LEARNING FROM NATURAL PROCESSES
The natural process we looked at was FLUVIAL EROSION. More specifically rock eroded by water. We observed the effects of detachment and entrainment of grains by the strong force of a flowing body of water. And in turn how in time the most efficient route is worn within the rockface as the water finds a direct path.

FORM-FINDING
Using 3ds modelling; we represented an eroded rock’s contours to produce a line drawing of the natural eroded form.

SITE WOODSTREET CARDIFF...
Testing shows decibels average the normal curb-side levels.
The site is located in a prime location within the city (and within close proximity to popilar Cardiff buildings such as the Millenium Stadium and Vue cinema.) There is plenty of transportation around the site also, meaning that there is likely to be a consistant stream of people through the site to consider when open to the public.

Draft Massing Plans, 1:1000
Physical and Digital Form-Finding Models
• Initial ideas influenced by flow; the idea of water shaping form and in turn the form determining the flow of the water (Comparing the flow of water for that of people through our site)
Site Analysis
• Little vegetation in the immediate area-provision of green spaces becomes a priority • Notable views-elevated site to optimize key views • Water-accessible on site to fully intergrate water in the scheme
Precedent Study of Zaha Hadid’s King Abdullah, House of Culture and Art
• Example of a similar concept; negative space becoming public space
Precedent Study of Barcelona Dwelling
• Porosity through a solid mass • Ground floor public realm • Elevated green spaces within mass 8..

PRECEDENT STUDY
UNIVERSITY EAST ANGLIA ACCOMMODATION - DENYS LASDEN So that all dwellings got a south-facing garden I applied a simular stepped arrangement as Denys Lasden’s university accomodation for the University of East Anglia, providing a variety of different sized dwelling units. Denys Lasden has also offset each block from each other so that views are not obstructed. I have used this in my massing and this fit nicely with the curving shape of the site.
Shadow analysis to test overshadowing from neighbouring units

TECTONIC BOARD PRODUCED BY AN AUTODESK EDUCATIONAL PRODUCT
ABOVE: Image investigating continuation of between interior/exterior, (continuing module sizes from the interior shuttered concrete levels to the exterior wooden balcony cladding.) For a unified mass with directional focus towards nature. The interior insitu strata provides opportunities for different functional requirements, (such as platforms, shelfs, seats and so on,) like an evolved natural rockface eroded by the inhabitants needs.
LASER-CUT MODEL to explore interior strata concept, by sectioning a 3DS rock formation model and stacking to emulate the effect of an eroded rock’s contours.

COPPER CLADDING • Cost effective-indefinite life-span, lightweight, cheaper than Welsh Slate, hand-made clay tiles or lead • Durable and robust, doesnt suffer underside corrosion like most metals • Environmentally friendly, fully recyclable, plenty of resources available, relatively low embodied energy • No cleaning/maintainance required • Low thermal movement • Tactile, colourful appearance
Natural development of a patina as the weathering process pregresses over a number of years. When exposed to the atmosphere, copper oxide films form changing the surface colour of copper to brown. Cupric sulphide conversion films then intersperse with the initial oxide film increasingly darkening the brown surface. Continued weathering converts the sulphide films to the basic sulphate, light green, patina.
FACADE MATERIALITY
The main idea behind the choice of facade materiality was driven by the desire for an animated facade that could be transformed by nature;
