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.

The Kanaalpark is an office area along the Vliet on the south side of Leiden. Here, two apartment buildings are being built for starters.
Many offices in this area have long been vacant and the area looks messy and dated. The municipality of Leiden has challenged developers to take the initiative to transform the site into a high-quality living-work area. That glove is being picked up. Some offices are being converted into apartments, others are being demolished and replaced by residential buildings. Viable office owners are making a quality improvement. The municipality has drawn up an ambitious plan for the redesign of the public space.
Commissioned by the Leidse Vastgoed Maatschappij we have designed two apartment buildings for starters on the labor market. Block 1 with 88 apartments is being built on the site of an old office building. Block 2 with 41 apartments will be built on an existing parking lot. The buildings have been carefully integrated into the urban design and complete the structure of closed building blocks. Height accents are determined in conjunction with the environment. The blocks are architecturally parceled, in line with the already completed housing construction.
Urban development and architectural integration “Vomar” location, corner of Abraham van Rooijenstraat and Maarten Kruijtstraat in Noordwijk
From an urban planning point of view, the contours and height of the building plan were determined by the municipality of Noordwijk. The plan clearly defines the streets Abraham van Rooijenstraat and Maarten Kruijtstraat, in line with the existing street profiles. Gasthuissteeg will also have a clear boundary with this building plan.
The main mass has an intermediate scale between two worlds present in the environment. On the one hand, there is the smaller-scale village development of the Hoofdstraat and on the other hand, the large-scale hotel development. The mass of the new building block to be built is 3 storeys high plus a roof storey. It is articulated into a number of volumes, softening the scale of the building block. These volumes are made independent by different colors of masonry and roof finishes. With a play of rhythm between balconies, windows, tires, roof moldings and a green-copper-colored roof, the building blends in well with the seaside resort architecture of the environment. The mass on the Gasthuissteeg is 2 storeys high. It has a green facade with window openings. On the north side of the plan, the existing firebreak will be closed and the buildings will close directly on the adjacent plot.
The plan is mainly sustainable because of the triple land use. The building block has an underground floor, on top of that a storey layer, above that a parking deck for the houses and 42 houses.
Abraham van Rooijenstraat is an important access road. That is why functions such as the entrance to the underground parking garage, the entrance to the parking deck on the 1st floor in front of the houses, and the entrance to the expedition have been made here. The Kruisstraat will become more traffic-calmed. This will be the world of shopping as it is at the Hoofdstraat. This is where the shopping functions will be located, which are accessed via two clear entrances at the corners. These entrances are clearly visible from the Hoofdstraat and from the Grent.
The entrance to the houses is on the north side. This will give the existing loading and unloading yard, where other residential accesses are located, a quality impulse. The gallery facade, which is hardly visible from the public space, is conceived as a veranda world. It's a light world of painted wood.
"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.
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.
