AerCap House occupies a corner site on Dublin’s St Stephen’s Green. This 5 star property in the commercial centre of the city is a fitting location for AerCap, global leaders in aviation leasing.

Specialist Group combined a wide variety of natural materials in AerCap house to convey an air of classical elegance. Key fit out elements were clad with Kilkenny Limestone, a native Irish Stone which has been used by architects and designers to express their unique vision in some of the world’s most prestigious edifices over the past centuries. Other finishes including walnut, smoked oak veneer, granite, butter colour leather upholstery and stainless steel were all seamlessly integrated. Specialist Glass provided bespoke coloured laminated glass splash-backs incorporated into Joinery elements to give a superior finish to this contemporary office fitout.

Although this was an extensive project that required our work throughout the building, the Amsterdam based Architect, Powerhouse Company had a very particular vision for the central staircase. They wanted to create the impression of a single, twisted piece of wood that spirals through the building from the fifth floor right down to the ground, a sculptural architectural feature with functionality. This was a challenging feat of engineering that required close collaboration with Powerhouse and MAC interiors to both realise the concept and install to the agreed budget and schedule.

After manufacture of the structure the veneering proses was completed entirely by hand. Each leaf of veneer was book matched, hand cut and positioned to accentuate the spectrum of colours in this natural product. The underside of the stairs is particularly complex as it combines a radial pattern and interlinked angles. The application of final finishes to veneer is the most complex element of this process. as it is with this that we achieve the desired finish and display the beauty and colour of these neural timbers.

"The geometry of the staircase, which curved both on plan and section was challenging to engineer. Complexity was also increased by the Architect's request for seamless panel jointing. The manufacturing process involved extensive and highly advanced CNC programming, utilising both our 4 axis and 5 axis CNC machines. "
