Building knowledge, from day one

Your Budget Considered From the Beginning

We believe your construction budget should be considered from the start, not after the design is complete. By bringing design and building expertise together early, we can help you explore practical solutions, make informed decisions and develop plans with construction in mind.

Custom floorplans & drawings

Great renovations and extensions start with great design

Our custom floorplans and drawings are created around your home, your lifestyle and the way you want to live. We carefully consider layout, flow, functionality, natural light and your future needs to create a design that makes the most of your space. Whether you’re planning a complete renovation, home extension, second storey addition or indoor-outdoor transformation, SBS Building Services brings design and construction together with one experienced team.

Already have plans?

If you’ve already engaged an architect, building designer or other design professional, you don’t need to start again. We can review your existing drawings from a construction perspective, prepare an estimate and discuss the next steps required to move your project towards construction. Depending on where your project is up to, we can also assist with any remaining engineering, approvals and documentation.

  • Construction review of your drawings
  • A detailed estimate
  • Remaining engineering and approvals
  • Next steps towards construction

Starting with an idea?

You don’t need to arrive with finished plans. We start by understanding your existing home, what isn’t working and what you’d like to create. From there, our in-house designer can develop custom concepts and floorplans around your lifestyle, property and budget. As the design develops, our team can then coordinate estimating, engineering, approvals and construction.

Design that gets built

Beautiful ideas need to work in real life

Our in-house designer develops custom floorplans and drawings around your existing home, property, lifestyle, future needs and budget. We consider layout, flow, natural light and functionality alongside the practical requirements of construction, helping create a design that not only looks and feels right, but can realistically progress towards construction.

  • Layout and flow
  • Natural light
  • Functionality
  • Practical buildability

Design and build, without the juggle

Keeping every stage connected

A renovation involves many decisions and many moving parts. Keeping design, engineering, approvals, estimating and construction connected can make the entire process easier to understand and manage. Your project is considered from both a design and construction perspective as it develops, so layout, buildability, structural requirements and budget are considered together rather than as separate decisions later in the process.

  • Approvals

Designed with your budget in mind

Cost guidance before you commit

Understanding the relationship between design and construction cost early can help you make better decisions. As the concept develops, our building team can review the proposed design and provide cost guidance before you invest further in detailed documentation. This gives you the opportunity to refine the design, scope or specifications earlier, helping keep the project aligned with what you want to achieve and your overall construction budget.

  • Early cost guidance
  • Refine design and scope
  • Aligned with your budget
  • Informed decisions earlier

Why design and build

One company, one team, one point of contact

Design, estimating, engineering, approvals and construction are all coordinated by SBS Building. Keeping these stages connected means fewer handovers between separate companies, clearer communication and a team that understands the thinking behind your project as it moves from design into construction.

See your home before we build it

3D visualisation can help you understand how the design will look and feel before construction begins. It is much easier to refine a design on screen than once construction has started.

One experienced team, one point of contact

Design, estimating, engineering, approvals and construction are all coordinated by SBS Building, which means fewer handovers between separate companies.

A home built around the way you live

We take the time to understand how your family lives, what you need from the space and what matters most to you, then create a design that improves flow, function and comfort.

Design that gets built

We consider layout, flow, natural light and functionality alongside the practical requirements of construction, so the design can realistically progress to site.
