In Richmond Hill and Ham (TW10) the split is 35% flats to 65% houses over 2,156 households, and the stock is Georgian and early Victorian.
The owner-occupier-led mix here (58% owned, 15% privately rented) means a TW10 diary swings between short-notice tenancy deadlines and appointments set a fortnight out.
Richmond Hill and Ham substrates run to some of it dry-lined during a later refurbishment — and solid London stock brick, the pattern behind 2,156 households inside the TW10 neighbourhood. Nothing is drilled until the wall has been sounded, because Richmond Hill and Ham gives us fixings landing in soft lime mortar joints instead of the brick body, which is what a 35% flat share across the ONS neighbourhood covering Richmond Hill and Ham actually produces is the mistake that costs a TW10 customer twice.
Richmond Hill and Ham is outside the Congestion Charge zone but inside ULEZ; our vehicles are compliant, so nothing is added for it. What shapes the job more is the neighbourhood itself — the protected view from the hill, Ham House and the riverside meadows below — which is why a TW10 quote is not a Richmond upon Thames average.
On access, extremely steep hill, narrow riverside lanes at Ham and conservation-area limits — one reason standard crews are two people with a 3.5-tonne Luton; bigger clears run two vans or return the same day rather than overfilling.
