Restoration and extension house

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 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.

"PURE LIVING"; the winning housing concept for the ‘Klop’ location in Alphen aan den Rijn

Together with Bemog Projectontwikkeling we have developed a vision for 3rd stage of this location in Alphen aan den Rijn. The location is the final piece of the residential area of ​​Kerk en Zanen. It is located on the edge of the Green Heart, with beautiful sight lines on the polders. From the N11, the peripheral buildings will become the first sight of Alphen aan den Rijn.

A sustainable plan has been developed for this location (zero on the meter), which in terms of architecture fits seamlessly into the green environment. The 'Pure Living' concept consists of 40 terrace apartments, 20 water houses, 16 linked villas, a utility and neighborhood facility and a built-in parking facility. The peripheral buildings with the linked water houses and the two apartment buildings form the green boundary of the polder landscape of ‘het Groene Hart’. The greenery of the polder is visually extended into the buildings by giving each apartment its own (terrace) garden. The semi-detached villas are positioned in various ways and are adapted according to buyer's wishes.

In the heart of the Vijfhoek, a picturesque neighborhood in the historic center of Haarlem, stands a large building erected in 1908 by the Waaning company as a factory for Haarlemmer Olie. The building has since been designated a municipal monument. The section facing the Doelstraat originally served a representative function: richly ornamented office spaces were used to receive visitors and convince them of the remarkable qualities of this “miracle oil.” The rear section contained storage and staff quarters, adjoining an inner courtyard with the boiling room, where the sulphur-rich oil was produced a few days each year.

Since the 1980s, the building has been used as a residence. The division between the front and rear sections has been removed, yet the historic atmosphere remains tangible. The new owner asked us to develop a plan to prepare the entire building for a new century—energy-efficient, comfortable, and focused on the enjoyment of living, both along the street and around the inner garden. The boarded-up garage doors have been replaced with generous glazed folding doors. Using flax insulation, the building is insulated from within; new glazing is installed, and the roof is insulated from the outside. Heat pumps and solar panels provide sustainable energy generation. In close consultation with the Heritage Department, all characteristic elements are preserved—allowing the new residents to begin the next chapter in the rich history of this building.

In close collaboration with restoration contractor Burgy, EPOS Advies, and energy consultancy Kroon, a plan of approach was developed. Construction began in February 2024.

The “Villa van Bergenlaan” is located in Rijksdorp, Wassenaar, on the edge of a Natura 2000 protected area.
Situated along a dune ridge, it overlooks the Lentevreugd nature reserve. The villa is modest in expression, partially embedded into the dune, allowing it to become an integral part of the landscape. Energy for the house is generated from sun and air. Because the villa is partly underground, a hybrid structure of concrete and timber has been created.

The materials — including native oak, Fraké wood, concrete, and anodized aluminiumreveal their natural character; nothing is concealed, and in some cases the materials are given a special treatment, such as the wooden slat pattern cast into the concrete. The external façade, one to two storeys high, is clad in timber with concealed window frames.

Characteristic of the villa is the experience of light, space, materiality, and connection with the surrounding landscape. The villa is composed as a sequence of distinct spatial volumes — a modern interpretation of the “Raumplan” principle.
