Why choose Double Diamond as your Sydney Home Builder
Sydney has plenty of builders. Finding one you can trust is the hard part.
Double Diamond Construction built its name doing detailed, exacting renovation work across Sydney for over 15 years. Kitchens, bathrooms, and full property transformations across Sydney’s varied block sizes and council overlays.
That track record in renovations is what pushed us to expand into new home construction, custom builds, duplex development, and knock-down rebuild projects across Greater Sydney. We expanded into new home construction with the same team and the same approach that clients already trust from our renovation work.
Double Diamond Construction works with homeowners looking for custom home builders Sydney families can trust for tailored residential projects.
Every home we build is designed around your brief, your block, and your budget. You get a builder who understands residential construction at every scale, from a bathroom fitout to a ground-up custom build, because we have delivered both across Greater Sydney for more than 15 years.
A few things clients consistently mention:
- Fixed, transparent pricing with no hidden costs

- End-to-end management covering design, Council approvals, construction, and handover
- Licensed NSW residential builder with 15 plus years of project delivery across Greater Sydney

Sydney homeowners tell us the same thing every time. Communication is what made the difference. You will always know exactly where your build is up to.
Our New Home Building Process
Double Diamond Construction manages every stage of your new home construction in Sydney, from initial feasibility through to final handover. Your project stays with the same team from feasibility through to handover:
Step 1: Initial consultation and feasibility: We start by understanding your vision, your site, and your budget. You get an honest assessment of what is achievable and a clear picture of costs before anything is committed.
Step 2: Design and approvals: Our team handles design documentation and manages your Council Development Application or Complying Development Certificate. We have worked across all Greater Sydney council areas and understand exactly what each one requires. This step alone saves our clients months of frustration.
Step 3: Construction: Your dedicated project manager oversees every trade on site. Timelines are locked in at the start and tracked throughout the build. You receive regular updates at every stage.
Step 4: Quality checks and final handover: Before you get the keys, we do a thorough walkthrough of the completed home. Everything is inspected and signed off properly. You move in knowing the job was done right.
Most new home builds with Double Diamond take between 6 and 12 months from approvals to handover, depending on design complexity and site conditions. We give you a realistic timeline from day one and stick to it.
