Working as a principal with Sports Management in association with ROMA Design, Joel Leider was retained by the Ssang Yong Corporation to program, master plan and design a new sports facilities complex to host the 1999 Winter Asian Games. Leider was responsible for programming, space planning, event planning, sightline analysis and all sports components of the project. Leider also helped produce the computer generated design of the seating bowl and worked with Ove Arup on the structural concept.

The Yong Pyong Sports Complex includes a 6,000 seat Ice Arena and a 5,000 seat outdoor 400 meter Speed Skating Oval. The Ice Arena provides Winter Asian Games facilities for ice hockey, figure skating, ice dancing and short track speed skating and will host other activities such as trade shows, conventions, exhibitions, concerts, and sports events.

The master plan for the entire resort and sports complex will include a championship golf course, a 200-bed hotel, hostel, retail and entertainment village and an International Ceremonies Park.
