MBM provided cost planning and variation assessment services for Ruby House. Our cost planning support guided the project team in aligning design and construction budgets throughout development, while our thorough variation assessments ensured all contract changes were accurately evaluated and managed to maintain budget control.

Project Background and Scope

Ruby House is a premium commercial development located on Bay Street, Double Bay, offering brand-new luxury office suites in one of Sydney’s most prestigious retail and lifestyle precincts. Designed to seamlessly blend work and wellbeing, the project features high-end interior finishes, private sunlit terraces with harbour views, and state-of-the-art amenities including concierge services, end-of-trip facilities, private shower suites, secure lockers, and saunas.
Positioned in the heart of Double Bay and just moments from the harbour foreshore and ferry wharf, Ruby House includes activated ground floor retail and hospitality, as well as access to an exclusive wellness club—delivering a sophisticated and highly connected workplace environment.

Project Challenges

Key challenges included managing budget accuracy amid high-end finishes and bespoke fit-outs, alongside coordinating cost implications of design changes in a complex, mixed-use precinct. Additionally, integrating state-of-the-art amenities and activated retail spaces required careful cost control to balance quality with commercial viability.

MBM implemented detailed and regular cost reviews to track budget alignment against evolving design and construction requirements. We worked closely with the project team to assess and negotiate variations promptly, ensuring transparent cost management. Our proactive value engineering and benchmarking helped maintain quality standards while controlling costs across all project elements.
