Overview + Perspective

Bird's-eye view of H+N+S

In recent years, projects of H+N+S have been realized throughout the Netherlands. Photographer Siebe Swart has taken beautiful aerial photographs of many of these projects. Take a bird's eye view of the H+N+S projects on this page. Are you flying?

National Military Museum

The Soesterberg Air Base, which until recently was hermetically sealed, has been open to the public since 2015. At the heart of the base is now a museum where indoor and outdoor space merge seamlessly. During their visit, interested parties will have the opportunity to learn more about the Dutch armed forces and the surrounding new nature. View the project >

Hunting lodge St. Hubertus

At the beginning of the twentieth century, the Kröller-Müller couple realized their dream in the Veluwe. The exclusive country estate of this wealthy couple is now open to the public and the Hunting Lodge itself has recently been completely renovated. H+N+S made the redesign of the gardens and park, allowing visitors to walk along the ponds again, just as the Dutch architect Berlage intended it a hundred years ago. View the project >

Landscape plan Maasvlakte 2

The objective of the Port of Rotterdam Authority to expand the port area with the expansion of the Maasvlakte is combined with the realization of space for recreation and new nature. H+N+S made the Landscape Plan for this. View the project >

Land art park Buitenschot

Commissioned by Schiphol, a multidisciplinary project team worked on a world first. A park that exists by virtue of the low-frequency ground noise caused by aircraft taking off. Due to its design, the park landscape contributes to a significant reduction in noise nuisance. View the project >

Bird Valley Maasvlakteplaza

The Slufter complex is located where Maasvlakte 1 and 2 meet. Old clay maturation fields and settling basins are no longer necessary. The space that becomes available will be given a second life as a secure truck park plus a completely renovated bird valley. The development of the port and nature go hand and hand here.

Room for the Waal Nijmegen

This is the most complex project within the Room for the River programme. A unique assignment in which, in addition to water management measures, such as the construction of a secondary channel with inlet work, dyke relocation and nature development, three new bridges are being built. In addition, there will be an inhabited island in the middle of the river. H+N+S fulfilled the role of coordinating architect and was responsible for the landscape design. View the project >

Sand engine

A pilot has been carried out with the Sand Motor involving the application of a large amount of sand off the Dutch coast. After construction, this sand will be spread by wind, waves and sea current along the coast between Hoek van Holland and Scheveningen. As one of the authors of the 'Kust booklet' (2006), H+N+S was involved in the development of the 'sand engine' concept at an early stage. View the project >

Bypass Kampen

The construction of the Reevediep, a new estuary in the IJssel delta near Kampen is one of the largest Room for the River projects. The Reevediep is intended to be able to discharge high water from the IJssel in extreme circumstances via the Drontermeer and Vossemeer to the IJsselmeer. H+N+S has been involved in this project since 2014: until 2014 on the side of the Province of Overijssel and project partners, and from 2014 on the side of Isala Delta, the combination that is implementing the plans.

The Central Axis of Friesland

We have interpreted the task of designing De Centrale As (N356) and its landscape integration into the national landscape of the Northern Frisian Wouden as a contemporary cultural task: designing both the artworks and the road itself and also the 'receiving' landscape around it. View the project >

WWTP Hilversum

The new WWTP of Hilversum has been built next to the old WWTP – now a new residential area under construction. A closed area, but it is still part of the environment. The new site flows seamlessly into the adjacent Gooi Nature Reserve. View the project here >

Geniepark Hoofddorp

The Defense Line of Amsterdam is an oasis of tranquility in the Amsterdam metropolitan region, with special ecological and cultural-historical value. Its recreational potential is also being discovered more and more. With the Genie Park, an important link is added to this 'Silence theorem'. View the project here >

Estate Haverleij

Urban expansion northwest of Den Bosch with an innovative residential concept in a green setting. In the area of 220 hectares, 1000 homes are housed in nine castles and a castle, scattered in the landscape. Three zones have been distinguished: a rugged reed zone on the edge of the recreational lake Engelermeer, an estate forest and an estate garden. Central to the estate park is a golf course (of approximately 80 hectares) and a nature reserve (40 hectares) managed by Staatsbosbeheer.

Hoeckelingsdam, Waterland coast

To compensate for the new residential area of IJburg, a sand dam of approximately 1.5 km was constructed in the IJmeer off the Waterland coast in the early 2000s. Due to the construction of the dam, a wind and wave-calmed nature reserve has been created against the Waterland coast, sheltered from the east wind, which is ideal for birds and as a spawning ground for fish.

South Willemsvaart

The Zuid-Willemsvaart is a canal between Maastricht and 's-Hertogenbosch. It serves as a lateral channel of the Meuse and thus forms a shorter route for shipping between the Belgian and the Brabant-Gelderland part of the river. A bypass has been created with a new route, along the city of Den Bosch. A plan for integrated area development ensures that the new bypass has a good place in the area, with added value for nature and recreation.

