insulation has been used in an innovative shipping container repurposing project in central Manchester. The project – The OGS Container Scheme – has been built at the Old Granada TV Studios site and uses an array of 20 ft long metal shipping containers to create low cost offi ce space for start-up’s and other small businesses.


The £3m development uses 42 containers to form a four-story integrated block comprising three rows of 14 containers over a ground fl oor podium of steelwork. A blockwork core houses lifts to all fl oors and each level has WC and kitchen facilities and a fl oating walkway with staircases at both ends.


Artez Interiors LTD of Bolton. Artez QS, Jeff Greenwood explains:


Main contractors for the project were “Overall


construction was straightforward with each container being craned into position and locked in place. We used brand new containers rather than recycled so we knew everything would fi t together perfectly.” He continued: “One of our biggest challenges however, was thermal insulation. Metal boxes are notoriously diffi cult to insulate effectively and reaching the required thermal values meant we had to think out of the box.”
