Yup, generally it seems the first couple of (unique) floors often take about a month or more. Once the building starts to rise and the floorplates become more consistent, they'll often shoot up at a floor every 7-10 days.
I am a little bit confused. What is the last design for this building? I'm hoping it's the one with the window black frames and the steel structure on top of the 7th floor. does anyone know?
The rendering is abit of an illusion with the shadowing. I dont believe there is a steel structure. That being said, the scale model builder really didnt capture the essence of the darker tones of the brickwork on the king elevation.