Wagenwerkplaats Amersfoort

It is getting busier and cozier at the Wagenwerkplaats, home base of H+N+S Landscape Architects. The vacant lots of the former NS workshop are ideal for a mix of functions, including housing. H+N+S and Imoss designed the Masterplan together on behalf of the NS and the municipality of Amersfoort. In the meantime, construction has started. View the project >

Nesseland Rotterdam

Waterwijk Nesselande is a spacious new-build neighborhood located on the Zevenhuizerplas to the northeast of Rotterdam. The urban design was determined together with Palmbout urban landscapes. In addition to the outdoor space plan with a strong water structure and green ribbons, we have also designed various bridge types that reinforce the character of the area as a 'water district'.

Green-blue Slinger

The Green-Blue Slinger is a series of nature and recreation areas sandwiched between the highly urbanized areas of The Hague, Zoetermeer and Rotterdam. The mountain basin at Oude Leede is the basis of this Green-Blue Slinger, which is intended as an urban run-off area between The Hague and Rotterdam. The master plan for the green zone between Pijnacker and Berkel, which we co-created, is based on a coherent perspective with the following objectives: a recreational area for the inhabitants of the surrounding urban regions, a water system that can act as a buffer for the rapidly urbanizing surface in the north - and south side, and an ecological connection between Midden-Delfland and Midden-Holland.


For decades, the reinforcement of dikes has been regarded as a strictly civil engineering task. From the 1990s, this slowly changed and the landscape design of dikes was seen as an integrated design assignment on the border between civil engineering and landscape architecture, with attention to experience, shared use and history. The dike has a concave structure: at the top it is narrow and steep, at the bottom it slopes broadly. This met the technical requirements, but at the same time gave the profile a certain tension. A distinction has been made between the design on the inner and outer dike side of the dike. View the project >

Leidsche Rijn

The Rijnkennemerlaan in Leidsche Rijn is the result of two water supply pipes from the Water Supply Company, which have been laid in the ground in a twenty-metre-wide zone of right in rem. In the Development Vision, a 35-metre-wide zone has been kept free from buildings. The Rijnkennemerlaan is conceived as an endless empty avenue: the horizon in sight. The perspective is framed on both sides by a row of Italian poplars. View the project >


We designed the Noorderbos in collaboration with Buiting Advies on the polluted flow fields of a former sewage treatment plant on the north side of Tilburg. The diked waterways give the forest structure and tell about its history. The first trees in the Noorderbos were planted in the early 1990s. By planting trees in different sizes, densities, types and mixes, varied conditions are created that create a high ecological value from the moment of realization and already produce a varied and interesting picture after a few years.

Beatrix lock

The Princess Beatrix lock near Nieuwegein is the largest monumental inland waterway lock in the Netherlands. This canal is the most important direct connection between the ports of Rotterdam and Amsterdam. Because more and more ships use the Lek Canal, the Princess Beatrix lock threatened to become a bottleneck. For this reason, a third lock chamber has been constructed and the canal has been widened, with consequences for many historical objects of the New Dutch Waterline. It was decided to preserve these objects by picking them up as alienating Objets Trouvé and 'carelessly' placing them back in the landscape a little further on. View the project >

Zevenaar East

Urban development plan for Zevenaar East (54 ha housing and 93 ha business park). The inspiration for the plan stems from the landscape characteristics of the area. The specific location in the Rhine Strangen landscape at the transition from levee to bowl soil on the one hand and the typical occupation pattern around Zevenaar of separate hamlets in an agricultural landscape on the other hand.


In 1993 and 1995, Limburg was startled by two major floods from the Meuse, resulting in major economic damage. The Ooijen-Wanssum Area Development offers a definitive, future-proof solution to the high water problem. It is an integrated area development with, in addition to flood risk management, also objectives in the field of nature, landscape, mobility, quality of life and economic developments.

Commissioned by SBB, we are involved as consultants in various projects on the Wadden Island of Vlieland. The aim is to link recreational developments with ecological gains. H+N+S developed design principles for three projects on the island. For example, the starting points for the expansion of the Stortemelk camping site with holiday homes have been formulated and advice has been given on the placement of a permanent beach pavilion. Important conditions for the latter were keeping the foot of the dune clear so that it does not form a blockage in the sedimentation and erosion processes. View the project >


The dyke improvement between Hagestein and Opheusden falls under the national Room for the River programme. In that program, spatial quality, in addition to working on our safety at high water, is explicitly stated as a second objective. That can be seen. The southern dike along the Nederrijn and Lek has a clear and compact main shape that is integrated into the landscape. In this way, the small-scale and varied character of the Betuwe levees remained intact. View the project >


Commissioned by the Stichting Landgoed Windesheim, H+N+S has drawn up a master plan which forms the basis for a step-by-step approach. The new park bridges on the Windesheim estate will open in the summer of 2021. The design is by NEXT architects in collaboration with H+N+S. In the tradition of the romantic park design by Jacob Otten Husley, the park bridges have added an interesting layer of 'garden cieraeden' to the estate in one fell swoop. View the project >
