A Streamline Building in Cape Town

This streamline art deco building is in downtown Cape Town. I saw it during the 2003 World Congress on Art Deco but it wasn't part of the tour so I don't know what building it is at all.

I know where it is. Diagonally opposite Muller's Optomerists. Maybe someone from Cape Town can identify it for me.

It has this fabulous stepped clock on the corner above the verandah but looks a bit unloved.
