Essenlaan Voorschoten house, contemporary and 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.

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.

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).

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 “Meerwijk” district in Schalkwijk, built in the 1960s, has been built on the corner of Bernadottelaan and Albert Schweizerlaan. This center is part of the urban design that was made by our office in 2001. The building with retail spaces, including the Vomar supermarket, an underground parking garage with 215 places and 74 apartments, is one of the sub-plans of the community center. The whole has a modern, transparent and friendly character and adapts well to the neighborhood.
