Jonathan Smith, Operations Manager at Farnborough International Ltd said:
“The Neptunus Evolution Structure supplied for FIVE (Farnborough International Venues and Events), which has been open since January 2007 has been an ideal choice. The innovative design and excellent insulation properties give the look and feel of a permanent building at a very competitive price; with the added advantage of being fully relocatable. I would have no hesitation in recommending Neptunus and their semi-permanent structures.”
