The plot Oeverpolder is located in the central part of the Hoornespolder, a 1960s reconstruction area. In recent years, this district has undergone a transformation, where living is more focused on the public space and a clearer separation is made between public and private.
In the design for the new-build location, a U-shaped courtyard building was chosen, which in terms of architecture and grain size connects to the existing buildings. The green structure of the neighborhood is reinforced with the design. The transition between the residential building and the public space has been carefully designed. There are no garages, storage rooms and blind facades in the public space. The U-shaped building contains a total of 52 apartments of 53-88 m2. The building on Hoorneslaan has 4 storeys, the other two sides are 3 storeys high. The houses are all accessible via (widened) galleries in the courtyard, parking is partly in the courtyard and partly on public land, on the street.
The masonry architecture is in line with previous transformations on Hoorneslaan, but also fits in well with the existing modern reconstruction architecture of, for example, the adjacent Pniëlkerk. Due to the sloping boundary of the plot on Hoorneslaan, the building block has been given characteristic staggered façades here. It is an all-round designed building that at the same time has a new and unique character, but also fits well in the neighborhood.

Middelsee is the expansion plan on the southwest side of Leeuwarden, based on an urban design by West 8. The Frisian water city serves as a source of inspiration. Commissioned by the smallest housing association in the Netherlands, we have designed a plan for homes arranged around two green courtyards. It forms a small-scale community with plenty of space for encounters, and a robust waterfront with the apartment building as its eye-catcher.
Using simple means, variety is created so that no more than two houses are ever the same. The foundation remains consistent: a compact floor plan, lightly jointed red brickwork, and solid white window frames. We introduce variation through a dormer or a brick roof extension, a roof edge detail, or a distinctive entrance feature. The client’s existing housing stock in Leeuwarden’s city center also served as inspiration — a characteristic working-class neighborhood with abundant greenery.
In our plan, residents meet each other around private stoops and gardens bordered by low hedges, as well as along the wide galleries on the timber façade of the apartment building. Shared bicycle storage areas and shared cars also contribute to the sense of community.
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.
For the residential house Rapenburg 49 in Leiden, a listed national monument, we designed a plan that both enhances sustainability and strengthens the building’s historical and spatial qualities.
The house consists of a front and rear section. The period rooms in the front house have been restored to their former glory — original details and colors were reinstated, and new wall coverings were applied. The family, with two children, lives in the rear house, which they wished to renovate as sustainably as possible.
By implementing a breathable insulation system, a new insulated ground floor, and an air-source heat pump, the rear house has been successfully taken off the gas grid. During the renovation, the layout was improved, and a dormer and several roof windows were added. The connections on the ground floor between the kitchen and living/dining room, and on the upper floor between the bedroom and library, were reinstated. In all interventions, a careful balance between modern technology and historical awareness was sought.
The project was realized in close collaboration with the client, restoration company Burgy, and Erfgoed Leiden.

On the Boerhaave Campus, part of the Bio Science park in Leiden, the historical anatomy-building has been transformed into housing for Phd-students and researchers of the Leiden University. The new apartments are characterized by their high ceilings and old constructions. A small mezzanine is created to function as a bedroom. Right beside the existing building a new appartmentbuilding is erected, designed by Van Gameren of Mecanoo Architects. The total complex contains 166 apartments and is the first step in the complete transformation of the Boerhaave Campus.
