Building Foundations is one of Sydney’s most respected, versatile and creative builders of beautifully-designed, superior quality living spaces.

We possess decades of experience specialising in residential and commercial custom building, renovations, extensions and modifications, and we’re renowned for our uncompromising quality, attention-to-detail, and seamless execution.

Our accomplished team approaches every build with superior skill, integrity, and flexibility, and we are passionate about working with architects and clients who challenge us with unconventional, innovative and unique projects.

Our process and meticulous planning is just as important as our execution, and our highly experienced team understands the many challenges that can present themselves to clients and architects before and during the construction process.

We not only build exceptional homes, but we also build exceptional relationships. We are genuinely excited by challenging, cutting-edge projects, and as our Managing Director Ron Garbourg says, “If an architect has taken the time to communicate their vision on paper, Building Foundations will find a way to build it. And we will build it with dedication, skill and creativity.”

At Building Foundations, we’re passionate about delivering the highest quality projects, regardless of size. We work with our valued clients and architects to undertake a variety of assignments, from minor apartment renovations to home extensions; from full residential builds to the construction of small blocks of units; from heritage listed builds and commercial builds; right through to the most complex, customised projects.

Ultimately, we take care of all construction stages, providing seamless continuity and transparency throughout the building process.

Collaborative Planning

Many of our clients choose to engage Building Foundations prior to commissioning an architect. At Building Foundations, we believe that our expertise and early input will ensure we help you potentially save money, improve the construction, execute a seamless project and achieve superior results. Our collaborative style in making slight modifications to plans early in the project is proven to reduce major issues down the track.

Building Approvals

We understand that obtaining and filing paperwork can be complex and confusing. At Building Foundations, we are experienced in liaising with strata and councils on behalf of our clients to ensure all correct documents are in place for fast approvals.

We’re happy to do the work for you!

Professional Network

We happily assist our clients by providing a long list of reputable designers, architects and consultants that will best suit their needs. Our costing model is fully transparent and all subcontractors are licensed and fully insured.

Comprehensive Support

We’re proud of every project we work on and at Building Foundations, we are committed to supporting each of our clients every step of the way, from concept to completion.
