The most successful aspect of the Deloitte Centre is its relationship to the street outside and the opening up of the Queen Street corner. The enlarged public gathering area is a generous response to the opening on the other side of the road. The project is an example of constraints assisting the architecture. The architects may not have welcomed the retention of the Jean Batten building, yet it has provided a satisfying degree of urban complexity. The materiality of the new tower carefully meets the old condition with sensitive overlaps. The building is consistently detailed with a precise articulation of planes.
