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.

Together with restoration contractor Burgy from Leiden, the back house, the garden house of the house at Garenmarkt 9 / 9a, has been completely restored and modernized. The new owner lives in this part. The front house with a number of apartments / studios for rent will remain unchanged for the time being.
The house at Garenmarkt 9, 9a is also popularly known as 'Thorbeckehuis'. The house has one of the largest private backyards in Leiden. In the Secret Annex, the garden house (No. 9a), the liberal statesman Johan Rudolph Thorbecke wrote in 1848 the revision of the Constitution, which turned our country into a constitutional monarchy. Thorbecke has lead three cabinets from 1849. A gable stone in the national monument reminds of the habitation by the liberal statesman and professor of law (1798-1872).
At the beginning of the Kruisweg, the housing project ‘Gemaalhuis’ marks the entrance to Hoofddorp. In collaboration with Timpaan, RROG Urban Planning and Landscape and IBB, moes have been realized in a place where offices used to dominate in the past.
The design for 83 dwellings near the center of Hoofddorp provides a transition between the village ribbon development along the Kruisweg and the large, urban scale that Hoofddorp aspires to. At the design site, the original polder structure was situated perpendicular to the direction of the rest of the Haarlemmermeer. In the design, a passage has been made here in the building block: a quiet residential court without cars and shared use of public space. The buildings are all-sided, refers to the past and seems to have been there for some time without being historicizing. The architecture is robust and stony. Rich brick details refer to the steam pumping stations that stood at the beginning of the creation of Hoofddorp. The complex is a neighbourhood in itself and has variety of housing typologies; single-family houses, veranda houses, terrace houses and apartments. The apartments are designed as freely divisible lofts.
The homes were completed in June 2020.
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.
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.
