Kitchen Extension Cost in Camden Town: 2026 Price Guide

Ask a local builder what the most common job in Camden Town is, and a rear kitchen extension is usually near the top of the list - understandable given a mix of Georgian and Victorian terraces, converted industrial buildings from the area's canal-side trading past, and the busy streets around Camden Market across much of the area. Most homeowners are chasing the same thing: a proper kitchen-diner instead of a cramped galley kitchen.

Typical costs

• Small extension (up to 15m²): roughly £30,000-£45,000
• Medium extension (15-25m²): roughly £45,000-£70,000
• Larger or wraparound extension (25m²+): £70,000 upwards

None of these figures include the kitchen itself beyond a standard fit-out, so a higher-spec kitchen, bifold or sliding doors, a roof lantern and underfloor heating are all worth budgeting for separately on top.

What affects the price locally

The single biggest cost variable for a kitchen extension in Camden Town tends to be access rather than the extension itself - narrow terraced streets with no side passage mean materials and spoil go through the house, which shows up in the price. On top of that, the Camden Town conservation area, one of over 40 across the borough covering roughly half of Camden often means closer attention to matching brick, roofline and windows, adding cost even where planning permission itself isn't required.

Foundations are the other variable: older Victorian and Edwardian houses near Camden Market and Regent's Canal were often built on shallow footings, so a structural engineer may specify deeper or more extensive foundations than a newer property would need.

Do you need planning permission?

Permitted development covers a lot of single-storey rear extensions, but not without limits, and those limits bite harder on terraced and semi-detached houses than detached ones. Inside Camden Town's conservation areas, expect those rights to be trimmed back further still - check with the London Borough of Camden's planning department, or a builder who already works locally, before finalising a design.
