PROJECT BRIEF
In recent times, the criteria for assessing architectural design have shifted from primarily structural, material and economical factors to include ecological and environmental aspects that underpin sustainable development. Central to this shift is the use of non-toxic, healthy building materials that are reused or recycled at the end of the building’s life span. Earth is the building material being researched within this design studio. Earth has been used for construction for millennia due to its low-impact, worldwide availability, thermal performance,sculpturalpotential, non-flammability, and capacity to be reused or returned to the natural cycle without harming the environment. Moreover, earth can be shaped into building components using a variety of techniques: • ramming earth • stacking earth bricks • layering earthbags • building with sod • sculpting with cob • weaving with wattel daub etc. This studio investigated the architectural potential of earth for the construction of contemporary housing units for three different scenarios depending on the location and inhabitants. The studio offered the opportunity to explore contemporary design techniques (e.g. computational & parametric design) and the application of advanced manufacturing methods(e.g. 3D printing & robotic fabri-cation). No preliminary skills are required. 33

1.1 SITE ANALYSIS We selected a location in Elliott Heads, Bundaberg, off the east coast of Queensland, away from the city’s rush. The area is surrounded by agricultural fields with sugar crops and is well known for tourism. The beach is 60 metres to the east. The site is situated in a warm and humid subtropical area in Climate Zone-2. From the east and south, most of the wind movement is seen and this area is free from the effects of floods.

1.2 MATERIALS & TECHNIQUES SOIL_ FOUND AROUND SITE
Within a 5 km radius around the site, there are 6 types of soil that are preferred for mud construction. In this region, Wattle & Duad and Rammed Earth constructions are well known. In Wattle and daub construction, we can easily source materials such as black burnt timber, bamboo, cane, straw dusk, grass, weeds and bagasse locally.

INDIGENOUS CULTURE Weaving is part of Indigenous culture, they have great abilities to make fish traps and baskets. It’s really exciting for us to understand how this weaving can produce an organic shape and hold the space at the same time. Perhaps more fascinating was how weaving without any support would generate its own structural stability. So we’re concentrating on weaving the shape of a form in order to create a habitat.

1.3 PRECEDENT STUDY TRIKA VILLA NAMPHRAE, THAILAND We have studied trika villa namphare in Thailand, an example of mud house in sub tropical climate. We can see here how open space provided between the wall and roof can give a stack ventilation system.

1.4 CLIENT BRIEF
Name Mr & Mrs Holden Mcgroin Age Holden Mcgroin 60 Pat Mcgroin 55 Occupation Former landscapers, now retired couple. Block Lot 15 Sea Esplanade, Elliotts Heads, Qld. Family 1 child married. 2 grandchildren
As landscapers we both worked and lived our live in different places and experienced various domestic environment. We both have decided to retire from our work and settle in one place where we can spend time with our child and grand children in peace. We are looking for a dynamic place which will act as a core of activity for three generation of our family with integrated circulation and funiture layout. We prefer sustainable and climate friendly approach towards design. Don’t believe in mechanical heating/ cooling, looking for organic alternative.
SPACE RECOMENDATION Multisoried house with 4 bed accomodation Dynamic spaces for different aged people. Minimum utility areas Flexible verticle circulation system Pool area with a sea view. Interctive play room 2 car parking

3.1 CONCEPT MAPPING
CONCEPT
A homogenous space generated by a material system inspired from indigenous culture that accomodate microcilmatic environment for it’s inhabitants. Our design is integration of 3 key pillars 1. A Multigenerational Habitants. 2. Contextual Micro-climate and 3. Material system – inspired by indigenous culture.

3.2 MULTI-GENERATIONAL HABITANCY Generation 1 GRAND PARENTS
Generation 2 YOUNG PARENTS
ACTIVITY MAPPING
The activity mapping for multi-generational habitants where our primary focus was on identifying the interactive activities between the different generations for cohabitation. Mapping shows functional connection and the shared interactive space among those 3 generations Generation 3 KIDS

ZONING MAPPING ITERATIONS
The spatial mapping iterations to identify the optimum solution for a multi-generational family based on the parameters – 1. Accommodating in single storey, double storey and 3 storey. 2. Accessibility and circulation. 3. View from each space and 4. Spatial Intervention. Among all, we have decided that Grandparents colour coded green should be a ccommodated on the ground floor for ease in accessibility, Young parents coded blue are accommodated on the first floor with Kids coded red and common spaces coded in grey.

MICROCLIMATE MAPPING IN FORMS
Taking into account the summer and winter solstice, we tried to evolve the form to see how various forms respond to the wind flow and also define the spaces at plan level within the shadow area. The diagrams show that an internal transitional space would be more effective for cross-ventilation. 1

We can see in a 3-dimensional view, beginning from the shape of a rectangle to a form that is well ventilated throughout. We found man-made architectural interventions such as thermal mass to be put on north and west faรงades and then to provide wider openings to be ventilated north and west through east and south. Natural intervention such as water bodies, trees, are considered to be positioned in transitional space to minimise temperature and to create a stack ventilation system through openings on the roof. We wanted to introduce a micro-climatic immersive courtyard.

3.5 PHYSICAL PROTOTYPE Studying weaving pattern
COMPUTATIONAL STUDY
In a computational framework, we have studied how various weaving patterns can be created that we can have a control to manipulate the shapes and size of the member and node location. Here we have created a weaving panel of 2 layers, separated from a certain distance and linked to a crossdirectional third weaving panel that can build a structural system of double cages integrated with a wattle and daub system and how it will communicate with different types.

UNDERSTANDING OF WEAVING BEAHAVIOUR WITH NATURAL MATERIAL
We created a 1:20 scale physical model made of bamboo that is filled with mud, with a double caged weaving structure. First of all, by anchoring it to the foundation, one layer weave pattern is created according to the shape and you can see here that the panel did not stand on itself, so we added another layer of weave pattern offset to the first one, and then both layers are cross-directionally weaved together. The outcome was optimistic that it could stand on its own. It was difficult for the next stage to render openings in such a structure. We weaved another cross-directional layer along the outline of the opening by following the existing weave. Finally, we poured mud in a thickness that could cover all layers, and it was incredible to see how 600grms of structure can hold 8 kg of wet.

WEAVING TOGETHER
The final concept emerged from blending the ideas of Multigenerational zoning layout, microclimatic intervention and double caged woven material system. The three ideas were weaved together to create a homogeneous space for the habitants. Weaving is not only creating a structure, it is also weaving the relations between the inhabitants with its surroundings.
