Everything on a W. project runs through W.App: workflows and approvals, documents, live site cameras, the 3D model, project intelligence and every conversation with your W. team, in your pocket, every day.



Let It is our procurement marketplace, where every trade package on your project is tendered to our national network of vetted subcontractors and suppliers and compared side by side. The result is competitive, market-tested pricing on every package and procurement completed in weeks rather than months, protecting your budget and your program.
Solve It is our design resolution module, where your drawings are coordinated, clashes and gaps are identified, and design decisions are resolved before they become issues on site. The result is fewer costly variations, fewer delays and a fully resolved design that still honours the original design intent.
Pay It is our payment platform, the single source of truth for every progress payment to every trade on your project. Every claim is verified against site photos and 3D site scans of work completed, giving you full transparency over where your money goes and ensuring no one is ever overpaid.
Below is an interactive 3D scan of a W. Project under construction. These scans are completed at key stages of the build and shared with everyone involved for transparency.
Asset management, DLP and warranty: the scan is a spatially accurate as-built where every asset is pinned to its real location, so warranties, serials, service history, pinned defects and supplier and installer details sit on the house rather than a spreadsheet.
A four-level coastal residence on one of Western Australia's most prestigious streets, demonstrating W.'s systems and procurement strategy to deliver significant projects across various states at once.
A striking three-level structure with a double-storey basement on Mermaid Beach, with expansive off-form concrete walls and sleek metal façades.
A two-storey residence on a sloping site in rural New South Wales, defined by sweeping curved form, expansive glazing, deep vertical sunshades, and timber cladding.
A breath-taking three-level residence with basement, showcasing expansive off-form concrete walls, soaring five-metre sliding windows and three luxurious pools.
An exquisite restoration and contemporary evolution of a heritage residence: refined Victorian craftsmanship, sophisticated modern additions and a luxurious new basement level.

Scott founded W. with one focus: to be Australia's first national legacy private residential builder. Behind it sits 15 years experience in legacy home construction, building some of Australia's most ambitious homes.
Lachlan's portfolio over the past 15 years in the industry spans from $35 million Passivehaus to Australia 108, the country's tallest residential tower. At W. he oversees cost and contract across every project.
Ross has delivered several W. projects across multiple states, overseeing some of the most sophisticated residential builds in the country to one quality standard with client experience to match.
Matthew has been a Design Manager on multiple projects in excess of $100M with 15 years in the industry, including architectural roles at Architectus and Taylor Pressly Architects.
A dedicated project team, provided from start to finish.
Sarah joined W. three years ago after a decade at LBA. She has since managed W.South Yarra and W.Alpine through to completion, two of the most complicated projects in our portfolio.
Based in HQ, Sarah leads the client relationship and owns the head contract, project rhythm and the time component for the works.
Before moving to WA, Bailey built a portfolio across Queensland, including projects in Burleigh, Brisbane and Hedges Avenue that set suburb sales records.
Currently managing 254 Marine Parade, he will oversee both Marine Parade projects with two full-time site managers reporting directly to him.
Based in HQ, Nick owns the numbers, paperwork and commercial administration that keep the project controlled.

Case Study254 Marine Parade
Bailey leads construction delivery in WA, overseeing site teams and ensuring trades are coordinated at every stage of the build. He draws on his construction experience to plan the sequence of works, anticipate challenges and maintain quality. Detailed programming and regular progress reviews turn that approach into clear actions on site, keeping the build moving to schedule.

“Working with W. has changed our lives.”

Local · National · International
We operate at three layers:
As a first step, we can optimise local trades to perform above standard on time, cost and quality through our people and processes.
Second, we can bring in high-quality suppliers and contractors from across Australia where appropriate, using our extended network and buying power.
Third, we can leverage international supply chains where required to reduce costs further.
Layer 01 · Local · Mermaid
At Mermaid, we split the concrete structure package into individual packages for reinforcement, concrete supply, formwork and concrete placement each of which are directly coordinated by us using local suppliers and trades to optimise the quality and program while also saving approximately 25% in total compared to engaging a contractor as one bundled package.
Four direct packages, coordinated by W.
Layer 02 · National · Anderson
At Anderson the specified brick was $10 a brick. We sourced the same brick for $3 and adjusted the laying technique, taking roughly 70% out of the package with the architecture untouched.
Layer 03 · International · Canterbury
Canterbury was procured directly from the factories, internationally, against a conventional locally sourced specification. The marble below—slabs, benchtops, fireplaces, vanities—was sourced direct. The finished home set the Middle Park record for an attached terrace.
Our interests and our client's interests are aligned across every dimension of the project.
Every build is programmed to the day against a live schedule our clients can see. Our fee is fixed. We have no incentive to extend and every reason to deliver early.
Every cost is competitively tendered, benchmarked against market, and filtered through a trained financial model fine-tuned on a decade of commercial data. Our fee is fixed against a defined scope. Every dollar saved on trades protects the client's cost and our margin.
Defect-free at handover. No leaks. No unfinished work. Every stage inspected and documented against a quality system defined by national exposure and strengthened by the most cutting edge construction technology stack available. Our reputation is our pipeline.
Live site cameras streaming to your device, a private daily feed of progress and milestones, one dedicated app for all communication, documents, data, and your W. team. A build with no blind spots is a build with fewer queries to answer. Transparency serves both sides.
