The project for the transformation of the former VROM ministry building in The Hague, designed by Jan Hoogstad, is driven by the idea to challenge how workspaces are conventionally perceived by proposing a series of radically divergent grand interiors for the public and civil servants within the rigorous framework set by the existing building. A section of the building is opened up to the public creating a public place of work. Each of these interiors reflects the character of their programme through its morphology and use of materials. The result is a succession of interiors

ranging from dense labyrinthian library workspaces, to grand public halls, informal meeting landscapes, intimate rooms and distinct courtyards. These characteristic interiors have been achieved by carefully combining new and existing building elements and provide a range of possibilities for the renewed enjoyment of the existing building and the icon of our century; the office building. M. Pimlott (Associate Professor): ‘‘Each (interior) was highly original, from the almost Piranesian City Lobby which incorporated many diverse functions linked to the surrounding urban fabric, to the vast landscape

of shared meeting spaces containing occasional monumental figures, and the distinct atrium courtyards of the realm of offices. Each of these lent a specific and identifiable atmosphere to the places of work, and furthermore elaborated to a high degree of refinement, toward the object of a humane and beautiful environment.’’

THE MACHINE - ACADEMIC WORK Feb - Jun 2014, ‘‘A Bridge to Asia’’ Public Building Msc 2 Studio: M+ Museum (TU Delft) With Nicki van Loon and Jan Beelen Tutors: Prof Michiel Riedijk, Stefano Milani, Sien van Dam and Niklaas Deboutte.

When visiting a museum one usually isn’t aware of all the steps an artwork undergoes before it finds its place in the gallery. In the proposal for the M+ Museum in Hong Kong, we tried to include these steps that take place in the ‘‘back of house’’ into the public path of the museum to give the visitors a look behind the scenes. An artwork follows a linear path until its reaches its final destination. When it arrives in the loading dock it has to pass by the transit-depot, where it is brought in, quarantine room, where it is stored, workshop, where custom made boxed are being

packed and unpacked and labelled and restoration space, where the works of art and frames are restore from damages, before it ends up in the storage. Only a very small percentage will eventually end up on display. In our design we stacked these five storage steps vertically, each alternated by an exhibition space - which is visible in the model shown above, grey is storage and white is exhibition. By stacking the elements to a tower it becomes a part of the Hong Kong skyline and the storage tower will serve as the sign of the museum. The public can discover the

process of art conservation while it ascends the tower through series of stairs, escalators and elevators. Two concrete cores service and support the tower: one is used for circulation of the art and employees, the other for the visitors. In its ascent the visitor will find the storage spaces alternated by vast exhibition spaces - free of structure because of the trusses that carry the storage spaces above.

HET KIEL - ACADEMIC WORK Sep 2013 - Jan 2014 Complex Projects Msc 1 ‘‘Landmark’’ Studio: Revisiting a social housing masterplan by Renaat Braem Research with Boris Popma, Povilas Daugis and Yucheng Tutors: Prof Kees Kaan and Aldo Trim

After having thoroughly researched the existing masterplan by Braem, Maeremans and Maes (left) in neighbourhood Het Kiel in Antwerp, the objective was to make our own design based on the findings of this research. A number of issues - mostly related to the public realm - which had come to light while researching the project will be incorporated in the revisited masterplan. With our masterplan we tried to tie in to the existing urban structures, rather than opposing them. We proposed four building blocks on the south-side of the site that would follow the existing street patterns.

On the smaller northern part of the site we propose one large super-block that shields the rest of the development of the large road on it’s north-side. By making these blocks, with various sizes and pockets, we hoped to further differentiate public space in a number of approachable public or collective areas, that can be used and identified with by it’s respected users. One of these blocks was developed further with the continuation of the idea of collective space. The building consists of a rigid concrete structural facade that allows for a freedom of the arrangement

of the apartments within. Every floor counts four apartments, one in each corner, varying in size. Through these variations a collective space in the middle of the building is created which is connected vertically by a series of stairs. So a reinterpretation of the existing masterplan and building was created around the theme of publicness and collectivity.

