Having had read about this place I couldn't resist visiting it today.
Only two carriages are visible from the street but those are actually "the top floor" - there are two more of them lower on the roof...

Besides the coaches there is enough space on the roof to accommodate a bike rack, a barbecue and several benches making a nice recreational area with a view combining design and decay so typical for Shoreditch. Containers serving as a basis for top carriages are also habitable.
On the top floor:
I asked if the driver's place is usually occupied by boss - alas, nothing is perfect. Still, these two seats are used for job interviews:
I don't actually know if this is really a good place to work in (I'm seriously concerned about the hot weather - with no AC or opening windows the iron carriage would quickly turn into an oven) - but still the idea is definitely worth a visit.
As the Open House Weekend continues, visiting another location is on our plan for tomorrow.
