Objectives

1. Ensure outbuildings in the residential zones and environmental living zones are appropriately sited and designed to minimise impacts on adjoining properties, the streetscape and the character of the locality;
2. Ensure the visual impact of the outbuilding is minimized and integrated into the existing surrounding environment;
3. Preserve the existing natural vegetation on site.

Controls

The following controls apply to outbuildings in the C4, R1, R2, R3 and R5 zones.

1. Outbuildings should be sited to retain existing vegetation on site and in a location where the future growth of vegetation can be retained and protected.
2. Unless otherwise approved by Council, the use of the outbuilding must be of domestic storage and hobby use only, which is ancillary to the use of the dwelling on the site.
3. Outbuildings should be sited so as they are not to encroach or impact on any existing service infrastructure, onsite sewerage management systems and associated effluent areas.

Site Requirements

1. The floor area of an outbuilding on a lot must not be more than the following:
   • 36m², if the lot has an area of less than 300m²;
   • 45m², if the lot has an area of 300m² but less than 600m²;
   • 60m², if the lot has an area of 600m² but less than 900m²;
   • 100m², if the lot has an area of at least 900m².
2. The maximum height of an outbuilding or alterations and additions to an existing outbuilding must not be more than 4.8m above ground level (existing)
3. Despite sub clause (5) above, a one storey structure with an attic above is permissible provided the height does not exceed 5.4m and amenity to adjacent sites is maintained and the roof pitch, of the building, must not exceed 45 degrees.
4. Despite sub-clauses 5 and 6 the maximum height of an outbuilding or alterations and additions to an existing outbuilding must not be more than 4.5m above ground level (existing) for 121 Raby Road, Leppington.
5. Stormwater discharge must be disposed of solely within the property boundary without causing any nuisance to the adjacent properties.
6. For outbuildings greater than 20m² in floor area, stormwater must be collected and discharged to:
   • Existing onsite stormwater lines; or
   • To a collection tank with an overflow connected to the existing onsite stormwater lines.
   • Absorption trenches or existing watercourse as deemed suitable by Council.
7. All outbuildings must comply with the cut and fill requirements within Part 4 of this DCP.

Setbacks

1. All outbuildings must be planned and organized in a group and must be located behind the building line, so it is predominantly hidden from view from the public domain.
2. All outbuildings must comply with the relevant outbuilding setback provisions within State Environmental Planning Policy (Exempt and Complying Development Codes) 2008.
3. Greater setbacks may be required to minimize any adverse impacts on the amenity of adjoining residents due to the proposed use of the outbuilding.

Building Design and Style

1. The roof pitch for any outbuilding must not exceed 36 degrees.
2. The external wall cladding of outbuildings should be of masonry, metal sheet or other approved material which is compatible with the surrounding development in terms of profile, colour and finish.
3. The roof cladding of outbuildings should be of tiles, metal sheet or other approved material which is compatible with the surrounding development in terms of profile, colour and finish.
4. The colours of roof and wall cladding should generally be of low reflective natural earth and vegetation tones.

NOTE: The external materials should be constructed of non-combustible materials if the outbuilding is located on bush fire prone land.