PIED-Ă€-TERRE - PROFESSIONAL WORK Nov 2012 Project Architect and co-founder at Unknown architects - Apartment renovation with Keimpke Zigterman Images by Raoul Kramer

Renovation for a 17th century house in the historic city centre of Leiden into a pied Ă terre and a small office. All the non-authentic parts of this monument, like partition walls and suspended ceilings, were removed to bring back the authentic character and spatial clarity of the house. In this relatively small house three fixed multifunctional furniture elements were added. We worked with different carpenters who specialised in working with different types of wood in order to create a varied experience when ascending through the house. On the ground floor, which functions as an office

and second bedroom, a bamboo furniture element incorporates storage space and a platform, covering a guest bed which can be pulled out. On the first floor the client’s wish to make the kitchen “the heart of the house� was translated in two kitchen elements, made out of bleached nut-wood. The central element includes a table, kitchen dresser and a fixed bench that shields the stairwell and provides the best lines of sight to the outside. After completion the project has come in to interest of a number of international blogs and websites, including

DECOR - PROFESSIONAL WORK Jan 2013 Project Architect and co-founder at Unknown architects - Decor at Muziekgebouw aan ‘t IJ with Keimpke Zigterman Images by Raoul Kramer

The client asked for a décor for a performance in the main music hall of Muziekgebouw aan ‘t IJ. This large venue posed a challenge for the décor as it is contrasting with the intimate venues the ensemble is used to perform in. As a response to this we proposed a décor that stretches out over the entire width of the podium and is placed in between the artist and the spectator. The décor had to be constructed as economical as possible, so it is made of the material that was already at hand: the program booklets, hanging on seemingly invisible wires between wooden posts. The

wall of program booklets may seem like a barrier at first but upon entering the venue the audience has to come up to the podium and take their piece of the décor – the program – before returning to their seat. In this process the audience helps to take a way the barrier between themselves and the performer and shapes the décor itself. In this action they can engage in conversation with each other and the artists which brings the intimate feeling that the client wished for. On the left side the audience is entering the stage and revealing the first small parts of the musicians, they can peak through the holes and see whats

happening behind, while on the right side the end result of the actions of the deconstruction of the décor are visible while the audience is leaving the hall.

THE FRAGRANCE STORE- PROFESSIONAL WORK Jun 2015 Project Architect and co-founder at Unknown architects - Interior of ‘‘The Fragrance Store’’ with Keimpke Zigterman Images by Raoul Kramer The design of this store has been reduced to two main elements: A seven meter long cabinet for the storage and display of various fragrances and a fifteen meter long curtain that provides a warm atmosphere and separates the shop from the storage space and kitchenette. The central position of the cabinet makes it possible for the visitors and personnel to

gather around while facing each other and engage in conversation. Hundred-and-fifty types of perfume are displayed in a vulnerable, yet elegant, fashion as ‘’laying’’ pieces in a cabinet of curiosities. The display has been made entirely out of resin, while the basis of the cabinet is made out of Mahoney wood. The cheese cloth curtain is at some times flat and at other times dense bringing a different rhythm to the interior of the store. The use of materials has been carefully considered to fit the tactility and sensitivity of the products: perfumes.





GARDEN STUDIO - PROFESSIONAL WORK Jul 2015 Project Architect and co-founder at Unknown architects - Interior of ‘‘The Fragrance Store’’ with Keimpke Zigterman The studio is embedded within the garden of a traditional city-block in Amsterdam. It’s placement has been carefully considered in order not to affect the existing trees. The garden studio serves as a place where the client, a musician, can practise and teach, cello, and withdraw herself from the city. The plan is simple; a trapezoidal shape, made possible by a simple rotation of a square. A cabinet fills the corner of the space – bringing back the square into the plan

– and provides a small kitchen. The shape of the roof and the non-perpendicular walls accomplish good acoustical qualities and give the structure a further degree of complexity, both in the interior and the exterior. By slightly rotating the plan the volume sets itself apart from the border of the garden, suggesting a freestanding object. The sloped roofs emphasise the depth of the garden, while the glazing reflects the plants and trees around. The materials of the interior and exterior are each others opposites: whitewashed birch plywood panels and blackened larch battens.

