Tyler, Ryan and their team completed our single storey rear extension. They were highly professional, good communication throughout and completed the build to a very high standard on time and budget. We are extremely happy and will be using them again for future projects. I would highly recommend them to anyone.

Extensions & New Builds
Adding Space and Value, Done Properly
An extension is one of the biggest investments you'll make in your home, so it needs to be planned and built right. Lindemann & Gregory design and build single and double-storey extensions, side-return and wrap-around extensions, and full new build homes and annexes across Buckinghamshire, Berkshire & Oxfordshire. Every project is handled by Tyler and Ryan directly, so you always know who's on site and who's accountable for the finish.
From groundworks and structural steelwork through to first fix, plastering and final decoration, we manage the entire build in-house wherever possible, bringing in trusted trades only where specialist work is needed. We also liaise with your architect and, where required, the local planning and building control team, so your project stays on track from initial design through to completion - with clear communication at every stage.
