Annexes in Maidstone
An annexe is self-contained living accommodation on the same plot as a main house, complete with its own kitchen and bathroom facilities, built either as a new detached structure, a conversion of an existing outbuilding, or an extension with its own entrance.
In Maidstone, that covers Allington, Barming, Loose, Penenden Heath, Tovil, Weavering, Bearsted. Maidstone is the county town of Kent, set on the River Medway, with a historic centre and a broad mix of Victorian terraces, interwar suburbs and newer estate development across the wider town and surrounding villages.

The town includes Victorian and Edwardian terraces close to the centre, substantial interwar semis in the surrounding suburbs, and more recent estate housing on the town's edges, alongside period cottages in the outlying villages.
Planning considerations
Maidstone Borough Council is the local planning authority. The historic town centre and several village centres in the borough are conservation areas, and some areas are at risk of flooding from the River Medway, which can affect ground floor extension and conversion design.

FAQs
Annexes in Maidstone: FAQs
Do you provide annexes across all of Maidstone?
Yes, we cover the ME14, ME15 and ME16 postcode areas in full, including Allington, Barming, Loose, Penenden Heath, Tovil, Weavering, Bearsted.
Do I need planning permission for an annexe?
Usually yes, because independent cooking, sleeping and washing facilities mean the structure is not treated as a simple outbuilding. Some annexes intended purely as ancillary accommodation for the main house can fall under permitted development, but this depends on size, position and local policy, which we check during feasibility.
Can an existing garage or outbuilding be converted into an annexe?
Yes, provided the structure is suitable and can be brought up to full Building Regulations standard for insulation, damp-proofing and services. We assess this as part of the feasibility stage alongside a new-build option.
Does flood risk from the River Medway affect extensions in Maidstone?
For properties in flood risk areas, extension design may need to take flood resilience into account, and a flood risk assessment can be required as part of a planning application. We check the Environment Agency flood mapping for your property during feasibility.
