Still have questions?

We get it—choosing the right builder is a big decision. Here are the questions we hear most often from clients before they reach out.

  • Absolutely. Our team has 15+ years of experience managing everything from Passive House certifications to intricate structural steel integration. We've successfully completed challenging renovations like heritage-listed properties and large-scale rural builds. Our qualification as Greensmart® Professionals and membership in the Sustainable Builders Alliance reflects our commitment to staying at the forefront of advanced building practices.

  • Not necessarily. Our approach prioritises smart design choices that often save money long-term—like strategic window placement for natural heating and cooling, and selecting durable materials that won't need replacing. We focus on sustainable practices that enhance performance rather than just adding expensive features. Quality and sustainability are core to how we build, not expensive add-ons.

  • We're ideal for clients across the Surf Coast, Greater Geelong, Bellarine, and Mount Beauty regions who value collaborative relationships and sustainable building practices. Whether you're planning a custom new home, large-scale renovation, or heritage property update, we thrive on projects where quality craftsmanship and environmental responsibility matter as much as the end result.

  • We start with understanding what you're after through an initial consultation, then conduct a preliminary site visit. From there, we collaborate with your architect or designer (or help you find one) to develop initial concepts. Our five-step process keeps you informed at every stage—from design development through to contract signing. We're here to help you make informed decisions, not push you into anything.
