Landmark Secures $400m Sydney Construction Push

Sydney developer Landmark Group is pressing ahead with almost $400 million of work across Macquarie Park, Dee Why and Caringbah as it chases bigger outcomes on two of the same sites.

Four construction certificates—issued between March 2 and 6—cover two apartment buildings at 3 Halifax Street at Macquarie Park, a mixed-use project at Dee Why and another at Caringbah.

Together, the projects carry a combined recorded cost of works of about $400 million.

Macquarie Park is doing most of the heavy lifting.

Two of the four certificates sit at 3 Halifax Street inside Landmark’s 1.8ha Lachlan’s Line holding, a former Landcom superlot bought in 2021 for north of $130 million.

The wider precinct sits between North Ryde and Macquarie Park and is planned for about 2700 homes, almost 6000sq m of retail and 2500sq m of community facilities.

Landmark already holds approval there for two 24-storey residential towers.

The newer, taller Building A proposal has been drawn by FJC Studio, according to planning documents. Building A would contain 234 apartments and 245 car spaces.

Building B would carry 266 apartments and 270 spaces, along with basement subdivision, a new road, tree removal and landscape works.

Next door at 5 Halifax Street, another Landmark building is already under construction after winning approval in 2023 for 304 apartments across three buildings, including a 29-storey tower.

But Halifax is no longer just an approved twin-tower play.

A fresh state application for Building A seeks to lift the tower from 24 to 46 storeys.

According to the Environmental Impact Statement, the revised proposal would add 207 apartments, taking the total to 438, add two basement levels, rise to 148m and include 850sq m of affordable housing.

Planning documents said a late-2024 Ryde planning change for 3 Halifax Street opened the way for towers up to 150m and much more floor space, in return for affordable housing and a large recreation area. Dee Why is further down the track.

Landmark’s Casa Delmar project at 4 Delmar Parade and 812 Pittwater Road sits on a 7790sq m site at the southern entry to Dee Why town centre.

It began as a council scheme before growing under the NSW government’s infill affordable housing bonus.

The larger version, approved by the NSW Independent Planning Commission in December 2024, includes 280 apartments, 43 affordable homes and four commercial tenancies.

Planning material said excavation was already under way under the earlier consent before the bigger scheme moved ahead.

Council records now show a construction certificate for the balance of works, including services from Level 1 to roof, architectural fitout and external works.

Earlier briefing material said the local consent, as modified, approved 219 apartments, four commercial tenancies and a three-level basement before the state pathway delivered the larger version.

Further south in Caringbah, Landmark has also moved ahead with its approved mixed-use project at 6-20 Hinkler Avenue and 319-333 Taren Point Road, near Sutherland Hospital in the suburb’s medical precinct.

Public planning material for a later amendment described the earlier approval as three buildings of up to nine storeys containing 288 apartments, including 44 affordable homes, with a ground-floor health services facility and three basement levels with 386 car spaces.

Landmark has since lodged a much larger plan for the broader Hinkler Avenue and Taren Point Road holding.

Planning documents identify a 9431sq m site across 16 allotments and a DKO-designed scheme for 433 apartments, including 66 affordable homes, above four basement levels.

The same material said demolition had been completed and basement excavation had commenced when the report was prepared.

It also seeks to lift the planning controls from 9m to 60m and allow far more floor space, expanding the approved 288-apartment mixed-use scheme into a proposed 433-apartment development.
