III. Nieuwe Rotte. 2017

A MSc graduate in landscape architecture with strong passion in the integration between design and natural processes.

Over the course of my studies, I have developed an interest in water and forces of nature as I believe that the underlying system of nature should be the formal component of landscape architecture. Understanding and building with these natural processes can allow the a long-lasting design which adapts to the uncertainty of the future. I do believe that landscape architecture is to create (and reveal) stories as people move through and occupy the space, their interaction with one another and with the natural beauty will transform it into a place.

MSc graduation thesis project:

Towards Resilient Delta Designing integration of natural dynamics of Dutch river delta landscape as water safety and climate adaptation measures within the urbanised delta city of Dordrecht Details Project date: September 2017 - July 2018 Project location: Dordrecht, the Netherlands Mentors: ir. Denise Piccinini, dr. Fransje Hooimeijer Type: Individual project - TU Delft Software: ArcGIS, Photoshop, Illustrator, Sketchup, AutoCAD A landscape architecture graduation research-by-design project which looks into the urbanised river delta of the Netherlands facing the problematique of collision course of urbanisation process, water safety, and climate adaptation. This thesis seeks to design adaptive green and blue network for the city of Dordrecht in order to increase the city’s resiliency towards climate change and to challenge the mono-functional and nonadaptive measures of water safety in Dutch river delta landscape as well as evoking new landscape qualities in the urban fabric of Dordrecht. This design project challenges the idea of building with nature and nature based solutions to seek balance between urban and nature through the design of a new landscape composition which presents the new perspective of living on the river and with the river.

Dordrecht represents the ongoing relationship of man and nature as a palimpsest of past processes and exchanges between the two. Here, the amalgamation of urbanisation and natural processes results in spatial separation of what is inside and outside the embanked landscape. Water safety infrastructure separates the two processes. To understand the landscape, lenses of landscape as palimpsest and landscape as process is used as main point of view of the research. Looking into practices of climate adaptation measures and case studies as well as landscape structures of the site, design framework is produced as the cornerstone of the design outcome.

The design solution seeks a balance of re-connecting the river dynamics of the rivers through the city of Dordrecht, which not only re-establish the river as part of the city, but also to develop new ecological values. The concept of “living with the river� guides the urban processes on the newly established riverscape, and provides open-endedness of the landscape with the dynamic of the river continuously shaping and reshaping the landscape overtime. This landscape redefines not only the urban processes, but the economic value, ecology and water safety as part of the adaptive system.

The Site

The river delta of the Netherlands is a series of regulated natural waterways as main water transport towards inland Europe. Dordrecht sits on a busy intersections with its urban and agriculture landscapes are encircled by protective dikes.

Design strategies

Strategic opening of dikes will allow river water to come inside the embankments and transform the polders into dynamic zones which develops new emerging ecologies and combined with resilient housing, dynamic agriculture, and recreation.

Hypothesis - Design vision: a new dynamic landscape Problematique

The inner island of Dordrecht sits lower than the riverine landscapes outside of the dikes and the water level is artificially regulated through a series of canals and ditches. This results in the incapability of the inside system to cope with

sudden changes in water level, not only due to the river water, but also due to cloudburst flooding. In an extreme case of dike failure, the urban and agricultural landscapes inside the protection of these dikes will not be able to ‘absorb’ these natural forces.

The forces and dynamics of nature, that for centuries has been kept outside, the dikes can be ‘invited’ inside in order to generate unique landscape qualities of the delta, and make the urbanised landscapes more resilient and adaptable to uncertain change, not solely dependent on the integrity of dike structures. Inviting the flow of the river to ‘flow through’ instead of ‘flow around’ can be explored as a way to intertwine the two dynamics. In the end, a balance of both urban and nature can be achieved by interweaving one another, without sacrificing one or the other.

Landscape transformation

The design transforms the existing polder landscape into a dynamic zone by preparing the necessary groundworks to expose the low-lying landscape into the river dynamics. Here, the river is allowed to flow through the landscape and thus exposing it to the temporary fluctuation of the river water and the morphodynamics processes of the river. New gradients are developed naturally which can generate new riparian ecologies. Existing dikes is utilised as main access roads supported by new road access/dikes through the dynamic zone by emphasizing natural relief currently present on the landscape.

