Ron Arad Architects has completed this 19 million euro (£17 million) shopping centre within the 40,000m2 Médiacité development in Liège, Belgium
The 350m-long, weaving mall links the recently refurbished ‘old market’ to the new national television centre through a two-storey building. The lattice steel roof of the mall, described as ‘a deformed grid-like network’, is entirely free-spanning along its length and width.
This roof is made from 200mm-wide steel ribs, varying in depth from 1.2m to 300mm.
Explaining the structure, a spokesman for the London-based practice said: ‘To minimise loadings the complex three dimensional form is clad in transparent lightweight ETFE pillows – pneumatic Teflon cushions which allow light to penetrate the roof while moulding themselves to the irregular structure.
‘As the roof gradually transforms into facade the ETFE cladding merges into curved aluminium rain-screen panels and glass.’
Built to a ‘highly accelerated programme’, the project took just 34 months from ‘inception (April 2007) to completion’.
The total built area for the mall is 9,750m² and was delivered for €1,920 per m² (£1,655 per m²) .
