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.

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.
Housing association St. Willibrordus wants to renew 40 duplex houses along Stompwijckstraat in Wassenaar. The program provides for the realization of 86 social rental homes, mainly for starters and seniors. The plan area is located in a village extension from the 1960s. At the time of completion, this was the northernmost district of Wassenaar and it overlooked the meadows and farms. The district is spacious with a focus on greenery. In the development of the plan, we link up with the basic qualities of the neighborhood with spacious profiles with front gardens and lots of greenery. In order to be able to make the closed building block, the Stompwijckstraat in between will be removed. This provides space to solve parking for residents within the building block. The plan also provides for a communal courtyard with a social facility adjacent to it.
To create privacy in the front gardens, we create a green strip between the front gardens and the sidewalk that remains the property of the municipality. The existing structure of mature trees will be maintained. There is a distinction between a formal front, with zoom houses on the ground floor all around that are accessible from the street side, and an informal rear with parking under an open green deck (through which existing large trees protrude) and the access to the houses on the upper floors. through wide galleries. In the long streets, the building blocks match in scale with the buildings on the overlying because the top (third) storey has a setback in relation to the building line. On three sides of the building block, the balconies of the houses on the upper floors hang from the building blocks as ornaments. The balconies provide contact with the street and respond to the orientation with respect to the sun by means of a rotation and still show the echo of the current situation. The building block responds somewhat more robustly to the northern park side. On the northwest side, one of the blocks reacts in height to the adjacent apartment building.
Villa Meijendel takes its name from the nature reserve in which it is located, where a forest meets a valley of dunes. The house is constructed from concrete and set into the side of a sandy slope. The building's design aims to create a dialogue with its surroundings, both through the way the form and materials engage with the landscape, and through the use of glass to provide views out from and into the house.
The boxy geometric structure is entirely clad in charred timber, creating a textured black surface that appears different depending on how sunlight falls on it. The exterior finish, inspired by the ancient Japanese shou sugi ban technique, also helps to preserve the wood. Sometimes the house is almost invisible against the dark edge of the forest, sometimes it sparkles in the sunlight because of the glittering charred wood, as such forming a background for the play of shadows of tree trunks and branches. The villa hides and reveals itself in the landscape.
The property has its entrance on a middle level accommodating an office and two bedrooms. Stairs ascend to an open-plan kitchen and living space, and drop down to a master bedroom and gym room.
The living room features a full-height corner window that looks out through the trees towards the dune valley. A lower window facing to the rear and a large glazed surface lining the adjacent double-height circulation area face out onto the forest. At the far end of the first floor, sliding glass doors lead out from the kitchen onto a terrace.
The material palette –concrete, steel and anodised aluminium– was chosen to complement the tones and textures of the surrounding environment. Each material is applied in a raw, untreated form. Internally, the walls are finished with smooth concrete, while the rough-sawn Douglas fir beams supporting the ceilings feature a distinctive grain.
West 8, Adriaan Geuze, is responsible for the garden design.

For the Hoge Rijndijk location in Zoeterwoude, a new construction plan has been developed for an apartment building with starter homes, after demolition of the existing office building. The building stands on the edge of the large-scale buildings that are currently being built between the Oude Rijn and the Hoge Rijndijk, and the existing residential area from the 1980s. It adjacents to a small park on the east side. The new building has been placed in the building line of the Rijndijk and thus strengthens the profile of the road. The parking spaces are located in the rear area, lined by green. By dividing the building mass in three, a smaller scale is created, which is further reinforced with differences in brickwork and roof shape. The building will contain 34 residential units of approximately 50 m2 and a bicycle storage. An extremely energy-efficient and sustainable design is achieved with individual heat pumps and solar panels on the roof.
The permit application is being processed, implementation is expected in 2021.
