Please send me a quote for purchase including shipping I want a 7x10x4.6 Meter structure, with three .6x1.2M skylights. It will be an open floor plan except for 1 small room to be used as a bathroom.  I intend to put sliding glass doors on both sides and two windows on each end.  I want this to serve as the second story of an existing stone house so we may need steel pillars and beams to support it so it doesn't rest on the structure of the house on the ground floor.  Time and cost please
