Redevelopment “De Karel” in Amsterdam

In 2015, we purchased the buildings located at Karel du Jardinstraat 61-67. These buildings, which housed the former council building for the Zuid district of Amsterdam, have been vacant for some time now and no longer comply with present-day standards and requirements. The buildings are being redeveloped to house 77 rental apartments with various social/public facilities available in the plinth. The project is divided into two phases: the renovation/redevelopment of the high-rise section and the demolition/construction of the low-rise section.


The building located at Karel du Jardinstraat 61-63 was built by Kuijt in 1920-1921. NV Algemene confectiehandel C&A Brenninkmeijer commissioned the building. The premises were used to manufacture clothing for C&A. Together with Hollandia Kattenburg and Gerzon, the clothing atelier, with over 400 employees, was one of the largest in Amsterdam. In 1976, the building was extended on the east side (number 65) by the architect L. van der Laan from Leiden. The C&A clothing atelier was housed in the building until 1984. From 1987 onwards, the premises housed the district municipal office of Amsterdam South.

Karel du Jardinstraat 61-65 / Phase 1
The integrated environmental permit for phase 1 (high-rise section, number 61-65) is no longer subject to appeal. The first, second, third, and fourth storeys are being transformed into a total of 53 rental apartments in the mid-range segment. The two- and three-room apartments will vary in area between 50 m² and 70 m². The apartments on the front side will have a semi-outdoor area in the form of French balconies. The apartments on the back side will have a balcony or terrace.

“A shared roof garden will be realised on the roof which all residents of the complex may make use of.”

The existing car park will be maintained, providing space for 31 parking spots, an ample bicycle parking area and storage rooms, all of which serve the tenants of the apartments.

The areas on the ground floor are reserved for social/public functions. A definitive list of the ground floor tenants is not yet available, but potential candidates include health and/or sports facilities/services in the form of a physical therapist, pharmacist, or medical practice et cetera.

Façade renovation
The entire façade is being renovated. The brickwork is being repaired, and the plastic window frames are being replaced by aluminium/steel frames containing windows fitted with HR++ glass. The glass fronts that are now part of the façade will be extended down to the floor, and French balconies will be added to the upper storeys.

“The leaded glass on the left side of the façade will be maintained and repaired where necessary.”

The ground floor will become more of an open space, as the façade openings will be combined and also extended down to the floor. The height of the glass upper structure and the upper structure on the right side (number 65) of the building will be increased in connection with the new installations that have to be placed and the lift outflow.

Karel du Jardinstraat 67 / Phase 2
The existing low-rise structure (house number 67) will be demolished and a closed four-storey residential block will be realised with a two-storey car park in the basement. The social function(s) located in the plinth will include 24 rental apartments. The two-room apartments have an area of approximately 57 m² each. The apartments consist of two floors (maisonnettes) and have an outdoor space in the front as well as back (a French balcony in back and a balcony in front). The façade consists of dark brown vertical stone strips interrupted by large glass surfaces in aluminium/steel frames. The roof of the ground floor section as well as the roof of the building itself (see next section) will have sedum roofing and be decorated with three large plant containers. Wooden decking will be placed in the public areas on the ground floor.

The integrated environmental permit for phase 2 has not yet been granted. The permit application is still being processed by the Municipality of Amsterdam.

A thermal storage system will be installed for use in the buildings. This system uses underground thermal energy for heating and cooling the complex. All the apartments will be fitted with floor heating that is connected to the heat pump of the thermal storage system. In the summer, this is used to provide cooling. In anticipation of the new coalition agreement, which specifies that from 2021 onwards new buildings may not be heated with gas, there are no gas connections in the buildings.

Sedum roofing is used over the ground floor section. A sedum roof contributes to improved insulation and serves as a water barrier against precipitation. In addition, solar panels will be installed on part of the roof surface. These will also serve to provide electricity for lighting and for heat pumps. All apartments will have an energy rating of A.
