Further details of the key changes are provided below:

    Ground level
    • The car park layout has been amended to include blind isles rather than a one way circulation
       system;
    • The width of the driveways has been amended to 4m in accordance with condition 22 of the
       Decision Notice;
    • A fire separation compartment has been introduced to isolate 40 and 14 comparative car
       spaces. This change includes fire walls, monitors and fire doors;
    • A single storey fire hydrant pump room has been added at the front of the building;
    • Further details of the Stormwater 360 system and rainwater harvesting tank have been added;
    • The inclusion of an electrical store on the western of the car park;
    • The setback of the fire stairs to the eastern boundary has been reduced marginally by 0.2m
       and this continues on the remaining floors of the stairs; and
    • The original layout of the lockers, motorbike parks and bicycles has been amended.

    Level One
    • The layout of the communal space and amenities has been revised;
    • The setback of the lift to the western boundary and fire stairs have been reduced marginally to
        2m and this reduced setback continues up the balance of these elements of the building; and
    • The size of the lawn for unit 1 has been reduced.

    Elevations
    • The opening on the northern elevations of the residential building have been amended; and
    • Small amendments have been made to the design of the window openings and the car
        parking level on the eastern side of the commercial building.

    Sections
    • In order to accommodate the services within the basement and provide sufficient head room,
        the floor to ceiling height in the basement has had to be increased slightly by 200mm. This
        change has increased the height of the proposed residential and commercial buildings but
        they continue to comply with the maximum building height of 8m from natural ground level.

With regard to the proposed pump room at the front of the building, it should be noted that this is
required as there is not enough water pressure in the street, in case of a fire. The pump room also
needs to be in the south eastern corner of the site where the water connection is located. The project
team has looked at a number of ways to minimise the impact of this change on the design whilst
balancing the overriding need to provide for access to the room in the event of a fire event. As a result
the architect has looked at moving the room back into the building, moving it away from the main
building and reducing its size but it has been concluded that the proposed design is the only feasible
outcome given the constraints and amount of infrastructure in this corner of the site. As a result, the
architect had tried to ensure that the room will integrate with the overall design as much as possible
by adopting a roof line and colours that are consistent with the main building.

With regard to the potential impacts of the pump room on visibility from the exit driveway it should be
noted that the conditions of the approval restrict this to a left turn only and as such, the room will not
impact on the key sightline to the right (west). With regard to pedestrian movements, the architects
have prepared the following screen shot images to show that the driveway also complies with the
minimum sightline clearance required by AS2890.1 for pedestrian safety.
