We used Kirkwood for our House Extension in Billericay, Essex. The project was managed by Jamie at Kirkwood and he took care of every step in the process. Kirkwood took care of the planning with their inhouse Architect, suggested a 3rd Party Building Control and right through to the build of the extension. This wasnt just an extension but a complete internal remodel. We are happy to recommend Kirkwood and in fact they have just completed a similar project at our neighbours house following our works.

A very professional company who listened to our thoughts and plans for our driveway and brought them to life. We have recommended them to friends who have also in turn recommended them to others, so their work speaks for itself. We are looking forward to Kirkwood transforming our back garden later this year.

Kirkwoods did a fantastic job if our garden after another company left us in the middle of the job with a building site for a garden. Jamie chatted through my plan with me and advised me regarding materials and the design. Their execution was exemplary as was their work ethic and reliability. I would not hesitate to recommend Kirkwoods to anyone.

We’ve used Jamie and his kirkwood team for various construction work over the years. We have also seen them first hand on what they can offer their clients. Professional, punctual and quality of workmanship is second to none. We look forward to either working alongside them and when we need them using there services once again to help us with our ongoing projects.
