Have the booklet now so have been able to spend some time browsing through all the buildings that are on offer. Were time and distance no object (have realised that I have to be in Manchester for a meeting on the Saturday, grrrr) the places I would like to see the most would be:
79 Stoneleigh Terrace, Camden (described as "light-filled 1970's Brutalist terraced house") and 8 Stoneleigh Terrace, Camden (built by an architect who studied with Goldfinger).
Royal College of Physicans, Camden (Open House booklet says: Dramatic interior spaces and white mosaic exterior elevated on piloti. Grade I listed and one of London's most important post-war buildings).
No.1 Croydon (formerly NLA Tower), Croydon.
Langham House Close Flats, Richmond (already mentioned by Lang Rabbie, above. Described as "a landmark in Brutalism").
The Pioneer Health Centre, Southwark (Open House booklet says: Grade II listed Modernist building, described by Walter Gropius as "an oasis of glass in a desert of brick").

Definitely won't get to do all of those in one day but will try to do as many as I can on the Sunday.
Very troubled by the overuse of the words 'iconic' and 'aspirational' in the Open House booklet
