Anybody have experience with large outdoor pool/? enclosures? The pool I'm thinking about is 20 x 50 meters. The enclosure would have a permanent roof, need to be 8-10' larger than the pool so that people can walk around it, have double doors to go in and out, have soft sides that can be rolled up or removed in good/warm weather, ventilation capabilty, let light in and ballpark cost.

Has anyone got ideas, tips, experience with these? I've done a Google search, but want to tap the PPOT brain trust.
