The International Building Exhibition Berlin (German: Internationale Bauausstellung Berlin) (IBA Berlin) was an urban renewal project in West Berlin, Germany. Initiated in 1979, it was completed in 1987, matching the 750th anniversary of the founding of Berlin.[1] The IBA followed two distinct strategies: "careful urban renewal" and "critical reconstruction."[1] With a budget of $1.2 billion, it was to house about 30,000 people in selected areas of West Berlin.[2]
