Single-storey extensions in Studley

What should you know before starting in Studley?

Planning applications and lawful development certificates for Studley go to Stratford-on-Avon District Council. Many single-storey extensions fall under permitted development, but not every house keeps those rights — conditions on newer estates, conservation areas and Article 4 directions can remove them. The structural work also needs Building Regulations approval, through the council's building control team or a registered building control approver.

Under permitted development, a rear extension on a semi or terrace can usually project 3 metres from the original back wall, or 6 metres through the prior approval route.
If you're building over or near a public sewer, the sewerage company has to agree before the foundations go in.
A lawful development certificate from Stratford-on-Avon District Council confirms in writing that a permitted development extension is lawful, which helps when you sell.

Options to consider in Studley

Flat roof or pitched roof

Flat roofs, usually GRP fibreglass or EPDM rubber, keep the height down near boundaries and suit roof lanterns. Pitched or lean-to roofs with tiles to match the house look more traditional and shed rain faster, but need more height. The choice affects permitted development limits, cost, and how much light reaches the existing rooms.

Rear kitchen-diner extension

The usual layout: a 3–6 metre extension across all or part of the back wall, with the old rear wall replaced by a steel beam so the new and existing rooms become one space. Roof lights or a lantern bring daylight into the middle of the house, and bifold or sliding doors open onto the garden.

How much should you budget in Studley?

Guide prices start at £28,000 and run to £90,000 depending on size and specification. A 4 m × 5 m rear extension on a semi, with roof lights and bifold doors: around £40,000–£52,000.

Single-storey extensions in Studley: common questions

How long does a single-storey extension take?

Allow 8–12 weeks on site for most single-storey extensions, plus time beforehand for drawings and approvals. If you need a planning application or a lawful development certificate, councils aim to decide within 8 weeks. Glazing and steel are ordered early so they arrive when the shell is ready, which keeps the build from stalling halfway.

How do I book a survey in Studley?

Send the form on this page, use the guide-price tool or call 0800 088 6248 free. We'll ask a few questions about your single-storey extension and arrange a time to visit.

What should I prepare before the survey?

Think about how you want to use the new space, and gather anything you have about the house: old plans, deeds showing boundaries, approvals for any earlier extension, and where you think the drains run. Photos of extensions you like help us price glazing and finishes accurately. If you're in a conservation area or on a newer estate, mention it, as it can affect permitted development.

Who approves single-storey extensions in Studley?

Usually building control, and sometimes planning. Stratford-on-Avon District Council is the planning authority for Studley; Building Regulations approval comes from its building control team or a registered building control approver. We'll tell you which applies after the survey.
