Aftercare: Warranty, defects liability period, and communication cadence.

FAQs about the Best Custom Home Builders
Who are the best custom home builders in Melbourne in 2025?
It depends on your block, budget and style. This guide highlights value, luxury, KDR and sustainable specialists—start with BG Construction for a balanced quality-to-price shortlist.
How much does it cost to build a custom home in Melbourne (per m² or per square)?
Budgets vary widely by site and spec. Use a base + site + upgrades framework and confirm PC/PS allowances upfront.
Is fixed-price better than cost-plus for a custom build?
Fixed-price brings certainty once documentation is complete. Cost-plus suits high-variation, design-evolving projects—just manage allowances tightly.
How long does a knockdown-rebuild take in Melbourne?
Commonly 9–14 months of construction after 2–4 months of pre-construction, depending on complexity and permit conditions.
What energy rating should I aim for in 2025?
Target 7-Star+, ideally all-electric with solar PV readiness for comfort and lower running costs.
Which builders are best for narrow or sloping blocks?
Shortlist specialists with proven void/stair strategies (narrow) or retaining/drainage detail (sloping), then inspect similar past projects.
What’s included in “turnkey” vs base price?
Turnkey adds driveways, fencing, landscaping and window coverings. Base price typically covers structure and standard inclusions; confirm line-by-line.
