Why work with Keycon

Why families choose Keycon as their home builder in Melbourne's western suburbs.

Keycon is a residential builder first — 200+ family homes and counting — with a commercial construction arm for clients who need both under one roof.

Proven delivery record

Since 2023, every Keycon home has been handed over on time, backed by internal project management and direct builder oversight. Drive past the homes on our Projects page — they all exist.

Fixed & transparent pricing

Every package and build is quoted at a genuine fixed price: no hidden costs, no surprise variations. What we quote is what you pay — and if something's extra, it says so before you sign.

Quality materials & craftsmanship

Trades and suppliers we've worked with across 200+ builds, and a licensed building practitioner managing every home from slab to handover. Bring your own inspector — many clients do.

Prime Melbourne locations

We build across Melbourne's growth corridors — Werribee, Tarneit, Point Cook, Truganina, Manor Lakes, Aintree — suburbs where we know the land releases, soil conditions and councils firsthand.

Customisable floor plans

Tailor your home to your block size, family size and lifestyle. Choose a single or double storey design, then adjust room configurations, facades and finishes to suit.

End-to-end support

From property search through colour selection to handover, you'll have a single point of contact for your entire build — with calls returned within one business day.

How it works

Four steps from first call to keys in hand.

01

Talk to the builder

A 15-minute call about your block, budget and family. You'll speak with our team — not a call centre — and get honest answers on what's achievable.

02

Fixed-price quote in writing

We review your block and selections, then quote a genuine fixed price that itemises what's included and what isn't. Any provisional allowance for unknown site conditions is transparent — you only pay what's actually required.

03

Build, with nothing hidden

Our licensed building practitioner oversees every stage from slab to handover. You get progress updates without chasing, and you're welcome to bring your own independent inspector at any stage.

04

Handover — and we stay reachable

You get your keys, a full warranty pack, and the builder's number saved in your phone for anything that comes up after you move in.

Guarantees that outlast the build

We come back after you move in.

Every Keycon home includes warranty inspections at 3, 12 and 24 months after handover — double the industry's 12-month standard — on top of the statutory warranties and domestic building insurance required of every registered Victorian builder. We stand behind our work after handover, not just until it.

Built for Victoria's energy standards

Every new Keycon home is designed to meet Victoria's 7-star energy rating as standard.

Orientation, insulation, glazing and sealing that cut heating and cooling bills for the life of the home — not just at inspection time.

Common questions

The answers you'd ask a friend.

Does Keycon only build homes?

+

Keycon is primarily a residential builder — house and land packages, custom homes and knockdown rebuilds — and also takes on commercial construction projects. Both are delivered by the same team, on the same fixed-price, single-point-of-contact approach.

Where does Keycon build?

+

Keycon builds across Melbourne's western suburbs — Werribee, Tarneit, Point Cook, Truganina, Hoppers Crossing, Manor Lakes and surrounding estates. Our office and most of our 200+ completed homes are in the western corridor, so we know the local estates, soil conditions and councils firsthand.

How much does it cost to build with Keycon?

+

Fixed-price house and land packages start from $525,000, depending on the suburb, block size and home design (prices current as at July 2026). Every quote itemises what's included — and what isn't — before you sign.

How long does a Keycon build take?

+

A single-storey home typically takes 6–8 months from slab to handover; double-storey takes 9–12. Permits and pre-construction add 2–4 months before the slab, and we give you a written timeline at the quoting stage.

What warranty comes with a Keycon home?

+

Every Keycon home includes warranty inspections at 3, 12 and 24 months after handover — double the industry's 12-month standard — plus the statutory warranties and domestic building insurance required of registered Victorian builders. We remain contactable after handover — the builder's number stays in your phone.
