Extensions in Maidstone
A home extension adds new floor space to an existing property — commonly a rear or side-return kitchen extension, a wraparound, or a first-floor addition — and typically involves planning or permitted development approval, Building Regulations, and coordination of groundworks, structure, roofing and internal finishing.
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
Extensions in Maidstone: FAQs
Do you provide extensions 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 a rear extension?
Many single-storey rear extensions fall under permitted development if they meet size, height and boundary criteria. Larger extensions, those on designated land, or properties where permitted development rights have been removed, need a full planning application. We assess this during the feasibility stage.
What is a party wall notice and do I need one?
If your extension involves work at or near a shared boundary, the Party Wall etc. Act 1996 usually requires you to notify your neighbour before work starts. We flag this during design so notices can be served in good time.
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.
