North Hill, Highgate N6 4AB
The orginal building, Walter Segal built his own single storey house in the back garden of his home whilst it was being renovated, despite it being only planned as temporary, it is still there until 2015. I have attempted to photograph it but it is in a back garden, so this the best photo I could take.
Sadly now demolished apparently it was in very poor state of
repair. It was only meant to be temporary building, however may be
replaced with the same footprint and in a Segal style, current
owner is a Segal fan and very interested in Segal self-build.
The 20th century society took photos.
