Assignment 1 - Stage 1

Building envelope

The maximum building height is 8.5 meter. The land zone is low density residential, and it is required to have a pitch or gable roof form. The maximum wall height is 7.2 meters and a maximum of 2 storeys is allowed. The floorspace ratio is 1:2 so maximum half of the site area is allowed to be floor space. The building needs to permit views from public/open space and should share views with neighbors.

Building setbacks

Buildings not related to the main structure must have a minimum setback of 2 meter. Developments must have a minimum setback of 900 mm (single storey) and 1.5 meters (two storeys). Front setback must be approximately 6.5 meters and rear must be a minimum of approximately 3.5 meters.

Site conditions

The building has views to the east. There is an afternoon sea-breese from E/NE. Cold weather coming in from S/SW, hot winds from W and rainstorms from S/SW. Trees with a light open foliage and canopy is preferred. The townscape is no. 1: Balmoral. Building should be sited with regard to topographical features minimizing cut & fill and should be sited to preserve existing significant trees, rock formations and other significant vegetation. The area of the site is 713 m², and minimum landscape area is 40.65 %. Building on a sloping site that complies with building height control can exceed maximum wall height if it does not obstruct views from neighboring property. If there is a potential view loss, council may require a maximum building height of less than 8.5 meters.

Additional design criteria’s

The new development should minimize lost view to adjoining and adjacent properties. Existing established trees contributing to amenity of the area and listed on council urban forest management register are to be retained and shall be considered in the building design. If trees are planted as a part of the development they should not unreasonably obstruct views from neighboring properties or public views. Site requires wildlife friendly garden.
