P o r t f o l i o Architecture

Walter Brouwer

P o r t f o l i o I n t r o d u c t i o n This portfolio was made by Walter Brouwer after finishing the study of architecture at the university of Delft in 2012. I did my Master in Delft, after finishing my Bachelor degree at the HTS in Arnhem. In this document I will show three different projects and some related design techniques. The first project shown is my graduation project, which gets the most attention in this portfolio. At the architecture faculty in Delft there are different graduation labs to chose from. I chose SADD (Strategic Architectural Design Development), because of the theme of the available project: Making a design for the United Nations headquarters for sustainability. Nowadays sustainability is a very important theme in the world in general and also in architecture. Sustainable designs are important for improving our environment and reducing human energy consumption. The second reason I chose the SADD lab is the technical and practical nature of the project. It connects well with my background. The second project is a project I did at the university of Delft. The concept was very abstract (a metaphor). The translation of the concept to the shape of the building has some really great spatial values. The semester was focused on the design of a library. The last project is some work I did after my graduation. It is a rapid prototyping process where I gave some assistants in the visualisation processing, so it could be 3D printed/milling.

Manhattan The Island Manhattan is the centre of New York and is one of the biggest in the world. When you look at the picture of Time Square you can see it is really crowded. This is not strange because the density of Manhattan is very high, especially in the middle/southern part of the island. When walking through the streets you will be surrounded by tall buildings and skyscrapers. It looks like “a concrete jungle.” What are you going to do when you want to escape from this all? Because of the high density the city will not provide you with a lot of green. However, New York does have a big central park. Besides Central Park there is not that much public green, so there is a big contrast in Manhattan. On the one hand you have the over-crowded, high-dense business district with lots of buildings and people. On the other hand you can escape this all in the few quiet, green and natural surroundings of the parks. The United Nations is located in New York District 6, in the area called Midtown East. The area around the UNHQ is very densely built. The Central Business District of Manhattan Midtown has its inner centre close to the UNHQ plot. The gridstructure ensures New York’s car traffic flow is almost uninterrupted. Variations occur at the river side, where different solutions for traffic with respect to buildings have been made. There is very little public accessible open space in the area of the United Nations. The intensity of the green in the public accessible spaces is mostly low and there are too few green public spaces with a real park character.

Design development



Building block

Passage way







Manhattan Manhattan needs to have more spots of green spaces. One initiative undertaken to achieve this goal is the green waterfront. Right now there are a couple of developments that create a greenway around Manhattan. Instead of only having a focus on the green of the central park, you will have central park reaching out to the waterfront. This way there will be a better mixture of high density and green. Because the UNEC Building is located on the existing United Nation plot, which is on the shore of the East River, a green waterfront must be provided. Midtown East is the district where the UN is located and it is very close to the Central district. In both districts the amount of green is very low. Most of the waterfront is already greenway, but there are a couple of places left for developing. One of the biggest gaps in the green waterfront is at the UN plot: The GREEN Gap. The master plan and the new UNEC building could provide a better quality environment by creating a public park for Manhattan. In the existing situation there is a highway, called Franklin D. Rooseveld Drive, located under the plot of the UN, so there is no space for a greenway at this moment. The points of security, green and traffic flows are leading the design of the master plan, considering the future development and possibilities to integrate with a sustainable building for the UN.

Manhattan Creating two atria with different atmospheres Connecting the green to the waterfront Connecting to existing UN buildings Formal outside vs informal inside Using the available views Sustainable integrated Bringing green inside

Manhattan In the project a formal upper block with a transparent plinth and an informal inside space (atria) are created. The two atria have a different function and materialisation. The materials on the inside and outside are made from natural materials, e.g. with stone on the outside and wood on the inside. The amount of glass on the outside has been limited. Nevertheless there is still a lot of indirectional light, which makes for a good atmosphere and climate. The building has a heat recovery system and it also uses the water basin in front of the building as greywater system. The rainwater falling on top of the building will be absorbed by the green roof and directed to the water basin. The facades are made out of thin plates to reduce the construction costs. The stone and wood for the facades are both local materials, which combine well with the existing buildings and surrounding on the plot.

Amsterdam In Amsterdam the ‘Indische buurt’ is one of the 40 former ‘problem neighborhoods’ in the Netherlands. The new building should work as a positive catalyst for the area. There are only closed blocks in the surroundings. The new design will be a public place that connects the neighborhood and will function as the centre of the district. The space that is created is open and the building itself will create even more space. Sunlight is important to create a nice atmosphere. This atmosphere is also the reason why the tree/forest theme is used as a metaphor.
