How we know the size

01

We collect

Every new flat to rent in London, checked through the day, seven days a week.
02

We read the floorplan

A vision model reads the plan the way you would — room by room, taking the dimensions printed on it. It is an AI estimate, and it can be wrong.
03

We measure

That gives a square footage, and a price per square foot. You can sort and filter on both. The portal offers neither.
