House extensions in Tunbridge Wells
If you want more room on the ground floor of a Tunbridge Wells house, the usual answers are a rear extension, a side return or a combination of the two, most often to make a bigger kitchen that opens onto the garden. We are carpenters, joiners and builders working from a workshop in Biddenden, and we plan, price and build these projects from the first site visit to the last coat of paint.
The visit is free, and you get a written quote that sets out what is included before you commit to anything.
Ground floor and kitchen extensions
Across the borough, the 2021 Census counted 27.2% of homes as detached, 30.3% as semi-detached and 17.4% as terraced. Those three shapes lead to different extensions. A terrace usually has a narrow strip beside the back addition, which is where a side return earns its keep: it widens a cramped galley kitchen into a room you can put a table in. A semi often has the width for a full rear extension across the back. A detached house may allow an addition to the side as well as the rear.
Most of the kitchen extensions we are asked about are about light and flow as much as floor area. Taking out part of the rear wall and carrying the load on a new beam lets the old and new rooms read as one space, and roof glazing over the deepest part keeps the middle of the plan from going dark. Where a room sits on a slope or the garden is lower than the house, the floor level and the step down to the patio are settled at the design stage rather than on the day.
Enquiries reach us from all over the town, including High Brooms, Hawkenbury, Rusthall, Sherwood, Southborough and Pembury. Each has its own run of house types, from Victorian streets to post-war estates, and the design starts from the house in front of us rather than a standard plan.
Extending a period or conservation-area home
A large part of the town is protected. The Pantiles, Mount Sion, Calverley Park, Camden Park and Molyneux Park are each designated, and the centre holds a large number of listed buildings. Mount Pleasant and Calverley were developed as estates in the early 19th century, Calverley by Decimus Burton, and they set a high bar for anything added to them, so the brick, the roof covering and the proportions of new openings all need to sit well against the original house.
Materials have a local story too. High Weald sandstone was quarried at Langton Green for house building, and on an older house the stone, brick and tile already on the walls are the best guide to what a new addition should be built from. Where an exact match is not available, a deliberately quieter extension that does not compete with the old elevation is often the better route.
Inside, period homes bring their own jobs: skirtings, architraves, doors and cornices that need to run on into the new room. Our carpenters and joiners make that work in the Biddenden workshop so the join between old and new is hard to spot.
Planning and building control in Tunbridge Wells
The planning authority is Tunbridge Wells Borough Council. Royal since 1909 and sitting at the northern edge of the High Weald, the town lies in the setting of the High Weald AONB and the Metropolitan Green Belt, and both can affect how much a scheme on the edge of town is allowed to grow.
Some single storey rear extensions are permitted development, but the allowance does not reach a listed building and is tighter in a conservation area. Whichever route applies, building regulations still do: foundations, the beam over a widened opening, insulation and drainage are all inspected by building control. We confirm the likely planning route at the site visit and prepare the drawings for an application where one is needed.
For typical budgets, see our guides to single storey extension costs and kitchen extension costs.
How we run an extension
The work is carried out by our own carpenters and joiners, with specialist trades we work with regularly for the electrics, plumbing, plastering and glazing. One team is responsible for the programme, so the groundworks, the frame, the first fix and the finishes follow each other in the right order.
Everything is set out in a written quote before work starts, so you know what is included. If you want to see the wider range of what we build, visit our house extensions page or the Tunbridge Wells area page, or contact us to book a visit.
House extensions in Tunbridge Wells: questions
Do I need planning permission for a ground floor extension in Tunbridge Wells?
Not always. Some single storey rear extensions fall under permitted development, but that does not apply to a listed building and is more limited in a conservation area. Tunbridge Wells Borough Council decides; we check the likely route at the site visit.
Is a side return worth it on a Tunbridge Wells terrace?
Often, yes. The side strip beside a back addition is usually wasted space, and building over it can turn a narrow kitchen into a room wide enough for a table.
Can a new extension match a sandstone or brick period house?
We start from the materials already on the house. Where a close match is not available, a simpler extension that does not compete with the original is often the better choice.
