THESIS STATEMENT East Africa features a wide range of designed elements attributed to a history of craftsmanship and expression linked to culture and tradition. The necessity of the thesis is to incorporate the largely uninvestigated merger between modern-day architecture and the large collection of designed elements that predate it. Design manifests itself in a number of facets with regard to tangible objects which are interacted with on a daily basis across the region. These include; the built environment both residential and commercial, woven elements both worn and accessorized, embellishments at the human and architectural scale, and furniture design. Incorporating the aesthetic as well as functional qualities of the latter offers a unique quality that can be linked to the identity of growing and emerging towns, cities and entire Metropolitan regions within East Africa (and across Africa).

Serpentine Pavilion (UK) by Francis Kere
PRECEDENT STUDIES
The design is inspired by a great tree in the architect’s hometown (Gando, Burkina Faso) It features extensive overhanging steel roof canopy with transparent skin, in order to allow sunlight in while acting as a weather barrier for the open-air structure The wall system features pre-fabricated wooden blocks in triangular modules, whose assembly creates apertures which provide solid but permeable surfaces for partial visibility, adequate fenestration and circulation through out the structure Rain-water collection and a skyward connection are both accounted for at the hearth of the structure where the funnel-shaped roof channels rainwater inward into the center through an oculus The roof is detached from the walls and held up seperately in order to improve fenestration and give an appearance of lightness (floating) Mechanical lighting along the inner surface of the roof structure makes the pavilion a beacon of light at night , a symbol of story-telling and togetherness Materiality: Steel (Roof structure), Wood Slats (Roof screen), Pre-fabricated Wood blocks Source; Kere-architecture.com

Baha’i Temple (Chile) by Hariri Pontarini Architects
PRECEDENT STUDIES
‘Embodied Light’ best describes the project as it uses light for its spiritual as well as design inspiration “We continued to explore the idea of light being captured - embodied - somehow catalyzed within the material structure of the Temple. To create a building alive with light, we invented this new material utilizing cast glass, which takes light and absorbs it. The structure also has a translucent stone on the inside. When it receives just a kiss of light, a prayer is answered, and the whole piece of stone comes alive. The light does not go through it, but becomes captured within the membrane.”
- Siamak Hariri (hariripontarini.com) The form resembles the undulating topography of the Andes mountain ranges where the project is situated The structural assembly displays a textural quality similar to a rock/mountain and triangulated patterns both on the interior and exterior surfaces.

Sandibe Okavango Safari Lodge (Botswana) by Nicholas Plewman Architects
PRECEDENT STUDIES
The 24-room resort’s design is inspired by the African Pangolin; this is interpreted through the building’s curvilinear form which is created using giant laminated pine beams covered externally by Cedar shingles The architecture consists only of biodegradable materials, causes no physical harm to the adjacent surrounding and uses sustainable energy (70%) “The environmental success of the project is perhaps best judged from the fact that the area's prolific wildlife including big animals like elephants, hippos, lions and leopards have continued to live on” - Nicholas Plewman Architects Interior screens and partitions are made of woven eucalyptus laths over stiff wire

Sacred Heart Kericho Cathedral (Kenya) by John McAslan + Partners
PRECEDENT STUDIES
The project features a large pitched roof with a linear array of skylights along its apex to maximize natural lighting and probably emphasize a divine connection The roofline inclines dramatically from the entrance to the pulpit, while the exterior walls broaden similarly to create a much larger opening at the front of the church The form is inspired by the rolling hills and valleys of Kericho Timber-ribbed vaulting held up by rythmically spaced concrete arched frames creates a similar aesthetic to the wood-frame roofing in the rural context of Kericho “We believe our response is distinctive and universally welcoming. The ascending vaulted volume contained under a vast roof fuses African and ecclesiastically historic references”

How to weave HANDMADE BASKETS [VERSION 1] Place seperate (Structural) spokes in a cross-formation. String them together around the axis using TWO threads (ex. Vines) Intertwine the spokes using the threads together to spread the spokes into a radial pattern (weaving over then subsequently under) forming the BASE of the basket
After a substantial base is formed, seperate the strings and have them diverge and alternate, going over and under every spoke, to form the BODY When the spokes are substantially threaded, bend them one after the other and tuck under the adjacent spokes to complete the basket Clip off the extended spokes accordingly
[VERSION 2] Dampen a bundle of grass for flexibility and then tie it together by twining a wrap(raffia - rope) around it while leaving space for patterning threads Coil the wrapped bundle around to form the BASE of the basket To add grass, overlap the almost complete bundle with a new addition, and wrap them together using the raffia As the coiled bundles of grass begin to overlay one another while extending outward, stitch them together using the FIGURE-8 threading pattern, to form the BODY *The stitching pattern and colorization determines design of the basket The placemnt of subsequently overlapping coils determines the final shape of the basket When the basket forms into a substantial size, stitch the end of the final bundle into a tied knot Clip off the remaining thread accordingly

