We offer a comprehensive building service to handle your building work from start to finish. We can project manage your build and liase with the relevant authorities on your behalf, giving you peace of mind and reassurance that your project is in safe hands.

We value all our customers, from the smallest jobs to the largest, with no exclusivity towards clients or high prices. We can provide that much needed extension to your home or create the loft conversion you always wished for.

Why not give us a call today to talk through your plans for extra space? Or send us a mail via our contact page and we will give you a call back.


Even if your extension doesn’t need planning permission, there is no such thing as permitted development when it comes to Building Control. It really is not worth cutting corners in the design of your extension, or by not getting the necessary permissions. Mistakes can be costly to put right, or even downright dangerous.

APW Building Services offers a complete design and build service for your extension. We can work with you to design an extension that makes the most of your space, fits in with your existing home, looks great and also conforms to building regulations. Or work from existing plans, if you have already had these drawn up.

We will handle all the necessary paperwork and permissions, and arrange for building work to be signed off at the right times.

Garage & loft conversions

Loft conversions are an obvious way to add space to your home, but limited headroom can sometimes mean that there isn’t as much useable space as you would like. It can sometimes be tricky to find the space to add an access staircase too.

Garage conversions can be a surprisingly cost effective way to add the extra space you need. Many garages are  not used for much except additional storage, or as a utility room, as they are too small or awkward for parking a family car in. An added advantage of converting your garage is that it minimises the disruption of building work going on in your home.

We can advise on the most cost effective way to add extra space to your house. Contact APW Building Services for a free, no obligation, consultation.
