Linking to the library's photography gallery on the east side and the main library on the south side, it is hoped the terrace will also be a venue for events, expected to be used by the adjoining Rep Theatre among others.
The owner, steel magnate Leroy Schecter, is combining the units into one large apartment that will have five bedrooms, seven bathrooms, a library, a gallery area and access to some of the best building amenities in the city ( 15 CPW is famous for them).
The exhibition will be displayed in Hengwrt gallery of the National Library in Aberystwyth until the 9 January 2016, and will feature a programme of lectures organised to coincide with the exhibition.
