I've just (almost) completed a large extension to my house in Harrogate. I just wanted to recommend our builder, as it can be so hard to find someone reliable and good at their job.
I used Lee Walker Building and Joinery. They were recommended to me by a neighbour and I can't praise them highly enough. A really pleasant team, excellent quality of work and a pleasure to have on site. Lee acted as project manager and took all the headache of planning away from me.
