Building Sloping Block Dream Houses

In Sydney, land is scarce and often far from flat.
That’s where Phase Projects comes in. As expert sloping block builders, we specialise in designing and delivering custom homes that work with your land, not against it.
From narrow urban sites to steep coastal blocks, we unlock the potential of difficult terrain with solutions that add space, value, and liveability.

Why Build on a Sloping Block?

Building on a slope isn’t a compromise, it’s an opportunity.
With the right design, sloping sites can deliver:

  • Multi-level homes with panoramic views
  • Walk-out basements for parking or lifestyle spaces
  • Improved natural light and airflow
  • Unique architectural character
  • Long-term resale value in sought-after locations

Our Speciality Is Creating Basements for Sloping Blocks

Where other builders see obstacles, we see possibilities.
Basements are one of the smartest ways to maximise a sloping block, giving you:

  • Secure underground parking, even on tight-access streets
  • Lifestyle additions like home theatres, gyms, saunas, or wine cellars
  • Extra storage without taking away from living or outdoor space
  • Stronger foundations, engineered for stability and long-term durability

We’ve delivered basements in some of Sydney’s most complex projects, including multi-level homes and duplexes on narrow streets with difficult excavation requirements.
