Double-storey extensions in Penkridge

Before your two-storey extension in Penkridge

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

Under permitted development, a rear extension of more than one storey can project no more than 3 metres and must be at least 7 metres from the rear boundary.
The householder planning fee in England is £548 from April 2026, paid to South Staffordshire Council when you apply.
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 Penkridge

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.

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.

Before you book in Penkridge

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.

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 Penkridge?

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