Double-storey extensions in Aldridge

Before your two-storey extension in Aldridge

Planning permission from Walsall Council is the first hurdle for most double-storey extensions in Aldridge. 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.
Councils often expect a side extension's first floor to be set back from the front wall, with its roof below the main ridge.
An upstairs en-suite is simplest when the new bathroom sits close to the existing soil stack.

Which options suit homes in Aldridge?

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.

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.

Questions about double-storey extensions in Aldridge

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.

Which postcodes in Aldridge do you work in?

We cover WS9 and the streets around them. If you're on the edge of Aldridge, neighbouring Rushall and Walsall Wood are covered too.

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.

Who approves double-storey extensions in Aldridge?

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.
