| Facades
The challenges for the façade design of Building 1 at Paternoster
were two-fold. Firstly, the historic context of the Cathedral and
it’s environs demanded a highly modeled treatment to the façade.
This was achieved through expressing the depth of the primary structure
(white concrete) and that of the tertiary structure of the envelope
(powder coated glazing mullions).
Secondly, space planning requirements asked that, when a typical
floor plate was planned for cellular accommodation, each office
had equal amount of glazed opening in the external wall. This was
achieved though a rigorous analysis and adjustment of the façade.
The building envelope was constrained by St Paul's height restrictions,
Rights of Light to the south and the need to avoid over-shadowing
Amen Court on the west side of Warwick Lane. The design maximized
the size of the building within these constraints. The building
is organized as two ranges of efficient office accommodation, up
to 21m deep, on either side of a stepped atrium.
