In the early 1930s, Lunding drew up the plans for the underground reservoir system that supplies water to the city of Copenhagen. Construction went on for several decades until the ten reservoirs that still exist today were completed.
Even if this urban infrastructure was largely underground, Lunding approached the project with care, globally and in the details, in the visible aspects and in the parts that would remain hidden. The design drawings are precise in their attention to the architectural details but also in the design of valves and pipe systems, and they stand out as a beautiful example of functionalism.
When construction on the reservoir began, the use of reinforced concrete in Denmark was restricted by law to industrial architecture. Lunding took advantage of the situation as an opportunity to exhibit the material’s expressive possibilities. A beautiful example of the refinement in the details can be seen in the access points: small parabolic domes that combine concrete, steel and copper, which periodically dot the enormous surface of the Tinghøj reservoir.
