We engaged collaboratively with stakeholders analysing work patterns to develop optimum layout and to reduce distances.

KeyChallengesDue to the complex phasing needs reflecting the ‘live’ working research environment of the building a number of phasingstrategiesweredevelopedandpresentedtotheendusers,potentialexternalcontractors,andconsultantsforfeedback and comment on which strategy would be the most feasible,costeffective,straightforwardtobuild,andcausetheleastdisruptiontothedailyoperationoftheSchoolandFaculty. During the stakeholder consultations five phasing strategies were interrogated reflecting the complex nature of the works.

DesignSolutionThe top floor (level 5) of the building has been opened-up to provide a large, flexible flat-floor teaching spaces for the architecturestudents.Movablescreenshavebeenadded,and a central bulkhead created to provide a service zone, acoustic baffles added to create openness and natural light. Levels 5 and 6 have also been opened up for flexible IT clusters, group offices and larger laboratory spaces.

The team designed bespoke wayfinding graphics and branding for the spaces reflecting thecurriculum.
