Building work in Totteridge: area guide
Every trade under one contract across Totteridge and N20. Structural work, extensions, kitchens and bathrooms, building control handled for you.
This is our area guide to building work in Totteridge (N20, Barnet): the housing, the council rules that apply (Barnet Council for planning) and every service we offer here. For whole-house refurbishment go to Home renovation in Totteridge.
Totteridge is large houses on generous plots, and the work reflects that. Around Totteridge Village, Totteridge Green and out towards Darlands Lake these are substantial detached homes, most of them built between the wars or since, where the job is usually a home renovation or a significant structural alteration rather than a single room. Plots are wide, mature planting is part of the setting, and some properties are protected. We establish the consent position before design work begins and appoint the structural engineer for anything that carries load.
About 3,700 homes are listed for Totteridge, and the mix is 88% houses to 12% flats, with 60% built after 1945, 33% in 1919 to 1939 and 8% earlier. VOA Council Tax stock of properties, March 2025, for Totteridge & Barnet Gate. Counts rounded by the VOA.
Consents come before drawings and before walls
On a house of this kind the first question is what may be altered, not what you would like altered. Where a property carries statutory protection, consent is required for changes affecting its character, which can extend to internal walls, joinery and plasterwork as well as elevations, so a load-bearing wall removal waits on it.
Listed building consent, where it applies, is separate from planning permission and from building regulations approval, and satisfying one does not discharge the others. Establishing which apply at the outset prevents a design that cannot be approved and drawings that go nowhere.
Ground, trees and new foundations on a Totteridge addition
Mature trees are much of what these plots are valued for, and they shape every new foundation, the first question on a house extension job. On clay ground a tree draws moisture from the soil and the ground moves seasonally with it. The engineer sets foundation depth with species and distance in mind rather than a standard figure.
Felling a large tree is not the safe default, because ground kept dry for decades can swell once it has gone, lifting what sits on it. Trees may also be protected, so consent is checked before any method depends on removal. The engineer and an arboriculturist weigh the options.
Running a long programme on a large house, trade by trade
Work across several floors involves rewiring, replumbing, heating, structural openings, joinery and decoration, each trade following the one before, and the openings are an RSJ job that lands early. The programme is set at the outset so trades follow rather than wait, and long lead items such as joinery and windows are ordered once the design is fixed.
Where consents are involved they run to their own timetables and start when the scope is agreed, so they proceed alongside procurement rather than after it. A programme built on the building work alone will slip on the paperwork.

FAQ
Building work in Totteridge: common questions
Does work inside a Totteridge house need consent?
Where the property carries statutory protection, it can, and the protection extends to the interior. Alterations affecting character, including removing internal walls or altering joinery and plasterwork, may require listed building consent. That is separate from planning permission and from building regulations. The position is established before a design is developed rather than afterwards.
Can a large Totteridge house be extended?
Frequently, and the plot is rarely what limits it. What governs the design more often is the effect on the existing building and, where the property is protected, what consent will allow. Foundation depth is set by the ground conditions and any nearby trees. A wide shallow addition usually sits better against a substantial house than a deep narrow one.
Will removing a tree solve movement at a Totteridge property?
Not reliably, and it can cause a different problem. Ground that a tree has kept dry for years may swell once it is gone, which lifts foundations rather than settling them. The cause of any movement is diagnosed first, because drainage faults and failed lintels account for a great deal of what gets attributed to trees.
How long does a large house project take here?
Months rather than weeks, and the consents often set the date rather than the trades. Rewiring, replumbing, heating, structural work, joinery and decoration follow one another in sequence across a large house. Long lead items are ordered when the design is fixed so they are not discovered on the critical path later.
