I think it would be neat to see the Edmonton OmniPlex design using modern technology and materials. As I said, usually these types of things don't serve all sports well, multipurpose stadiums almost never do, but it was a cool concept for the time. I love seeing concepts and designs that never made it. That started for me when they published the finalists for the SkyDome competition in the newspaper. I remember my favourite at the time was the third one (with the blue and red seats) probably because it exposed most of the field.
Pre SkyDome Toronto
In 1985, Toronto launched a design competition for what would eventually become the SkyDome. The 200 designers that entered the competition were narrowed to four with architect Robbie/Allen winning on December 12, 1985 (the first design below). The other three finalists are also shown below. The final SkyDome design differed from these early concepts.
1 RAN International (Robbie/Allen)
2 Webb, Zerafa, Menkes, Housden Partnership Architects
3 Bregman and Hamann Architects
4 Crang & Boake International
