Double-storey extensions in Tamworth

Double-storey extensions in Tamworth: approvals and local details

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

An upstairs en-suite is simplest when the new bathroom sits close to the existing soil stack.
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.
Scaffolding is usually up for most of the build, so think about access along the side of the house early.

Choices to weigh up in Tamworth

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.

Combined side and rear

An L-shaped two-storey build wrapping the side and back of the house gives the biggest gain, sometimes two extra bedrooms. It's a substantial project with more steel and a complex roof junction, and it will need a householder planning application. Expect a longer programme and a careful plan for keeping the house secure while the roofs are joined.

Double-storey extensions in Tamworth: common questions

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.

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 Tamworth Borough Council need to approve my two-storey extension?

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