Station Design on Segment G

I've started to work on the station building design. It's taken me an absolute age to decide on the final design because I couldn't figure out in my head how the building would interface with the platforms and track.

So in the end I decided to build a 2nd bridge, rather wide, and place the building on top of it with stairs leading down to each platform. 

Here is the facade which sits on the bridge and over the track.

Starting to take some form.

The next step was to figure out how to do the stairs down to each platform.

I took some inspiration off Wembley Central tube station and came up with this:

The next step was the roof. I wanted something that had some 3D relief and didn't look too flat and bland. The laser cutter really helps in this situation to make the trim under the roof.

That's it for now. The next step is the apex of the roof and then finally the detailing.
