What we take care of
- Roof lantern or rooflights positioned over the work zones
- Wide sliding or bifold doors to the garden
- Extraction routes and ventilation for building regulations
- Kitchen fitting by our team or coordination with your supplier
- Kitchen-led layout planning before the drawings are fixed
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.
Planning rules that apply in Rickmansworth
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.
Before any drawing is finalised we check whether the house is listed, in a conservation area or subject to an Article 4 direction.
Building over or within 3 m of a public sewer needs the water company's consent, usually through a build-over agreement, before the foundations go in.
Applications are decided by the local planning authority (your district, borough or unitary council).

Your questions about a kitchen extension in Rickmansworth
Can I see a price before committing to anything?
Yes. The guide prices on this page are adjusted for Rickmansworth, and the guide-price tool gives a range for your own size. After the survey you get a written price before anything is agreed.
Who do I contract with for a kitchen extension in Rickmansworth?
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.
Will my neighbours in Rickmansworth be involved?
If a planning application or prior approval is needed, the council notifies neighbours. If the work is on or near a shared boundary, party wall notices may also be needed.
Can you fit a kitchen I buy elsewhere?
Yes. We can fit it or work with your supplier’s fitters. We need the layout early so that drains, services and lighting are in the right place.
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.
