Watch Tower House

Site History, Planning, Tenure, Viewing & other details

Mill Hill’s proximity to the city of London made it popular as a country retreat from the 17th century onwards, and large houses and quaint cottages were constructed, many of which still remain.”

The earliest record of Mill Hill (or ‘Myllehill’) is dated 1547. The name appears to mean the ‘hill with a windmill’. In a building adjacent to the ‘Mill Field’ at the northern extent of The Ridgeway, the workings of the original Mill can be found. Mill Hill village is the oldest known inhabited part of the district, a ribbon development along the medieval route called ‘The Ridgeway’. Mill Hill’s proximity to the city of London made it popular as a country retreat from the 17th century onwards, and large houses and quaint cottages were constructed, many of which still remain.

Watch Tower House was constructed on the site of Bittacy House, a plain stuccoed villa which was described by Whishaw as ‘modern’ in his Map of Hendon and accompanying reference book of 1828. A foundation stone adjacent to one of the principal entrances noted the construction date of 1827. By the mid 1940’s, Bittacy House was already in a state of deterioration and by the early 1950’s the house had been demolished. Following the purchase of the site in the mid 1950’s by IBSA, Watch Tower House was constructed, with occupation commencing from 1959.
