from the sketch you show, i am guessing this is a commercial condo structure with setup for office in front and warehouse in the back.

They only have 220V 200A service typically.  And it's not as simple as upgrading the panel.  You need new wires from the transformer, if the transformer has capacity (it probably doesn't).

You will be hard pressed to support the cooling requirements in a space like that.  Even if you have a climate that allows for only air cooling year round, 200 kw calls for around 30 000 CFM of air in an ideal situation (100% efficiency and separation between hot and cold)

Even running 20 kw in that kind of space would be challenging.
