Midterm

To better analyze wall’s functions in shaping spaces and creating connections, I started with a few cubic spaces to analyze how a folded wall can define those spaces while maintaining their connections. Then I added windows and doors to created secondary connections.

My three midterm models explore the ideas of walls, spaces, and punctures in three different ways. They all started with the same 3*3*3 volumes.

The first model is analyzing the relationship between vertical walls and punctures.

Second model is exploring planes that can be folded not only around the z-axis, but also the x and y-axis, and the inverse relationship between the space enclosed and the suggested spaces above.

The third model defines the direction of the second half of my project. It is created by two planes folding into each other to intersect to define spaces.

Inside - White matt Outside - Metal reflexive

Studio 2

Then, I decided to push the idea of the Folding Walls further by investigating what a surface can produce only by folding. Demi Chang | ARCH 1102 Spring 2016

A surface has an inside and an outside. Sometimes the inside becomes the outside when the surface is folded, just like how interior spaces blend in with exterior spaces. Demi Chang | ARCH 1102 Spring 2016

Final Report

Demi Chang (dc834) Xiaohang Yan (xy296)

Process: Before making the stool, we finally decided to use oak wood instead of birch to make the stool because oak has better elasticity. Instead of using one big piece of oak to bend and cut it into four pieces, we decided to make four legs separately (since we need to fit the wood pieces into the form by hands). We did not laminate two pieces of solid wood together since that would require a level of precise cuting of the layers we can’t achive (otherwise there will be gaps around where the lamination happens).

We laminated nine pieces of white wood boards to make a wood block and cut the shape of the legs out of it for the form.

Building Technology Aalto’s Stool - in collaboration with XiaoHang Yan 16

The oak wood pieces were soaked in water for around two hours. Excessive amount of glue was applied in-between the wood pieces. Wood pieces were inserted in to the connected pieces and put into the form. Each time two legs were clamped in the mode and dried for 24 hours. For the last two legs, we used one of the legs that we previously made as a reference in the mode for better accuracy.


Unsuccessful piece: There was one leg that we put in-between two other legs in the form could not stay in shape because the glue inside of the piece could not dry. No air circulation could go through this piece. Because of that, we decided to change the design from a four-leg stool to a three-leg stool.

A round wood piece with 15� diameter was cut out of an oak plywood board, in which way that the laminated nature is matched with the legs. The four legs were nailed to the round piece.

Original Design:

After Change:

The surfaces of the legs were sanded to be smooth and have the wanted width.

Cloud Forest Demi Chang

The columns in this project serve several purposes. They pretend to be trees and let light into the interior exhibition space. They also provide support for the steel roof who is mimicking the clouds. Spaces for programs like cafe and gift shops are suspended and connected by a floating walkway. The light inside of the museum is controlled on the south facade with a double layered screen and by shading devices facing south above the columns. The entire building is built by painted white steel to help the building seem lighter, just like the airplanes displayed inside and the clouds the airplanes play with.
