Redcar, North Yorkshire
Two-storey rear extension in Redcar
A larger kitchen downstairs and an extra bedroom or bathroom upstairs, under one roof. We design, get the approvals for and build two-storey rear extensions in Redcar and the surrounding area, with one contract from the first survey to building control sign-off.
Redcar is covered from our North Yorkshire round, including TS6 and TS10. Two-storey rear extensions suit semi-detached houses in Redcar best, where the extra bedroom matters as much as the bigger kitchen.

How much does a two-storey rear extension cost in Redcar?
For Redcar we work from the North East England rate: £1,620–£2,430 per square metre of new floor, including VAT, standard specification. North East prices are among the lowest in our range; former mining ground is the main foundation variable.
| Size | Guide price inc VAT |
|---|---|
| 3 m × 5 m footprint, two floors (30 m²) | £48,500–£73,000 |
| 4 m × 6 m footprint, two floors (48 m²) | £78,000–£116,500 |
Your written price follows a measured survey and an agreed design, so it reflects your house, not an average.
Do you need planning permission for a two-storey rear extension in Redcar?
Whether your two-storey rear extension in Redcar needs a planning application depends on its size, your house and any local restrictions.
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 Redcar like to extend?
Brick terraces, colliery houses and post-war semis make up much of Redcar. Former mining areas often need a coal mining risk check before foundations are designed.

FAQ
Two-storey rear extension questions in Redcar
Do you handle building control in Redcar?
Yes. We apply to the council or a registered building control approver and hand over the completion certificate.
Do I need planning permission for a rear extension in Redcar?
Often not for a single-storey rear extension of up to 3 metres (4 metres on a detached house) under permitted development, or up to 6 or 8 metres with prior approval, unless the house is in a conservation area or its rights have been removed.
Can I add an en-suite upstairs?
Yes. We plan the soil pipe route early so the bathroom sits where drainage works without boxing through the room below.
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 Redcar?
Most single-storey rear extensions take 10 to 16 weeks on site and two-storey extensions 16 to 26 weeks, after design and approvals.
Will I need a structural engineer?
Yes for the beam over the new opening and usually the foundations; we arrange them and their calculations go to building control.
