NACWL were employed by Galliford Try to supply and install the facade envelope system to 13 floors of the new HMRC building, located in the center of Birmingham’s regeneration scheme. The building has a striking honeycomb facade, formed from 1,521 hexagonal panels, which change the appearance of it according to the time of day, weather, and seasons. The building will see around 3,600 public servants, from various government departments, move in later in 2021.


NACWL used the Schueco FWS50 curtain wall to create a completed wall lining system for the main facade, spanning the full height of the building. The curtain wall included clear double-glazed units, metal spandrel panels, and acid-etched translucent units. The curtain wall and metal glazed spandrels acted as a supporting structure for the decorative, anodised aluminium rain screen to hang from.
These unique hexagon panels were pre-treated differently so that the right-hand panel had a different finish than its adjacent left-hand panel. This was a particularly difficult process as the natural process of anodising is hard to control, but the result was a fantastic multi-tone effect that gives the facade a striking look.

Above each vision area of glazing was the feature eyebrow. This was designed to accept a potential access load which required highly engineered Brise Soleil brackets and internal carcass frame reinforcement to ensure loads could be accepted. This structure was then clad in a PPC aluminium tapered fabrication, giving a unique contrast against the bright anodised panels, framing the vision area.

To the ground floor level, large double height curtain wall screens were constructed from Schueco FWS50 SG silicone jointed curtain wall, leaving a seamless glazed facade.
