Planning strategy to address the urban sprawl challenge- medium residential density codes Flashcards
describe this plan
Design WA, a State Government initiative, has introduced a suite of policies, including the reformed Medium Density Code policy, to enhance the design quality of the built environment and create vibrant communities within the metropolitan area.
The Medium Density Code policy applies to residential buildings up to four storeys and aims to guide well-designed and well-planned medium density housing development, particularly in METRONET precincts.
what does medium density housing
Medium-density housing bridges the gap between detached suburban houses and high-rise apartments, encompassing various housing types like semi-detached houses, villas, townhouses, terrace houses, and low-rise apartments.
what is the concept of the missing middle
offering guidance for residential and community development that enhances neighborhoods and streetscapes, contributing to the state’s infill target and the construction of 376,000 new homes in the Established Residential Zone.
what did the previous infill face
Previous infill developments have faced criticism for contributing to tree canopy loss and lacking designs that positively impact neighborhoods or modern living.
describe how the plan was constructed
The revised Medium Density Codes have been developed collaboratively, involving 12 architects and building designers who created 24 schemes for common lot scenarios to analyze construction costs, feasibility, and policy improvements.
The trial revealed that departing from conventional approaches could lead to a 22% increase in housing yield, a substantial increase in canopy cover, and diverse dwelling designs for each lot scenario with minimal construction costs.
what did the 4 key elements the revised policy do
The revised policy emphasizes four key elements to encourage better-designed housing, providing more choice to meet evolving community needs, thereby addressing urban sprawl challenges and offering a sustainable alternative to peripheral city development.

what is Urban Design Measurement
Good urban design results in holistic community improvements - environmentally, economically, and socially.
Environmental factors
Medium-density codes emphasizing green spaces offer well-documented environmental benefits, enhancing the neighborhood’s ecology, character, and privacy. Local government, the community, and the design industry strongly support garden area provisions during policy development.
Increased garden space and trees provide habitat for wildlife, shade, improved stormwater management, and microclimate benefits, mitigating the urban heat island effect.
Some developers express concerns about the minimum garden size requirement and its impact on affordability, especially for lots that struggle to accommodate gardens on the northern half of the site. Nevertheless, the overall planning strategy maintains a strong focus on environmental sustainability.
economic factor
Economic Trial Findings: Design trials showed minor increases in construction costs but have broader economic benefits when considering externalities.
Externa Costs: Maintaining the current medium-density design approach incurs an estimated annual cost of $117 million to the government.
Developer Returns: Despite complexities in codes, developers can anticipate higher housing yields and returns.
social factors
Medium-density developments in Perth aim to improve access to services, jobs, and transportation options, allowing residents to stay in their beloved suburbs or purchase their first home near family and friends within a ten-kilometer radius.
The revised policy takes community concerns into account and incorporates key considerations such as usable garden space, natural light, climate-conscious design, sufficient parking, and fitting facades to maintain the neighborhood’s character and visual privacy.
These considerations are addressed through the four key elements of the policy, ensuring its social sustainability.
liveability of the plan
Liveability factors include garden areas, canopy cover for climate regulation, and improved air quality.
Reduced reliance on cars, due to proximity to transport, promotes more social engagement and improved quality of life.
Optimal living standards support flexible configurations, open plan living, and multifunctional areas.
Medium-density infill offers better service access, reduced transport costs, and diverse housing in sought-after suburbs.
