Robb's buildings were subsequently demolished opening the way for construction to begin on the Rialto.

Designed by architects Gerard de Preu and Partners in association with Perrott Lyon Mathieson, the building was built between 1982 and 1986, opening in October 1986, and takes its name from the much older Rialto Building next door.
The massive glass curtain wall façade of reinforced blue tinted mirrored glass is its central feature and changes colour during the day, ranging from a trademark dark blue to a brilliant gold during sunset.

It is 251 m (823 ft) high, with 55 floors and 3 basement floors.
It comprises two conjoined towers, the shorter North Tower being 185 m (607 ft) high with 43 floors.
In total, there are 84,000 m² (900,000 sq ft) of office space.

Early tenants moved into the lower floors while the upper floors were still under construction in 1984.
