You can add a partial loft (not complete), however it will not double the square footage. Due to the sloping side of the arches that make up the structure on the MAS-1300™ it is not possible to use all the floor space of a 2nd floor deck system. A 2nd floor deck system that covers approximately 1/3 the foot print of the MAS-1300™ structure will only give a usable area of approximately 200 to 250 square feet.
You can NOT add a deck that spans from wall to wall due to thermal expansion limitations. MAS™ only recommends the use of a 2nd floor decking system for storage or situations where personnel need to be located above other works for strategic reasons.
It is more cost effective to attach a MAS-570™ to the MAS-1300™ to create additional square footage then it is to install a 2nd floor deck system.
