Single-storey extensions in Rugby

Before your single-storey extension in Rugby

Before work starts on your single-storey extension in Rugby, two things get checked: whether planning permission from Rugby Borough 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.

Under permitted development, a rear extension on a semi or terrace can usually project 3 metres from the original back wall, or 6 metres through the prior approval route.
If you're building over or near a public sewer, the sewerage company has to agree before the foundations go in.
Detached houses get a little more room: 4 metres as standard, or up to 8 metres with prior approval.

Options to consider in Rugby

Rear kitchen-diner extension

The usual layout: a 3–6 metre extension across all or part of the back wall, with the old rear wall replaced by a steel beam so the new and existing rooms become one space. Roof lights or a lantern bring daylight into the middle of the house, and bifold or sliding doors open onto the garden.

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.

How much should you budget in Rugby?

Prices in Rugby match the rest of our area: £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.

Your questions answered

Can we live at home during the build?

Yes, most families stay at home throughout. For the first several weeks the work is outside and your house is closed off from it. The disruptive part is the break-through, when the back wall comes out and the kitchen may be out of action for one to three weeks. We agree a plan for a temporary sink and cooking space before that stage starts.

Which postcodes in Rugby do you work in?

We cover CV21 and the streets around them. If you're on the edge of Rugby, neighbouring Walsgrave and Binley are covered too.

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.

Will I need permission from the council in Rugby?

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