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.

Urban development and architectural integration “Vomar” location, corner of Abraham van Rooijenstraat and Maarten Kruijtstraat in Noordwijk

From an urban planning point of view, the contours and height of the building plan were determined by the municipality of Noordwijk. The plan clearly defines the streets Abraham van Rooijenstraat and Maarten Kruijtstraat, in line with the existing street profiles. Gasthuissteeg will also have a clear boundary with this building plan.

The main mass has an intermediate scale between two worlds present in the environment. On the one hand, there is the smaller-scale village development of the Hoofdstraat and on the other hand, the large-scale hotel development. The mass of the new building block to be built is 3 storeys high plus a roof storey. It is articulated into a number of volumes, softening the scale of the building block. These volumes are made independent by different colors of masonry and roof finishes. With a play of rhythm between balconies, windows, tires, roof moldings and a green-copper-colored roof, the building blends in well with the seaside resort architecture of the environment. The mass on the Gasthuissteeg is 2 storeys high. It has a green facade with window openings. On the north side of the plan, the existing firebreak will be closed and the buildings will close directly on the adjacent plot.

The plan is mainly sustainable because of the triple land use. The building block has an underground floor, on top of that a storey layer, above that a parking deck for the houses and 42 houses.

Abraham van Rooijenstraat is an important access road. That is why functions such as the entrance to the underground parking garage, the entrance to the parking deck on the 1st floor in front of the houses, and the entrance to the expedition have been made here. The Kruisstraat will become more traffic-calmed. This will be the world of shopping as it is at the Hoofdstraat. This is where the shopping functions will be located, which are accessed via two clear entrances at the corners. These entrances are clearly visible from the Hoofdstraat and from the Grent.

The entrance to the houses is on the north side. This will give the existing loading and unloading yard, where other residential accesses are located, a quality impulse. The gallery facade, which is hardly visible from the public space, is conceived as a veranda world. It's a light world of painted wood.

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.

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.
