that they tidied up as much as they could each day. skips and deliveries came and went as planned. Different tradesmen started there faze in the works on time and apart from a couple of days disrupted by the weather all went to plan. I would definitely recommend build-dec

Brilliant job, we love the new rooms and layout.

Perry and his team constructed our side, rear and first floor extension last year.
Having never done any major work like this before we were nervous but Perry held our hands the whole way. He stuck to the fixed quote he gave us, we only spent more where we went for higher spec on tiles and bath suite etc. We got on well with all the guys and found them trustworthy and very accommodating as we were unable to move out for the build.
Perry got the right specialist tradesmen for each part of the work, payments were nicely spaced out through stages of the project and he is quick to sort any snagging issues.
All in all we had a really good experience, have a great standard of finish and love our new space.

Professionals who delivered quality on their estimates.

We have used these folk twice now. They are builders who take pride in doing the job right. While for larger jobs, such as an extension, they don’t do everything themselves, they do know reliable local tradesmen for specific skills they don’t have. Time to complete the jobs was what they said it would be in the estimates. Likewise the price was as expected, with the few variables flagged up in advance and explained and accounted for later. In short, a credit to their profession.
