Platform on new construction, renovation, restoration and transformation
The renovated national monument now consists of villas and apartments on a so-called villa park. Formerly a psychiatric hospital, the national monument now houses 29 villas, 4 apartments and a theater chapel. The houses were given floor areas of 220 to 500 m2 and were delivered as shells. The building stood empty for twenty years and will go on to be known as the Carré of Bloemendaal.
For this project, it was important to improve the foundation and restore the properties. The renovation for the houses was mainly in renovating the facade cladding and roof, the installation of residential separating walls and the installation of thermal and acoustic insulation. First, the floors on the ground were taken out. Then about five hundred screw injection piles were installed. Boxed in between the existing walls, the new concrete floor was poured on this. The residential partition walls were prefabricated. These are composed of ceramic blocks. The walls were put in place with the help of a crane via the roof. The urban villas realized in the existing building all have three residential floors and in some cases an attic floor. The residential floors have a height of as much as 6 meters.
The roof elements came from Unilin, involving a total of 3,500 m2 of single-shell roof elements. In addition, they wanted to bring back the look of the old scrap ceiling. This was achieved by pre-plastering them on the underside with planed and plowed pine sections. Because these were old buildings, it was not always possible to use standard sizes. Therefore, it was sometimes necessary to "think the other way around. Fortunately, no roofing element was delivered incorrectly on this project.
The villa park takes its name from the square shape in which it was built at the time. It covers no less than sixteen thousand square meters and borders the South-Kennemerland National Park. The stately style in which the original building was constructed was a deliberate choice. It had to exude medical authority to keep the psychiatric patients, the insane as they were then called, in check. The authentic facade has remained intact, as has the characteristic chimney on the enclosed middle grounds. To bring back the authentic character of the roofing also as much as possible, the existing roof tiles have been reused. It is an impressive transformation project that does not fail to impress. Meanwhile, the Carré of Bloemendaal completely transformed into a villa park.