Re: Letter of Recommendation | Daan Vulkers

Rotterdam, December, 2013

To whom it may concern, I would like to take the opportunity to offer a letter of recommendation for Daan Vulkers who worked in our office from April 1 until November 30, 2013. Daan began working with me upon his arrival to the office, and over the course of his internship, continually impressed me, consistently performing at a higher level than expected of him. He quickly became an integral part of the team, so much so that we asked him to stay on past his agreed end date of employment in order to finish the project he was working on. Through the course of his time at OMA, Daan contributed to a wide range of complex projects: from a structure plan for undeveloped islands in Bahrain, to a mixed-use innovative Masterplan on the Greenwich Peninsula in London, to a building proposal for the high-profile and prestigious competition for the Nobel Center in Stockholm. Even though the projects varied drastically in scale, Daan was consistently able to comprehend, analyze, and represent the proposals creatively and accurately. Daan is a very quick learner, and has a highly developed and acute graphic sensibility. He has good design capabilities and the work he produces is accurate, consistent and creative. His practical and software skills are high, and he was responsible for important production and final drawings, graphics and diagrams, as well as presentation models. One of the essential components of our work is the insistence on research, even to the point where we have established a think-tank (AMO) working in parallel to our architectural proposals. Embracing this methodology, Daan inquisitively carried out extensive research through the course of these projects, and was often responsible for research which informed the design and building proposals themselves. Throughout the course of his time at OMA, Daan displayed a positive attitude, readily accepted responsibility and completed tasks independently. Daan also fit in very well with the various teams he worked with. He is ambitious and creative, yet humble and extremely collaborative in his approach. He put in long hours under significant pressure to make sure that the deadlines were met and that the projects were as well represented as well as possible. It has been a pleasure working with Daan, and it is also a pleasure to offer my high recommendation for him without reservation. We wish him all the best in his studies and every success in his chosen career path. Yours sincerely,

Laura Baird OMA AMO Associate

To whom it may concern:

february 18, 2013

It is my pleasure to highly recommend one of my best students Daan.F. Vulkers, who has recently graduated from the Technical University Delft with a B.Sc in Architectural Design, with participation in honours programme. I’ve had the chance to teach Daan in the first semester of 2012/2013, when he joined my bachelor thesis group with inspiring enthusiasm. The bachelor thesis is the final paper in a series of dissertations that is part of an epistemology course, which is given throughout the architecture bachelor years. The core objective of this course is to reflect upon the previous and final designs created during the academic years as well as the process that led to these designs. Daan’s main design consisted of a theatre located in the harbour area in Rotterdam, which was designated to be transformed into a residential neighbourhood. The subjects of reflection in his thesis were the usage of landscape methods in the design of buildings and the usage of a public space – in the form of a square – as a catalyst of public activity. During the writing of his thesis, Daan’s natural analytical and comprehensive strengths have become evident, as this course is a good measure of a student’s ability to reflect upon his own design. The final bachelor dissertation presents a grounded theory of critical reflection on two aspects of the final design and two aspects of the design process. The main focus is on one of the aspects of the design; the usage of landscape methods in the design of buildings, for the continuation of public space in these buildings. After having first reviewed an extensive amount of literature in the relevant fields, he set out to address the aspects of his design that were not in line with the theories proposed in the literature. By thoughtfully studying these theories and cross-reviewing them against his own design, an interesting new insight was given to the subjects. The result of this comprehensive research is a thesis that has advanced his previously made design, by critically reflecting on its core issue. The thesis has therefore given new opportunities to improve the design itself as well as any other designs in the future. In sum, I would unreservedly express my support for Daan. I am confident that he will make the best of his highly creative enthusiasm and analytical thinking to further distinguish himself as not only a top student in future classes, but also a highly reliable person to work with. Please do not hesitate to contact me if you need any further information about Daan, I would be more than happy to speak on his behalf. Sincerely,

Dirk Zuiderveld ir. Dirk Zuiderveld, architect guest tutor BSc6 for Building Typology chair Building Typology Faculty of Architecture Delft University of Technology
