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.

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.
The plan ‘de Biezenhof’ is part of the new residential area ‘Waterrijk Woerden’ and is situated along a natural watery region. The urban scheme of ‘Waterrijk Woerden’ was designed by West 8 and refers to the traditional Dutch water cities such as Delft and Leiden. The design is made in collabiation with Klunder architects. Almost every dwelling is individual and has a specific connection to the water.
The plan of Biezenhof is divided in two parts: there is one block of family houses around a courtyard on the edge of the lake, and there is a row of water houses and apartments along a canal.
The buyers of the houses could choose between several types of houses as well as between four architects. Due to the possibilities in combining type and architect, not one house is the same. Every house has a singular character: the lake houses have a beautiful view on the lake, the street houses have a garden, and the canal houses enclose big terraces. In the public space there are a few parking places, the majority of parking places are organised in garages.
The houses designed by Knappers are characteristic because of the huge roof overhanging the façade. This contributes to the shelter-against-the water identity of the houses, and refers to the greenhouse glass constructions in the low lands. At the street side these houses are made of brick, which gives them a closed and open (to the light and the water) individuality.
The new faculty OCP of Delft university of technology, accommodates the disciplines of Mechanical, Maritime and Industrial Design. During the constructionworks school continued. The new building shows a contemporary, logical and efficient architectural structure with it's own recognizable facade in the TU-district. The interior design is executed as an integral part of the whole plan.
New hotel formula in Hoofddorp
In 2016, we conducted a study on behalf of CTI (Control Towers International) into the possibilities of accommodating a hotel in an existing office building in Hoofddorp. The detached office building with parking garage at the Kruisweg 106 is part of the business park "de Hoek" in Hoofddorp. The building is a stone's throw from Schiphol and Amsterdam and is easily accessible by car and public transport.
We then made the design for the transformation into a hotel with 133 rooms and various facilities, such as a restaurant, bar and lounge.
Based on the study and design, the zoning plan has been adjusted in consultation with the municipality and an interested market party has been contracted: Centro Hotels from Germany. The design was then fully tailored to Centro's wishes. A completely new, trendy hotel formula for the Netherlands will be introduced in the building; the "Ninetynine-hotel Amsterdam", specifically aimed at the younger target group. Vitamin-E has provided the interior design of the Ninetynine formula on behalf of Centro. The new hotel will be a good addition to the current offer in the municipality of Haarlemmermeer.
The demolition work was carried out in 2017, and in November 2018 the transformation of the existing office building into a hotel started.
