The plan ‘de Biezenhof’ is part of the new residential area ‘Waterrijk Woerden’ and is situated along a natural watery region. The urban scheme of ‘Waterrijk Woerden’ was designed by West 8 and refers to the traditional Dutch water cities such as Delft and Leiden. The design is made in collabiation with Klunder architects. Almost every dwelling is individual and has a specific connection to the water.
The plan of Biezenhof is divided in two parts: there is one block of family houses around a courtyard on the edge of the lake, and there is a row of water houses and apartments along a canal.
The buyers of the houses could choose between several types of houses as well as between four architects. Due to the possibilities in combining type and architect, not one house is the same. Every house has a singular character: the lake houses have a beautiful view on the lake, the street houses have a garden, and the canal houses enclose big terraces. In the public space there are a few parking places, the majority of parking places are organised in garages.
The houses designed by Knappers are characteristic because of the huge roof overhanging the façade. This contributes to the shelter-against-the water identity of the houses, and refers to the greenhouse glass constructions in the low lands. At the street side these houses are made of brick, which gives them a closed and open (to the light and the water) individuality.

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.
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.
For the residential house Rapenburg 49 in Leiden, a listed national monument, we designed a plan that both enhances sustainability and strengthens the building’s historical and spatial qualities.
The house consists of a front and rear section. The period rooms in the front house have been restored to their former glory — original details and colors were reinstated, and new wall coverings were applied. The family, with two children, lives in the rear house, which they wished to renovate as sustainably as possible.
By implementing a breathable insulation system, a new insulated ground floor, and an air-source heat pump, the rear house has been successfully taken off the gas grid. During the renovation, the layout was improved, and a dormer and several roof windows were added. The connections on the ground floor between the kitchen and living/dining room, and on the upper floor between the bedroom and library, were reinstated. In all interventions, a careful balance between modern technology and historical awareness was sought.
The project was realized in close collaboration with the client, restoration company Burgy, and Erfgoed Leiden.

The “Villa van Bergenlaan” is located in Rijksdorp, Wassenaar, on the edge of a Natura 2000 protected area.
Situated along a dune ridge, it overlooks the Lentevreugd nature reserve. The villa is modest in expression, partially embedded into the dune, allowing it to become an integral part of the landscape. Energy for the house is generated from sun and air. Because the villa is partly underground, a hybrid structure of concrete and timber has been created.
The materials — including native oak, Fraké wood, concrete, and anodized aluminium — reveal their natural character; nothing is concealed, and in some cases the materials are given a special treatment, such as the wooden slat pattern cast into the concrete. The external façade, one to two storeys high, is clad in timber with concealed window frames.
Characteristic of the villa is the experience of light, space, materiality, and connection with the surrounding landscape. The villa is composed as a sequence of distinct spatial volumes — a modern interpretation of the “Raumplan” principle.
