About Sefton Marsh

We take on around forty sales a year between the commons. The person who values your home is the person who shows it, negotiates it and rings you on a Sunday when the offer comes in. No call centre, no sixteen-week contract, no valuer you never see again.

No. 05 — Area guideFour neighbourhoods, three commonsp. 24

Between the commons. Four neighbourhoods we walk every day.

Our patch runs from Clapham Junction down to Tooting Bec, held together by three big commons. Here is how each part actually feels to live in.

Wandsworth Common

The “between the commons” streets: long runs of Victorian terraces, a Saturday that revolves around the common’s ponds and cafés, and a fifteen-minute train to Victoria. Families move here for the schools and stay for the quiet.

Typical 3-bed terrace
£1.3m–£1.6m
Typical 2-bed to rent
£2,600 a month
Getting in

Six people, one office, no call centre.
