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.

In cooperation with Smits bouwbedrijf, VVKH has won the european tender to develop a new housingarea in district Dieperhout in Leiden. The project consists of 48 dwellings, 12 apartments and a care facility of 1500m². Start of the constructionwork is planned in may 2015, because thats when a current school will move to a new building and the site will be available.
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 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.
The ‘Oud Woelwijk’ farm, the oldest part of which dates from before 1528, was still standing at the beginning of the 20th century in a sea of lands and bushes to the south of the village center of Voorschoten. The farm formed an ensemble with the country estate of Roucoop. The country estate no longer exists, and from 1930 the built-up area has been advanced. Yet the Essenlaan is still a protected leafy lane that leads to the old farm. For a plot directly on the other side of the farm, we have made a design for a contemporary energy-neutral home. The single-storey house with hood is designed as an outbuilding of the farm. You reach the plot via a bridge that cuts through the historic woods at a clever location. A very spacious home has been designed partly due to a number of voids. The volume is still closed on the farm side. On the south side, the house opens to the large garden.
