Fitzroy Park

[1] The formerly rural setting of the road was significantly altered during the 20th century by the development of large private residences and high walls.

[3][4] The Hexagon, a gated housing development on Fitzroy Park, was built on the gardens of Witanhurst in the 1960s.

[2] The grounds of Fitzroy House were reputedly designed by Capability Brown, and extended across the whole of the present site of the modern road.

[6] Lorenz had originally situated the kitchen of the house facing north, toward a mudbank, but it was moved to overlook the garden after the complaints of Ruth Sørenson (known as "Li"), Arup's wife.

[3] The Historic England heritage listing praises the design of 8a as being " ... entirely of its time" as well as " ... one of the most adventurous in terms of complexity and in its method of separating the different functions of the house".

[3] 8a was depicted as the Draconian Embassy in scenes from the 1972 Doctor Who episode Frontier in Space, that were filmed at the house.

[4] In 1953 Harris purchased an adjoining house, Southampton Lodge, which was subsequently demolished to extend his garden to the south west.
