Building work in Kettering
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 Kettering
Our work splits into two connected halves.
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. We match materials and work within any conservation-area constraints rather than around them.
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.
Kettering & villages we cover
We cover Kettering and the surrounding villages including Barton Seagrave, Burton Latimer, Broughton, Geddington, Rothwell and Desborough.
Prices, planning and building control in Kettering

“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”
