The conversion of a 1980’s office block to create 6,000 square meters of lettable data hall space, provided space for a plant on a confined site. The design included a six/seven-storey infill block, housing generators and electrical switchgear. Chillers and cooling are housed in a new gantry on the roof. A six metre wide infill building created a challenge in how we introduce the ten metre long generators. The solution was siting the crane in the new smoke vent installed vertically up through the building to lift the generators.
