Builders in Totteridge

In Totteridge and Whetstone we work on everything from large detached houses in a green setting to semi-detached homes near the tube, with close attention to the conservation area and Green Belt.

Homes in Totteridge

Totteridge mixes suburban housing with open land and some farmland. After the Great Northern Railway station opened in 1872, late-Victorian and Edwardian mansions were built around the old village, and in the late 1930s smaller houses followed within walking distance of what became Totteridge and Whetstone tube station. Spacious detached houses stand in a green setting, while more modest, mostly semi-detached housing predominates at the eastern end.

At the 2021 Census, 67% of households in Totteridge and Barnet Gate and in Whetstone East lived in houses: 32% semi-detached and 24% detached. Median semi-detached prices were about £770,000 to £900,000 in the year to March 2026.

The older village includes some of the area's most sensitive buildings: Tudor-era timber-framed houses such as Willow House and Rose Cottage, and the Pound House, built in 1907 by the Arts and Crafts architect J L Williams. Work near buildings like these needs particularly careful detailing.

Planning and practical notes for Totteridge

Much of Totteridge was designated a conservation area in 1968, and there has been little major development since. The open land around it is Green Belt, which strictly limits how far houses can be extended. Inside the conservation area, side extensions and roof alterations need planning permission and are judged on how they affect the area's spacious, green character.

In Whetstone and other streets outside the conservation area, Barnet's 2026 guidance applies, including a 1-metre gap to the boundary at first floor for two-storey side extensions and a set-down of 0.5 metres from the main ridge, so that gaps between houses are preserved. National Green Belt policy also treats extensions that are disproportionate to the original building as inappropriate, so the size of any earlier extensions matters.

Building work in Totteridge: common questions

Extensions in the Green Belt are possible but limited: national policy treats additions that are disproportionate to the original building as inappropriate development. Barnet will look at the combined size of all extensions since the house was built.

Much of Totteridge was designated in 1968. Barnet publishes a character appraisal explaining what makes the area special.
