Balham’s homes: terraces, mansion blocks and flats
Balham’s streets are lined with Victorian and Edwardian terraced houses, especially in the Nightingale Triangle and around Tooting Bec Common. Many have been extended or converted, so pipe runs can be long and boilers are often working harder than they did originally.
Balham is also known for its mansion blocks and 1930s flats, most famously Du Cane Court, the Art Deco block on Balham High Road. In purpose-built blocks, plumbing is often stacked, access may need arranging with the building manager, and a leak in one flat can soon affect those below.
There are also many converted flats and rentals near Balham and Clapham South stations, which means plenty of landlords who need an annual Landlord Gas Safety Record.
