« THE ULTIMATE BUILDING is situated in the heart of Luxembourg-City, nearby the railroad station, and in consequence one of the first and quite remarkable locations to see entering Luxembourg-City by train.
The project was named « THE ULTIMATE BUILDING », because it is situated on the old city border of Luxembourg.
In former times a border guard was to be found in that place. 
THE ULTIMATE BUILDING is filling the gap on a plot with a high potential in user surface, that has been left idle for many years in the past.
A special shape, that perfectly matches the plot and sustainability meet up in this inimitable project.
The surfaces in aluminium, the wooden structure and the composite panels reflect the durability, the elegance and the vitality of the building.
Its organic form and its architectural design make THE ULTIMATE BUILDING a unique place to be with a strong identity. »
