A transformed 1970’s office block at One Mabledon Place in central London has been reborn as ‘The Halo Building’, with the addition of a distinctive roof screening solution, from Levolux.

The Halo Building1 200 x 200The 80,000 sq ft, eleven-storey office building, which is attached to a five-storey annex building, was originally home to the trade union Unison. Following a multi-million pound refurbishment  project  it  has  been completely  refurbished  inside  and  out, including alterations to its existing façade and extensive roof level works.

Located on one of London’s busiest high streets and designed to achieve a BREEAM ‘excellent’ rating by Bennetts Associates, the project demanded meticulous planning and a collaborative approach, particularly when it came to delivering the highly visible roof screening solution.

The Halo Building2 200 x 200As the UK’s leading solar shading and screening specialist, Levolux was chosen to, supply and install a custom screening solution, comprising vertical mesh panels, topped by extruded aluminium Aerofoil Fins, arranged into horizontal panels.

In total, Levolux installed 244m2 of fixed, vertical mesh panels, measuring 2.3 metres high, extending around the perimeter of the roof. The vertical panels are designed to screen unsightly plant and equipment from view. Each panel is formed from galvanised steel for long lasting good looks and features rectangular perforations measuring 76mm by 25mm.

The Halo Building3 200 x 200Above the vertical mesh panels are 62 horizontal panels incorporating 12 Aerofoil Fins. Each Fin measures 100mm deep by 23mm thick, and is fixed between aluminium side plates. The horizontal panels are fitted within a steel frame by others, allowing them to project 1.9 metres out across a perimeter walkway and an outer balustrade, extending past the building’s external envelope.

The horizontal panels are divided into two continuous sections which are faceted to follow the building’s curved façade at roof level.

All aluminium components, such as the Aerofoil Fins and side plates, have been given a highly durable and attractive green brown metallic, powder-coated finish.

The Halo Building4 200 x 200By combining vertical mesh panels and horizontal Aerofoil Fins, Levolux has succeeded in screening unsightly structures at roof level, while creating a distinctive architectural feature that resembles a ‘halo’. This projecting structure is attractive during the day and becomes even more striking at night when it is illuminated.

With this in mind, it seems very appropriate that developers Stanhope chose to present the refurbished office development at One Mabledon Place, to the city as ‘The Halo Building’.
