Kent

England's 'Garden of England', a county of hop fields, orchards, white cliffs, and historic castles on the South East coast.

Most Important Things to Consider in Kent Before Self Build

The most critical considerations before a self-build in Kent include plot availability, planning constraints, and budget contingency. Check the local plan policies for your area, identify any AONB, green belt, or flood risk designations on your site, and confirm you are registered on the local authority's self-build register before securing land.

Where to Start With Self Build

The self-build process begins with research: understand your local planning authority's policies, register on the self-build register, and establish a realistic budget. Source land through specialist agents or custom-build developments. Before buying, get an architect's view on planning viability. Arrange your self-build mortgage and warranties early - lenders and insurers have specific requirements.

Things to Get a Specialist For Even When Self Building

No matter how much you self-manage, always use qualified professionals for structural design, building regulations sign-off, electrical certification, gas commissioning, and legal conveyancing. On complex sites, specialist planning consultants, ecologists, arboriculturalists, and drainage engineers may be legally required. Skimping on expertise at these stages creates risk that can block your mortgage and future sale.

Kent, the Garden of England, is a county of rich agricultural character, outstanding historic heritage and significant development pressure from its position between London and the Channel ports. As the gateway to Europe, Kent's planning environment reflects a unique blend of outstanding landscape quality, intensive farming, significant infrastructure requirements and strong residential demand from both London commuters and those attracted by the county's own growing economy.

Kent is a two-tier county with Kent County Council and twelve district and borough councils - Ashford, Canterbury, Dartford, Dover, Folkestone and Hythe, Gravesham, Maidstone, Sevenoaks, Swale, Thanet, Tonbridge and Malling, and Tunbridge Wells. Each district maintains its own self-build register and planning service. Medway Council is a separate unitary authority covering the Medway towns of Rochester, Chatham, Gillingham, Strood and Rainham.

The Kent Downs AONB and the High Weald AONB (which extends into west Kent from East Sussex) are the primary landscape designations constraining self-build development in Kent. The Kent Downs AONB covers the chalk escarpment from the Thames Estuary near Gravesend to the Dover Cliffs and inland across the high downland north of Ashford. Planning policy within the AONB prioritises landscape conservation and requires self-build proposals to engage with the Chilterns and Kent Downs Building Design Guide, which provides guidance on materials, proportions and building forms appropriate to the chalk downland vernacular of flint, ragstone, red brick and weatherboarding.

The Metropolitan Green Belt covers parts of north-west Kent, particularly around Dartford, Gravesham and Sevenoaks. The Sevenoaks district is among the most Green Belt-constrained in England, with over 90 percent of its area in the Green Belt. Self-build opportunities in Sevenoaks are largely restricted to infill within settlement boundaries and replacement dwellings. Planning advice before purchasing any site in this district is essential.

Canterbury is one of England's most significant historic cities, with a World Heritage Site encompassing the Cathedral, St Augustine's Abbey and St Martin's Church. Planning in Canterbury involves careful assessment of heritage impact on the World Heritage Site and its buffer zone. The Canterbury City Council's planning service is experienced in advising on the specific requirements for development in and around this exceptional historic environment.

The Kent coast from Whitstable through Herne Bay, Margate, Broadstairs and Ramsgate to Deal and Sandwich offers coastal self-build opportunities in an area that has seen significant property market growth driven by improved rail connections to London St Pancras. Thanet's creative community and Folkestone's arts scene have attracted design-conscious buyers seeking coastal self-build plots at prices significantly below those of other southern counties.
