The map

Every line a planning officer will look at.

The same government data your council consults, over any site in the United Kingdom, on a street basemap so the constraints read as data rather than as mud over a photograph.

Real capture

This is the actual product.

Bath city centre with the heritage group switched on: every listed building and the conservation area boundary, over the street basemap.

The Wren map showing Bath city centre on a street basemap, with listed buildings and the conservation area boundary switched on, and the layer catalogue open on the left.
Bath and North East Somerset, BA1 1DG. Three heritage layers active. The panel on the left is the live layer catalogue, not a picture of one.

A sample

Five of the eighty-eight.

Each one is drawn from the body that publishes it, refreshed on its own schedule, and named on the data page so you can go and check it. Every capture below is the bare map at one scale and one frame, at the zoom where that layer actually reads.

The Wren drawing tools: polygon, rectangle, circle and measure, over a street basemap.
Draw a boundary, measure it, and the tools stay out of the way of the map underneath.

Drawing

Draw the red line yourself.

A polygon, a rectangle, or a circle at a radius you set. Snap it to a boundary, measure an edge, and the area is computed as you draw. That red line is the input to everything else Wren does.

Nothing you draw is public and nothing needs an account to try.
