The chair is designed for people who need their own peaceful space to hide and relax. The chair is put together with pentagonal shapes which ergonomically houses the human body. The geometrical structure allows the user to feel protected and cosy, almost immune to the outside world. The chair is made of oak wood and it fits for busy hotels, airports, offices and libraries.

The central theme of my degree project is the concept of solid and void, with each piece embodying a unique idea. The void element represents a container that can be filled with individual thoughts and perceptions. My goal is to create interactive objects that can be viewed from different perspectives, allowing for a personalised experience based on one’s expectations, experiences, and perceptions. I believe that the point of view from which we look at things (how we look at things) might be more important than what kind of thing it is. Through my work, I aim to induce people to change their perspectives on their daily objects and surroundings.  This thesis report is the story of my graduation work, which I worked on from December 2022 to May 2023. It contains the intentions and aims I was trying to convey through my work, the process of working on it, the difficulties I encountered along the way, and my concerns. I wrote this thesis report as a kind of working notebook or end-of-day diary, writing honestly about what I felt and learned during the process. / <p>KunSik Choi</p><p>www.kunsik.com</p>

This report discusses my exam project Entasis through four short essays. Through the project I have investigated and demonstrated how knowledge of and responsiveness to the properties of wood can generate a system for design and interior architecture. Through the project, I have described this process as a formulation of a material language, vocabulary or dialect. The metaphor of the dialect is used to highlight how materials is the language through which design and interior architecture is expressed. The project aims to demonstrate how proficiency in the language of wood makes new expressions - or dialects - possible. One important theme running through the whole work is the concept of invoking design. Through describing the objects I have built as machines, i demonstrate how the properties of wood can be an active part in the genesis of design. Design is generated by the machine through the tension between its parts. The aim of this method is to find designs that cannot be planned and to demonstrate how ideas is not outside the material - they are rather invoked from inside the material. The method is applied on different scales to generate both furniture and architectural elements.   Another important theme is Entasis - a word that during the project has changed meaning from historical curiosity to animating force. Through tensioning objects in various ways I try to demonstrate how objects can be simultaneously constructed and animated. The relation between the properties of the wood used and the non - material expression and atmosphere that the tension generates is demonstrated in an architectural system of long, tensioned pieces of wood used in the exhibition that the project was presented in.  In the ending reflection the relation between material efficiency and aesthetics is discussed. The outcome of the project is both wood - specific constructions and expressions but also general attitudes towards materiality, in the production of interior architecture and design.

I’m setting out to find beauty in the universal and common. In the used and unwanted. Giving primary value to these components, materials and techniques that are perhaps not usually considered primary or wanted in an interior context. To challenge our conception of what a beautiful piece of furniture can be. This exercise will be presented as nine chairs. Each chair has its own story, about the site and the material. We do not know what the materials of tomorrow will be. But by looking back at our predecessors we can learn a lot. They were not hindered by scarcities, they used what they had and, in my opinion, created beautiful objects that was durable enough to still be around today. Moving forward we will have to be open, and not afraid of change. It is inevitable, let’s embrace the circumstances as they come and make the best out of it then. Beauty will not be lost because we might need to use other materials. Looking back at these pre-industrial pieces, inspired by this ingenuity and creativity comes a new strain of evolution, or perhaps rather mutation. Artifacts that evoke reflection upon preferences, conventional production, the value of objects and beauty.

This report is made to create a process for urban furniture that is going to be placed in Jönköpingand other cities in Sweden. The process is created in collaboration with the company Re-invent yourfuture, which works with architecture and product design both in Sweden and other Europeancountries. The process will deliver a conceptual prototype with visualization effects, it will includesolutions for social interaction, interest and space for the citizens that live in urban spaces and big cities.

This study investigated the lateral shear resistance of multi-staple joints, static and fatigue bending moment resistances of stapled gusset-plate joints, and fatigue bending performance of full size sofa structural members in three oriented strandboard (OSB) materials. It is concluded that the lateral shear resistance capacity of multi-staple joints in OSB can be predicted with power equations including single-staple lateral resistance capacity, number of staples, and material density. The bending moment resistance of stapled gusset plate joints in OSB can be predicted by mechanical models including the lateral resistance property of multi-staple joints. The static moment capacity study of a gusset-plate joint concluded that its maximum moment resistance is 2 times of its corresponding proportional limit moment resistance. Experimental results indicated that there was no significant difference in lateral shear resistance among vertically-aligned multi-staple joints constructed of three OSB materials even though there were significant differences in lateral resistance among single-staple joints in these three materials. However, there were significant differences in lateral resistances among horizontally-aligned multi-staple joints in three OSB materials. Fatigue test results concluded that the ratio of static to passed fatigue moment capacity of gusset-plate joints was 2.6. The proposed equations reasonably estimated fatigue life of less brittle OSB materials subjected to cyclic stepped and constant fatigue loads but underestimated the brittle OSB material. The ratios of material modulus of rupture to passed fatigue stress were 2.17 and 2.25 for cyclic stepped and constant cyclic tests, respectively.
