The centre was built by Sir Robert McAlpine and first opened in November 2000. In May 2008, it was acquired by Abu Dhabi National Exhibitions Company. Phase II was completed on 1 May 2010. This expansion created The International Convention Centre London (ICC London) adding to ExCeL's event space, as well as further meeting space and banqueting facilities.
The Royal Victoria Dock closed to commercial traffic in 1981, but it is still accessible to shipping. The centre's waterfront location allows visiting vessels to moor alongside the centre (for example, the 2005 London Boat Show was visited by HMS Sutherland).
The exhibition building itself consists of two column-free, rectangular, subdividable halls of approximately 479,493 square feet (approximately 44,546 m²) each, on either side of a central boulevard containing catering facilities and information points. There are also three sets of function rooms, one overlooking the water, another above the western end of the central boulevard, and the third on the north side of the building. These are used for smaller meetings, seminars, presentations, and corporate hospitality. There are six hotels, more than 30 bars and restaurants, plus 3,700 parking spaces on the campus.
