Double-storey extensions in Walsall Wood

What should you know before starting in Walsall Wood?

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

A side extension of more than one storey always needs a householder planning application.
New first-floor bedrooms normally need an escape window with at least 0.33 m² of clear openable area.
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 Walsall Wood

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.

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.

Questions about double-storey extensions in Walsall Wood

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 Walsall Wood?

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 Walsall Wood?

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.
