Experienced Residential Builders Focused On Quality Construction
Nine in Six is a boutique Melbourne builder specialising in architecturally designed homes and complex residential construction. Built on years of hands-on experience, our business combines construction knowledge, collaborative delivery, and professional project management to deliver homes of exceptional quality.
Founded on a shared passion for quality residential construction
Nine in Six have established a reputation for creating thoughtful, enduring homes that reflect the way people truly want to live. Working across Inner Melbourne, Bayside and the Mornington Peninsula, our boutique building company specialises in custom homes, renovations and architectural extensions, bringing a calm and highly considered approach to each project.
Led by directors Andrew Simmons and Aidan O'Shannessy, we are grounded in genuine craftsmanship and a hands-on understanding of construction. A background in carpentry continues to shape the company's philosophy today — one centred on detail, honesty in materials and homes that feel both refined and deeply liveable.
We are known for projects that balance architectural ambition with warmth and restraint. Heritage homes are carefully reimagined for modern family life, while contemporary residences are designed with longevity and connection in mind. Natural light, texture and materiality are central to our work, with elements such as recycled brick, timber cladding and soft, tactile finishes used in a way that feels timeless rather than trend driven.
What sets us apart is our collaborative and highly personalised process. With direct involvement from our Directors throughout every stage, we offer a level of care and accountability that is increasingly rare within the building industry. The result is an experience that feels measured, transparent and deeply tailored — whether delivering a substantial renovation, a contemporary extension or a completely bespoke new home.
At its core, Nine in Six creates homes with a quiet confidence — spaces designed not for excess, but for lasting quality, comfort and everyday beauty.
Guided by care. Built by experience.
Nine in Six is led by Aidan and Andrew, who remain actively involved throughout every stage of the construction process. Their combined experience across complex residential construction has helped shape the company's reputation for quality delivery, strong leadership, and collaborative project management
Aidan O'Shannessy
Aidan brings a passion for building that is grounded in craftsmanship, detail, and an instinctive understanding of how people want to live. A background rooted in hands-on carpentry and complex residential construction allows him to approach each project with both technical precision and a strong appreciation for design.
His work reflects a belief that truly successful homes are not defined by excess, but by proportion, materiality, and the way spaces make people feel over time. Collaboration sits at the centre of his process — with clients, architects, and trades working closely together to ensure every detail feels resolved and intentional.
Andrew Simmons
Andrew is a highly respected builder in residential construction, shaped by years of hands-on building experience and an unwavering commitment to quality. As co-director of Nine in Six, he has become known not only for delivering refined architectural homes, but also for his warm, collaborative leadership style that underpins every project.
Deeply involved on site throughout the construction process, Andrew is recognised for his pragmatic approach, problem-solving experience, and ability to guide projects with clarity and precision. Under his direction, Nine in Six continues to create homes of enduring quality designed to stand the test of time.
