Imperial Sydney

The project design is based on the intersection of two straight lines that represent movement systems - the 60m horizontal line of the through-site pedestrian way and the 100m vertical line of lift transport and fire egress stairs. The site is located at 4-10 Campbell Street Sydney, currently occupied by Mission Australia. All existing buildings on the site were demolished for a proposed mixed-use development, comprising serviced apartments, offices and retail. 

The Haymarket Precinct has become more desirable over recent years with the upgrading of Dixon Street, redevelopment of Paddies market, running of the light rail along Hay Street and nearby apartment developments. The Campbell Street site is well suited to reinforce the established mixed-use character of the area through active ground level pedestrian spaces, small strata offices and short-stay serviced accommodation. The project has 200 services apartments with a mix of 100 (60%) x studios, 50 (35%) x 1 beds and 50 (5%) x 2 beds – which achieves the brief mix.

The serviced apartments are accessed off a lobby from Campbell Street. 1 and 2 beds are generally located at higher levels, face south and north and are provided with balconies. Studios do not have balconies. Commercial uses comprise 5,000sqm offices and 200sqm retail. Retail is located on Campbell Street, adjacent to the through-site pedestrian way. Office floors are approx 1,000sqm and can be subdivided into smaller strata offices. The offices are accessed from a lobby on Campbell Street.

The proposal comprises three elements and related areas; a low-rise element containing 5 levels of retail and the ‘office box’, facing Campbell and Cunningham Streets with a maximum parapet height of 26 metres (RL 31.5); a mid-rise element containing 12 levels of serviced apartments with a maximum street parapet height of 60 metres (RL 66.00); a high-rise element containing 17 levels of serviced apartments with maximum parapet of 108 metres (RL 113.20); and ground level forecourt and pedestrian through-site, public way that c

The building activates Campbell and Cunningham Streets by the through-site pedestrian way, access to lobbies and retail at street level. The project incorporates a north-south pedestrian through-site, public way that connects Campbell Street and Cunningham Street and completes a pedestrian way from the Capitol Theatre to World Square.

The pedestrian way is defined as a straight line through the site that visually connects the streets at each entry. It is marked by a generous forecourt on Campbell Street and necked alley way towards Cunningham Street, with potential for ‘electric’ or pictorial art.  The 4.5 metre wide pedestrian way is an accessible pathway through the site, without any mechanical device. A gently graded ramp of 1:20 to 1:25 simulates the street condition on George and Pitt Streets.

The pedestrian way threads along the eastern boundary of the narrow site without compromising the servicing of the tower or access to the upper level offices. It required the relocation of three ‘obstacles’ approved in the Stage 1 DA:the street level substation on Cunningham Street to the basement, the apartment waste room to the western boundary at Cunningham Street and office lift core to the western boundary. Sun light access to the public domain of Belmore Park is maintained by the strict compliance of the proposal with the Belmore Park Sun Access Plane in the DCP.

The building design enhances the amenity of spaces by creating a high level of natural light into the office by south and north facing glazing and light courts in the centre of the 60 metre deep floor plate, a high level of natural light to the apartments by light courts, and east and south facing glazing, reduced heat gain to the western elevation by minimising openings and balconies to 1 and 2 bedroom serviced apartments (no balconies to studios).
