ALEXANDER GÖSTA EDUCATION My name is Alexander Gösta. I’m currently in my first year of master in Architecture. I’m studying as an exchange student from Chalmers University, Gothenburg to Tongji CAUP, Shanghai. I got my bachelor degree in Architecture and engineering, Chalmers, one of few similar study programmes in Europe. As explained further down it’s an combination of structural engineering and architectural studies. At Tongji I study solely architecture, with focus on urban design and urban development. Hopefully this spring I will have the opportunity to implement more of my special interest of programming in my designs. I was introduced to programming in a visual interface (Grasshopper etc) at Chalmers, and feel now that this is something I would like to develop; combining engineering skills and methods in the architectural design process. China and Shanghai is providing a lot of interesting case studies. I will use my remaining time here to visit a more places and special projects.

ARCHITECTURE AND ENGINEERING The bachelor Architecture and Engineering at Chalmers is one of few similar in Europe. The analytic thinking of the engineer is combined with the free form finding methods of the architect. Five years studies will give me either a master of engineering or a master of architecture. I have a mind to take both degrees. The pie chart below shows which fields of study that is included.

EVALUATION

To create a modern place in the ancient town that generates tourism. I wanted to implement some of the great history of the site as well as make a responsible design that harmonized with the beautiful landscape. I think that my decision to spread out the buildings over the hill was a bad one in the end. I should have kept the whole complex more together in one spot. The hills are too step and changing. My solution makes for bad accessibility and take up a too large area. I also don’t like the connection with the road and the entrance to the complex which I did not work with enough.


CONTEXT Zhenyuan is located in the eastern part of the Guizhou Province at the shores of the Wuyang River. It has long been residence to the Miao people. In 202 BC the area became a county of the Han Gaozu and an important trading site. There are many tourist sites in the area of the town, like religious caves, temples, and pavilions. There is also the close relationship to the river. The ancient river architecture is unique as well as the mountain architecture. Along the river you can take boat trips and go sighting. The city government now wants to make their city more tourist friendly. At the south part of the river a site has been selected as a place for development in this direction. A large scale low fare hotel has been proposed for the site but nothing has yet been approved. We where asked to make up some alternatives. The government also requested a viewpoint from where you could stop by and view the city from the hill.

PROGRAM In contrast to the low fare hotel proposed before I think that the beautiful site need to be handled with more care. The city wants to show a modern side and adapt to tourism but at the same time mind its cultural heritage. I think there should be something that can be seen and will put a modern face to the town, but still witness the site and its culture. I want to let the Miao knowledge of building on the mountainside and the cosy village alleys shine through my design. Considering all the tourist attractions in the nearby area as well as the many hiking possibilities a hotel might be a good idea. For the less adventurous travellers the beautiful site provides for a great place for thought and meditation. Therefore a spa is suitable in connection to the hotel. To make the facility more flexible, a restaurant and conference rooms are also provided. The restaurant and conference centre is well connected with the road to be accessible without staying at the hotel. The spa is separated from both the hotel and conference centre so to really be a place for privacy and relaxation, not disturbed by others. I placed it on the opposite hillside. To connect the two sides of the facility I placed a walking bridge in between. This bridge make a strong statement in the landscape and also provides a good viewing point of the village and valley.

View from the site.

I liked the natural materials of the nearby traditional housing. Rock and wood. Stone wall as support and wood panel and timber as structure. So I chose to implement this in my design.

The site is located south of the city with view over the river.

CONCEPT Like the Miao village I wanted my facilities to climb the mountain and support itself. I imagine it to come from the valley and rise up to a more protected site, adapting to the landscape as well as to its own presence. Every part is optimizing itself for the best conditions possible. Finally, forming a new landscape on the site by its presence. To strengthen the idea of every part of the facility optimizing for its location I made it up by units. One unit is good as one hotel room. For larger or more complex requirements many units can merge and work together. On the outside appearing as many different, as the Miao village, but on the inside working as one.

BRIDGE The walking bridge is constructed by three arcs where the main arc is a framework that supports the path. The framework is covered by a wooden panel that also provides railing. This makes for a uniform appearance. The two supporting arcs pushes toward the centre of the main arc. Standing in the landscape it contradicts to the deep valley and thereby dramatizing the landscape.

