How much do planning drawings cost in London?
For a single project, such as one extension, a loft conversion or a new layout, a full set of planning drawings costs between £1,300 and £4,200. Flats and simple layout changes sit at the lower end, and larger houses at the upper end.
Three things drive the fee: the type of property, how many elements you're designing, and the size of the home. Every package starts with a measured survey, so the drawings are built on accurate information.
| Service | Typical fee |
|---|---|
| Measured survey | £600 to £900 |
| Planning drawings (full set) | £1,300 to £4,200 |
| Planning submission and agent service | £350 |
| Photoreal 3D visual | £500 each |
