Building work in Corby
Whether you are improving the front of the house, opening up the kitchen or reworking the whole plot, we take it from first visit to finished.
Everything we build and lay in Corby
Across Corby and its villages we are regularly asked to handle a whole property at once — extend the house, then sort the driveway and garden around it.
Building work. Single and double storey extensions, kitchen and rear-return extensions, garage conversions and porches — all built to Building Regulations and inspected by Local Authority Building Control.
Driveways, patios and gardens. Resin bound and block paved driveways, porcelain and natural stone patios, full landscaping and garden transformations, fencing and sleeper walls. Permeable surfacing as standard, so drainage rules are met without a second thought.
On Corby's newer estates we often handle both the extension and the garden that surrounds it.
Corby & villages we cover
We cover Corby and the surrounding villages including Weldon, Gretton, Cottingham, Middleton, Rockingham and Stanion.

“These guys fitted our job in at short notice, did a great job despite the harsh weather. We had great communication throughout the project as it was not quite as simple as we first thought. We definitely recommend them and will be using them for future projects”
