Frequently Asked Questions
Do I need planning permission for my extension or conversion?
- Not always. Many small extensions, loft conversions, and garage conversions can be built under Permitted Development (PD) rights without needing full planning permission.
However, they still require technical drawings to prove they meet these strict criteria. We will assess your project during our initial consultation and advise on the best route.
What is the difference between Planning Permission and Building Regulations?
- Planning Permission deals with the look of the project and its impact on your neighbours and the local area.
- Building Regulations focus on structural safety, insulation, fire safety, and construction standards.
- Hampshire Home Plans specialises in the architectural planning drawings and council submissions needed to get your project approved through the planning stage.
How long does the council planning process take?
- Once we submit your application, most local councils in Hampshire and the surrounding areas take roughly 8 to 12 weeks to issue a decision on standard residential extensions and conversions.
What is a Lawful Development Certificate, and do I need one?
- If your project falls under Permitted Development, a Lawful Development Certificate (LDC) is formal proof from the council that your build is completely legal and didn’t require planning permission.
While not always legally mandatory before building, it is highly recommended. It protects you from council disputes and is essential if you ever sell your home.
Can you use old drawings of my house, or do you need to do a survey?
- While old drawings or estate agent floorplans are helpful for reference, we almost always need to conduct a fresh measured building survey.
Even minor discrepancies can cause structural issues later, so we ensure every millimeter of your existing layout is accurately mapped out before design work begins.
What happens if my planning application is refused?
- Because we have over 15 years of experience, we design with local policies in mind to minimise this risk.
However, if the council requests changes, we act as your agent to liaise with the planning officer, modify the designs where possible, and resubmit the application to give it the best chance of approval.