EVALUATION

We were assigned to find a place in Shanghai to improve in the background of the problems with the aging society. We were first to identify problems to solve and then propose an urban design solution. To show that the street markets in the undeveloped parts of Shanghai has potential to be a lively place also in the developed city. Here could be place for sociable activities, space for meeting as well as shopping groceries. We also wanted to show that it can be safer and more organized without loosing the spontaneous atmosphere of today. We received very good comments at our final presentation. The critics liked our approach and scale. Personally I think that our actual proposal could have been more worked through. I also would liked to have looked closer into the cooperation between cars and pedestrians.


CONTEXT

In this project we have looked into what kind of demands the growing elderly society will put on the urban spaces, and what can be done to improve the current situation. To narrow the project down we have chosen a focus area. Through our research we found that the street market is a suitable place to work with. Due to its long history and tradition and that it has continued throughout generations,

all people, young as old like it. This is a place to meet and socialise as well as do your daily grocery shopping. By doing interviews and finding information from previous research we found material to put together what we call a building kit. Focusing on one street in Xiaodongmen, we hope for this building kit to be easily applicable on other, similar situations. We also hope that it might help developers to communicate with citizens about how to develop their neighbourhoods. The street markets in Shanghai usually take place in small scale areas with walk-able streets. By choosing markets as our focus area we hope to show these areas future potential and inspire to keeping such areas in the city centre.

“I like to go the Old City Park, but it’s really far to walk for me, I’m 80 years old.”

“The market would be great if there where not so many cars.”

Shanghais elderly population is increasing rapidly. Today more than 23 % is over 60 years old. In 2030 that number will be over 40 % of the population. This demographic change will most certainly have an impact on society and the urban life. Is Shanghai prepared for this change? Is the urban fabric suitable for the future activities that will want to take place?

“It’s convienient, but I would like some certain rules to make it more orginized.”

BUILDING KIT Since we through our research came to the conclusion that the market street should be a complex space that is highly adaptable depending on the occasions taking place, we wanted some way to concretize our idea. The solution became a building kit. By creating many concrete ideas of how to improve the street with small adjustments and putting everything down on a card we found a way to combine all our ideas. One card could for example hold “newspaper stand” or “adjustable market booth”. Using the master plan, we placed the cards on a suitable site and got a flexible way to discuss the situation together. This way we could make small adjustments along the design process. We think that this building kit is applicable to many similar places that can be improved with the same ideas.

AIM EVALUATION

To create a new opera house for an opera school. The building should host rehearsal rooms, workshops and dressing rooms, but also lobby, restaurant and of course the auditorium. The auditorium was required to be usable for opera, concert, musical, performances and speeches. Acoustics as well as seating needed to be very flexible. To create a spectacular building that was at the same time pragmatic and functional. The visitors should have an unique experience in the Opera while the performers should get a very functional and convenient workspace. The project was contribution to a competition that we did not win. Our critique was mainly about the somewhat unclear presentation. It was thought that our concept of two bodies meeting did not really show which made the floor plans etc. difficult to understand. Also some of our detailing was not as worked trough as it could have been. I’m a little dissapointed about missing out in these area since I think our overall idea was great and our design made exiting interior and exterior spaces.


CONTEXT Montreal is a modern metropolis. Is has brave high rises and daring architecture like the sport arenas. It is also a cultural centre for Canada. Many great culture festivals take place during the year. We think that the city should have a spectacular project that becomes another mile pole for culture in the city centre. In the context of more focus on green buildings and sustainable development we also think that the project is an opportunity for the city to create public space for recreation in the otherwise dense downtown. The opera can be a counterpart to the close by business district.

The opera is placed in close distance from the metro and bus stations at Bell Centre and the Bonaventure Station. We propose that the city make this connection more accessible. By making a park that conncets the metro stations with the opera entrance the building will be integrated with the city. We believe that the opera could be the centre piece of a new green area in the middle of Montreal. We also believe this could connect the parks at Square Chaboillez and Place du Canada making a green vein in the city.

CONCEPT 1.

We started with the rooms for visitors, giving them suitable roof hight, floor area and connections.

2.

The rooms are then covered in a shell that creates a contionious room that is more fun to experience.

3.

The shell is striped up to let the sun in and make a lighter apperance.

4.

For the workshops and rehersal rooms we added a new body, square and pragmatic in shape.

