Two-storey rear extension in Kidderminster
For homes in Kidderminster, a two-storey rear extension is often the simplest way to gain space without moving. A larger kitchen downstairs and an extra bedroom or bathroom upstairs, under one roof. We take it from survey to completion certificate.
Kidderminster and its postcode districts DY10 and DY11 are part of our Worcestershire coverage. In Worcestershire we check the neighbours' rear windows first, because the upper floor is where most two-storey schemes win or lose planning.

Do you need planning permission for a two-storey rear extension in Kidderminster?
Planning for a two-storey rear extension in Kidderminster follows the English householder rules.
England's rules allow a rear extension of more than one storey without an application only when it is no deeper than 3 metres and at least 7 metres from the boundary opposite the rear wall, and never on designated land. Most two-storey schemes need householder planning permission.
Conservation areas, National Parks, National Landscapes and the Broads restrict permitted development, and listed buildings always need listed building consent. Before any drawing we look up the property's history with the council, because earlier extensions and removed rights change the answer.
What are homes in Kidderminster like to extend?
Red-brick terraces and 1930s semis make up much of Kidderminster. Many already have a small kitchen lean-to at the back, which a new rear extension usually replaces rather than adds to.

Two-storey rear extension questions in Kidderminster
How much does a two-storey rear extension cost in Kidderminster?
As a guide, £1,800–£2,700 per square metre including VAT for a standard specification. For example, 3 m × 5 m footprint, two floors (30 m²): about £54,000–£81,000 at that rate. Your written price follows the survey.
Do you handle building control in Kidderminster?
Yes. We apply to the council or a registered building control approver and hand over the completion certificate.
Is two-storey cheaper per square metre than single-storey?
Usually yes, because the foundations and roof are shared across twice the floor area. The total cost is higher.
Who will build my extension?
Vetted building teams working under contract to us. Your contract is with S&K Property Investments and Improvement Ltd for the design and the build.
How long does a rear extension take to build in Kidderminster?
Most single-storey rear extensions take 10 to 16 weeks on site and two-storey extensions 16 to 26 weeks, after design and approvals.
Do I need a party wall agreement?
In England, usually yes if the extension is on or near a shared boundary or the foundations are close to a neighbour's building. We serve the notices.
