Villa Kogelhof by Amsterdam-based Architect – Paul de Ruiter Architects, Balancing on little more than two slim concrete posts, Villa Kogelhof barely touches the landscape it sits in, a 25-hectare wild wonderland typical of this seaside region in the south-west of The Netherlands. ‘The house is designed to blend into the landscape,’ says architect Paul de Ruiter. ‘I wanted it to be non-intrusive, integrated in the panorama and sky.
The main idea behind the architecture of the villa is that it should be nonintrusive on the environment. Therefore a large portion of the house, with spaces like the parking garage, where places into the earth, readable by the pond above the volume. The living area in contrast is hovering rectangular above the underground volume, in a glass box in the air, minimizing the footprint on the ecological area but maximizing the view on the natural surroundings and the North Sea.
- The building itself, striking and abstract, is two stacks, one underground, the other floating above it – in an uncompromising glass box supported by a steel frame. The climate-facade exterior is eco-smart. The clear insulated glass, covered with sun reflecting fabric, can be rolled up or down depending on the weather. Meanwhile electricity is provided by PV-cells on the roof and soon, a wind turbine.
- Structural elements are integrated and invisible as much as possible. A climate-active façade (a special air cavity has been incorporated into it to help control temperature) means the ventilation and heating inside the house adjust to respond to the weather.
- The box-shaped glassy residential complex was built almost 4 meter above ground, only supported by a fragile-looking V-shaped structure and the glass-enclosed stairway. Solar panels on the roof are planned to operate the house completely self-sufficient with green energy technology.
- Furthermore, 71,000 trees were planted on the property as well as a large-scale pond. The aim is to have a villa in the forest in future. Each side of the house has an unobstructed view over the surrounding landscape.
- The access to the villa is created via a deserted street. After ten minutes driving time you reach the parking entrance of the residential complex.
- For the incredibly impressive object, Thiele Glas produced numerous glass panes. The manufacturer delivered glasses for the facade, the entrance area, the underground car park, the roof glazing and extravagant glass panes for the exclusive interior design.
- The owner has plans to make the house entirely self-suﬀicient; solar panels installed on the roof will be the ﬁrst step towards that aim. With birds already ﬂocking to the immense ‘garden’ and deer and smaller animals ﬁnding their way back to Kogelhof’s nature reserve, it would be fair to say that at least the better part of the client’s extravagant mission has already succeeded.
The “glass villa” is a fascinating architectural object, which reminds of modernist icons in the middle of an extreme landscape in the Netherlands. The project was awarded for its markedly reduced architecture, the fine detailing and the fulfilment of a sophisticated standard. Such an independent, energetically self-sufficient villa can be extremely progressive. Furthermore, the building permit included the obligation to plant 70,000 trees in order to restore the original state of the surrounding landscape. What tension: currently still a detached villa on an almost dramatically flat plain, and in the future a “villa in the forest”. – AIT Award
“Villa Kogelhof is designed to be completely energy self-sufficient and is located on a swath of land declared a conservation area by the government. The minimalist building, designed with straight lines, rests on V-shaped pillars to take away as little as possible from the protected habitant for plants and animals. The interior of the house is no less minimalist due to surrounding glass panels that enhance the home’s sense of openness and connection to nature. A great design that perfectly plays up interior and exterior, while redefining the standard for natural living.” – German Design Award
Paul de Ruiter Architects:
Villa Kogelhof is designed based on complete autarky: therefore the house is energy neutral. By using several techniques, the villa will have a comfortable climate all seasons, whilst being extremely energy efficient. It was an important wish from our client to create a simple, abstract, yet spectacular villa. The result is a composition; consisting of two square stacked volumes: one underground and one floating above ground. It is designed as an uncompromising glass box, supported by a steel V-frame.
To approach the villa there is a deserted road across the estate. The estate is part of a larger program initiated by the government, which aims to connect regional ecological zones throughout the country. The current owner bought the site, once farmland, seven years ago. It is a protected habitat for animals and plants and a major tourist draw in the area, open to the public. Permission to build a house on the land was given only on condition that it was returned to its pre-agricultural state. The planting of some 71,000 six-year-old trees hint at the future of the estate as ‘a villa in the woods’ and were planted already in 2006. A rectangular pond was digged, requiring the removal of 70,000 cubic metres of soil.
After ten minutes’ drive across the estate, you reach an underground volume via a sloping driveway. The underground volume of the house consists the entrance, parking, storage and a workspace which looks out over the pond. The living area is situated in the floating glass box above ground. It’s plan is open and consists of volumes for the living room, the kitchen, bedrooms, bathroom and a patio. The façade is completely made out of glass and offers a spectacular view over the surrounding landscape. The natural setting contrasts with the technical and modern appearance of the villa, that refers to the Dutch world famous coastal defence dams known as the Delta works.
One of the main principles of Villa Kogelhof was to translate luxury into the happiness of independence. The goal for the villa was to be self-sufficient; to generate its own energy, to heat its own water and to recycle the garbage. To make sure Villa Kogelhof is energy neutral, the façade offers an important contribution. This so called climate-façade is composed of an outer layer of clear insulated glass from floor to ceiling and an inner layer of sun-reflecting fabric that can be rolled up and unrolled. When the fabric is lowered, an air cavity is formed in which the air from the villa is extracted of a central ventilation system. The house is heated by a central heating system combined with an air pump. Warm water will be generated using a biomass pellet stove, in which wood will be fired from the wood out of the private forest of the estate. Electricity will be generated from the PV-cells on the roof and in the near future also from the planned windmill.
