In cooperation with Smits bouwbedrijf, VVKH has won the european tender to develop a new housingarea in district Dieperhout in 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 aluminiumreveal 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.

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.

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 gloryoriginal 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.

Middelsee is the expansion plan on the southwest side of Leeuwarden, based on an urban design by West 8. The Frisian water city serves as a source of inspiration. Commissioned by the smallest housing association in the Netherlands, we have designed a plan for homes arranged around two green courtyards. It forms a small-scale community with plenty of space for encounters, and a robust waterfront with the apartment building as its eye-catcher.

Using simple means, variety is created so that no more than two houses are ever the same. The foundation remains consistent: a compact floor plan, lightly jointed red brickwork, and solid white window frames. We introduce variation through a dormer or a brick roof extension, a roof edge detail, or a distinctive entrance feature. The client’s existing housing stock in Leeuwarden’s city center also served as inspiration — a characteristic working-class neighborhood with abundant greenery.

In our plan, residents meet each other around private stoops and gardens bordered by low hedges, as well as along the wide galleries on the timber façade of the apartment building. Shared bicycle storage areas and shared cars also contribute to the sense of community.
