Steel Buildings for Recreation?

Steel buildings can fulfill a wide variety of roles - from agricultural and industrial to aeronautical and recreational. While the D-I-Y Shed and Barn pages have been primarily focused on wooden structures in the past, I've been doing an increasing amount of research on steel buildings, of late. I'm particularly interested in the use of steel buildings for indoor soccer facilities.

It takes a substantial structure to house a regulation-sized field. FIFA's laws of the game specify that 50 x 100 yards is the minimum size for a full-sided soccer pitch (for a non-international match). The maximum dimensions for width and length are 100 yards and 130 yards, respectively. Stuffing a soccer field into a steel building is non-trivial, as it requires a structure of considerable size.

Fabric membrane structures present one of the most common alternatives to steel buildings in recreational settings, in terms of the speed and economics of construction. High-end structures of this type look more like works of modern art then circus tents or bubbles.
