The Challenge

A prominent architectural firm was designing a 70+ story mixed-use skyscraper with complex spatial demands across office, hotel, and retail components. The development team needed to resolve area apportionment calculations for shared service agreements between use components while maximizing leasable space on every floor.

The Solution

Stevenson Systems provided core, shell, and corridor modification recommendations that increased overall rentable area. The team delivered elevator configuration enhancements that improved lease space on each floor and design solutions that reduced the load factor while maintaining rentable square footage.

Using proprietary Space Analysis methodology, SSI provided load factors and rentable/occupiable space calculations supporting marketing and lease negotiations, along with critical apportionment calculations for managing the mixed-use components over time.

The Results

The development team received proprietary market intelligence on competing buildings, including floor dimensions, load factors, bay depths, and core efficiencies. The optimized design increased rentable area per floor while maintaining architectural intent and reducing load factor inefficiencies.
