Innovative steel transfer solution to resolve complex station constraints and maximise usable hotel space
Little National Hotel is a unique and innovative steel transfer structure nestled within hotel walls maximising useable hotel space and resolving the complex Wynyard station constraints below. The $50 million project is currently under construction and taking over the airspace above the Clarence street entry to Wynyard Walk and Wynyard train station.
The distinctive building will feature a lightweight composite steel frame with bondek slabs to enable 10 levels of hotels rooms, a reception level, gym, library, and an exclusive rooftop terrace bar.
For this busy CBD live environment many unique and innovative design and delivery processes are being utilised:
- A steel frame designed in parts for easy transport via shipping containers and simple install on-site to assist with the site restrictions.
- A tower crane has been fixed to the roof of the existing structure to enable the site to operate with minimal impact on Clarence Street and the train station entry below.
- Cantilevering steel fire stair.
- Portal frame Green wall off the Eastern facade.
- Reticulation of services through custom steel beams to resolve tight floor to floor clearances.
- Custom fabricated sections utilised to minimise structural widths and enable desired architectural set out to be achieved.
- Rooftop to have custom architectural steel framing to the terrace lounge areas with concealed façade framing within the steel profiles.
A multi-storey steel truss has been utilised to transfer the loads from the upper levels down, bridging across the open reception level to the existing structural concrete columns below.
