In Finchley (N3) the split is 56% flats to 44% houses over 15,367 households, and the stock is inter-war.
The renter-heavy mix here (54% owned, 37% privately rented) means a N3 diary swings between short-notice tenancy deadlines and appointments set a fortnight out.
Finchley substrates run to dot-and-dab plasterboard over blockwork in N3, with metal stud partitions between rooms, and driveway parking on most streets; the north circular junctions congest at peak. Nothing is drilled until the wall has been sounded, because Finchley gives us short screws that grip only the board and slowly lever it off the dabs, which is what a 56% flat share across the ONS neighbourhood covering Finchley actually produces is the mistake that costs a N3 customer twice.
Finchley 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 — suburban centre of 1930s semis, synagogues and a long shopping road — which is why a N3 quote is not a Barnet average.
On access, driveway parking on most streets; the North Circular junctions congest at peak — one reason two crew and a Luton on a small office or shop unit; three to four crew with a 7.5-tonne vehicle on retail strip-outs, warehouses and racking removals.
