Project management for new builds, extensions and more

We offer a wide range of bespoke building services, including planning and design. You can trust us to make your perfect space into a stunningly finished reality.


Why move away when you can make your beloved home work for you? Our team expands to the rear or side and can even build upwards, managing multi-storey projects to create spacious living areas.


New property builds can prove hugely complex, and you need someone who can schedule the various phases in-house. At N Mayes Bespoke Building, we create custom homes with all services undertaken.


Would you like to make the most of your garden? Our team can build a garden room towards the end of your space, so you can work, relax or take up creative hobbies in a unique environment.


If you have a disused garage, consider what it could become with some professional care. We provide a full conversion service, turning cold and forgotten garages into beautiful rooms for modern living.
