St. Mary’s Cathedral forms a major landmark on the west side of Edinburgh’s New Town and, in combination with the Chapterhouse, Old Coates House and the Music School, forms an inter-linked series of Listed Buildings and courtyard spaces located within a simple setting of informal lawns flanked by peripheral lines of mature trees. The Cathedral Board propose to introduce a new Medical Centre to meet local needs into this sensitive location, which would create two new distinct courtyard spaces, each of which would have different functions. The northern courtyard forms the main pedestrian entrance and focuses around the existing Memorial Cherry tree, which the new building has deliberately embraced. Geometry and detailing is simple and precise to reinforce the importance of the adjacent buildings. To the south, a modest gravel-dressed surface forms a parking court, drop off zone and secondary entrance, focused around a central specimen tree.
