What Are House Extension Plans?
House extension plans are detailed architectural drawings used to support planning permission applications and building regulation approvals. They typically include:
- Existing and proposed floor plans
- Elevations (front, side, rear)
- Site and location plans
- Structural layout or load-bearing wall details
- Building control information
These plans are required whether you’re applying for full planning permission or using permitted development rights.

A combination of rear and side extensions that dramatically increase downstairs space.

Frequently Asked Questions.
That depends on the size and placement of the extension. Many single storey rear extensions fall under permitted development, but others — like side or two-storey extensions — usually need planning permission. We’ll advise you during the consultation.
Yes. We offer a full planning application support service where we submit your application to the council and act as your agent throughout the process.
Prices vary depending on the size and complexity of your extension. We offer fixed, transparent pricing after an initial consultation — no hidden extras.
If you’re removing a wall, installing steel beams, or building two storeys, yes — structural calculations will be required for building control approval. We can provide these alongside your architectural plans.
Most draft plans are ready within 5–7 working days of the site survey. Urgent turnaround may be available if needed.
Absolutely. We often collaborate directly with builders and contractors to ensure the plans are practical, cost-effective, and buildable on site.
