Lighter and brighter look for new five-storey block at St Patrick's College Sutherland

A new, five-storey building to be built at St Patrick's College, Sutherland, has undergone a substantial makeover after concerns were raised by Sutherland Shire Council's architectural advisory panel.

Proposed external building materials have been modified to provide lighter, brighter colours with greater use of panelling and glass, resulting in "a more contemporary aesthetic", according to a council report.

Sydney South Planning Panel noted the design changes when approving, with conditions, a development application (DA) for the project which has an estimated construction cost at $13.7 million.

Meanwhile, Sydney Catholic Schools has withdrawn a separate DA for an $8.2 million upgrade of the adjoining St Patricks Primary School to "significantly change the design".

The new college block, which will replace an existing building on the corner of President Avenue and Glencoe Street, will enable student capacity to be increased from 1350 to 1500.

It will include a lower ground level car park, science labs, classrooms for Technology and Applied Studies, and general learning classrooms.

Nine of the 30 new car spaces will be allocated for the use of primary school teachers.

Approval was given for the removal of two tall Tallowood gum trees facing President Avenue.

The council assessment report said the trees were "healthy, fully mature specimens and currently provide excellent screening of this corner / existing buildings".

To compensate, additional trees will be planted at the rate of 8:1 as part of a comprehensive landscaping plan.
