SoundScape
Traditionally, buildings focus on the visual experience. Though vision is probably the most important sense, emotions get triggered more easily by sound.SoundScape is a building that aims to trigger the emotions of its users by providing a sound experience. It consists of an auditorium for all kinds of concerts, but also lectures and conferences; a public sound route and a private one that contains cells for individual sound experience.
SoundScape is not an autonomous building. It is one of the seven sub buildings that form the bigger structure of 2628Climator. The position of SoundScape in the plot, with three adjacent sub buildings raises the demand of good connectivity, on both ground level public space, as well as on other levels and private space.
The building should be a hub but not a place of just movement. The building is also a place of permanence. It is works as a heavy star that deforms the space-time or gravity field. People in a hurry will move through it and get deflected a bit – the building works as a distributor, whereas people with less ‘speed’ have the chance to experience the entire sound route.
What’s in a name: SoundScape is indeed a formation of a layered landscape. The geometrical properties of the double helix were exploited to achieve this effect.
The underground auditorium is the main sound producing part of the building. On top of it, a core acts as construction, climate and sound element. From the auditorium the private soundscape emerges. The private soundscape gets ‘injected’ by sound from the auditorium through the use of the Ampli, an interactive amplification device, which is placed in wall and ceiling. The public route is occupied by alien-like sound cells. These cells also have Amplis to allow sound to go inside, outside or reflect, changing the character of each cell from extravert to introvert and isolated.
Also the public route contains Amplis allowing people to listen to the concert also outside; this time with a different reverb, and mixed with the sounds of the city. The edges are confined by a series of very thin steel cables that act as a safety net and essentially allow for musical interaction of the user with the building.
The passive climate design is a combination of subterranean earth sheltering and venturi based ventilation system. We want to create an awareness of a passive climate design, in a way that the user experiences the forces of nature in the building. The auditorium is based under the earth with a constant ground temperature of 12°C. This cools/heats the building due to thermal lag. The public path is insulated and heated/cooled by air. In contrast, the public path is open to the climate. The emerging negative pressure point due to a venturi effect at the roof draws fresh air through the building. Sustainability is created by using eco-friendly building materials, which can be locally fabricated and constructed. In addition, the open, multifunctional built space allows for different uses in the future.
The helical structure and the piercing through makes the building an infinite loop and at the same time the ultimate network building. A place of movement and distribution and a place of permanence.

Simulation defining building borders
The orange Agents represent private people flows, the blue, public ones. The strength of each attractor can be changed, as well as the number of agents and their separation value. This allows us to simulate flows of people during different parts of the day. In further process, we will create a matrix of all these outcomes and merge them together, using the final shape to define the building border.
Structural progress
Preliminary render of the structural idea. The section is not variable yet and the structure doesn't follow the trimmed helices yet. The section (construction height) will be dependend on the span, which varies. The same goes for the floor heights so that sufficient free height is maintained as well as daylight entry. The structure will be simulated and optimised through Karamba, a structural analysis and optimisation add-on for Grasshopper.

MID-TERM REVIEW
Design starting points and research topics
The starting points for the design the building part within Group 6's voronoi cell are as follows:
1. Interactively: the building interacts mainly on the theme of (sound)waves, being sound waves primarily and electromagnetic waves (mostly light) secondarily.
2. Programmatically, the building contains a large performance space and several smaller 'absence' cells.
3. Spatially: the building addresses the theme of continuity of space
1 | Interaction: waves
The main theme of interaction is (sound)waves (frequency and volume)
WHY
Triggers emotions easily.
WHAT
Spatial and visual interpretation of sound
By using the principles of cymatics, as seen in the video below, is an interesting way of achieving this.
- Directing/amplifying/reducing sound towards 'hotspots'
- Energy harvesting (links)
- Spatial and visual reinterpertation (e.g. Cymatics)
- Wave interaction with human body
HOW
2 | Programme: performance space & absense cells
Performance space
The performance space is (programmatically) the most important important part of Group 6's building section. A performance space is, in our definition, a space where performances can take place. A performance requires
1. a performer
2. a public
3. a relation between public and performer
This relation is conventionally any kind of division: the (height) division between stage and place for spectators for example.
Types of performances:
- concert
- film projection
- theatre play
- workshop
- etc.
The goal is to find a type, combine a type, invent a dynamic type that works optimally for all performances in an integrated manner.
Absense cells
People needs special spaces to take a break from the outside world: we can call them "Absence spaces" They provide what the users are unconsciounly looking for.
relaxation (triggering brain waves to, for instance, high frequencies) meditation (triggering brain waves to, for instance, medium frequencies) chill out (triggering brain waves to, for instance, low frequencies)
This system can evolve into an "alteration space" or "distortion space" or "illusion space"
The exterior background sound (outside world) will trigger a new 4D dimension inside these cells throughout visual and hearing perceptions.
it's intended as a short stay time: from minutes to a maximum of a few hours.
3 | Spatial concept: continous space
The entire building's concept is that of a sponge. Group 6's cell continuous to work on that principle. The idea is to create one continuous shape that forms the building: floor is façade is roof. To illustrate this concept a few references are included. These concepts relate to real continuity and perceived continuity, wich are both important.
Möbius strip
The first is the Möbius strip. The Mübius strip is a 3 dimensional object that consists of one surface and has only one edge. You could go 'around' it ad infinitum. This is the sort of continuity that we are looking for.
Klein bottle
Another concept that can be referred to is the Klein bottle. The Klein bottle, like the Möbius strip also consists of one continuous surface, but whereas the Möbius strip is an object that could exist in real life, the Klein bottle is an impossible object. It cannot exist in 3 dimensions (of space). Yet the concept behind it is still interesting, because in architecture one can create illusions. When one combines both the Klein bottle principles and the Möbius strip principles a so-called Klein bagel emerges.
Penrose triangle
Lastly the Penrose triangle is to be mentioned. Like the Klein bottle, it is impossible to construct this triangle in the 3 spatial dimensions available. The interesting concept of the Penrose triangle is that the point of view of observation determines if it to be seen as such or if it is a seemingly totally different object. The play on optical illusion is very powerful.
Vertical continuity
The most interesting aspects of the continous space is probably vertical continuity. A floor is a a vertical continuity whereas a wall is a vertical discontinuity, or barrier. A way to overcome this barrier is to go diagonal, or oblique.
The oblique function of Paul Virilio and Claude perret is a conmversation between the two that talks about this topic. To quote from the description of the book on amazon.com:
"...investigated a new kind of architectural and urban order that forced the body to adapt to disequilibrium, encouraging vertigo and promoting fluid, continuous movement."
In built architecture, some references can be found. All have the oblique as the main way vertical circulation. In the pictures below there are: Kunsthal (OMA), Mercedes-Benz museum (UN Studio) and Philharmonie de Paris (unbuilt, Jean Nouvel). Some are linear, some are bended, some are multiple, intertwined oblique systems, such as the Mercedez Benz museum by UN Studio.
