Thanks gents!
So I'm moving house in a few days, so this will be the last update for a while! 1:1 scale projects come first(
.....or so the wife tells me! 
)
I managed to find a couple of oscillating fans the other day and started making them into tower blocks. My original plan was to use either vacuums or fans to build these. It seems that I've been a bit silly and now turned my fan INTO a hoover!

I think I might need to break up the shape of the base with some stuff around the outside. Maybe some buttresses or supports or something.
The inside reception with eventually have a back dividing wall cutting across from the lift entrance(the cylindrical shape in the middle) My is to have a security reception in there and some potted plants/trees in the corners.
