The design and construction project started in 1991 and the building was officially opened in 1996. 
Natural Air Conditioning
Eastgate is considered an architectural marvel as it has no conventional air-conditioning or heating, yet stays regulated year round with dramatically less energy consumption using design methods inspired by indigenous Zimbabwean masonry and the self-cooling mounds of African termites! The natural air conditioning applies to the public walking places inside the mall but to a much lesser extent the actual offices inside, which commonly have air conditioning as they are designed differently based on the partitioning each company chooses. The Eastgate Centre uses less than 10% of the energy of a conventional building its size.  It is estimated that in the first five years alone, the building saved Old Mutual owner $3.5 million in energy costs.
In addition to the termite mounds model, the building was also influenced by Zimbabwe's traditional native stone masonry architecture found at heritages sites like Great Zimbabwe. This is evidenced by Eastgate's heavy masonry walls on the exterior of the building.
The inside design was influenced by industrial machine architecture (steel-lattice girders, walkways suspended on tendons, bridges, and filigreed tiaras) brought in by European immigrants.
