The $1 billion mixed-use development of the former David Jones department store at the corner of Castlereagh and Market Streets in the heart of Sydney’s CBD by Cbus and Scentre Group means the MGP hydraulic team are busy working on the 22-storey luxury residential tower.

The heritage redevelopment will feature high-end retail and premium commercial within the existing building, while the new 22-storey luxury residential tower will be added above with podium gardens and views across Sydney Harbour and Hyde Park.

MGP are currently completing the hydraulic services for the residential tower, known as 111 Castlereagh. Designed by architects fjmt this prestigious tower will offer 101 residences and penthouses.  Not only offering exclusive rooftop gardens and luxurious amenities including a gym, swimming pool, cellar, outdoor terraces, MGP working with McPherson Plumbing, will ensure the hydraulic services compliment that of this luxury building.

Project due for completion: Second half of 2023

At the western edge of Sydney’s central business district, Barangaroo spans 22 hectares along Sydney’s remarkable harbour.  

Barangaroo South is an urban regeneration project located on the last major waterfront site in the Sydney central business district (CBD). At completion it will include three major office buildings, 800 residential apartments and a world class hotel situated next to waterfront parklands.

Each tower is designed to take advantage of the outstanding harbour-front location, to achieve 6 Star Green Star Design ratings and target 5 Star NABERS Energy and Water ratings.

MGP are proud to have worked with the team at Lendlease, Boone and Willard Plumbing, RPBW and PTW Architects on One Sydney Harbour.

MGP completed the detailed hydraulic design services for these benchmark luxury apartments and two penthouses, the Sky Homes.

Working closely with the team, not only did we ensure that the design provides effective and efficient services to the tower, but also that the top of the range products selected by the architects and builder deliver an outstanding service. A reflection of this striking waterfront residential tower that offers a new benchmark in luxury living.

The redevelopment of the Harbord Diggers on the Northern Beaches provided MGP with the opportunity to develop the hydraulic design for construction, along with processing the Sydney Water Building Plan Approval and Section 73 application.

This large multi dwelling and commercial site offers 96 units, speciality retail outlets, Club, indoor pool and gym, along with extensive underground parking.

The complexities of the site arose from designing and constructing the new services while working around a temporary Club still in operation.

The existing infrastructure was not sufficient to meet the demands of the new buildings notably that of water supply for drinking and fire fighting purposes. As such MGP designed water tanks which work specifically to supplement the authority water main, without putting stress on their existing infrastructure.  The design enables this large commercial and residential site to have no impact on the local authority services, and provides efficient and effective amenities to the site.

MGP undertook the hydraulic and civil design services for the addition of two levels of guest rooms in the hotel.

The contemporary design of the two new levels and roof structures meant MGP needed to work with the existing building layout and its constraints, along with council conditions in this dense urban environment. 

Within the city are restricted discharge rates and the buildings’ stormwater requires limited flow. The new roof design, that angled into the Atrium, meant MGP needed to find a solution for the stormwater runoff. The solution was an onsite detention tank located beneath the existing pool structure, and adjacent to the Atrium. This enabled run off to be collected, enabled the flow rate to be controlled into the existing council kerb and gutter without causing additional impact to the city’s infrastructure.
