Since the infrastructure is the most important element, the rest of the program is integrated with it as much as possible. In order to create a physical interface, the elevated vacuum tube wraps around itself and descends as a gentle ramp, ending in an airlock that allows for save entry and exits for pods. While the pill shaped loop of the tube forms the exterior façade of the facility, the support structure gets extended towards the interior as a sequence of concrete frames with fileted corners for lateral support.

The pool program is composed of a circuit pool, a diving pool, a play pool and a relaxation pool. The basins are differentiated as pockets along the promenade of the lap pool. Together they form a lake in the landscape, a continuous waterscape that embraces an island in its core. The pool basins are conceived as a concrete relief imbedded in the landscape. The views to the landscape are framed precisely by the façade of the above programs: the monolithic drum compresses the opening down to eye level, controlling views rather than dispersing them.

BIG HQ is BIG’s first example of fully integrated LEAP design – a collaboration between Landscape, Engineering, Architecture and Product designers. Everything from door handles to concrete columns – from urban design to glass facades has been given form by the BIG LEAP team. The building is designed to achieve the Danish sustainability certification, DGNB Gold, through use of FutureCem concrete, which reduces CO

Structurally, the pavilion was a giant self-supporting tubular steel truss, similar to the hull of a steel ship. The external façade structure was the buildings most efficient element. The perforation holes let in daylight and created natural ventilation. It was the only pavilion out of + that did not use mechanical cooling. Due to the structural performance of the truss, the degree of perforation varied with the structural stress along the façade.

To prove that the concept was affordable with standard techniques, BIG decided that nothing would be more convincing than building it in LEGO. It happened that on the : scale model of the building, the size of a single pixel was identical to the size of the smallest one-dot LEGO brick. The model showcased the silhouette that combines the stepped figure of the traditional spire with the rationality and rigour of a functional structure.
