Before you get quotes for building work in Maidstone, check which rules apply to your home. Start with the council. Most of the area is in Maidstone borough, but Aylesford, Larkfield, Ditton and Kings Hill are in Tonbridge and Malling, and Walderslade and Lordswood are in Medway. Planning applications go to the council for your address. Maidstone Borough Council runs its own building control service.
Maidstone borough has 41 conservation areas, from the Town Centre and Holy Trinity Church to Loose Valley, Bearsted, Headcorn and Staplehurst. In these areas, you'll probably need planning permission for some work that would be permitted development elsewhere. In the Holy Trinity Church conservation area, near the town centre, an Article 4 direction removes permitted development rights for most changes to the outside of a house, from extensions and roof changes to porches and fences. Parts of Headcorn, Lenham, Loose Valley and Hollingbourne have Article 4 directions too.
Trees matter as well. The council has more than 1,000 tree preservation orders, and in a conservation area you must give six weeks' notice before most tree work. If a tree is in the way of an extension, check before anyone touches it.
If your home is near the Medway, the Len, the Loose or the Beult, check its flood risk on GOV.UK. An extension in a flood zone may need a flood risk assessment with the planning application.
The ground varies across the borough, from chalk on the North Downs to clay in the Low Weald villages such as Headcorn, Marden and Staplehurst. Your building control officer or engineer will set the foundation depth, especially near trees, and a good builder will allow for trial holes rather than guessing.
On terraced and semi-detached houses, work on or near a shared wall often needs a party wall agreement with your neighbours before it starts.
When you compare builders, ask for itemised quotes on the same drawings. Check that each quote says who deals with building control and what the payment stages are, and never pay large sums upfront. Reviews on Trade Pilot are tied to real, invoiced jobs, so you can see how a builder has handled projects like yours.

Many single-storey rear extensions fall under permitted development. That doesn't apply where an Article 4 direction removes those rights, such as the Holy Trinity Church conservation area. Conservation areas and flats have extra limits. Check with Maidstone Borough Council, or with Tonbridge and Malling or Medway council if your home is in their area.
Single-storey extensions typically cost £1,800 to £3,000 per square metre across the UK. Maidstone and the wider South East often come in above that. The finish, glazing and kitchen can make a big difference.
Check first. Maidstone has more than 1,000 tree preservation orders, and in a conservation area you must give the council six weeks' notice before most tree work.
Often, yes. If you're building on or near a shared wall, or digging foundations close to a neighbour's, you normally need to serve notice under the Party Wall etc. Act 1996 before work starts.
Avoid large upfront payments. Agree stage payments tied to finished work, and get a written contract that sets out the scope, price and timings.
Yes. Posting a job and receiving quotes is free for homeowners, and you don't have to accept any quote.
