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.

On a piece of wasteland in Leiden between the Lucebert Street and Toussaintkade an apartment building, ‘the Verleyding’ will rise this year. Construction started in March. In the building are 112 rental apartments for young professionals between 18 and 35 years. The properties are suitable for 1- or 2-person households, and have a surface of approximately 30 m2 (one-room apartment) and 45 m2 (two-room apartment).
The project is being developed and built by ten Brinke respectively Real Estate and ten Brinke Bouw. After realization the building owner will be SHWJ, Leiden. The housing design is tailored to the needs of SHWJ.
The building is 12 floors high and will become a landmark in Leiden. The area is bounded by the railway, a pond and a small park. On the park side the building stands on columns. Under the underpass, the entrance and lift are located. Together with the corridor access therefore an efficient plan has been realized, with 10 dwellings per floor. The upper apartments have stunning views over the city. The view can fully be enjoyed through the large windows. The ground level apartments have their own garden. Residents can cross a bridge over water to the park. Parking takes place on private property. The main body is constructed in a rhythm of frameworks of orange brick. The large frameworks ensure that the building looks less massive and joins well in the neighbourhood. The roof shape refers to the adjacent housing, it is finished with aluminium losagnes.
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.
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 “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.
