Leeds Council's striking new arena has been crowned with a 7,500sq m Sika Sarnafil single ply roofing system, installed by experienced contractor Lakesmere.

Alongside main contractor BAM Construction and architects Populous, Lakesmere saw the project become its first fully Building Information Modelling (BIM) integrated contract to date, with a collaborative working practice between all teams involved in the project being essential to its successful delivery. Working closely with BAM, Lakesmere devised a specification to satisfy the vision of the extensive design team, as well as providing a practical and economic solution.

With its unique honeycombed external façade and kaleidoscope lighting, the UK’s first 'fan shaped' arena has quickly become one of Yorkshire's most iconic buildings. Opening in September 2013, the 13,500-capacity concert and events venue is set to play an important role in the regeneration of the Claypit Lane area of Leeds, as well as boosting the city's economy through tourism and employment.

Due to the close proximity to residential areas, the Lakesmere team had to overcome a number of environmental and noise considerations when installing the roof. It was vital that the arena's roof adhered to criteria set out in Part E of the Building Regulations. By specifying the S327-18EL Copper Patina Sika Sarnafil system along with suitable insulation for the 7,500sq m main auditorium roof, it was ensured that the arena achieved the desired acoustic performance in terms of noise breakout and sound reverberation.

In keeping with the project's sustainable design, the roof's complex gutter system was installed in Sika Sarnafil S327-15EL Light membrane. A further feature is the installation of a small green roof using the Sarnavert System.
