House extensions in Tunbridge Wells
Tunbridge Wells is a demanding place to build well, in the best sense. Its Victorian and Edwardian homes and its Wealden cottages were built with care, and an extension has to be worthy of them. That is the standard we work to.

Matched to your home
The extensions we build in and around Tunbridge Wells
- Side return extensions on the town's Victorian and Edwardian homes, turning narrow kitchens into wide, light family rooms.
- Rear extensions that open the back of the house to the garden.
- Wrap around extensions where the plot allows both.
- Double storey extensions that add a bedroom or bathroom above new ground floor space.
- Sympathetic extensions to cottages and period homes in the Weald, using tile hanging, weatherboarding, local sandstone and handmade brick so the addition belongs.
Planning & regulations
Planning permission in Tunbridge Wells
Tunbridge Wells has one of the richest heritage settings in Kent, and that shapes what you can build.
Your planning authority is Tunbridge Wells Borough Council. The borough has twenty-five conservation areas, including the Royal Tunbridge Wells town centre with its Pantiles and Victorian crescents, plus centres like Southborough and Cranbrook. More than seventy per cent of the borough lies within the High Weald National Landscape, the protected area formerly known as an Area of Outstanding Natural Beauty, and there is Green Belt to the north.
In plain terms, these protections lower the size of extension you can build under permitted development and raise the bar on design and materials. Listed buildings, of which the borough has many, need separate listed building consent.
None of this stops good projects going ahead. The council approves a high proportion of well designed applications. It just means the design has to be right and the application has to be handled properly, which is exactly what we do for you.
Building on Wealden ground: sand, clay and sloping sites
The ground around Tunbridge Wells is not the flat, uniform stuff builders prefer, and that is worth knowing before you dig.
Much of the area sits on Tunbridge Wells Sand, a sandstone that overlies Wadhurst Clay. Where the two meet, water often seeps out along spring lines, and the High Weald's steep, valleyed landscape means many gardens slope. A sloping site, a spring line or a change in ground between sand and clay all affect how foundations are designed, and sometimes call for a ground investigation before work starts.
This is the kind of detail that separates a build that lasts from one that gives trouble later. We plan the groundwork around the site you actually have.
Cost, in the open
What an extension costs in Tunbridge Wells
Cost comes down to size, specification, ground conditions and finish, and Tunbridge Wells adds a couple of local factors.
Protected settings can mean higher quality materials and more design work, and sloping or spring line sites can mean more groundwork. As a general South East guide, single storey extensions commonly run at a few thousand pounds per square metre, with double storey often better value per square metre. Use our cost calculator for an early estimate, and book a site visit for a real figure on your property.

Common questions
House extension questions in Tunbridge Wells, answered straight
The questions every Tunbridge Wells homeowner asks at the first site visit.
Anything else? Call 07920 731533 and you’ll speak to Jason Berry, not a call centre.
Often, yes. Much of the borough sits within conservation areas or the High Weald National Landscape, which reduce permitted development rights, and listed buildings need separate consent. It depends on your exact property, and we check it for you before you plan the work.
Yes. The protection means a smaller permitted development allowance and a higher design standard, not a ban on extending. Well designed schemes are regularly approved. We design with those requirements in mind from the start.
Yes. Tunbridge Wells is full of period property, and we extend and renovate it sympathetically, matching materials like tile hanging, weatherboarding and handmade brick, and handling listed building consent where it applies.
It depends on size, specification and ground conditions, and protected settings or sloping sites can add to it. As a rough guide, single storey extensions in this area commonly run at a few thousand pounds per square metre. A site visit gives you an accurate figure.
The area's mix of sandstone, clay and sloping, spring line sites affects how foundations are designed. Understanding it before we start avoids problems later, which is why we plan the groundwork around your specific site.