5.

Finally the shapes are merged togehter, the square one being sliced by the free form.

REHEARSAL ROOM

ACOUSTICS In order to protect the auditorium and achieve the preferable background noise levels we use several materials and screens with suitable STC-values. The traffic noise is buffered by surrounding hills and trees before it reaches the building facade. The acceptable noise levels in the large lobby are relativity high, keeping the city still present both by visual transparency and by sound. The auditorium consists of a separated body with thick double walls to reduce the remaining noise. Rooms marked in red are noisy environments where we need to take care that they don’t interfere with the main hall. They are placed in the circumference and have suitable walls. A corridor provide communication and sound buffering.

The concept for the internal wall is to combine absorption and scattering and at the same time create an interesting look. The wall consists of 20 % air bricks to increase the absorption. The bricks are placed irregularly to make a scattering surface and to avoid flutter echo on the parallel walls.

We have chosen our RT values to create a balance between clarity and richness. The reverberation time for concert is the highest, as required, with 1.75 s at 1 kHz. The high RT in low frequencies gives warmth to the sound. For Opera mode the RT at 1 KHz is 1.5 s which is preferable for singing and music together. For speech is 1 s at 1 KHz which gives it good intelligibility.

The strength of the sound is evenly distributed as well. We have achieved a good balance between singing and music with a little higher strength in singing than in music. We have a fair spaciousness with a lateral fraction of 24-42 %. The clarity for the concert setting is lower than for Opera which gives a better audibility for the music. As in the opera results the sound is evenly distributed the major part of the seating and the lateral fraction values is between 15-36 %.

Inspirational model for rehearsal room roof. How to control this design?

Start with a plane. Find points on that plane.

Translate the points randomly on the z-axis.

Connect the first with the second and the one to the right. Skip the last on every line. Make a surface between these points.

Shrink the surfaces to a desired shape depends on how much sound you want to be absorbed.

First we created the form with space in mind.

Then evaluated the surface and found points on it.

With help of the points we could create curves on the surface in the direction we wanted.

Now all that was left was to extrude the curves in the normal direction and tangent direction to create stripes with volume.


There is a large backstage area making it possible to handle many sets at once.

A large air space beneath the seats provides a slow air inlet and completely noiseless ventilation.

Architecture and optimized structures

PROGRAM

The task was to design a visitor centre for the water transport lock area in Trollhättan. There are many other tourist destinations in the area that needs to be bound together to get a comprehensive visit.

AIM

To show the visitors the locks from a new perspective and give understanding of the tremendous forces of water. Also to create an interesting construction that would inspire curiosity.

EVALUATION

My keynotes were to keep it simple and get a modern look, something for people to remember. Looking back, maybe I kept it too simple. I think there should have been more indoor area. The decision to make it two floors to make it high and notable was probalby a bad one. A redesign would probably result in many single story buildings beneath one roof.


CONTEXT This project was situated in Trollhättan, old industry town north of Gothenburg in Sweden. The town is spread out along the Göta River, the most important cargo route in Sweden in the early 20th century. It is still an impoartant route for cargo, but looking at the Falkirk canal in Scotland, tourism will propably be much more important and the main money generator in the future. The tourist boat traffic as well as the cargo traffic in Trollhättan passes by a sluice area originating from 1844. I propose that the old sluices are renovated and opened for tourist traffic. Close to this heritage I propose the wanted visitor centre. Here can be a

nice place to stop for travellers from both land and water. The visitor centre should have parking and boat docks so that it will be the starting point for experiencing the area. Guides and information should be provided. The Centre also contains facilities for researchers that can work on site and help visitors experience the area more in full. After walking around the area you continue with the boat down the sluices and really get the same journey as in the 19th century.

CONCEPT My idea was to create small buildings collected under one roof. One building for one function but all connected beneath one roof. I wanted to be in the sluice. The building should provide a really unique experience not possible without it. Therefore I created a long stairs and ramp sustained within the old inactive sluice gap. To really be a node in the area the roof received the distinct design, contradicting the stone walls and iron bars of the sluice.

! The roof rests on pillars concealed from eyes on the ground to give it a levitating feeling.

The roof gets it form from the supporting buildings and the pull of gravity against them.

Dimensions is decided with account of human scale.

