Rowan Streater Named in the 2026 WA Business News 40 Under 40
YOUR BUILD IS A REFLECTION OF THE PEOPLE BEHIND IT
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.
