Double-storey extensions in Sheldon

What should you know before starting in Sheldon?

Planning permission from Birmingham City Council is the first hurdle for most double-storey extensions in Sheldon. 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.
A side extension of more than one storey always needs a householder planning application.
Scaffolding is usually up for most of the build, so think about access along the side of the house early.

Which options suit homes in Sheldon?

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.

What does your two-storey extension cost in Sheldon?

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.

Do you cover Sheldon?

Yes. Sheldon (B26) is about 10 miles from our West Bromwich base and inside the area we cover. Call 0800 088 6248 or send the form on this page to book a free survey.

Can we stay in the house while you build?

Most families do. The early stages are outside, and the existing house stays closed off until the shell is weathertight. The harder weeks are when openings are cut through on both floors, which brings dust and noise into bedrooms and the kitchen. We sheet off openings, lock up securely every night and agree in advance which rooms you'll lose and when.

Who approves double-storey extensions in Sheldon?

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