I fired up LDD after making the 3D sketch for this idea, no running out of bricks that way! I kept building until I arrived at a height I liked, which just happened to be 8 floors – so it became Octo Mansions.
A companion block slanting the other way, and some landscaping on the Micropolis base plate and it was done!
I did think about using another colour apart from white, (I had already changed to use smokey trans bricks for the windows instead of clear), but there were few choices which I liked where I the parts needed are available. There are quite a few 1×2 jumpers required which are easy enough, but a matching Brick, Modified 1 x 2 x 1 1/3 with Curved Top (the pesky element which caused me grief with Rainbow Tower) comes in a fairly limited selection – none of which I really wanted to use for the whole model. So white it is.
