The AC Hotel by Marriott, at Belfast’s City Quays, brings together a suite of systems from architectural aluminium company Metal Technology.
Part of a mixed-use regeneration project by Belfast Harbour, the four-star hotel rises nine storeys and includes 188 bedrooms, reception area, lounge and bar, gym and meeting rooms. The glazed façade is constructed using Metal Technology’s System 17 curtain walling, capped and silicone pointed, complemented with System 4-35Hi+ casement windows and System 5-20DHi+ doors from the THERMAL range. It is also one of the biggest commercial projects to incorporate the newest product on the Metal Technology family, System 26Hi+ bi-fold doors.
This is the first AC Hotel by Marriott on the island of Ireland and features “Novelli at City Quays” where multi-Michelin-starred chef Jean-Christophe Novelli adds his flare to the dining experience.
Used in isolation or in an integrated scheme, Metal Technology systems provide reliable structural integrity, weather performance, thermal enhancement and security, together with creative and design freedom to deliver superb results, as evidenced by this stunning hotel project.
