Double-storey extensions in Tipton

What should you know before starting in Tipton?

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

Party wall notices take one or two months to run, so they're best served as soon as planning is granted.
The householder planning fee in England is £548 from April 2026, paid to Sandwell Council when you apply.
Scaffolding is usually up for most of the build, so think about access along the side of the house early.

Which option fits your home?

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.

Building over an existing extension

Adds a first floor on top of an existing single-storey extension or attached garage. It can cost less because the footprint already exists, but a structural engineer must check the existing foundations and walls first, and they sometimes need strengthening. The old flat roof comes off and the new floor is tied into the main house.

How much should you budget in Tipton?

Expect to budget between £52,000 and £135,000 depending on size and specification in Tipton. A two-storey side extension on a three-bed semi, about 32 m² over two floors: typically £68,000–£88,000.

Questions about double-storey extensions in Tipton

Is a double-storey extension better value than a single-storey one?

Per square metre, usually yes. Foundations and roofs are the expensive parts of any extension, and on a two-storey build they serve twice the floor area. You'll pay more in total and planning is less certain, but if you need a bedroom as well as downstairs space, building both together normally costs less than two separate projects years apart.

Which postcodes in Tipton do you work in?

We cover DY4 and the streets around them. If you're on the edge of Tipton, neighbouring Tividale and Coseley 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.

Who approves double-storey extensions in Tipton?

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