We settled upon the design with a sheer wall to the east elevation flanking the neighboring building. The wall provides an architectural feature and a base for the service core to stem from. The design maximises the use of space by minimising floor space devoted to circulation in the modest footprint, and allows a highly flexible open plan space with rooms around the perimeter, making best use of light to the North and and West. The south wall has the potential for a double skin facade to regulate solar gain and aid the climate control of the building. By the use of split-level fire curtains to the south stair, the building provides two independent vertical escape routes, allowing the occupant capacity to exceed 60 persons without the need for multiple cores. The sheer wall design also provides structural stability to the concrete frame, minimising the need for interior structural walls and increasing the clear span of the space.

The other layouts focus mainly on atrium spaces which we felt added architectural interest to the building but wasted valuable floor area. We also looked at the possibility of confining circulation to the perimeter of the building but again decided this did not maximise usable area and created an undesirable buffer between the interior spaces and the exterior windows.

1) Specification, Site and Constraints
Main Benefits: -allows light to enter the center of the building -maximises sense of space -flexible space division and circulation -mezzanines suitable for social spaces Main Drawbacks: -high % floor area devoted to circulation -limited occupant capacity for escape lead times -south aspect offices may become oveheated -Reject
2) Central core, no atrium, south perimeter circulation linked to east staircase Main Benefits: -circulation confined to perimeter brise soleil -mezzanines suitable for social spaces -flexible space division Main Drawbacks: -no space for additional escape stairs -circulation divides office space from external windows -high % floor area devoted to cirulation -Reject
3) Central atrium with core, east and west flanking office space Main Benefits: -allows light to enter the center of the building -maximises sense of space -circulation minimised to central walkways -space for multiple vertical escape routes -flexible space division Main Drawbacks: -Void occupies valuable space which could provide core services -Reject
4) Central atrium with two cores, east and west flanking office space Main Benefits: -allows light to enter the center of the building -maximises sense of space -circulation minimised to central walkways -flexible space division -multiple passenger elevators allows increased occupant capacity
