Happy Clients


We were having some issues with our previous construction company when one of my friends recommended LSA Construction. Ours was a kitchen extension project and we wanted more indoor space to entertain our guests. We talked to their team and told them what we were looking for. They were really friendly and considerate.

Needless to say, our kitchen turned out to be exactly like we wanted and we have never regretted our decision since!

Oliver and Nancy Adams

This was my first experience with LSA Construction. I was a bit worried, even with their great reputation. But once I met their team and saw what they can do, I never doubted their skills!

Now I am going to stick to LSA construction for all my refurbishing projects!

Henry Johnson

We are a big family and it seems that we are always short on living space. So we decided to convert our loft into a bedroom for our daughter. Being a teenager, she had some really big (and unpractical) ideas for her bedroom. But we had such a great experience with LSA! They handled our teenager really well and now she loves her bedroom so much she rarely comes out of there… lol
