After builders cleaning in Holland Park, W14

Of the homes with a recorded build date in the local Census area, 66.7% were built before 1900 and 15.8% from 1945 to 1972. Holland ward is 82.7% flats. The Holland Park conservation area was first designated in 1971 and extended in stages up to 1985, and the listed houses include Debenham House at Grade I and Leighton House and Aubrey House at Grade II*.

A conversion flat has its own pattern of dust. The front room keeps its original cornice and ceiling rose, a new partition splits what was one room into two, and the bathroom often sits where a dressing room used to be. Fresh plaster on those partitions is where most of the fine dust comes from, and it settles in the old mouldings next door. The crew dusts cornices, picture rails and the tops of doors first, then radiators, skirting and switches, and does the floors last. Furniture that stayed in the flat under sheets can be cleaned on the same visit; see cleaning a dusty sofa.

Whole houses are rarer: 12.4% of households live in a terraced house and 2.4% in a detached one. A 5-bed house after a refurbishment is usually 3 cleaners for 5 hours, £482 all in. On a house that size the crew grows and the day stays about the same length.

The Royal Borough gives no permits to visitors or businesses, so the crew's car goes in a space you provide, a pay-by-phone bay or a car park. Elsewhere in the borough pay-by-phone bays are free on Sundays; most of Holland ward is an exception, so a Sunday clean here is paid parking too. Tell the office the street when it rings and it will plan the parking with you.

West of the boundary, Shepherds Bush follows Hammersmith and Fulham's rules; south is Kensington High Street and north, across Holland Park Avenue, is Notting Hill. Council fees and waste rules for the rest of Kensington and Chelsea are on the borough page.
