Tweeddale is located at the heart of the St. Helier Estate. It is named after Lady St. Helier who was a London County Councillor and Alderman – her special interest being the improvement of conditions for the poor. The estate was designed as a garden estate incorporating parks and open spaces, and public facilities. Tweeddale is built on land once owned by the Miller family who were nurserymen and market gardeners. They grew lavender, watercress and herbs.
In 2003, the infants and junior schools merged to become a primary school with nursery provision. The merged school has been based on the Tweeddale Road site since then and the infants school was demolished to make way for housing.
