Double-storey extensions in Pelsall

What should you know before starting in Pelsall?

Planning permission from Walsall Council is the first hurdle for most double-storey extensions in Pelsall. 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.
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 Walsall Council when you apply.

Options to consider in Pelsall

Two-storey rear extension

Adds depth to both floors across the back of the house: a kitchen-diner below and a larger bedroom or new bathroom above. Permitted development only covers projections up to 3 metres and at least 7 metres from the rear boundary, so many rear builds still need planning. Overlooking and loss of light to neighbours are the usual tests.

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.

Before you book in Pelsall

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.

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.

Will I need permission from the council in Pelsall?

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