The replacement of architectural features will be historically accurate and appropriate to the building, based on physical evidence on site and replication of existing historic profiles. Restoration work will be carried out using materials which are appropriate to the original building, and constitute the minimal intervention necessary to consolidate the historic fabric. The proposed extension sits within the courtyard formed between the C shaped plan of the existing convent building to the South, east and West and the Chapel to the North. The extension is conceived to meet the requirement for a communal space as part of the proposals within which the organisation can gather staff and host gathering in connection with the operation of their business. As part of the extension alterations will be carried to a rear return currently housing a secondary staircase to enable a compliant fire stair to be extended to the attic. Within the courtyard adjacent to the rear return will be an external lift shaft and service riser. The extension, stair core and lift shaft have been designed congruently to provide level access to the extension and mezzanine.
