When people think about building a home, they often picture frames going up, bricks being laid, and the excitement of watching each stage unfold.
But here’s the truth most homeowners don’t realise:
🔥 Your build timeline doesn’t start on-site. It starts months earlier – long before construction begins.
In fact, the pre-construction phase is where most delays happen, most decisions are made, and most stress can be avoided… if you know what’s coming.
Whether you want to move in by Christmas, align with a lease ending, or simply be organised, understanding the full custom home timeline is essential.
Let’s break down what really happens before your builder ever picks up a hammer.
- The Design Phase (3–12 Months)
This is the biggest surprise for most people – and one of the most important stages in your entire build.
A quality custom home design is tailored to your block, lifestyle, vision, budget, and long-term needs. That takes time.
Here’s what happens in this stage:
- Initial design meetings
- Concept plans
- Adjustments & refinements
- Structural considerations
- Budget alignment
- Final architectural drawings
The pace of this phase depends on:
✔️ how quickly decisions are made
✔️ how many rounds of changes are needed
✔️ whether the design matches your budget
✔️ your block conditions (sloping, tight access, bushfire zones, etc.)
Most delays happen when decisions drag on or the design evolves without budget guidance.
That’s why involving your builder early is crucial – it keeps your design cost-aligned from the start.
- The Approvals Phase (1–3 Months)
Once your design is finalised, approvals begin. This part often takes longer than expected, and much of it is outside the builder’s control.
This stage may include:
- Council approvals
- Private certifier review
- Engineering documentation
- BASIX & environmental requirements
- NSW Planning Portal submissions
- Bushfire, flood, or acoustic reports
Each of these has its own processing timeline –
and even one missing document can cause weeks of delays.
This phase is smoother when all selections and design decisions are completed early, which is why we guide clients through this before contracts are signed.
- Final Selections & Documentation (2–6 Weeks)
Here’s where many builds fall apart – not on-site, but on paper.
Selections like tiles, tapware, flooring, appliances, and windows often have 10–16 week lead times.
If these aren’t finalised early, your build start date – and later, your handover date – are at risk.
During this stage your builder will:
- Lock in every product and material
- Confirm pricing with suppliers
- Prepare construction-ready documentation
- Order long-lead items
- Finalise the building contract
Once everything is signed and approved, the excitement really begins…
- Pre-Construction Setup (2–4 Weeks)
Before construction starts, your builder works behind the scenes to prepare the site and schedule your trades.
This includes:
- Booking contractors
- Ordering materials
- Setting your build start date
- Establishing safety plans
- Preparing your site for work
A custom builder (like Amaze Building) takes on only a select number of projects per year, meaning your start date is carefully scheduled to ensure quality – not rushed.
Why Timelines Blow Out – and How to Avoid It
Most delays aren’t caused by weather or trades – they happen because of:
❌ Late selections
❌ Slow decision-making
❌ Over-designed plans
❌ Missing documentation
❌ Budget misalignment
❌ Changing ideas mid-way
The good news?
Every one of these delays is avoidable with the right planning.
