I have attached the photos showing the sleepers built up for the barat the O2 @Dome.
Stephen Cromwell Bedford & Havenhand Shopfitting Ltd
Great photos showing the manufacturing of a huge installation by shop fitters. The total bar / desk seems to weigh about 3 tons or more ! Clearly a massively chunky, rustic piece of furniture that could only be designed by architects ! The mobile phone stand looks great !
Have a look if you're in the London Dome.
