The colonnade gives access to the
building’s two-storey retail unit, which has
a first floor space that wraps around the
main office reception area which is a large
double-height space.
A second retail unit, which is singlestorey,
opens out directly onto Deansgate.
From second floor upwards the steelwork
is fairly regimented, as the office levels
are all column-free spaces with long
span cellular beams radiating out from
the stability-giving core on three sides to
create spans of up 16m-long. The core is
positioned along the eastern elevation –
towards the back of the building, and so this
fourth side of the building behind the core
only accommodates toilet facilities and a
corridor.
Each floor has primary beams that have
considerable spans of up to 14m in places.
The longest of these members are supported
by two columns positioned just in front of
the core.
In order to keep the office spaces
column-free these two columns will be
concealed within service risers.
Further transfer structures are located
at level 8, to create a step along the north
elevation, and at level 10 to create an
outdoor terrace overlooking Deansgate.
125 Deansgate is scheduled to complete
in mid-2019.
