6 apartments in monumental building Plantsoen 1 - 3 Leiden

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.

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.

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 plot Oeverpolder is located in the central part of the Hoornespolder, a 1960s reconstruction area. In recent years, this district has undergone a transformation, where living is more focused on the public space and a clearer separation is made between public and private.

In the design for the new-build location, a U-shaped courtyard building was chosen, which in terms of architecture and grain size connects to the existing buildings. The green structure of the neighborhood is reinforced with the design. The transition between the residential building and the public space has been carefully designed. There are no garages, storage rooms and blind facades in the public space. The U-shaped building contains a total of 52 apartments of 53-88 m2. The building on Hoorneslaan has 4 storeys, the other two sides are 3 storeys high. The houses are all accessible via (widened) galleries in the courtyard, parking is partly in the courtyard and partly on public land, on the street.

The masonry architecture is in line with previous transformations on Hoorneslaan, but also fits in well with the existing modern reconstruction architecture of, for example, the adjacent Pniëlkerk. Due to the sloping boundary of the plot on Hoorneslaan, the building block has been given characteristic staggered façades here. It is an all-round designed building that at the same time has a new and unique character, but also fits well in the neighborhood.
