Arncliffe Duplexes with Basement Parking and Swimming Pool: Built By Phase Projects

This architecturally designed duplex development in Arncliffe blends modern family living with innovative engineering. Each home offers open-plan layouts, high ceilings, custom joinery, and a warm, natural material palette — delivering both style and practicality.

A key highlight is the fully excavated basement level, a complex build element that required precision planning, heavy excavation in rocky ground, and careful management of narrow site access. The result is a rare feature in duplex living: private basement garages with integrated car turntables, giving residents both convenience and space efficiency.

Above ground, each residence features a private swimming pool and a landscaped outdoor living area — creating an inviting space for family gatherings and entertaining. By moving vehicle storage underground, the design allows for larger living spaces and generous outdoor zones, enhancing both lifestyle appeal and long-term value.

Duplex with Basement Garage FAQ’s

Got another question? Please reach out to us!
After 20 years of building homes in Sydney, we have built all sorts of homes and dealt with all planning, design and approval scenarios!

This project goes well beyond a typical side by side duplex. Each residence includes a fully excavated basement garage, private swimming pool and landscaped outdoor living area. By placing parking underground, the design creates larger living zones above ground and allows both homes to feel more like standalone residences rather than a conventional duplex.

Car turntables allow vehicles to enter and exit the basement safely without complex reversing, which is especially important on narrow sites. They maximise usability of the garage space and make day to day access far more practical for residents.

The basement was a strategic design decision. On a tight urban site like this, underground parking frees up valuable land above ground for living space, outdoor areas and pools. It also improves privacy, reduces street dominance by garages and significantly elevates the overall quality and value of the development

Yes. Each residence has its own private basement garage, storage and direct internal access, ensuring privacy and independence for both households. The layout was carefully planned so neither home feels secondary.

The site required excavation through substantial rock, along with careful structural engineering and staged access planning due to the narrow street frontage. This level of work requires experience with basements, coordination between engineers and builders, and a clear construction sequence to ensure stability and compliance throughout the build.

In suburbs like Arncliffe, lifestyle features such as pools strongly influence buyer demand and long term value. Including a pool for each residence positions the homes at the premium end of the market and appeals to buyers looking for a complete lifestyle offering rather than a compromise.

We build right across Sydney, but much of our work is concentrated in the St Georges region, Inner West, Eastern Suburbs and down towards the Sutherland Shire. See our projects to see the builds in different suburbs

Privacy was a key consideration. The basement separation, thoughtful layout, acoustic treatments, landscaping and positioning of outdoor areas all help ensure each home functions independently, with minimal noise transfer and clear separation of spaces.

Yes, when designed and engineered correctly. Basements are particularly effective on narrow or constrained sites, allowing additional space without exceeding height limits. This project demonstrates how complex sites can be transformed into high quality outcomes.

Yes. Phase Projects specialises in complex builds including basements, narrow sites and multi level homes across Sydney. Each site is assessed individually, but this project reflects the level of engineering, planning and execution we bring to challenging duplex developments.
