Double-storey extensions in Bedworth

Double-storey extensions in Bedworth: approvals and local details

Planning permission from Nuneaton and Bedworth Borough Council is the first hurdle for most double-storey extensions in Bedworth. Householder applications have an eight-week target for a decision, and Building Regulations approval and the Party Wall Act may also apply.

New first-floor bedrooms normally need an escape window with at least 0.33 m² of clear openable area.
Under permitted development, a rear extension of more than one storey can project no more than 3 metres and must be at least 7 metres from the rear boundary.
Councils often expect a side extension's first floor to be set back from the front wall, with its roof below the main ridge.

Which option fits your home?

Two-storey side extension

Built over the side of the house, often where a driveway or old garage sits. It can create a garage, utility or study downstairs with a double bedroom above. Councils often expect the upper floor to be set back from the front and the roof to sit lower than the main ridge, so the design needs care to win approval.

Mixed-height extension

A two-storey section at the side with a single-storey section running across the back. This keeps the first floor away from neighbours' windows while still giving a wide kitchen-diner below. It's a practical compromise where planners have concerns about a full-depth two-storey rear extension, and it often simplifies the roof.

How much should you budget in Bedworth?

Guide prices start at £52,000 and run to £135,000 depending on size and specification. A two-storey side extension on a three-bed semi, about 32 m² over two floors: around £68,000–£88,000.

Your questions answered

What paperwork will I have at the end?

You'll get the building control completion certificate, the electrical installation certificate, your planning decision notice and the manufacturers' guarantee documents for windows, doors and roof products, with their terms set out in your quote. Keep these together, as a buyer's solicitor will ask for them when you sell. Ask us for current insurance details with your quote.

Which postcodes in Bedworth do you work in?

We cover CV12 and the streets around them. If you're on the edge of Bedworth, neighbouring Nuneaton and Walsgrave are covered too.

How long does a double-storey extension take?

Plan on 14–22 weeks on site, depending on size and roof complexity. Before that, allow time for drawings, a planning decision (councils aim to decide householder applications within 8 weeks), Building Regulations drawings and party wall notices. It's worth starting the design well ahead of when you need the space, because the approvals stage can take as long as the build.

Does Nuneaton and Bedworth Borough Council need to approve my two-storey extension?

Usually both. Most two-storey extensions need a planning application to Nuneaton and Bedworth Borough Council, and the structural work needs Building Regulations approval from its building control team or a registered building control approver.