Emerging ecologies - new gradient

Within the new green-blue network, 4 different new ecologies can be predicted to be naturally developed based on the similar conditions on the existing neighbouring nature parks based on Natura 2000 classifications. At the edge of water body, submerged plants will grow on the shallow water.

Moving further inland and slightly higher gradient will develop riparian marshes that dominated by reeds and perennials will grow and can tolerate daily inundation from the river.

Holwerd as Eco-Topos Dutch Waterscapes - Design of Leisure Landscape Details Project date: November 2016 - February 2017 Project location: Holwerd, Friesland, the Netherlands Mentors: ir. Denise Piccinini, dr. ir. Inge Bobbink Type: Group project (2 people) - TU Delft (materials displayed are own drawings) Software: AutoCAD, Photoshop, Illustrator The village of Holwerd is located on the northern part of the Netherlands in the province of Friesland. Located south of the coast of Wadden Sea, Holwerd used to be affected by the dynamics of the tide and its livelihood used to depend on the resources from the sea. The village is protected by a sea dike that was constructed in the 16th century, thus transforming Holwerd into agricultural village. The dike distinguishes the separation of from the village, to the polder landscape, and out to the salt marsh landscape. The village is compact and rather organic, contrasts with the strictly defined boundaries and openness of the polder landscape.

The vastness and uniformity of the polder area dwarfs the village of Holwerd and isolates it from the traffic of people moving to the pier towards Ameland. Nevertheless, the village is significant in orienting oneself within the landscape. Especially one can always rely on the towering church of Holwerd as a reference point. Furthermore, the visual presence of the dike is just as compelling as the church tower.

The design transforms the polder landscapes in between sea dike and Holwerd as new recreational landscapes that adapts the conditions of water level, soil condition, and topography into valuable landscape characters. Other than connecting the village of Holwerd with the Boezem water system for better water transport, new harbour on the west of the village will become new commercial and waterfront hub that attracts new developments. This new water body will be connected to the transformed polder landscape, hence the new leisure landscape can be accessed by foot and water from the village of Holwerd.

Transformed polder landscape will create dynamic visual qualities that attract visitor to roam the landscape whilst experiencing different kinds of vegetation and landscape qualities based on the conditions that are created. Exploration on this new landscape adds an opportunity of recreation on a natural landscape that is missing in the area, therefore, invites more people into the village.

The intervention will be kept minimal as to earthworks to develop different conditions for different vegetation and different biotopes and accessibility. Overtime, the landscape will naturally be colonised based on these conditions and based on management (grazing, or not). Overall, the landscape respects the historic patches of the polders whilst introducing new qualities that works with the natural processes.

Nieuwe Rotte Designing integration of Rotte river with the urban fabric of Rotterdam Details Project date: November 2016 - February 2017 Project location: Rotterdam, the Netherlands Mentors: ir. Frits van Loon, dr. ir. Rene van der Velde Type: Individual project - TU Delft The river Rotte runs through the middle of Rotterdam connecting the city centre onto the green agricultural areas north of the city. However, the river does not begin in the city, at least that’s what people think.Years of development along the river bank had turned the city away from the river. Over the years, the river becomes more of an engineering feat than a pleasing natural element. Green structures are scattered around the river with no cohesiveness between them. The river is not always accessible, with different neighbourhoods have their own way of dealing with the river. Some privatise it, some beautify it, and some other neglect it.

The vision for the new rotte is aimed to deal with such problematique and to provide a better way of reconnecting the city back into the sad and old river. Furthermore, the growing population of the city provides opportunity to redesign the neighbourhoods along the river.

Design strategies will transform the Rotte area into a more inclusive, vibrant, and active. These principle can be applied into strategic areas along the river bank as well as surrounding potential areas.

The first strategy is to break up the old existing neighbourhood and to introduce new typology that is higher in density but more inclusive due to penetrable semi public communal green in between buildings. Commercial, office and underground parking spaces will become a driver of more active and walk-able neighbourhood.

