design considerations to increase setback

ITEM 7.0CONSIDERATION OF OPTIONS WHICH MAY INCREASE THE NORTHERN SETBACK OF THE TOP LEVEL OF THE BUILDING.

- THE DESIGN AIMS TO MAINTAIN THE EXISTING CEREMONIAL WALK - CEREMONIAL WALK WIDTH IS SET OUT BY AMBULANCE AND HEARSE ACCESS CLEARANCES WIDTHS.- INCREASING THE TOP LEVEL SETBACK WILL RESULT IN AN INEFFICIENT CIRCULATION STAIR DESIGN WHICH WILL CAUSE INCREASES THE TOTAL BUILDING FLOOR AREAS. TO MAINTAIN USABLE CLASSROOM SPACES WITHIN THE INNOVATION HUB, ADDITIONAL BUILDING HEIGHT AND ENVELOPE WILL BE INCREASED

CONCEPT DESIGN - FORM TESTING

OPTION STAGGERED SETBACK OPTION

PROS• COMPACT FORM REDUCING COST• END POINT OF NEW AXIS VISIBLE FROM COMMONS BUILDING• HISTORIC BUILDING AXIS CAN BE REINSTATED/RETAINED• STAGGERED SET BACKS TO UPPER LEVELSCONS• TOO HIGH COMPARED TO SITE, NEIGHBOURING RESIDENTS AND HERITAGE

BUILDING• OFFENSIVE / CONTROVERSIAL TO NEIGHBOURING RESIDENTS• NO INTERACTION WITH SITE• TOP FLOORS DISCONNECT FROM CAMPUS

STAGGERED SETBACK OPTION

• EARLY CONCEPT DESIGNS (OPTION 1) DEMONTRATES TESTING OF A STAGGERED SETBACK FORM WHICH INCREASED THE SETBACK OF AS THE BUILDING INCREASED IN HEIGHT. STARTING FROM A 5M SETBACK AT THE LOWER GROUND TO A 10M SETBACK FROM GROUND TO THREE AND A 15M SETBACK ON LEVEL 4.

• THIS OPTION REQUIRED THE BUILDING TO BE 6 STOREYS IN ORDER TO FACILITATE USABLE CLASSROOM SPACES. FOOTPRINT OF BUILDING IS COMPARATIVELY SMALLER, HOWEVER HEIGHT OF BUILDING IN GREATLY INCREASED.

DESIGN CONSIDERATIONS TO INCREASE SETBACK

6 STOREY , 15M / 10M / 5M SETBACKS FROM NORTHERN BOUNDARY

2 SETBACKS OPTION

• THE MASTERPLAN OPTION HAD LOOKED AT HAVING 7.5 METRE SETBACK FROM LOWER GROUND AND 15.5 METRE SETBACK TO UPPER LEVELS.• THIS OPTION HAD LARGER FOOTPRINT AND ALSO LARGER FRONTAGE TO NORTHERN NEIGHBOURS• HEIGHT OF THIS OPTION WAS STILL DEEMED TO HIGH IN COMPARISION TO SURROUNDING CONTEXT• LARGE BUILDING FRONTAGE TO NORTHERN BOUNDARY

5 STOREY , 15.5M / 7.5M SETBACKS FROM NORTHERN BOUNDARY


2 SETBACKS OPTION

PROS• END POINT OF NEW AXIS VISIBLE FROM COMMONS BUILDING• TOTAL HEIGHT DOES NOT EXCEED HERITAGE BUILDINGS• MATURE GUM TREES CAN BE RETAINED BENEFITING RESIDENTS AND

SCHOOLCONS• PINE TREE OF SIGNIFICANT HERITAGE VALUE NEEDS TO BE TAKEN DOWN• STEPS OF SIGNIFICANT HERITAGE VALUE NEED TO BE TAKEN DOWN• NEW AXIS DISREGARDS HISTORIC “KINKED” AXIS TO OLD COX BUILDING• 5 STOREY HIGH BUIILDING COMPROMISES VIEW AMENITY AND PRIVACY OF

NEIGHBOURING RESIDENTS


4 STOREY , 10M / 5M SETBACKS FROM NORTHERN BOUNDARY REDUCED HEIGHT WITH 2 SETBACKS OPTION

PROS• PINE TREE OF SIGNIFICANT HERITAGE VALUE RETAINED• REDUCTION OF HEIGHT TO 3-4 STOREYS• COURTYARD SPACE BENEFITS (OUTDOOR SPACE AND LIGHT TO INTERNAL SPACES)CONS• LARGER FOOTPRINT• DEMOLITION OF SMALL PORTION OF ADJACENT “BROTHER QUENTIN BUILDING”

(POTENTIALLY)• LARGE NORTHERN FRONTAGE OF UPPER LEVELS



2 SETBACKS OPTION WITH LARGER FOOTPRINT & REDUCED HEIGHT

• THE 4 STOREY OPTION WAS TESTED WITH 5M SETBACK FOR LOWER GROUND AND 10M SETBACK FOR UPPER LEVELS• FOOTPRINT OF THE BUILDING WAS INCREASED TO ACCOMODATE A LOWER OVERALL BUILDING HEIGHT• LARGE BUILDING FRONTAGE TO NORTHERN BOUNDARY


PROPOSED CONCEPT DESIGN FORM

24m

9m

5m

4 STOREY, 9M / 5M SETBACKS FROM NORTHERN BOUNDARY

2 SETBACKS OPTION WITH REDUCED NORTHERN FRONTAGE

• THE UPPER LEVELS WERE PROPOSED TO BE ROTATED 90 DEGREES TO REDUCE FRONTAGE TO NORTHERN BOUNDARY• MAINTAINED EXISTING CEREMONIAL WALK ON GROUND LEVEL• REDUCED HEIGH AND REDUCED NORTHERN FRONTAGE DESIGN ALLOWED FOR LESS VISUAL IMPACT TO NEIGHBOURS

MAINTAING THE EXISTING CEREMONIAL WALK AXIS

• THE EXISTING CERMONIAL WALK TOWARDS TO CEMETERY WAS MAINTAINED TO PROVIDE PEDESTRIAN CONNECTION THROUGHOUT THE CAMPUS WHILST ALLOWING ENTRY PROCESSIONS TO BE CONDUCTED BY THE COLLEGE IN THE EVENT OF A FUNERAL SERVICE.

• CEREMONIAL WALK REQUIRES VEHICULAR ACCESS AND MINIMUM SWEPT PATHS• WORKSHOPS ON LOWER GROUND OPEN AWAY FROM NORTHERN BOUNDARY TO REDUCE NOISE • MOVING THE CERMONIAL WALK SOUTH WOULD NOT BE POSSIBLE TO LOCATION EXSTING BR QUENTIN BUILDING, WORKSHOP COURTYARD

ORIENTATION AND VEHICULAR ACESS REQUIRED ON SITE.

WORKSHOP COURTYARD ORIENTATED AWAY FROM NEIGHBOURS

EXISTING BR QUENTIN BUILDING

AMBULANCE AND HEARSE ACCESS TO CEMETERY

INCREASE TO BUILDING ENVELOPE DUE TO INCREASE SETBACK

• WHILST MAINTAINING THE CEREMONIAL WALKWAY, TO INCREASE THE SETBACK OF THE UPPER LEVELS WOULD REQUIRED A CHANGE IN THE INTERNAL CIRCULATION OF THE BUILDING

• CURRENTLY THE STAIR SERVICES LOWER GROUND TO LEVEL 2 EFFICIENTLY.
