Local to Folkestone
Postcode districts we cover around Folkestone include CT18, CT19, CT20. Neighbouring towns we cover include Dover (7 miles), Ashford, Kent (13 miles), Deal (14 miles), Canterbury (14 miles).
Just over the East Sussex border, Hastings is about 30 miles away. In the South East, plenty of houses have already been extended once, which makes checking the remaining permitted development allowance an important early step.
What is included
- Kitchen-led layout planning before the drawings are fixed
- Kitchen fitting by our team or coordination with your supplier
- Drainage and services designed for sinks, island and appliances
- Extraction routes and ventilation for building regulations
- Roof lantern or rooflights positioned over the work zones
- Wide sliding or bifold doors to the garden
We start with the working triangle and the island, then set the doors, glazing and roof lights around it. Getting this order right avoids the classic mistakes: a sink against a blank wall, glare on the hob or a fridge blocking the garden view.

Will the council need to approve it?
In England a single-storey rear extension can usually go up to 3 m beyond the original rear wall of a semi-detached or terraced house, or 4 m on a detached house, without a planning application, provided it is no more than 4 m high, keeps eaves to 3 m within 2 m of a boundary and, with other buildings, covers no more than half the land around the original house. The larger home extension prior approval scheme raises those depths to 6 m and 8 m, with neighbours notified and a 42-day decision.
The planning position for a specific Folkestone address depends on its history and any designations, which is why we check it at the first visit.
Building regulations approval is separate from planning. In England you can use the council's building control team or a registered building control approver; a full plans application gets the drawings checked before work starts, and the inspector signs the work off with a completion certificate.
Applications are decided by the local planning authority (your district, borough or unitary council).
How the project works
Site visits are free and there is no obligation. Where drawings are needed, the design stage is priced in writing before it starts.
Free site visit
A designer visits, takes measurements and photos, and discusses layouts, budget and timing with you.
Design and approvals
We produce the drawings and structural design, and manage the approvals so they are in place before work starts.
Fixed written price
You receive a written, itemised price and programme. Nothing starts until you are happy with it.
Build and sign-off
We build it with one project manager, book the building control inspections and hand over the completion certificate.
Kitchen extension questions answered
Do I need building regulations approval in Folkestone?
Yes. Almost every extension needs it, whatever the planning route. We prepare the drawings and book the inspections.
Do you cover all of Folkestone?
Yes. We cover Folkestone and the surrounding parts of Kent. Site visits are free and there is no obligation.
Who do I contract with for a kitchen extension in Folkestone?
Your contract is with S&K Property Investments and Improvement Ltd, which designs and manages the project and the build teams who carry it out.
Where should the island go?
Usually under the brightest part of the roof and away from the main walkway to the garden. We test two or three layouts on the plan before deciding.
How much does a kitchen extension cost?
For the extension itself our guide range is about £2,020 to £3,920 per m² including VAT. A standard 20 m² kitchen extension is typically around £47,000 to £59,500 in Folkestone, plus the kitchen itself, which commonly adds £9,000 to £20,000 for a mid-range design.
