After designing a couple commercial buildings I wanted to start designing some details for the rooftops and sides of the buildings that wouldn't be building specific. I came up with a freelance design for a cooling system to go on the rooftop. The first is this 4' x 4' x 4' smaller swamp cooler that would represent pre-air conditioning systems. These pictures were taken close to the building with a wide angle lens so things are out of proportion size wise. This is a small building though at only about 800 sq. ft. (25' x 32'). There are 4 options for printing it and you can also print the pieces above and cut and paste them to modify the duct-work as needed.

Those are the kinds of details that really make a structure "pop" in my opinion. These look great! Mike
