Flat conversion drawings in Haringey, from £1,095 fixed

Haringey's DM16 allows a house to be converted into flats only above 120 square metres of original floor area, and in a Family Housing Protection Zone only if no family-sized home is lost. We measure first, then draw layouts that stack bedrooms over bedrooms and meet the space standards.

What Haringey Council asks of a flat conversion

From the council's Conversion of houses to flats (Development Management DPD Policy DM16) (adopted current council planning advice, read 25 October 2026).

  • Haringey's policy DM16 permits the subdivision of larger homes into smaller self-contained flats where the gross original internal floor space of the dwelling is greater than 120 square metres. (source, checked 25 October 2026)
  • Within Family Housing Protection Zones, shown on the planning policy map, there must also be no net loss of family-sized units, which Haringey defines as three bedrooms or more. (source, checked 25 October 2026)
  • Flats must meet the nationally described space standards and the Mayor of London's Housing SPG, with room layouts that stack bedrooms above bedrooms and living areas above living areas to limit noise between homes. (source, checked 25 October 2026)
  • External changes to the building, garden or forecourt must comply with policies DM12 and DM16 and not harm the character of the area, and the scheme must give satisfactory amenity space, privacy, daylight, parking and access, and refuse storage. (source, checked 25 October 2026)
  • Every residential conversion should be supported by a car parking survey showing residual supply for the need created, using the Lambeth parking survey methodology. (source, checked 25 October 2026)

What Haringey flat conversion drawings have to show

In Haringey the first drawing is a measurement: the gross original internal floor area, taken from the survey, because DM16 only opens the door above 120 square metres. Where the house is in a Family Housing Protection Zone, the proposed plans show the family-sized unit of three or more bedrooms that the policy requires to be kept, labelled by bedroom count.

Layouts are drawn with the stacking in mind, so a first-floor bedroom never sits over a ground-floor living room if a swap fixes it. The set includes a refuse and cycle storage plan, the amenity space allocation for each flat and the daylight and privacy points Haringey lists, and the parking survey follows the Lambeth method the council names.

Answers

Haringey flat conversion questions

How big must a house be to convert into flats in Haringey?
Haringey's policy DM16 permits subdividing a home into smaller self-contained flats where the gross original internal floor space is greater than 120 square metres. We take that figure from your measured survey, so we know before any layouts are drawn whether the house qualifies.
What is a Family Housing Protection Zone in Haringey?
It is an area on Haringey's planning policy map where a conversion must also result in no net loss of family-sized units, which the council defines as three bedrooms or more. If your house is inside one, the scheme has to keep a three-bedroom home within the building.
Does Haringey need a parking survey for a flat conversion?
Yes. Haringey says all residential conversions should be supported by a car parking survey showing there is residual parking supply to meet the need the conversion creates, and the survey should use the Lambeth parking survey methodology. We tell you early so the survey can be booked while the drawings are prepared.
