Plan your extension and renovation in Newbury
Extra floor space, a new layout, or both?
Before asking for a quote, separate the space you want to add from the rooms you want to change. A rear extension might provide a larger kitchen and dining room, while remodelling could change how the existing lounge, hallway or utility connects to it. Describe both parts so the estimate covers the whole project you have in mind.
For a kitchen extension in Newbury, note where you want cooking, dining and storage, and which fittings you want to keep or replace. Our renovation service includes kitchen and bathroom coordination; our carpentry service covers doors, stairs and finishing details. Include these in the extension brief so the building work and finishing can be discussed together.
Look at the structural stages as well as the finish
Our Berkshire Rear Extension — Steel & Masonry project documents a full-width rear extension to a two-storey red-brick home. The gallery shows steel goalposts and beams, beam-and-block flooring, masonry and timber roof work. It gives you a view of the structural stages that sit behind the finished living space.
The Vaulted Kitchen Extension gallery provides a different reference, with roof detailing, underfloor heating and the fitted kitchen. Together the galleries help you discuss the structure, heating and finish you want. For your own property, ask how opening-up work, weatherproofing, services and final finishes will be sequenced, and discuss delivery access and use of existing rooms during the build.
Define the scope for your Newbury estimate
- Your Newbury address, photos and any drawings of the proposed work.
- New space to be built, listed separately from alterations to existing rooms.
- Kitchen, heating, flooring and joinery changes you want included in the estimate.
- Access constraints, whether the home will be occupied, your budget and target timescale.
