Henshaw designed, manufactured and installed the new façades to the Premier Oil building at Prime Four. The state-of-the-art 70,000 sq ft office is the company's UK North Sea base.

Aluminium framed curtain walling glazed with a neutral high performance solar control glass with glass  look-a-like spandrel panels was installed to the façade elevations.

The remainder of the façades were constructed using a SFS backing wall system that was clad with the combination of black granite and pressed aluminium rainscreens.
