Highgate sits on high ground and that reaches into almost every job here. Houses around the Village and the streets falling away towards Waterlow Park and the cemetery are exposed to weather at their upper storeys, plots step down rather than running level, and gardens are held up by old brick retaining walls never designed for what is now behind them. The stock is largely pre-war and generously built. On VOA figures, most homes are flats, where the freeholder's licence comes first. After that, what decides the order in N6 is the roof, the ground, and whether a lorry can reach the front.
Of the 10,090 homes the valuation list records in Highgate, 47% were built before 1919, 24% between the wars and 28% since 1945; 69% are flats and 31% are houses. VOA Council Tax stock of properties, March 2025, for Highgate West, Highgate East and Highgate Wood. Counts rounded by the VOA.
Sloping ground, retaining walls and drainage come before building out
Extending a house on a plot that falls away is a groundworks job before it is an extension. Foundations step down the slope, excavation depths change across the footprint, and the engineer determines what is required from what the trial holes show rather than from a standard detail. Old garden retaining walls often turn out to be single skin brick with no drainage behind them, which is fine until you load the ground above or excavate in front. Where a new structure retains ground, it is designed as a retaining structure and built to that design.
Water moves downhill and so does everyone else's. Surface run-off from higher ground, collapsed drainage runs and soakaways that stopped working years ago all show up as damp at the bottom of a sloping plot. Resolve the drainage while the ground is open, because doing it afterwards means digging the same trenches twice. Access is the other constraint on the steep, narrow streets near the Village, where large vehicles cannot turn, scaffold needs stepped bases and deliveries are planned in sizes that will actually arrive. Neighbours are warned before any delivery that will block a narrow street for a while.

FAQ
Building work in Highgate: common questions
Does a sloping garden make an extension more difficult?
It adds groundwork rather than difficulty. Foundations are stepped, retaining is designed wherever ground is held back, and the drainage has to work with the fall instead of against it. The engineer sets depths after trial holes, and the open excavation is inspected before concrete goes in. Nothing about a slope prevents a good extension, it simply means more of the effort sits below the finished floor level.
Should the roof be dealt with before the interior?
Yes, almost always. There is little point plastering, wiring and decorating beneath a covering that still lets water through, and roof work carried out afterwards means scaffolding, disruption and risk to finishes only just completed. Roof, rainwater goods and any high level pointing come first, then structural work inside such as RSJ installation, then services, then finishes.
