Dartford's position at the London end of Kent, next to the Dartford Crossing, sits alongside one of the largest strategic housing developments in the South East: Ebbsfleet Garden City, centred on Ebbsfleet International station and stretching across the Dartford and Gravesham boundary. Since 2015, Ebbsfleet Development Corporation has been the planning authority for the garden city's core area, separate from Dartford Borough Council, so BuildAlert's Dartford coverage — drawn from the borough's own planning register — mainly reflects the surrounding neighbourhoods and sites outside that boundary rather than the garden city's own reserved-matters applications. Swanscombe and Greenhithe, along the Thames, have seen major waterside regeneration around the old cement and paper works sites, with new residential schemes replacing former industrial land. Stone and Wilmington, on the borough's southern edge, keep more of a village character with older housing stock, generating a steadier flow of extensions and loft conversions. Dartford town centre itself has a conservation area around its historic High Street and parish church, where alterations to older buildings often need planning permission rather than falling under permitted development.
Here's a breakdown of the most common types of construction projects in Dartford over the past 30 days.
In Dartford, Extensions are the most common project type, appearing in 55 of the 75 leads tracked in the last 30 days, with Porches also showing consistent demand alongside New Builds. Projects can fall into more than one category, so these figures don't need to add up to the total.

In Dartford, the vast majority (83%) of planning applications are domestic projects such as extensions and loft conversions. Commercial developments make up a smaller portion but can offer higher-value opportunities for larger contractors.
Dartford's location — bordering south-east London and sitting on the M25, A2, and the Dartford Crossing — has driven sustained housebuilder interest across the wider Ebbsfleet area, even though the garden city's core development is planned through Ebbsfleet Development Corporation rather than the borough council. Within Dartford's own planning remit, Stone, Wilmington, and the older parts of Dartford town continue to generate consistent extension and refurbishment work, often at a solid mid-market spec reflecting the borough's mix of commuter families and established households, alongside smaller-scale new-build and infill sites on the fringes of the wider growth area.
Planning applications highlight upcoming work, giving you a chance to get in touch before builders are shortlisted.
Approved applications can be particularly valuable because the project has cleared a major planning hurdle and may be moving closer to construction.
Filter by estimated project value to focus your outreach on jobs that match the size and type of work your business takes on.
