Custom Home Builder Sydney – Design & Construct Specialists

CETA Projects is a boutique custom home builder in Sydney specialising in design-led residential construction, including architecturally detailed homes, knockdown rebuilds, and premium build-only delivery. We work across Sydney Metro, Inner West, Eastern Suburbs and South-West Sydney with a structured process and clear communication from day one.

Best suited for: clients building $800k–$1.5m+ homes who value craftsmanship, transparency, and direct access to the builder throughout the project.

Building a Custom Home in Sydney

Sydney sites can be complex — tight access, sloping blocks, heritage overlays, council requirements and engineering constraints are common. A custom build should feel controlled and structured, not uncertain.

Where we build
  • Inner West: Five Dock, Concord, Drummoyne, Leichhardt
  • Eastern Suburbs: Randwick, Coogee, Maroubra, Kensington
  • South-West Sydney: Bossley Park, Abbotsbury, Cecil Hills, Edensor Park
  • Greater Sydney: assessed case-by-case
Common custom home scenarios
  • Knockdown rebuild on an established street
  • Vacant-land custom build
  • Architect-designed homes needing premium execution
  • Complex constraints (slope, access, retaining, stormwater)

Design & Construct (Or Build-Only) – Your Choice

We offer both design and construct and build-only delivery. If you want a single point of accountability, we can coordinate design with our partner architectural team and take the project through to completion. If you already have drawings, we can price and build from completed documentation.
