The story of the large house Trevenen on Westbourne Street Highgate Hill follows a pattern that is all too familiar. Built between the 1870s and 1880s to house a large affluent family, it was modernised in the 1920s when it enjoyed its social heyday. Trevenen became a mixed family home and flats for some years before being divided into 7 flats for over 60 years. Over time, its condition has steadily deteriorated and demolition has been approved.
