Where we started

Minimalist design meets trailblazing technology at this brand new building to create a welcoming space to showcase the work of an important science hub. The Institut Laue-Langevin is a pan-European initiative providing neutrons to visiting researchers for experiments and analysis at the molecular level. Our work at the Institute includes a new visitor centre which will give access to the institute’s array of state-of-the-art equipment and provide scientists with a base for their work. Alongside this, we have also designed new multipurpose conference facilities, bookable lab space and healthcare support.

The minimalist design came from the client's team of scientists who wanted a calming, pared-down and elegant interior

The perforated façade and clerestory windows provide the scientists with light and privacy

A helical concrete staircase connects the two floors whilst acting as a sculptural centrepiece

Workspaces are punctuated by a steady rhythm of vertical openings to offer views out and plenty of natural light

The sleek white exterior is set against the striking backdrop of the Alps

The new building has completely changed the way we welcome our visitors and employees when they arrive at ILL. The new space is expansive and bright, creating a contemporary and gentle atmosphere.

Institut Laue-Langevin representative

We won the original visitor centre design competition in collaboration with TKMT architectes who are based in Grenoble. This partnership reflects the international boundary-crossing efforts of the Institute itself, which is largely backed by the UK, France and Germany.

With scientists forming the client group, even small changes could have a large impact on how the occupants could use various spaces. We therefore rigorously explored every material and detail decision in close collaboration with them.


The design combines an exposed concrete structure with a lightweight, perforated metal skin

Conceived in two halves, the centre is split into public and private zones to balance accessibility with more secure functions. The new building has a delicate appearance, underpinned by a solid, muscular structure. Slender white perforated fins on the exterior modulate daylight and privacy and are arranged in a lenticular pattern inspired by the process of neutron diffraction. The fins alter the appearance of the façade, from morning to evening, during different weather conditions and when viewed from alternative angles. A singular skylight pushes its way through the roof of the building to provide natural light throughout the space.

Axonometric drawing of the new visitor centre

The interiors are crisp, white and calm, featuring elements of timber joinery to offer moments of warmth and texture. A large helical exposed concrete stair rises from the ground to the upper level, which is set in a double-height space with a floor-to-ceiling window. The staircase becomes a sculptural object when viewed from the outside and reveals the life and activity within the building as people move through each level day and night.

Raw concrete blends with bespoke timber cabinetry and crisp white surfaces

We have designed a calm and elegant base to showcase the Institute’s innovative work, sitting in contrast to the dramatic skyline of the Alps, which can be viewed by visitors as they move around each new space.
