» KAWNEER ’ S AA ® 265 unitised system was adapted by the company for the commercial element of the £ 200 million Atlas building - at 40 storeys the tallest tower in London ’ s Tech City area - at 145 City Road , Clerkenwell .
Concept-designed by Make architects and delivered by the Design Delivery Unit of Scott Brownrigg , the commercial building actually featured a total of three types of Kawneer ’ s curtain walling – the traditional stick system AA ® 110 ( zone drained ) on the ground floor , the adapted AA ® 265 on the floors above , and standard unitised AA ® 201 on the tenth floor return elevation to the existing building .
The adapted AA ® 265 modular system incorporated GRC and
|
aluminium rainscreen cladding and glazed vision areas in each panel . Some 3m wide , 3.85m high and one tonne in weight , each unit was delivered to site and hoisted into position by a tower crane , complete with the cladding and glazing in place .
The Atlas ’ commercial element is occupied by WeWork ; allowing members to enjoy 11 floors of collaborative work spaces , stunning private offices , welcoming event spaces , and modern conference rooms for hosting key client meetings .
Along with the Atlas tower , the WeWork building sits above the London Underground and Thameslink lines . This discovery at planning stage changed the concept for the structural strategy , resulting in the creation of a new
|
superstructure design to prevent the buildings from twisting and leaning .
Design Delivery Unit at Scott Brownrigg demonstrated options that could be achieved using anodised aluminium , and following modelling and testing of the material , proved that given the scale , repetition and shape of the facade , a unitised system would work and still achieve the original vision ; a series of white and off-white shades of terracotta cladding . However , with the stability issues raised at post-planning , the weight of the terracotta posed a challenge with the cantilevered building .
Loads imposed by the buildings are kept clear of the tube tunnels by cantilevering the structures over the subterranean Victorian
|
engineering . The mass provided by the frame , and by increasing the thickness of the groundfloor and mezzanine first-floor slabs , helped give the structure sufficient inertia to dampen the ground-borne vibration from the underground trains .
