A community effort

The city has the space. The families have the need. Only the address is missing.

Right now in London, tens of thousands of families have nowhere settled to call home — while millions of square feet of commercial space sit dark and empty. You can help close that gap. If you know of an empty building, tell us exactly where it is. We'll do the rest.

Why it matters

We don't have a shortage of buildings. We have a shortage of imagination.

Every empty office was once full of people. With the right approach, it can be full of people again — not at desks, but at kitchen tables. Four Square turns vacant commercial buildings into managed homes for families referred by their local council, in their own borough, close to their schools and support. Owners keep their building. Councils get capacity. A family gets a front door. All it takes to start is someone who noticed an empty building and decided to say something.

You spot it

A building you pass on your commute, near your home, or where you work — empty for months or years.

We look into it

Our team checks whether the building could work as community accommodation and approaches the owner.

A family moves in

If it works, the building becomes a managed home for people referred by the local council — in their own borough.
