What We Do

Home Extensions

No-one wants to feel over-crowded and cramped, as families grow in size space can become a necessity, everyone needs an area to call their own. An office or study area, a larger kitchen, an extra bedroom for visitors, even a particular spot for reading or crafts.

Whatever space you want, Applewood construction services will help you to produce an additional space that complements your home.


We offer a wide range of services & property maintenance with our team of experts who respond very accurately to our customers’ requirements.

Every customer and every project add to our working experience. A perfect finish is among the primary set of services that turn home to its perfection.

New Builds

We pride ourselves on being accessible throughout your new build project and working closely with you to get your design perfect.

Loft Conversions

Are you looking to extend your living room? No space for an extension? Then think about moving upwards; a loft conversion will add another floor to your home, and that much-needed space.

Looking for a team of professionals to handle this for you? We at Applewood Build offers a complete package to make sure your conversion meets all your expectations.

Recent Testimonial 

We chose Applewood thanks to recommendations from a number of local friends. Our two-storey extension was completed on time and on budget thanks to Martyn's fantastic organisational skills and the care taken by his team. They were a pleasure to work with, in fact we rather enjoyed the whole process and missed them after they left! And we couldn't be more delighted with the final result - should have done it years ago.
