Alexandra Crescent was built as a private (unadopted) road in late 1925 by the developer Albert Frampton. In a last-minute change of name, it was called after Queen Alexandra of Denmark who had just passed away in November of that year.

As the Downham Estate was being built to the north in 1926, those who were just moving into the new Alexandra Crescent appointed Frampton to build a dividing wall. The private home owners wished to prevent the working class people of Downham from accessing their neighbouring middle-class area. The Alexandra Crescent residents also wanted to prevent the development of an access route into the centre of Bromley.

Frampton made a formal application to Bromley Council on 16 February 1926 to build the dividing wall. The council refused to take a decision but the seven-foot-high brick wall was built nonetheless. It was constructed across Valeswood Road at its junction with Alexandra Crescent.

The ’class wall’ was the forerunner of the gated communities, barrier-walls and the use of private security which became more common decades later.

The wall was removed in 1950.
