In Wassenaar, 40 duplex houses owned by the housing association St. Willibrordus have been replaced by 86 social rental dwellings, primarily intended for starters and seniors.
The site of the new social housing lies within a village extension from the 1960s. At the time, this was the northernmost district of Wassenaar — spaciously laid out, with views over meadows and farmhouses. In designing the plan for the replacement housing, we built upon the core qualities of the existing neighborhood: generous street profiles, front gardens, and abundant greenery.
The new social housing is distributed across six buildings arranged around a shared courtyard garden. By removing the Stompwijckstraat that previously ran between the plots, space has been created to accommodate residents’ parking within the block, while also allowing room for the communal garden. Along this garden, a community facility has been incorporated.
The buildings feature a formal frontage with so-called ‘zoom dwellings’ on the ground floor — shallow homes with their entrance and a small front garden facing the street. The rear sides adjoin the parking area, which is located beneath an open, green deck. The existing tree structure of the area has been preserved. To ensure privacy for the front gardens, a green strip separates them from the sidewalk. The upper-level homes are accessed via wide external galleries.
The urban design was created by Studio VVKH. To ensure the buildings align in scale with the surrounding structures along the long streets, the façade of the top (third) floor is set back slightly from the building line. The balconies create a connection with the street and are subtly angled to optimize orientation toward the sun. On the northern park side, the buildings are more robust in character, with their height responding to the adjacent apartment block.

On the Boerhaave Campus, part of the Bio Science park in Leiden, the historical anatomy-building has been transformed into housing for Phd-students and researchers of the Leiden University. The new apartments are characterized by their high ceilings and old constructions. A small mezzanine is created to function as a bedroom. Right beside the existing building a new appartmentbuilding is erected, designed by Van Gameren of Mecanoo Architects. The total complex contains 166 apartments and is the first step in the complete transformation of the Boerhaave Campus.
The Plantsoen in Leiden is well known for the historical appearance of both the city park (1836) and the houses of the last quarter of the 19th century. The park was originally landscaped on the edge of the city in the place of an old defense belt. At the entrance of the park at the east side the monumental building Plantsoen 1 – 3 is redeveloped in a complex with 6 apartments. The apartments of about 150 m² are provided with all luxury and comfort, such as a private indoor garage, spacious roof terraces and an elevator, while retaining the historical look and value of the building. Redevelopment also applies to sustainability; obtaining Energy label A. Exterior facades, window frames and roof are additionally insulated. The houses are underfloor heated and solar panels are provided on the roof.
The municipal monument at Plantsoen 1 – 3 is divided over three floors and a basement. The property at number 1 was originally a fully detached house, number 3 was part of a block of 3 houses. Both buildings date from 1875 and were connected in 1957 and converted into one large nursing home. In this function change, the original qualities have largely been lost. The round expansion at number 1 dates from 1993.
In the new layout with 6 apartment, the monuments are restored to their former glory by restoration contractor Burgy from Leiden. The façade of the intermediate building is renewed and aligned with the monuments. The existing façade of the round building is finished with a bronze wall cladding, a ‘veil‘ with a leaf motif. This pattern is inspired by the leaf motifs and decorations of the 19th century, which can still be found in various places along the Plantsoen. The round with ‘veil’ becomes a special recognition point in the inner city.
Each apartment has both rooms in the monumental area as well as in the newer parts. The interior of the monumental buildings is provided with appropriate details to bring back the historical character as much as possible. This specific part is provided by Verlaan & Bouwstra architects from Vianen.
On the inside buyers have a lot of freedom of choice; they can choose for an even richer historical finish with wall tension, panelling and en-suite layout or a tight, modern finish and layout; both are possible. Each apartment is unique, has its own layout and its own character. Only the view is the same for all apartments; they all look out over the beautiful monumental city park the Plantsoen at the town canal.
The redevelopment was completed in July 2018.
The house from the beginning of the 20th century was originally the staff residence of the adjacent main house “Malgre tout”. The main house and staff house are seen as examples of the development of country estates in the municipality. As an ensemble, the buildings and the surrounding gardens are of great cultural-historical value. The ensemble has the status of a national monument. The carefully detailed house is built in red brick under a thatched wolf roof. The staff house originally included a garage, horsestables and a driver's house.
In 2018, a design was made for the restoration and modernization of the service residence including a modern extension. A large living room and kitchen will be realized in the extension. A veranda will be added to the extension. Living room and veranda offer a view of a beautiful Hortensia garden. The extension is completely transparent on the side of the garden. On the other side, the extension is embraced by an openwork masonry wall. The wall becomes more transparent towards the edges. By using a heat pump installation with a source, high-quality insulation, and by completely filling the roof of the extension with solar panels, the service house will soon be completely energy neutral.
In the heart of the Vijfhoek, a picturesque neighborhood in the historic center of Haarlem, stands a large building erected in 1908 by the Waaning company as a factory for Haarlemmer Olie. The building has since been designated a municipal monument. The section facing the Doelstraat originally served a representative function: richly ornamented office spaces were used to receive visitors and convince them of the remarkable qualities of this “miracle oil.” The rear section contained storage and staff quarters, adjoining an inner courtyard with the boiling room, where the sulphur-rich oil was produced a few days each year.
Since the 1980s, the building has been used as a residence. The division between the front and rear sections has been removed, yet the historic atmosphere remains tangible. The new owner asked us to develop a plan to prepare the entire building for a new century—energy-efficient, comfortable, and focused on the enjoyment of living, both along the street and around the inner garden. The boarded-up garage doors have been replaced with generous glazed folding doors. Using flax insulation, the building is insulated from within; new glazing is installed, and the roof is insulated from the outside. Heat pumps and solar panels provide sustainable energy generation. In close consultation with the Heritage Department, all characteristic elements are preserved—allowing the new residents to begin the next chapter in the rich history of this building.
In close collaboration with restoration contractor Burgy, EPOS Advies, and energy consultancy Kroon, a plan of approach was developed. Construction began in February 2024.
