Private drives, unadopted roads and adoption.
Whether your new road should be adopted or stay private, how many homes a private drive can serve, and what the council’s adoption standards mean for the layout.
Also known as: shared private drive how many houses, unadopted road, private road development, adoptable road standards, Section 38 adoption, estate road adoption
What’s included.
Councils usually limit how many homes can be served from a private drive, often around five, though it varies. Beyond that they expect an adoptable road built to their standards under a Section 38 agreement. Unadopted roads need a long-term management arrangement.
- Private drive limits under local guidance
- Adoptable road widths, radii and gradients
- Turning heads and visibility
- Footways and service strips
- Section 38 agreement process
- Management company arrangements for private roads
Straightforward, proportionate, agreed early.
Decide early
Adopted or private affects the layout, costs and future maintenance, so it is best decided at sketch stage.
Local standards
We apply the council’s own design guide, which varies a lot between authorities.
Long-term view
Private roads need a management plan buyers and lenders will accept.
Questions we get asked
How many houses can share a private drive?
It varies by council, often around five. We check the local design guide.
Do new roads have to be adopted?
Not always. Private roads are possible but need a management arrangement, and some councils resist them on larger schemes.
What is a Section 38 agreement?
An agreement under the Highways Act for the council to adopt a new road once it is built to its standards.
