  • How do I choose the right builder for my project?

    Choosing the right builder for your project requires careful research and consideration. Start by identifying builders with experience in the type of project you’re undertaking, whether it’s a new home, custom design, or renovation. Look for reviews and testimonials from past clients to gauge their reliability and quality of work.


    Request references and visit completed projects, if possible, to see the quality of craftsmanship firsthand. Ensure the builder is licensed and insured, as this protects you from potential liabilities. Transparency is key—ask about timelines, budgets, and how they handle unexpected challenges. Communication style is also crucial; a good builder will keep you informed and involve you in major decisions. Finally, get multiple quotes to compare, but don’t choose based on price alone—prioritise value and expertise.

  • What’s the difference between a custom home and a spec home?

    A custom home is designed specifically for you, with every detail tailored to your preferences, lifestyle, and needs. You work with an architect or designer to create a unique plan, and a builder constructs the home to those specifications. Custom homes offer flexibility in layout, materials, finishes, and features, but they typically take longer to build and can be more expensive due to the bespoke nature of the process.


    A spec home, on the other hand, is built by a developer or builder based on pre-designed plans. These homes are usually constructed with mass appeal in mind and are often sold during or after construction. While spec homes offer less customisation, they are typically more affordable and have shorter completion times since much of the planning is already done.



  • What should I check in a builder’s portfolio before hiring them in Shellharbour?

    When evaluating builders in Shellharbour, one of the first things to request is a detailed portfolio of their past projects. A strong portfolio should showcase a variety of work, from custom-designed homes to extensions and renovations, particularly those similar to your intended build. Focus on projects located in Shellharbour or nearby coastal areas to assess whether the builder is familiar with local design challenges, such as sloping sites, flood-prone zones, or coastal wind conditions. Look for quality in finishes, structural integrity, and how well the homes blend into their environment if you have a specific design style in mind—whether modern or eco-friendly—it helps to see examples that align with your vision. Don’t hesitate to ask for references from past clients, and if possible, request permission to view a completed home in person. Visiting a past project can reveal details that photos often don’t capture, such as workmanship quality, layout practicality, and the overall condition of the home post-construction. These insights provide peace of mind and help ensure that the builder you choose is capable of delivering the results you expect.

  • How long does it usually take to build a home in Shellharbour, and what factors can delay the process?

    The typical timeframe for building a new home in Shellharbour ranges from 6 to 12 months, depending on the complexity of the design, the builder’s schedule, and site-specific conditions. A smaller single-storey home on a level block with an existing design might take closer to 6 months, while a custom build on a challenging or sloped site could take a year or more. However, this estimated timeline can easily shift due to factors like prolonged weather disruptions (which are common in coastal areas), delays in council approvals, changes in materials availability, or trade shortages. Shellharbour’s local government planning process can take several weeks, particularly if bushfire or flood assessments are required. You should also consider seasonal slowdowns—public holidays and end-of-year breaks can stall progress if they coincide with critical stages of the build. It’s important to have an open conversation with your builder about the expected timeline, potential delays, and how they communicate project updates. A reliable builder should provide a realistic construction schedule, regular updates, and contingency plans to manage delays without compromising the quality of the build.
