Why you have received this letter

Western Australia’s planning legislation sets out statutory consultation requirements for a range of planning matters. This allows people who may be impacted by proposals and the community in general to comment on proposals.

In this instance, the application is being advertised to owners and occupiers in accordance with the City’s Local Planning Policy LP.11 – Public Consultation of Planning Proposals, as the proposal includes variations to the Residential Design Codes Volume 1; which may have the potential for the amenity of adjoining properties and the street to be impacted.

The Residential Design Codes (R-Codes) provide a basis for the management of residential development throughout Western Australia. The R-Codes have two levels of assessment; a ‘Deemed-to-Comply’ and a ‘Design Principles’ assessment. The ‘Deemed-to-Comply’ provisions of the R-Codes are prescriptive in nature whereas the ‘Design Principles’ are more performance based. Where a proposal does not achieve the ‘deemed-to-comply’ pathway requirements, the proposal is to be considered against the relevant ‘design principles’ of the R-Codes.

The following departures from the deemed-to-comply provisions are identified that may impact adjoining properties:

R-Codes Volume 1 Clause 1.1 Site Area

The R-Codes set out site area requirements for different residential development types, with the intent of controlling density of subdivision. The required average site area for multiple dwellings on the subject site is 450m² to achieve the deemed-to-comply requirements.

The applicant has submitted the proposal as two multiple dwellings however, it is considered the proposal is capable of being utilised for up to four multiple dwellings, which would comprise an average site area per dwelling of 251m², as assessed under the R-Codes.

R-Codes Volume 1 Clause 5.1.2 Street Setbacks

The R-Codes set out minimum street setback requirements for buildings to achieve the deemed-to-comply requirements. The minimum required primary street setback is 6m, with a reduction to 3m permitted provided an equal area of compensating area is provided behind the 6m setback. Essentially, a building must average a 6m setback, with a minimum of 3m permitted, to achieve the deemed-to-comply requirements.

The proposal seeks an average primary street (Second Avenue) ground floor setback of 5.95m, and an average upper floor setback of 5.89m. The undercroft garage is proposed to a minimum setback of 1.5m, with the ground floor and upper floor balconies proposed at a minimum setback of 1.5m.

R-Codes Volume 1 Clause 5.1.4 Open Space

The R-Codes set out minimum open space requirements for buildings to achieve the deemed-to-comply requirements. The minimum permitted open space on site is 50%, to achieve the deemed-to-comply requirements.

The proposal seeks an open space provision of 44.78%, as assessed under the R-Codes.

R-Codes Volume 1 Clause 5.1.6 Building Height

The R-Codes set out maximum building height requirements for buildings to achieve the deemed-to-comply requirements. The maximum permitted wall height for a concealed roof form is 7m, with the roof required to be a height of 8m, to achieve the deemed-to-comply requirements.

The proposal seeks a maximum wall height of 8.9m and a maximum roof height of 8.9m, as assessed under the R-Codes.

R-Codes Volume 1 Clause 5.3.2 Landscaping

The R-Codes set out maximum building height requirements for buildings to achieve the deemed-to-comply requirements. This is intended to provide suitable landscaping within the street setback areas of a development site. The maximum permitted impervious surfacing within the street setback area is 50%, to achieve the deemed-to-comply requirements.

The proposal seeks an impervious surfacing within the street setback area of 58.64%, as assessed under the R-Codes.
