MonoMonday: Architectural Glimpses

PelorusJack has posted this interesting challenge on behalf of Blackheath Blippers today.
It was too wet to really to justice to it so I took this as we crossed the Sydney Harbour Bridge this afternoon. 
We are in the city for a couple of days. Tonight I cooked dinner for Helen's birthday and Julia has joined us. 
Tomorrow evening we are going to a show.
The road to the valley looks like being out of action for at least the rest of the week till some temporary repairs can be done. A proper solution may take quite a while longer. Hence we might as well be here as can't get near the farm.
