ONE ON ONE office building

Situated in a complex urban corner site in the heart of Luxembourg-City, One on One’s architecture consists of superimposed skewed volumes of glass and metal. This resourceful optimisation of internal space offers high flexibility for accommodating open-plan or partitioned offices. One on One is BREEAM “Excellent" certified. One on One was awarded the Luxembourgish "Bauhärepräis 2016" in the “Administrative and office buildings” category.

“Despite the complex urban situation, the challenge was to create the maximum amount of office space while ensuring maximum flexibility. We used all tricks and knowledge to transform constraints into strengths and strong architectural elements. This resulted in designing a building where glass cubes stack and shift, creating private terraces along the building’s inwardfacing edges. The clever positioning of the central traffic core frees up generous peripheral areas that offer perfect size and shape for flexible office layouts. Finally, this building is seemingly created from the simple idea of stacking office cubes but in fact it is the product of a multitude of constraints and the combination of vital elements. The spectacular restructuring of this corner site’s volumes has resulted in the creation of a premium address on Route d’Esch which offers its users impressive, easily arranged office spaces.” Stefano MORENO, achitect

The challenge to sustain the overhanging volumes without perturbing inner columns behind the facade needed a flexible and lightly system. Therefore, the upper structure is realised in steel, founded on a concrete basement. The shape of steel-frames is following the movement of the superposed volumes, organised in a 1.25m-grid and stuck together by collaborating concrete-slabs without the need of visible lintels. At the end, the structural concept is the key for maximum flexible and natural-lighted office layouts. The isolated cladding is composed by a combination of a triple-glass curtain-wall system and traditional isolated metallic boxes. The exterior double-skin is provided by high performed solar glass and offers an efficient solar protection while the offices benefits of daylight, reflected by inner stores. A double-floor system and active ceilings sustains the great flexibility of the offices.
