Quick summary

When commissioning floor plans, start with existing and design plans, which are essential for planning permission or lawful development certificates. These typically cost around £200 to £600, depending on size and detail, and should be prepared by a reliable architect with quick turnaround. Elevations are also useful for visualising external or internal changes.

If you’re thinking about extending or converting your home, the best place to start is with a set of floor plans. In fact, you can’t build without them!

Before you specify the types of floor plans that you need, you should start by finding out if your proposed house extension or loft conversion falls within permitted development rights. If you’re not sure, you can book a free consultation call with our friendly architectural experts and we’ll find out for you!

Many house extensions and loft conversions can go ahead without planning permission under permitted development rights, but you should still apply for a lawful development certificate. This is a similar process to a planning application, and is highly recommended, as it will protect you when you need to sell your home.
