What are the steps to getting an extension on house?

The first step is to arrange a site visit with a reputable builder or architect to discuss your ideas, budget and what's achievable. They can advise if planning permission is required or if the project falls under permitted development. Once the drawings are prepared, Building Regulations approval can be arranged. After that, obtain a detailed quotation, agree a contract with a payment schedule and start date, then work can begin. A good builder will normally guide you through the whole process from design to completion and people preferred in these days to get all under one roof.
