  • A showcase for the NHS as a whole;  as political, in its way, as Lubetkin’s Finsbury Health Centre    
  • Avanti’s facade is a restrained composition    
  • Finished in render, timber, glass and reconstituted stone    
  • Main Entrance defined by an acute canopy confined by the restraints of the site    
  • The reception area resembles the point of entry to a stylish hotel    
  • A top-lit north-south street runs the length of the building    
  • The clarity of the building is aided by  a refeshing sparsity  of notices     
  • An open court in the E-shaped patient zone    
  • Site plan    
  • Ground floor plan    
  • First floor plan    
  • section    
  • Detail of facade with tapered eaves, string course and cedar panels    

Rapid diagnosis centre using X-ray and other 'imaging' techniques, such as scanners and ultrasound designed using people/process mapping software

The overall triangular form of the building closely follows the confines of the site. A Top-lit 9m high galleria, which is crossed by a series of bridges, with some modest gestures toward modern roots, is the public core of the centre.

To the west of this public zone, are two floors of imaging and 'intervention' (operating) facilities, topped by a layer of services. To the east, the E-shaped 'patient zone', formed around two open courts, includes reception areas, consulting and treatment rooms and a recovery area where people can sleep off the effects of anaesthesia.

The floor structure was designed for the future flexibility needed in a hospital building including heavy blockwork, void formers within wide beams for future service penetrations, and potential breaking out of structure between ribs for services.

The ACAD building has a large ventilation and air-conditioning system flexible enough to be adaptable to changing needs within the hospital and care practice generally. It provides a high level of environmental comfort for both staff and patients.
