ITEM 1010. MakerspaceThe layout of the Makerspace is compromised by the addition of the B99 service vehicle space. City staff recommend that any additional space required for servicing to be reallocated from the gym area.

RESPONSESpace on the ground floor is constrained due to the servicing and back house requirements for four building occupants (Student Accommodation, Social Housing, Makerspace, Gym). The B99 space has been co-located with the loading dock to consolidate similar uses and to limit the quantity of vehicular entries on the facade.

Active frontages have been maximised where possible. The gym area on ground floor is relatively modest in space serving as the gym lobby, reception and vertical circulation space. Re-allocating area from the gym for the B99 space would reduce the active street frontages.

The Makerspace plan diagram (right)demonstrates a potential layout that prioritises the active functions along the frontages to Botany Road and Church Yard. We anticipate the Makerspace area behind the B99 parking space will be used for ancillary functions such as toilets and storage.

RESPONSEThe design of the building ends have been developed in response to feedback from the DRP to ensure the facade design to these elevations are highly considered.

We believe the proposed design has a considered balance between built form articulation, fenestration and architectural expression through the expressed grid frame.

We have avoided pattern making through a variety of panel colours, instead favouring a more simple, elegant approach in keeping with the overall building architecture.

ITEM 1616. ParapetThe height of the parapet on Building 3 identified in the image below should be extended from RL 87.35 to RL 88.9 to conceal views of the solar panels from the surrounding area whilst allowing for unobstructed solar access. All other parapets should be raised to a minimum 1.5 metres above the corresponding finished roof level, subject to mitigating any overshadowing impacts on Alexandria Park.(City of Sydney)

RESPONSEThe height of the current Building 3 parapet is designed to minimise overshadowing of Alexandria Park. Any additional height along the building edge above that shown in the SSDA drawings will increase overshadowing to Alexandria Park.

To mitigate visibility from the surrounding area, the solar panel zone is proposed to be adjusted by reducing the overall maximum height from 1.5m to 1m, and increasing the setback to the north, south and east. The diagram on the right illustrates the revised extents.

Given the revised setback and height of the panel zone, the proposed panels are not expected to be highly visible from the surrounding streets. Refer to the images on the following slides for view impact studies from the surrounding area.

RESPONSE

The Building 4 roof is proposed to have a gravel finish to maintain reasonable visual amenity. A revised setback parapet detail around the building edge to allow for a sufficient gravel depth has been presented to the DRP. Increasing the parapet to 1m high would impact the proposed building form and architectural design whilst increasing overshadowing.

A louvred enclosure over the fire stair houses the stair pressurisation plant equipmentand all other plant equipment is housed in the Level 09 plant room. This plant space has been partially sunken below the roof slab to minimise it’s visual impact.

The proposal and images on this slide were presented at DRP Presentation 13 (19th March 2021) and were accepted by the panel.

ITEM 1717. ParapetThe height of the parapet on Building 4 should be similarly increased by a minimum of 1 metre to obscure any services, exhausts, plant and the like, subject to mitigating any overshadowing impacts. This would result in an exceedance to the stage 1 building envelope but comply with the maximum RL96.9 permitted for the site. (City of Sydney)

ITEM 1919. MaterialsThe glazing selection does not appear to be clear and untinted. High performance and heavily tinted glazing is not good urban design and should not be supported(City of Sydney)

RESPONSEIn co-ordination with the facade consultant and ESD consultant, we are currently exploring a range of glass products to meet the desired building aesthetic and the required environmental performance.

Our preference is for high VLT, low reflectivity and a neutral body tint, however these preferences will need to be balanced with the required environmental performance and cost.

Whilst the final glass selection has yet to be determined, the photos and descriptions on this page demonstrate the design intent.

Building 3The glass samples above, that are currently being considered for Building 3, represent a range of tints, VLT’s and reflectivity criteria. The glass samples with X’s were rejected due to being ‘too dark’ and/or ‘too blue’.

Target specification based on glass samples:/ Clear performance vision glass with neutral body tint (not too blue or too green)/ Target range 52-66% VLT (higher VLT preferred)/ Target range 9-17% Reflectivity

Building 4The glass samples above, that are currently being considered for Building 4, represent a range of tints, VLT’s and reflectivity criteria. The glass sample with an X was rejected due to being ‘too dark’ and ‘too blue’.

Target specification based on glass samples:/ Clear performance vision glass with neutral body tint/ Target range 65-72% VLT (higher VLT preferred)/ Target range 13-18% Reflectivity


ITEM 2020. MaterialsAwning windows provide substandard amenity for occupants by minimising airflow. It is recommended that sashes or casement windows be provided instead. (City of Sydney)

RESPONSEAwning windows have been typically proposed as they enable occupants to open their windows and experience natural ventilation, whilst maintaining weather protection.

A casement or sash window window does not provide the same level of weather protection.

Sashes (double hung) windows are proposed to the windows on the western elevation of Building 4, where the windows are situated behind vertical louvres, and the operation of an awning window is not possible.

Design Responses to External Shading and Thermal Comfort/ The western elevation has a high degree of solidity - the extent of glass to the west elevation is approximately 32%- (i.e the elevation is 2/3 solid)/ An insulated colourback glass spandrel at lower level further reduces the area of vision glass/ The west facade has a considered response to shading with horizontal sunshades for the early afternoon sun and vertical shading for the middle/late afternoon sun. As shown in the plan below, the vertical shading panel extends in front of the window to further assist in shading / All studios will be fitted with an internal pull-down roller blind for students/ Performance double glazing to reduce heat transmission

RESPONSEThe design of the Building 3 tower facade has been developed through the DRP process to create a highly articulated facade that responds to different the solar conditions on each elevation.

Individually operable shading devices were considered to the western elevation, but were deemed not practically viable for student accommodation for ongoing maintenance and management reasons. Fixed shading was considered to be more appropriate and cost effective solution to shading the building.


ITEM 2323. Solar Access and External Sun Shading (Building 3)Views from the sun diagrams should be provided at the summer solstice from 8am to 5pm to demonstrate the efficacy or otherwise of the design to mitigate the heat gain from the summer sun.(City of Sydney)

RESPONSEThe diagrams below were presented at DRP Presentation 12 on 28th January 2021. The diagrams demonstrate the degree of facade shading to the windows on the west elevation of Building 3.

The ‘Summernox’ (the average of summer solstice and equinox) was considered to be an appropriate method of demonstrating the average efficacy over the full period of summer.
