In Coulsdon (CR5) the split is 22% flats to 78% houses over 6,754 households, and the stock is inter-war.
Because 12% of Coulsdon is privately rented and 14% socially rented, a lot of CR5 work is agreed with a landlord or managing agent rather than the person opening the door.
Coulsdon substrates run to solid London stock brick; locally that also means some of it dry-lined during a later refurbishment, which is why London Borough of Croydon kerb rules get settled before the van is loaded. Nothing is drilled until the wall has been sounded, because fixings landing in soft lime mortar joints instead of the brick body, as the Coulsdon stock goes, which is what a 22% flat share across the ONS neighbourhood covering Coulsdon actually produces is the mistake that costs a CR5 customer twice.
Coulsdon 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 — downland village on the North Downs edge, with Farthing Downs above the town — which is why a CR5 quote is not a Croydon average.
Steep downland roads, easy driveway parking and a narrow high street. Nearest station is Coulsdon South (Southern), and one cleaner for a flat; two for a house, so the property is finished in one visit rather than split across a day.
