Camden Lock London Ltd gained planning permission for a new market building in Spring 2011. The new building consists of steel arch construction which is clad in both ETFE fabric and lightweight plastic panelling. The arch structure spans some 40 to 50 metres and also encompasses a mezzanine level to significantly increase the number of stalls and provide protection against inclement weather.
The location of the new market building is adjacent to Camden Town tube station and there are London Underground tunnels beneath the site. In addition there are also historic deep level bomb shelters in addition to the tube tunnels. Camden Town tube station is a major deep level station and the crown of the tunnels are some ten to fifteen metres below ground level. The new foundations will be founded at high level with a formation in natural material thus the increase in loads will not be significant by the time they have spread through the clays above the tunnels.
