I remember these Viv. In Landswood Close off Sidcup Road, they were a group of what we called mono pitch houses. The roof sloped in one direction.
At the time, I nearly fell through the floor when I was told they they had allegedly won an award for design. They had an enormous living room with a really high ceiling that sloped right down to normal height at the other end. Just a load of empty space that must have cost a fortune to heat. The bedrooms were a similar design. I think they had a warm air gas heating system too. Kingstanding Beacon was always quite cold and windy so they were always losing the mono pitch ridge tile that was quite hard to source.
The architect J A Maudsley of course won a reputation for all the wrong reasons in his own right and is worthy of another thread. In my opinion some of his social housing designs were dreadful. I think he turned the 60’s reference library into the cheap and cheerful looking thing it became in a cost cutting exercise.
