Connolly Station Annex
A multi-storey glazed annex beside Dublin's Connolly Station — ≈46 tonnes of steel detailed around Macalloy bracing, a lift shaft and stair core.
The Connolly Station Annex is a compact, fully glazed multi-storey structure: a steel 'glass box' frame threaded with Macalloy bracing, a lift shaft and stair core, a top-floor maintenance platform for lift servicing, roof-access steelwork into the existing building and an external elevated access platform.
The detailing challenge was space. Connections had to be designed within a tight structural layout, the stair arrangement had to stay fully compliant inside a restricted footprint, and the Macalloy bracing demanded exact fabrication tolerances.
Because the façade is fully glazed, the steel model was continuously coordinated with the curtain-walling contractor in BIM — every interface between frame and glazing resolved before fabrication, which is why the erection sequence ran smoothly on site.
Outcome
Efficient on-site assembly with minimal installation issues — a contemporary glass box that sits comfortably against the historic station.
