Dupont™ Corian® Lights Up The Architectural Face Of The City Of London Taking the place of a run-down office building in the heart of the City of London, the striking new “Motel One” building by “Mackay + Partners” features ground-breaking use of DuPont™ Corian® high-tech surface as an illuminated façade. The first commercial building in the UK to adopt this exciting application for the renowned DuPont advanced surface, the structure presents a sparkling new face to the heart of the financial district, set within the historic Minories neighbourhood. Offering a welcome new four star facility to the area, the latest Motel One operation hosts 291 bedrooms and is now open for business. The building comprises two forms: a seven storey “decorative cube” fronting the street and a sixteen storey glass tower to the rear. Designed by Mackay + Partners for developers Endurance Land & Scottish Widows Investment Partnership, it brings a bright and a fresh new identity and a directional aesthetic vision to the area. The concept enjoyed full support from the City of London planning department who were happy to explore the choice of DuPont™ Corian® as the exterior cladding material, as opposed to the more typical specifications of steel, glass or stone. “The design is entirely contemporary, yet fully responsive to its current and known future context,” says Ken Mackay of Mackay + Partners, “I have specified DuPont™ Corian® for other applications and so I am well aware of its properties, but the choice of Corian® to clad this project came about through extensive research and working very closely with DuPont.” This elegant exterior skin for the new building functions both as a sustainable open-jointed rain screen façade and also as a distinctive design feature. The eye-catching cladding, made from DuPont™ Corian® in a translucent white, presents a pure and simple finish during daylight hours, but at night, backlit designs within certain panels illuminate the structure to dramatic effect. The LED lighting system is on a colour wheel that can be changed via computer controlled dimming and the patterns and hues chosen reflect the Motel One brand. This combination of rain screen

cladding with LED lighting is a first for London, according to the architects. The exterior cladding was created using approximately 1000 square metres of DuPont™ Corian® high-tech surface in a 12mm thickness and by exploiting the brand’s unique 1500mm width sheet to reduce the necessity for additional joints. The facade system was installed by specialists Silverside Trading of Shoreham-by-Sea in Sussex. Mackay + Partners ensured a high standard of sustainability in all aspects of the development, which has achieved a BREEAM excellent energy rating. Key to this was the design of a façade with excellent thermal performance (and just 35% glazing) plus the specification of heat recovery systems and green roofs to further enhance efficiency and mitigate rainwater run-off. DuPont™ Corian® is proving to be a valuable solution for façade applications in many ways, from design versatility to long term functionality. Completely homogenous and non-porous, it is easy to clean and maintain. It is also fire rated, resistant to graffiti, UV and climatic conditions – and should any damage occur – the material is repairable. DuPont™ Corian® is compatible with a ‘secret’ fix undercut anchor system and its lightweight, workable properties are a further benefit to both fabrication and installation. DuPont™ Corian® also offers the broadest range of international certification for facade applications among solid surfaces and has passed a series of fundamental tests for its application to the exterior of buildings. These include freeze/thaw cycling resistance, standards proving the material’s resistance to exterior environmental substances, fire performance tests, and tests for abuse resistance. Further information and certificates are available on request from DuPont. www.corian.co.uk ENQUIRY 110
