Some things are built slowly, quietly, and without a grand announcement. Mayfair is one of them. Rowan Streater started his career as a carpenter in 2015. There was no ten-year plan. There was a standard, and a commitment to holding it on every job, regardless of size or complexity. That discipline, applied consistently over a decade, is what Mayfair has grown from.

Today the business employs more than thirty people, operates across Western Australia, New South Wales and the ACT, and delivers projects spanning aged care, commercial and residential construction. Two integrated trade businesses sit within the group. The same values that shaped the early work shape every project today.

Rowan was named in the 2026 WA Business News 40 Under 40 Awards. It is an acknowledgement of where the business has come from and, just as much, of the team, clients and partners who helped build it.

The 40 Under 40 brought together young leaders from across Western Australian industries who are doing meaningful work and building something worth paying attention to.

Construction is well represented in that conversation. The complexity of what clients, aged care operators and government bodies are asking for continues to grow, and the builders rising to meet that demand are those who invested early in their people and their processes. Not just their marketing.

Reputation in this industry is built slowly. It shows up in the quality of a finished space, in a client who comes back, in a subcontractor who wants to work with you again.

Rowan's inclusion in this year's list reflects that kind of progress. The kind that compounds quietly over time.

Where Mayfair is heading

The work that excites us most sits at the intersection of care, design and construction. Projects that require more than technical ability, where the environment genuinely shapes how someone lives, recovers or ages.

The Karingal Green Penthouse. The Terraces. Wycombe Grove, a flagship location for the WA Government's Time to Think transitional care program, completed in nine months and visited by the Premier shortly after opening.

These are the projects that sharpen how we think and raise what we expect of ourselves.

The focus ahead is continued growth across aged care, medical and commercial sectors, supported by an in-house trades model that keeps quality consistent and accountability clear from the first meeting through to handover.

We are proud of this one. And grateful to everyone who has been part of the journey so far.
