Dominion House was a 6000m2 empty office block in Cardiff City Centre. Purchased in 2015 to become a 100-bedroom hotel with rooftop Marco Pierre White Steakhouse Bar & Grill, this development is soon to be named Indigo Hotel. Global hotelier, Hotel Indigo, currently operates 60 hotels worldwide.

CMB Engineering Cardiff Limited, the Building Services Contractors working on the project, chose Pump House on the day to supply all the rooftop building services support frameworks.

Supplied via BSS in Cardiff, our hot dip galvanised frameworks were specifically supplied in lengths and widths to suit each unit being supported. With all products being available from stock, the contractor could order frameworks in stages, to suit the phased project programme, and eliminated having to find space within an already restricted working environment for everything to be delivered at once.

With a fast installation time, all frameworks could be assembled quickly, even on the morning of the crane lift! All support frames come complete with adjustable legs incorporating M24 height adjusters to enable the installer to level the frameworks against typical flat roof falls.
