The “Meerwijk” district in Schalkwijk, built in the 1960s, has been built on the corner of Bernadottelaan and Albert Schweizerlaan. This center is part of the urban design that was made by our office in 2001. The building with retail spaces, including the Vomar supermarket, an underground parking garage with 215 places and 74 apartments, is one of the sub-plans of the community center. The whole has a modern, transparent and friendly character and adapts well to the neighborhood.

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.

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 close consultation with the municipality of Leiden, VVKH has developed an urban development plan for the redevelopment of two office buildings on Verbeekstraat in Leiden. What is currently a densely populated area dominated by cars will soon become a vibrant, green, and people-friendly residential area. In line with the municipality's high-rise vision, several buildings will be added along Plesmanlaan, creating a new cityscape along this access road to the city. Together with the developments at the Bio Science Campus on the opposite side of the road, this will create a new and innovative urban district.
At the beginning of the Kruisweg, the housing project ‘Gemaalhuis’ marks the entrance to Hoofddorp. In collaboration with Timpaan, RROG Urban Planning and Landscape and IBB, moes have been realized in a place where offices used to dominate in the past.
The design for 83 dwellings near the center of Hoofddorp provides a transition between the village ribbon development along the Kruisweg and the large, urban scale that Hoofddorp aspires to. At the design site, the original polder structure was situated perpendicular to the direction of the rest of the Haarlemmermeer. In the design, a passage has been made here in the building block: a quiet residential court without cars and shared use of public space. The buildings are all-sided, refers to the past and seems to have been there for some time without being historicizing. The architecture is robust and stony. Rich brick details refer to the steam pumping stations that stood at the beginning of the creation of Hoofddorp. The complex is a neighbourhood in itself and has variety of housing typologies; single-family houses, veranda houses, terrace houses and apartments. The apartments are designed as freely divisible lofts.
The homes were completed in June 2020.
