14 to 20 months. Here's every step.
The knock down rebuild process in Sydney takes 14 to 20 months from first engagement to handover with a specialist custom builder like Marvel Homes. This page walks through each stage, what happens at each one, and what it costs in time and money, so you know what to expect before you commit. No sales pitch.

What's different at Marvel.
Paid pre-construction, not free design
We charge for the pre-con phase so the engineering and planning work has the time it needs. "Free design" almost always means rushed drawings and cost surprises later.
Fixed-price contract after pre-con. Honest, priced allowances.
Volume builders routinely use allowance line items (placeholder numbers for kitchens, bathrooms, tiling) priced low to win the job. Allowances are the single biggest source of cost blow-outs in Sydney KDR builds. We trade-quote every line we can, and where an allowance is genuinely unavoidable it is named and priced at a realistic figure, never used to hide cost.
Buildern portal and 6-month post-occupancy check-in
Daily site updates during construction, and a documented performance review six months after you move in.
