The new Ronald McDonald House in Rotterdam has been built on terrain of the Erasmus Medical Centre. The available area determined the building’s triangular shape. To fit the complete project in the building’s area, ten storeys have been required.

Prior to construction, several smaller premises of the former Sophia entrance have been demolished while the concrete piles were left intact. A number of adjustments have been made to the preserved foundation of the adjacent clinic.

The new construction’s skeleton has a load-bearing inner cavity leaf on both short edges of the triangle, made out of prefabricated concrete elements. These concrete walls also ensure the building’s stability. The long façade facing the Wytemaweg is for the better part a glass façade. Between the seventh and tenth floor, a steel lattice structure has been applied in two façades to make the cantilevering point possible.

The storey floors are mostly made out of prestressed hollow-core beam floors with reinforced pressure distribution layers, supported by integrated steel beams. On a small number of locations, solid concrete floors have been used. The beams’ load is carried by steel columns that have been coated to ensure the required fire resistance. As a whole, it is founded on concrete beams and pad foundations poured in situ, and prestressed prefabricated concrete piles.
