The design and manufacture of the frame itself was easy, but the challenge to deliver several tonnes of huge pieces of timber to the top of a 14-story building in a busy built up area and with no fixed tower crane, was not. Some of the individual timbers were more than 6m long, weighing nearly half a tonne each.

In collaboration with Fileturn, we calculated that a 300 tonne crane was needed to achieve the 54m height and 66m distance from the building so we called in a specialist crane company. It took 5 hours, 6 operatives and a second crane to attach the flying jib. We only had 2 hours to lift the timber before the crane had to be dismantled. Once on the roof we used a hand operated winch to lift the timber and build the pergola.
