Yoff Urbain


Commissioned by: Dakarkids l Graduation project for Rotterdam Academy for Architecture and Urban Design

Mentor: Alexander Vollebregt

State project: Implementation on hold

Location: Yoff, Dakar, Senegal

Year: 2012

Extra: Rewarded with a 9 out of 10 with honours


Yoff Urbain involves developing an urban design and strategic plan for the Yoff Stadium Precinct (YSP), an open area in Yoff. Yoff is one of the northern districts of Dakar, the capital of Senegal. The objective is to expand the currently popular sports program and prayer activities related to the stadium into a vibrant multipurpose area for different usergroups.

The YSP is one of the few left over open spaces in Yoff and therefore

very precair. In order to preserve as much open space as possible, a

strategy is made where spaces and elements are multifunctional and

adaptable to diverse usage and future change. This graduation project is rewarded with a 9 out of 10 with honours. 


Ayigya Works! 


Assignment: Ghana Project at the Rotterdam Academy of Architecture

and Urban Design

Project Team: in collaboration with Ab Oosterwaal (NL), Sri Hidaya

(IND), Mwinlanaah Yuonayel (GH), Edwin Tukker (NL)

Tutors: Ralf Pasel (RAvB), Franziska Sack(RAvB), Ellen Geurts (IHS), Alonso Ayala (IHS)

Location: Ayigya, Kumasi, Ghana

Year: 2009


“Ayigya works!” is about supporting and encouraging trade, in which the market plays a central role. The vision of the project is to improve the living conditions of the people of Ayigya by establishing a vibrant, sustainable and flourishing working environment. “Ayigya works!” focusses on the people that live and work in Ayigya and on the existing businesses in the market area, around the bus-station and those of the street venders. If we want to work towards a vibrant, sustainable and flourishing Ayigya in which living conditions are constantly improving, realistically we have to focus on enhancing the existing qualities. The way to achieve this is with small affordable interventions, working bottom-up.


The Ghana project is an own initiative, together with Immanuel Sirron Kakpor. It accordingly became a collaboration of the Rotterdam Academy of Architecture and Urban Design, the Institute for Housing and Urban Development Studies of Erasmus University Rotterdam and the KNUST in Kumasi, Ghana. 

(K)no(w)tice Crooswijk


Assignment: Restructuring 'Crooswijk' at the Rotterdam Academy of Architecture and Urban Design

Project Team: in collaboration with Bas Pijl

Tutors: Like Bijlsma and Liesbeth Brink

Location: Rotterdam, the Netherlands

Year: 2010


The neighbourhood of Oud Crooswijk in Rotterdam currently acts more as an urban fill-up than it being a proud teamplayer in the city structure . The neighbourhoud has an internalized structure with repetetive small ‘urban islands’ and a confusing street pattern. Oud Crooswijk needs to be re-integrated into the urban fabric. The project repairs connections at three different scales: 1; the neighbourhood with the city, 2; the neighbourhood with its direct surroundings and 3; connections within the neighbourhood itsself. Design details at different parts of the urban plan adapt to the scale level they are assigned to. For example, the living environment becomes more informal as the scale becomes smaller, materials become more ‘soft’ and the envisioned programme becomes more local. Traversing all scales, water is used as an element to connect all three scale levels, as water has always played a key role in the history of Rotterdam. Moreover does the plan respond to the allocated demand for water retention of 25000m3 in 2050. 

Impression future 'feel' Bio-Science park, Almere


Commissioned by: CAH Vilentium University of Applied Science

Location:  Almere, the Netherlands

Year: 2012


CAH Vilentium University of Applied Science envisions a Bio Science Park at the school campus in Almere, The Netherlands. This Park will integrate science, education and business. The university asked Roos Ontwerp to design and visualize a imminatory park to help communicate ideas and enthuse stakeholders in this prilling stage of the project. 






Mefie incremental


Competition:  Architectural design and urban plan for middle income class dwellings, Ghana, operated by ENVIU

In collaboration with: Olga Peek

Location: Coast region Ghana

Year: 2010


 'Mefie incremental‘ means ‘my incremental house‘ in Twi, Ghana‘s first language. Mefie Incremental was a competition entry for a middle income class house design in Ghana. The design is based on the principles of incremental housing, architecturally as well as in the urban design principles. The basic units offer primary needs such as shelter to sun, wind, rain, prevents burglars and vermin to enter and offers drainage and water supply. Accordingly, the design is made such that the dwellings can be adapted and expanded according to future changes such as family size, disposable income and change in programmatic desires. The dwellings are clustered such that collective social space is orientated to one another to facilitate social interchange while the inhabitants also have their private indoor and outdoor space. The urban structure allows 50 dwellings per hectare, dense enough to realize commercial activities and services such as a doctor and a pharmacy. Open enough for everyone to have fresh air, privacy and collective public space. 

Strategy Kingfisher


Assignment:  'Rheingold' at the Rotterdam Academy for Architecture and Urban Design

Tutors: Helmut Thoele and Matthias Rottman

Location: River Rhine

Year: 2008

Extra: Nominated for the IKTINOS price


Strategy Kinfisher offers high quality nature in close proximity to cities along the river Rhine by healing its weakest spots.

Spotting the Kingfisher right in the city of Rotterdam in the delta of the river Rhine was the reason to use this exotic looking bird as a 'clean-river-approval‘. The Kingfisher has high demands in terms of clearness of water, in terms of biodiversity and he needs a relitively quiet habitat. If Rotterdam can accomodate this bird in its harbors, why don‘t aim for an entire river Rhine to be a habitat for the Kingfisher, all year through, every year? And thereby creating a healthy and attractive environment to citizens living in cities along the river Rhine.
