The Union Square
project involved the creation of twelve sets of stainless
steel and glass stairs for a luxury apartment complex.
The design that was brought to CMG, which was created
by the building’s architect, featured stairs
that were nearly seamless. The challenge in this design
for CMG was creating a staircase that was made of
steel and was counter leaver from the wall –
the stairways did not have a stringer. In addition,
the glass railings were to be flawless in appearance
– the client did not want any bolts or nuts
to be visible.
To address this design challenge,
CMG created a structure where the steel members were
hidden in the wall. Heavy-duty laser cut plates were
connected to these hidden steel members, which were
marked and connected to the standoff that held the stairs.
The stairs were designed with laser-cut stainless steel
and computerized bending with a tolerance of 132. The
glass railing was made from half-inch tempered glass
with computerized CNC for accuracy.
