Double-storey extensions in Water Orton

Before your two-storey extension in Water Orton

Expect to apply to North Warwickshire Borough Council for planning permission for a two-storey extension in Water Orton; side extensions over one storey always need it. We prepare the drawings, and the structural work also needs Building Regulations approval.

The householder planning fee in England is £548 from April 2026, paid to North Warwickshire Borough Council when you 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.

Which options suit homes in Water Orton?

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.

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.

Double-storey extensions in Water Orton: common questions

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 Water Orton do you work in?

We cover B46 and the streets around them. If you're on the edge of Water Orton, neighbouring Coleshill and Castle Bromwich are covered too.

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.

Will I need permission from the council in Water Orton?

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