Single-storey extensions in Bilston

What should you know before starting in Bilston?

Before work starts on your single-storey extension in Bilston, two things get checked: whether planning permission from City of Wolverhampton Council is needed, and how Building Regulations approval will be obtained. If you share a wall with a neighbour, the Party Wall etc. Act 1996 may apply as well.

Every extension needs Building Regulations approval, even when planning permission isn't required.
Foundations within 3 metres of a neighbour's house that go deeper than theirs need party wall notice at least a month in advance.
Wide glazed doors and roof lights make the biggest difference to how bright the new room feels, and to the final price.

Which options suit homes in Bilston?

Utility, WC or boot-room extension

A smaller extension of 6–12 m² can take the washing machine, coats and a downstairs toilet out of the kitchen. Adding a WC means a new waste connection, so the position of the existing drains often decides the layout. It's a cost-effective way to free up the main rooms without a large build.

Side or side-return extension

Uses the strip of land beside the house, often a passage or driveway. Under permitted development a side extension can be up to half the width of the original house and no more than 4 metres high. On a terrace with a narrow side return, it can widen a galley kitchen considerably without eating into the garden.

What does your single-storey extension cost in Bilston?

For a home in Bilston, our guide range is £28,000–£90,000 depending on size and specification. A 4 m × 5 m rear extension on a semi, with roof lights and bifold doors: usually £40,000–£52,000.

Single-storey extensions in Bilston: common questions

What should I prepare before the survey?

Think about how you want to use the new space, and gather anything you have about the house: old plans, deeds showing boundaries, approvals for any earlier extension, and where you think the drains run. Photos of extensions you like help us price glazing and finishes accurately. If you're in a conservation area or on a newer estate, mention it, as it can affect permitted development.

Which postcodes in Bilston do you work in?

We cover WV14 and the streets around them. If you're on the edge of Bilston, neighbouring Willenhall and Darlaston are covered too.

What guarantees come with the extension?

Windows, doors, roof lights and roofing membranes come with manufacturers' guarantees, and the terms for each product are set out in your quote. Building control's completion certificate confirms the work met Building Regulations when inspected. If anything in our workmanship isn't right after handover, call us and we'll come back and look at it. Ask us for current insurance details with your quote.

Who approves single-storey extensions in Bilston?

Usually building control, and sometimes planning. City of Wolverhampton Council is the planning authority for Bilston; Building Regulations approval comes from its building control team or a registered building control approver. We'll tell you which applies after the survey.
