Loft conversions are an incredible addition to any home. Not only do they allow you to gain a huge amount of space, for some an entirely additional floor, but they allow you to do so without having to sacrifice that precious outdoor space so many in London love so much.

Attic constructions are an awesome way to add a bedroom, bathroom, office or even playroom as well as adding value to your home.

Despite the relatively little work in comparison to your average home extension that requires everything from footings and more before even a brick is laid, loft conversions are practically already there – they merely need to be shaped by the professionals – and that’s where we come in.

Here at Clapham Construction Service, we’ve become London’s go-to company for loft conversions, and for good reason too. We’re specialists not only when it comes to loft conversions, but more specifically loft conversions in London.

We’ve navigated London’s narrow streets and tough councils for a number of years, so many so that we’re confident in saying that we’re not only the best when it comes to our construction work, but we’re the best when it comes to planning and consent as well as overcoming the obstacles that this wonderful city can often throw our way. 

We understand however, that for some, that’s simply not enough, so here’s a rundown as to why you should choose Clapham Construction Service to complete your loft conversion.
