of how the space will be laid out. This formed part of a collaborative design development process with regular reviews to tweak the detail of the design in line with client preference, the URS and compliance requirements.
The new pharmacy Construction of the phase one project began with demolition of internal walls, opening up the space and allowing in natural light thanks to vision panels in the internal walls. This will be transformational for pharmacy staff as some areas of the old pharmacy have no aspect to the outdoors. The internal layout has then been
reconfigured. On entering the suite from the stair or lift lobby, there is a primary change area and locker room. From here staff will enter the facilities via the perimeter corridor, which leads to the outer support room at the far side of the facilities. This is an unclassified office area. From here, pharmacy staff will enter
the Grade D inner support room, a lab area that provides the central hub of the new pharmacy, via a grade D first stage change area. They can then access, two Grade C isolator rooms, via a Grade C second stage change area. To maintain compliance with the required clean room grades, the accommodation has been designed with a pressure cascade of highest pressure in the isolator rooms, lower pressure in the secondary change area and lowest pressure in the inner support room. It was vital that the architectural design was aligned to the required air leakage paths and construction of the facility had to ensure air gaps are controlled in the built asset.
Aseptic suite The phase two project involves remodelling of the existing accommodation to enable effective segregation of the Grade C change and
The new Outer Support Area was created to offer space for users with a splash of colour for user comfort. This is a CNC grade area, finished to high standard with vinyl floors, metal pan ceilings and a hygienic paint finish. Vision panels and pass through hatches have been installed to allow full vision through the facility.
isolator rooms and allow air pressure regimes to be maintained. Access to the aseptic suite will be
by one of two routes: through the new pharmacy outer support room or via the perimeter corridor. A corridor will run through the centre of the suite, with access to the CT preparation facilities on the north side and to the ATMP preparation area on the south. Storerooms and toilet facilities will be
located at the interface between the new chemotherapy aseptic suite and the CT/ATMP aseptic suite. A clog wash, designed specifically for the facilities and the pharmacy team’s gowning protocols, will also be located in this area, as a change of footwear will be required each time a member of staff moves between a Grade D and Grade C area.
The entrance to the ATMP facilities will be at the far end of the central corridor. From the outer support room operatives must pass through a first stage Grade D change area before entering the Grade D inner support room. They must then prepare for access to the Grade C ATMP isolator room in a Grade C change area before being able to enter. Each stage of travel through the ATMP areas is governed by interconnecting air-lock doors, which are controlled on a traffic light system which enables only one door to open at any given time with a visual colour cue to indicate when the magnetic locking system can be opened. An important element of the design
process for the ATMP facilities was to understand the health and safety implications of working with potentially
The vision panels and pass through hatches allow the full view visibility of personnel through each suite of the facility, which is an important safety factor for the hospital.

The newly created Inner Support Area has been designed to take advantage of existing external glazing, while new internal vision panels have been installed to allow full visibility throughout the suite.
