Here are a load more buildings you could do that I haven't seen you do yet:
Liftville Mall
Townscape
Arc La Defence
Varna SkyTower
CitiCom Tower
Epicentrum
Coalham Office
Coalham Library
Himmelstor Hospital (This building might need an older version of Skyscraper to run efficiently)
Thaddeus Building Mod
Unity Centre High Office Building
Simple - Gen2 Euro
Kings Grand Mall
Cliveden Desmond Wharf
Cliveden Mall
Liftville Toilet Towers
Club Scratch
Modernham Towers Renovations
Of those buildings, I have only
12 of them currently in my buildings folder. The others were likely on the old forum, though.
EDIT: Found about 6 of buildings posted here over a year ago, raising that count to 12. They will be added onto my planned buildings page for reference to be done soon.