DETAILS

The frame of the roof consists of two separate grids of glulam that is connected by vertical bars. It makes a thin but strong construction.

SUSPENSION

ROOF CONSTRUCTION

The roof cover consists of white-tinted permeable sheets of Plexiglas. They let through a diffused light that is beautiful whether it’s cloudy or sunny outside. The foot-walk is suspended in thin wires to make as little impact on the sluice as possible and at the same time be dramatic.

ROW HOUSES FRÖLUNDA  SUSTAINALBE FAMILY HOUSES IN GOTHENBURG COURSE YEAR EXAMINER

31 | 40

Building and environment

To design row houses for families in Frölunda, Gothenburg. It was an requirement to construct energy efficient passive houses. We also needed to adapt to all the building regulations in Sweden as accessibility etc.

AIM

To design light, multifunctional houses that would fit different needs. Another goal was to create individual looking houses fit for the modern family.

PROGRAM

EVALUATION

The projects were made in groups of three. It was my first large group project. Working in group was stimulating. The result got much better than it would have been if I made it all on my own. Our result could have gotten a cleaner outside. I’m very satisfied with all the functions we manage to fit in the relatively small area of each house. The site plan is a little to spacious considering that we wanted to make inexpensive housing.


CONTEXT The southwest part of Gothenburg is called Frรถlunda. It is mainly dominated by relatively high residential houses from the 60s. Recently Gothenburg government has started a new residential development in a smaller scale. The idea is to create some diversity in the area and attract different families. A prized new low-energy housing project has been successfully established south of the greenery area Rudalen. The second phase of the project is in development. We were to make our proposal for the new site in form of row houses for families with focus on sustainable building.

CITY CENTRE

Many fast transportation possibilities connect Tallbacken to the city core.

RUDALEN

A large recreation area lies nearby for children to play.

TALLBACKEN FRร–LUNDA TORG

Frรถlunda Torg is a shopping centre with 200 stores. This is the closest place to by groceries and other things.

CONCLUSION

The area is great for young families with children. We design houses that is attractive for such families.

CONCEPT

The classic town-house wing has dark middle parties and nice ends.

We opened a gap in the middle to let light into all the hoses and create airy spaces.

To create interesting external spaces we the skewed houses to the street.

DESIGN WORKSHOP FROM COMPUTER 3D TO PAPER MODEL As a first assignment at Tongji University I were to build a passage of 9 meters hight and 9 meters with producing feelings of release and confinement. The final hand-in consisted of a 1:20 model. This requirement really put demands on a strategy for the model construction. Space needed to be created from matter and structure. I choose to take the opportunity to learn how to create a very computerised model and try to export it into a physical model. Using Rhino to create and desired form I used grasshopper to make it printable in a laser cutter and ready for assembly.

Alexander Gรถsta


My grasshopper script consisted of two parts. Firstly I needed to make my double curved form in 2D. Using the principle of triangulating I remodeled the original design into something that can be made up from for example steel panels. Then I needed my design to be put on a spreadsheet for printing. Using the script I relocated and rotated every triangle to one plane. I also made gluing edges for the assembly. My first script printed every triangle piece by piece. This was not very good for solidity of the model and hard to glue. Finally I made every side of the columns as one cut out, only bending the paper instead of cutting it where it was not needed.

3RD PRIZE BRIDGE CONSTRUCTION CONTEST In the beginning of my second year I participated in a contest for students. The task was to construct a bridge over the campus pond with a span of 13 meters with limited materials. It should hold all for all the 8 team participants walking over the bridge. We earned third prize for an innovative and fun design. The asymmetrical design needed to be compensated by a preloaded line at the bottom. It was very learning in therms at this time of my education.

MATLAB FORM FINDING In the course Linear Algebra at Chalmers we did some workshops in MATLAB focused on graphics and visualisation. The end task was to define a multi-variable surface that could be a roof. The surface was triangulated into a triangular mesh grid. By using the partial derivative for the roof-function the grid could be relaxed into a forceoptimized form. It was fun to learn how to implement my math skills in my form finding process. Hopefully I can evolve this in the future.

z=(x.*(1-x).*(sin(4*pi*x)).*y.^(1.5).*(1-y).*14.*cos(2*pi*y)); The shape has undergone an iterative optimization function to make each bar optimal in relation to power paths.
