A beautiful old beast.
But the costs are beyond massive.
When built, airconditioning was just invented.
Typewriters were human powered.
All the building services will have to be substantially increased for current and future needs.
Where do you place them? Fire protection, how do you install a sprinkler in a herringbone ceiling? At what cost?
Many engineers and architects with sharp pencils can overcome huge problems.
Half a million sq ft (usable?) 200 sq ft per person?
WHERE WILL THEY PARK THEIR CARS?
Parking can equal floor space.
They need a TEN ACRE PARKING LOT OR LARGER!
And access roads, fire lanes...
Detroit, home of the car.
