We build architecturally designed homes that reflect your lifestyle, values, and vision.
The Construction Of Basements For Sydney Homes
Make the Most of Every Square Metre
In Sydney, where land is scarce and property values are high, basement construction is one of the smartest ways to maximise your space. Whether your block is narrow, sloping, or simply too valuable to sacrifice to build a garage or driveway parking area, a basement allows you to expand your home without reducing your outdoor living area.
Or maybe you have always wanted a wine cellar or a gym and pool area for your home.
A well designed basement adds functionality, lifestyle benefits, and resale value. With more custom built homes opting for multi-level living of up to three or even four storeys.

Why Choose Phase Projects for Your Basement Build?
Basements demand precision engineering and specialist knowledge. Done right, they add enormous value. Done wrong, they can be costly and difficult to fix. That’s why experience matters.
We’ve delivered complex basement projects across Sydney, including:
- Brighton-Le-Sands Waterfront Home: A luxury four-level residence with a basement-level home theatre, gym, and cedar-clad sauna.
- Arncliffe Duplexes: A fully excavated basement level with private garages and integrated car turntables, built on a sloping site
Every Phase Projects basement is over-engineered for safety, waterproofing, and longevity, giving you peace of mind for years to come. Read more about the benefits of building a basement.
Underground Parking Basements For Your Home
Maximise Living Space
Moving your vehicles underground frees up valuable space above for living areas, outdoor entertaining, or landscaping. It’s ideal for tight urban sites and high-value suburbs where every metre counts.
Basements are Ideal for Narrow Or Sloping Blocks
On tight sites, we can integrate car turntables so you can drive straight in, have the car rotate to face the exit, and drive straight out — no reversing required.
More Than Just Underground Parking
Basements offer far more than just additional parking.
While underground garages are ideal for maximising ground-level living space and accommodating multiple vehicles, a basement can also serve as an extension of your home’s living and entertainment areas. Depending on council regulations and your design preferences, you can incorporate:
