Planning Permission in Northamptonshire
Planning permission in Northamptonshire is administered by West Northamptonshire Council for the western and central parts of the county and by North Northamptonshire Council for the eastern and northern areas. Both councils were established in April 2021 following the abolition of Northamptonshire County Council and the seven former district and borough councils.
West Northamptonshire Council's planning pages are developing the council's new planning service following the 2021 reorganisation. The council is currently applying a composite of the former district councils' adopted policies - from South Northamptonshire, Daventry District and the Borough of Northampton - while its new West Northamptonshire Local Plan is being prepared. Self-builders in the West Northamptonshire area should contact the council's planning service to confirm the applicable policies for their specific location.
North Northamptonshire Council similarly operates under a composite of the former East Northamptonshire, Kettering, Corby and Wellingborough Local Plan policies while its new North Northamptonshire Local Plan is prepared. The council's planning pages provide access to its planning portal, validation requirements and pre-application advice service.
Community Infrastructure Levy arrangements in Northamptonshire are in transition following the 2021 reorganisation. Self-builders should confirm the current CIL position with the relevant unitary authority before committing to a site. Where CIL is charged, the self-build exemption is available for qualifying applicants who intend to occupy the completed home as their principal residence for at least three years.
Design expectations across Northamptonshire reflect the county's ironstone and limestone vernacular. Both unitary authorities expect self-build proposals to demonstrate an understanding of local building traditions, including the use of local stone (Northamptonshire ironstone in the north and Northamptonshire limestone in the south) for principal elevations, appropriate roofing materials such as Collyweston slate or Welsh slate, and building forms that respond to the rolling agricultural landscape.
The Nene Valley flood risk zone - extending across large areas of North Northamptonshire - requires detailed flood risk assessment for all self-build proposals within Flood Zone 2 or 3. The Environment Agency and the Nene Internal Drainage Board should be consulted on drainage proposals. Sustainable drainage systems are expected for all new residential development across the county.
Heritage impact assessments are required for proposals near listed buildings or within the county's many conservation areas. Northamptonshire's historic market towns and estate villages contain significant concentrations of listed buildings, and planning officers engage Historic England in the assessment of applications that may affect designated heritage assets.

Building your own home is the boldest financial move most people ever make. It's also the riskiest - if you're doing it without proper support.
80% of self-builders overspend by 25-30%. Not because they made bad decisions. Because they made complex decisions alone, without the right information, at the wrong moment.