Organizational Strategies PASSIVE DESIGN IN TROPICAL ZONES
VENTILATION Given the nature of traditional East African architecture, several design factors had to be taken into consideration for the air circulation and exhaust due to the use of fire indoors for heating and lighting The ventilation of spaces has been successfully explored using passive design techniques which allow air intake and exhaust through strategically placed building openings They include: Cross Ventilation This requires openings placed along the opposite sides of a building plan with a fairly unobstructed path for air flow in through one and out through the other Designing for maximum ventilation through high clerestory windows, ceiling and roof vents allows for Stacked Ventilation, a process where the air circulation is channeled out through the roof 44
The principle followed is that ‘hot air rises’ hence the air filling the interior space will naturally leave upward, whereas in other cases the heating effect is induced by solar radiation directly warming up exhaust solar chimneys and creating a Stack Effect
Screen Walls The light nature of screen wall facades enable them to function as shading devices, while being design tools that allow free-flowing air and light into buildings
Landscape-channeled Breezes Trees (flora) act efficiently as wind-breakers, and similarly, they can function as directional barriers that lead wind breezes through an exterior space into a building
PASSIVE COOLING & HEATING Temperatures in tropical countries rise and fall dynamically due to a number of natural factors Designing architecture that dispenses excessive heat when required, as well as contains and distributes solar radiation when necessary is especially important A number of techniques are used in order to reduce mechanical reliance on heating and cooling, improving sustainability and reducing utility cost of buildings They include: Effective Shading Several factors are considered when designing shading elements in tropical climates due to the overhead sun, which could affect the lighting, heating and general comfort in and around buildings
46
Organizational Strategies PASSIVE DESIGN IN TROPICAL ZONES
Evaporative Cooling Water features, whether natural or artificial can be utilized to enhance cooling effects for a building, as well as reflect light into a building Elevated Flooring The air-flow beneath floors of a raised building facilitates cooling, and in some cases, protects the building materials from conditions that would cause their deteroriation Raised flooring can be done using bamboo/wood supports or hollow concrete decking Thermal Mass Temperature differences between day and night in tropical climates require designs to factor in the thermal capacity of thicker building walls (masonry/concrete) to slowly heat up during the day due to solar radiation and dispense the heat through out the night when solar radiation is absent 48
Organizational Strategies DAYLIGHTING IN TROPICAL ZONES
There is an abundance of natural sunlight in tropical climates which creates a condusive environment to factor daylighting into architectural design. However, natural sunlight is accompanied at times by adverse solar radiation which causes discomfort if it pervades into a building’s interior. Strategies can be used in order to filter in daylight while preventing heat gain. They include:
WINDOW SYSTEMS Light - deflecting Glazing (Light Shelves) Light shelves are effective devices in redirecting downward light (sunlight) toward the interior ceiling of a room. It facilitates reflection of adequate interior light while also performing as a shading device, allowing for clear glazing with minimal heat gain 50
Organizational Strategies DAYLIGHTING IN TROPICAL ZONES
Angular Reflective Glazing (Operable) Where external shading is used to reduce radiant heat gain (such as overhanging roofs), a solution is to adapt the structure of an external shade so the shade itself becomes an optical system which guides light into the building
ROOFING SYSTEMS Skylights The use of Polycarbonate (which can withstand extreme temperature, has high impact resistance, UV-coating protection and Insulation capabilities) is effective in its application, in both its transparent and translucent states Pleated Roof Systems Where external shading is used to reduce radiant heat gain (such as overhanging roofs), a solution is to adapt the structure of an external shade so the shade itself becomes an optical system which guides light into the building 52

THESIS PROJECT The extensive design project, akin to Tony Garnier’s Industrial City, is set to explore the large creative pool of design precedents and tools in order to achieve a cohesive set of designed elements at vastly different scales linked through a common design language. The first phase of the design process will heavily rely on schematic design through iterative sketches initially, based on relevant building and crafting techniques as well as design aesthetic. When clarity of design is achieved, conclusive models and drawings elaborately describing the objects will be worked on in the second and final phase of the process. The models will be crafted using materials identical to precedents, and if unavailable, visually and texturally similar materials to achieve accurate representational quality.
