S t r u c t u re The primarily structure composed of pre-cast reinforced concrete columns and beams on pile foundation, this ensures that the loads transfer through the building. In the double height spaces in some workshops, additional beams are added, on the ground floor the concrete base ensures structural transference of the loads
developed and considered since the DSIT B report to waistband earthquakes tremors and ground movement.
Th e r m a l Pe r f o r m a n c e The primary source of energy is the thermal labyrinth located in the concrete slab of the ground floor. A thermal labyrinth decouples thermal mass from the occupied space, usually by creating a high thermal mass concrete under croft with a large surface area.
To keep true to the Japanese traditional principles I have studied the layouts and functionality of the traditional houses and applied those into my design, together with the materials used in the surrounding area to keep true to the aspect of the community, I have used different layers through the use of Shoji screens and washy paper for transparency and opaque lighting as well as other materials such as timber. The timber used through the buildings is mainly for the flooring and the walls, using new and reclaimed timber from local warehouses that collect the material from demolished traditional houses from through Kyoto. The retaining wall on the ground floor provides thermal properties, which creates a controlled environment.
Heat can be gained through the summer and retained the properties in the thermal labyrinth. This will constitute the main energy source all year round, however it will mainly be used through the night if needs or during the winter.
The Shoji screens present in the building help the spaces become interchangeable as well as cross ventilating the spaces.

Concrete as a material for the ground floor was chosen for its thermal mass or heat capacity, it can be used to absorb heat to keep the interior of a building cool. Concrete has a high thermal mass with properties like brick and stone. It is possible to absorb heat from the atmosphere in warm weather and release it during cooler periods, e.g. overnight. This is known as the ‘thermal flywheel’ effect.
Wea t h e r p ro o f i n g The retaining wall on the ground floor will require weatherproof membrane because walls that protect interior spaces of a building must be considered as a higher risk and tanked accordingly Subsoil drainage will enhance the structural waterproofing design and is often a requirement by the structural engineer to reduce hydrostatic pressure on the structure. Foundation and retaining walls are constantly exposed to humidity. Waterproofing is required in order to avoid serious damage to the structure of the building and the rooms inside.

In the development of my proposal, traditional building techniques will be required especially for the bespoke timber elements such as the hanging

rooms on the second floor. CO2 emissions will be minimal especially since most timber materials will be used from local wear houses storing demolished Machiya parts. Natural cross ventilation is fully utilised where possible. Like a Machiya townhouse, the building makes full use of Shoji screens and other screens, providing the user control over the internal atmosphere. Mechanical ventilation use is at a minimum, however through the thermal labyrinth ventilation is provided to the workshop rooms and toilets.
All the materials utilised for the building have been carefully selected due to their durability properties. As highlighted in the DSIT B report there are 4 key
materials utilised through the building, reinforced concrete, timber, washy paper for the Shoji screens and glazing.
Traditional Wood Craft School The Gion Joinery Workshop is a Creative Hub which re-appropriates an unused site in Kyoto in the historical Gion Area, responding to issues of the Craft community, aiming to support the Kyoto based artists, who are suffering from lack of studio space, suitable exhibition space, affordable housing, while focusing on the wood craft community.
The prefabricated reinforced concrete beams and columns are used for their high performance and durability properties. As for the washy paper, this will be treated with was additive in order to improve their durability.
The programme outlines 3 key stages to the project’s overall development which are:
Security Gion town where the project is situating is a highly touristic area, also Japan’s crime levels are very low, taken these into considerations, the security aspect did not play a major role in the design of the building, because the whole area acts as a community.
• The project begins with the building of the Joinery Workshop School that specialises on traditional Japanese joinery. With the skills acquired in the workshops the artists together with the community can influence the second stage of the programme.
C o m m u n i ca t i o n
• The second stage involves the theatre located at the rear of the School, where the aim is to allow the performances to be transparent to the public, by carving into the theatre and exposind the performances, as well as inserting additional facilities necessary to the school. The theatre will facilitate an additional workshop that will serve as storing and maintenance for the Gion Matsuri Float.
The project is located in the heart of the historical are of Gion Town, the area is highly touristic, and it is constantly populated by both tourists and locals, thus communication of the project will not prove difficult. Since the Client is HAPS, a non-profit organisation that aim is to support Kyoto based artists who are suffering from a lack of studio space, suitable exhibition space and affordable housing as well as efficient industry networks, they can advertise the project through their already existing network as well as through the Kyoto Seika University.

• As a final stage the school will help build the accommodation for the artists, by using traditional joinery elements as detailing features of the apartments.

Through the building the structural safety of the building is considered. As it is well known that Japan suffers from earthquake tremors, this is also the case in Kyoto therefore for this design this is one of the major issues I have considered. The piling system together with the reinforced concrete structure will protect the building in times of ground movement. I am using reinforced concrete because this combination is made to utilize the compressive strength of concrete and the tensile strength of steel simultaneously. Also, my building is setback because, it produces little torsion when seismic force is applied to every story in the same direction. The structure is also required to transfer dead, live and dynamic wind loads effectively down to the ground to maintain safety and stability.
