The Radio-Pharmaceutical project at the Royal Marsden Hospital involved both a GMP production facility and a research centre for the Institute of Cancer Research. The building is located beside the main entrance to RMH (Sutton) and the steeply sloping site gave the solution.
The production facility is entered at first floor level from the east end of the building while the research facility is entered at ground level from the Westside, and in this way potential conflicts are eliminated by use of the section. As with previous Erigal projects at Keele and Preston the penetration of daylight to the internal workspaces and the removal of excessive solar heatgain was a priority.
In this case a stepped louvred colonade to the south of the building serves to modify and control both light and heat and provides the main architectural expression of the building.
