The House of Tomorrow?

The film above shows a “house of tomorrow” somewhere in Blackheath. It was filmed by Pathe in 1957. Olly emailed me, asking if anyone knows where it is. Do you? I’d assumed it could be a Span House, but I’m not sure. Click the image to view, and try to ignore the irritating pre-roll advertisements. Terrible website for some great old newsreel clips.
