Two homes. One block. One fixed price.

Live in one and rent the other, keep both as an investment or build alongside family. We build duplexes across Newcastle and the Hunter Valley, with weekly updates from slab to keys.

I want to live in one

Margaret St, Newcastle — Delivered On Time & On Budget Under Volatile Market Conditions

Designed by SJC Lawler Architects, this premium 3-townhouse development required strict commercial discipline to navigate severe industry-wide supply chain disruptions. Walkom Constructions successfully brought the architectural vision to life by executing a rigorous risk-mitigation strategy.

  • Proactive Procurement: Critical materials were secured and deposits placed well in advance, completely avoiding the market delays that stalled competing developments.
  • Value Engineering: Redesigned the slab system to a raft slab and optimized the framing layout. This eliminated unnecessary structural steel and drastically reduced site excavation costs without compromising design integrity.
  • Zero-Variance Cost Control: Completed exactly on the $1.4M contract budget. The project experienced zero unforeseen builder variations—the only minor changes were direct, owner-requested upgrades.

What Makes a Duplex Build Different

A split dwelling on one site carries different risks to a custom home build. Here’s a few we plan for before a price goes into a contract.

The shared wall

Fire and sound separation between homes is detailed, costed and inspected at each stage.

Two Sets of Services

Stormwater, sewer and power for two homes are scoped up front, where duplex budgets usually blow out.

Council conditions

Dual occupancy approvals come with conditions that need to be built exactly as approved.

Separate titles

Completion is planned around subdivision, so each home is ready to live in, rent or sell.

A Commitment to Direct Accountability

“I started Walkom Constructions with a simple goal. To build the sort of company I’d want to work with if I were the client.”

One that communicates honestly. Delivers quality consistently. And solves problems before they become expensive.

Today we work with homeowners and developers across Newcastle, helping deliver architecturally designed homes and medium-density developments through disciplined planning, transparent communication and practical construction expertise.

I still remain heavily involved throughout every project because I believe clients deserve direct access to the person ultimately responsible for delivering their investment.
