Infill plots wanted in Sidcup
We are actively looking for infill plots in Sidcup and the surrounding area, with or without planning permission.
Infill plots fill a gap in an existing street. They are usually small, but because they sit within built-up areas the planning case can be good. We buy infill land across England and Wales, with or without consent.

Is your land in Sidcup the kind we want?
We look for infill plots across Sidcup and the surrounding villages, particularly where there is room for parking off the road. In Greater London, Sidcup sits about 11 miles south-east of central London; Bexley and Orpington are its nearest neighbours on our list.
- Side gardens with their own road frontage
- Corner plots within built-up areas
- Plots large enough for one or more homes with parking
- Land with or without an earlier planning history
Outer London, from Romford and Bexley to Uxbridge, Barnet, Croydon and Sutton, contains most of the capital's remaining land opportunities. Around the edge, the Metropolitan Green Belt and Metropolitan Open Land protect open space, and a small part of the Kent Downs National Landscape lies in the south-east. Sites usually come forward as small infill plots, garage courts, backland, former commercial buildings and occasional grey belt land on the urban fringe.
Before we make an offer in Sidcup
Character of the street
New homes need to suit the building line, height and spacing of the street.
Parking and access
A safe access and enough parking can decide small schemes.
Services
Connections for drainage, water and power need to be reachable.
In England, the revised National Planning Policy Framework published on 17 August 2026 replaced the old "tilted balance" with new settlement policies: development within a settlement should normally be approved unless the harm substantially outweighs the benefits, while land outside a settlement can gain support in defined circumstances.
Parts of Greater London are Green Belt, though not every town has any nearby. We check early whether a site is inside it and, if so, whether a grey belt or previously developed land case could apply.
We are based in Great Barr, Birmingham, around 115 miles from Sidcup, and we travel to see sites across England and Wales.

Questions owners in Sidcup ask
How wide does an infill plot need to be?
There is no fixed figure; it depends on the street. A plot that allows a home similar in width to its neighbours, with space to the sides, is a good start.
Will my neighbours be consulted?
Yes. The council consults neighbours on planning applications, and their comments are considered alongside policy.
Do you buy infill plots in Sidcup?
Yes. We buy infill plots in Sidcup and throughout Greater London, as well as elsewhere in England and Wales. Tell us where the land is and we will give you a free appraisal.
Which planning rules apply to land in Sidcup?
As Sidcup is in England, national policy comes from the National Planning Policy Framework, revised in August 2026. Local policies in the council's development plan also apply.