Areas along the river bank will be redefined to be more natural with riparian planting and soft edges. This strategy will create accessible river with connected experience from the city centre towards the green area. The use of cars will be limited within the area and car parking is available underneath the newly constructed buildings. This will promote walk-able neighbourhood, active social interaction, and together with new commercial spaces, high economic value.

Finally, the third strategy is to redesign existing potential open spaces to be a new public park as a place for culture and recreation. Areas such as the Binnenrotte have the potential to be utilised and together with new inclusive neighbourhoods these areas can connect the urban fabric back into the river Rotte. Cultural values and historic significance of these spaces are also preserved and represented to create a sense of place in the New Rotte. In the binnenrotte area, the river’s presence is reintroduced in a way of linear urban wetland which creates captures the water from surrounding pavements and cleansing the water by slowly let it flow through constructed wetland planting before letting it flow out northwards to the river.

Miramar Peninsula Intensification Plan Details Project date: July 2014 - November 2014 Project location: Miramar, Wellington, New Zealand Mentors: Martin Bryant Type: Individual project - Victoria University of Wellington The project deals with the growing population of Wellington. The currently unused Department of Defence land in Miramar Peninsula is the site for the residential intensification programme. The peninsula currently consists of regenerated pine forest, gorse bush and a farm. The hilly topography and site’s vegetation create different movements across the site which the concept of the whole scheme evolved from.

The development on the Miramar Peninsula is focused on preserving natural elements of the site as well as creating a lively and inclusive neighbourhood. High density residential development is chosen to be implemented on the eastern part of the peninsula to minimise the impact of building footprints to the natural landscape as well as to reduce visual impact from the areas west of the site including Wellington City.

Spatial experiences created on the constructed landscape evolves from the idea of “moving through the hillside” and largely based on the walking experience through the site. This concept is represented in the Miramar bush walkway structure which takes place in the regenerated native bush area. Walking through the walkway experience is designed to immerse oneself into native bush as the original walking experience produces.

To accommodate the new neighbourhood, the development includes; new infrastructures, new recreation or sports and community centre and the refurbishment of the existing prison building into a public square and commercial area as well as preserving and restoring other heritage sites for recreational and educational purposes.

To explore the nature areas around the development, non-intrusive bush walkway is designed. Due to the challenging terrain, the structure will be cantilevered and elevated above ground with steel mesh pathway do totally “immerse”oneself into the naturally growing bush. Steel material is used to provide contrast between the man made and natural elements and it makes the structure possible to be constructed lightly and assembled quickly without much intervening with the natural landscape.

Jivana Homes Public Garden Design Details Involved in project: May 2015 - December 2015 Project location: Surabaya, Indonesia Role: Planting plan, shrubs and tree species choice, material choice, supervision of garden construction, design consultation.

Type: Individual involvement (representing the property company). Garden layout and design in collaboration with Jakarta design firm D-Associates.

In this project I was involved from the finalisation of design and implementation phase.

The design from the architect is a town house residential complex with a linear public park running through the middle of the site. It was planned to be a contemporary park with themes and lush tree canopy. In the beginning of my involvement in the project, I was tasked to consult with the design firm. Due to no landscape architect involved previously, the design was somewhat mismatched along the length of the park. I made plenty of design changes, in discussion with the architects representing the design firm to further support the public interaction and exploration in the park, as well as continuity between the different programmes of the linear park.

The trees were the first to be planted, together with the hired horticulturist, I designed the tree plan which combines different species to support dynamic visual qualities while providing enough canopy to be comfortable in the hot Surabaya weather.

Under the tree canopy was designed to be covered with grass, however, I proposed a planting plan combining low shrubs and structural plants, as well as, nurturing wild shrubs from surrounding areas as they have interesting characters, unique, and acclimatised to the condition. The plan was approved and I was in charge of choosing the different plants and supervising its planting process as well as the construction of hard scape in general. Problems arose such as difficulty in construction, time, material choice, unsuitable plants were mitigated together in discussion with the field team.

In the end, the park will be a unique part of the whole development providing a natural refuge close to home whilst promoting social interaction and recreation.
