The Plot 6 & 7 is a 12-storey building situated on the Central Square Site in the Centre of Cardiff. It will serve as the new UK Government Hub building and will be home to 3,500 civil servants in the centre of Cardiff. The principal access will be off Wood Street which will be in constant use in line with a city centre public highway.

The central core includes 8 lifts leading to the main working space on each floor whilst the ground floor includes a café, cycle store and changing facilities with showers to encourage staff to take an alternative means of travel to work.
