I am looking for roof space to lease for a negotiable number of years.
I would like to use this roof space as a place for my 6.5 square meter micro compact home, and a machine making water from the air with a profile of (Height x Width x Depth)  119 centimeters x 72 centimeters x 76 centimeters, weighing 120.0 kilograms.
This website (  http://www.microcompacthome.com/company/  ) has more information about the modular home i will be having on your roof. 
I am willing to negotiate a price for your roof space, space that you probably don't use at the moment, but that could be making you a little extra money.
