All works are quality controlled and we liaise with building control on your behalf and assuring our clients that all works are carried out to building regulations.

Single Storey Extension

A single-storey extension can add a kitchen or additional living space to your home, increasing the value of your property. Extending your existing kitchen into the side return can create a stunning new kitchen/living area and will be much admired by friends and family. In some circumstances, a ground floor extension can be built without planning permission. Please call us for free advice on your options.

Double Storey Extension

A double-storey extension can add extra bedrooms with en-suite facilities to your property. If you are not sure what can be done, we can advise you.

Roof Top Extension

A rooftop extension can turn an existing three-bedroom house into a five-bedroom house! Furthermore, the value-added to your property will by far exceed the cost of carrying out the works.

House Extensions
