About this creation
Small Office Block with tower block mounted on a turntable on top of a podium. The tower block has two different window treatments to test the possibilities of the various brick types (by just turning the block around). There are two water features on the roof of the podium and the roof of the office tower houses solar panels and four water tanks.
Quoting Paul Wellington
I've never even thought of using sloped bricks on a facade like that, I may have to borrow this technique (giving you credit of course). Nice job.
There is actually a ladies' hostel at the University of Pretoria that has a window treatment very similar to my model. I bought the mini-slopes and grill blocks per weight at my local Lego store - South African version of Pick-a-Brick... :-)
