An analysis of the existing examples of densification in the study area revealed a range of typologies that have attempted to achieve this.

What is desirable? • • •

space light community

• • •

single plot 20 sub plots shared green

All plots orientated north-south Square plots are roughly 5x5m Square plots use shared green space All plots utilise roof terrace for additional private space Square subdivision assumes no on site parking therefor a car share system is in place and parking is on the street. Vehicle access is for emergency or one off use

G

Plot sizes need to be more generous to leave room for flexibility and future development Cluster housing effective as a typology but only within an off street area. Closed Courtyard plots are effective All plots need a release for movement

Assumptions:

3: Split Access Plots

study area: connection

This lead me to question what the criteria might be in order to understand, judge and ultimately create desire in a dense suburban area.

Sub plots/plots x desire total

This would then be weighed up with how many dwellings are achievable per plot.

* = unacceptable ** = poor *** = ok **** = good ***** = desirable

2: Meandering Access Plots • • •

study area: existing

However what was clear from studying these examples was that there was a lack of desirability in all cases.

Strategies marked out of 5 in same order:

i. Quality of green space ii. Proximity of green space iii. Community atmosphere iv. Daylight v. Ventilation vi. Pedestrian Friendliness vii. Privacy viii. Connectivity ix. Growth Potential x. Development Distribution

Duck Creek

littered - low water level - fast flow rate - low capacity - ignored

In order for the creek to operate as an inhabited infrastructure the existing section needs to be revitalised to become something that is worth celebrating.

lawn

Existing:

future connection

The current section is inadequate to contain the frequent flooding risk and is predominantly ignored through the area. As a result the steep banks are full of litter.

future connection

Due to the nature of the soil in the area removing the concrete section would contaminate the water table.

The boardwalk would then be cantilevered over part of the section with spacing in the floorboards to allow light to plant life below. This primary piece of landscaping integrates the series of shared courtyards along the developing site. These might manifest as a series of different uses. I have proposed an area of tiered seating that slopes down to the creek bed which also doubles as excess flood capacity while providing a place to sit in the north sun. I have also proposed an allotment area that could be rented out among the local community.

ating d se

The slope of the creek would need to be lagooned to slow the water flow down as well. This would then allow suspended reed beds to cover the concrete walls.

tiere

filtered - slow lagooning water - increased capacity - engaged

woo dlan

I am proposing to extend the existing section to increase the flood capacity while also providing some storm water retention capacity.

environmental strategy: winter

• adjustable external shading • roof encourages cross ventilation in both bedrooms • opening sizes create negative pressure for ground floor cross ventilation

• glazed north elevation and adjustable louvres enable deep winter sun penetration • potential for photovoltaics on roof

rainwater strategy: phase 3 • 66 sqm roof catchment • 10,000 litre storage capacity
