What we build
Four paths to a
new home build.
New home builds Perth fall into four delivery types — custom-design, modular, knock-down rebuild, or extension-led major work. Each has its own programme, cost band and contract type. We design for the block, the brief and the budget.
01 · Custom
Custom design.
Bespoke architecture for your block — site-tested orientation, custom layout, premium specification. Longest programme, highest control over outcome.
02 · Modular
Modular delivery.
Factory-built modules transported and installed on a prepared site. Faster programme, fixed cost, comparable durability when engineered to WA conditions.
03 · Rebuild
Knock-down rebuild.
Demolition of the existing dwelling, slab and rebuild on the same block — keep the location, gain a contemporary home. Council and demolition managed end-to-end.
04 · Extension
Major extension.
Where a new build isn’t the right fit — second-storey or rear-extension delivery that adds the floor area without the demolition cost. Often the smarter spend.

Modular homes Perth
Modular homes
Perth-wide —
faster build, fixed
cost.
Modular homes Perth has rapidly adopted as land prices climb and trades tighten. Factory-controlled construction, faster programme, lower variance — when engineered to WA wind and climate ratings, modular delivery rivals on-site builds for durability and finish.
When modular makes sense
Three reasons Perth homeowners choose modular over custom.
When modular makes sense
When custom is betterModular isn’t always the answer.
Steeply sloped blocks, heritage overlays, narrow access, structural complexity over single-storey — these favour custom on-site delivery.
As a builder rather than a kit-supplier, we’ll tell you upfront which path suits your block. The conversation is more useful when we’re not selling a fixed product.
Note — most of our residential work to date has been renovations, extensions and government staff housing. New-home builds and modular delivery sit within our WA Builder Licence (BC104702). If you’re at the planning stage of a new build, talk to us early about whether we’re the right fit.

Why us
Why Perth clients
brief us for new
home builds.
Four practical reasons clients pick GPD as the licensed builder for a new home. The unglamorous things that decide whether a build lands on programme and budget — or doesn’t.
01
A WA licensed builder.
BC104702 since 2023. Statutory home-warranty under the WA Home Building Act applies on residential builds over $20,000. Liability flows with the licence.
02
Builder, not a kit-shop.
Most ‘new home’ suppliers are kit shops with installer crews. GPD is a builder running modular and custom delivery in our name — defects and warranty sit with us.
03
Direct line to the builder.
Owner-operated. The builder reads every brief, signs every contract, runs every site meeting. No project-manager intermediary, no head-office bottleneck on decisions.
04
Twelve months aftercare.
Direct aftercare line for twelve months from handover, every job. Statutory warranty under the WA Home Building Act applies on top of that for the full warranty period.

How we work
Five steps from brief to handover.
Same runbook for a $50,000 facilities upgrade and a $750,000 multi-trade build — only the duration changes. Every commercial construction Perth project we run follows the same four steps.

Quality criteria
What separates good
new home builds
Perth.
The unglamorous things that decide whether a Perth new build performs for thirty years or starts to fail at year ten. None of these show in display-home photos. All of them matter.
Insurance
Statutory home warranty.
Home-warranty insurance under the WA Home Building Act applies to residential builds over $20,000. Taken out before site start — not “we’ll sort it later.”
Contract
Lump-sum, HIA standard.
HIA-standard residential building contract, lump-sum, line-itemed scope. Variations by signed change order only — no “verbal agreement” creep mid-build.
Engineering
Wind rating per block.
Engineered to AS 4055 for the wind classification of the specific block — coastal Perth differs from inland, Hills, Pilbara. Generic specs are how cheap builds fail.
Energy
7-star NatHERS standard.
NCC mandates 7-star energy rating for new builds since 2023. Insulation, glazing, orientation specified at design — not value-engineered out at quote.
Compliance
BCA & NCC current.
Built to current BCA and NCC editions. Council compliance handled by us as licensed builder, not the homeowner running approvals.
Materials
For WA conditions.
Galvanised or zinc-coated framing, UV-stable cladding, marine-grade fittings near the coast. Specified for forty-degree summers and Indian Ocean storms.
