How to Choose the Best House Extension Builder

Expanding your home can be an exciting yet daunting project. Choosing the right house extension builder is crucial for turning your vision into reality.

At Cameron Construction, we understand the importance of finding a skilled and reliable professional for your extension project. This guide will walk you through the essential steps to select the best builder for your needs.

How to Find and Shortlist House Extension Builders

Start Your Online Search

The internet offers a wealth of information about local builders. Websites like HiPages and ServiceSeeking provide customer reviews and ratings, giving you an initial sense of a builder’s reputation and work quality. These platforms can serve as a solid starting point for your search.

Tap into Your Personal Network

Personal recommendations often carry more weight than online reviews. Contact friends, family, and colleagues who have recently completed house extensions. Their firsthand experiences can offer valuable insights into a builder’s work ethic, communication style, and ability to deliver on promises.

Prioritize Experience in House Extensions

When creating your shortlist, focus on builders with specific experience in house extensions. Look for portfolios that showcase projects similar to your vision.

Verify Credentials and Insurance

Before proceeding with any builder, check their credentials. In Victoria, builders must be registered building practitioners to do certain work on homes. You can easily verify a builder’s registration status on the Victorian Building Authority (VBA) website. Also, confirm that they have current public liability insurance and domestic building insurance.

Request Proof of Qualifications

Don’t hesitate to ask potential builders for evidence of their qualifications and certifications. Reputable builders will readily provide this information, demonstrating their commitment to transparency and professionalism.

After completing these steps, you’ll have a solid shortlist of qualified, experienced builders for your house extension project. The next crucial phase involves evaluating their qualifications and experience in more detail.

Assessing Builder Expertise for Your Extension

Scrutinize Their Portfolio

It’s important to select a builder that not only understands your specific needs but also has the experience, knowledge and qualifications. Look beyond attractive images and examine the details of their past projects. Count the number of house extensions they’ve completed. Search for before-and-after photos. Focus on projects similar to your planned extension. Builders who have successfully completed extensions like yours will understand the nuances and challenges involved.

Probe Their House Extension Experience

Ask pointed questions about a builder’s specific experience with house extensions. Inquire about the number they’ve completed in the last year. Ask about their most challenging extension project and how they overcame it. Their answers will reveal their problem-solving skills and depth of experience.

Evaluate Team Expertise

A builder’s success depends on their team. Ask about the qualifications of the key personnel who will work on your project. Determine if they have certified architects or engineers on staff. Inquire about project managers with proven track records in house extensions. (At Cameron Construction, for example, we have a team of expert designers, engineers, and interior advisers who collaborate on each project.)

Consider Industry Recognition

Industry awards and recognition can indicate a builder’s standing among peers. It’s worth checking if the builder has received any industry awards, as this can further validate their expertise and commitment to high standards. Verify their membership in reputable industry associations (such as the Housing Industry Association or Master Builders Association). These affiliations often require adherence to high standards and ongoing professional development.

Check Client Testimonials

Client testimonials offer valuable insights into a builder’s performance. Request references from previous clients who had similar extension projects. Contact these references and ask about their experience with the builder. Try to understand how the builder handled challenges, communicated throughout the project, and delivered on their promises.

The next step in choosing the best house extension builder involves obtaining and comparing detailed quotes from your shortlisted candidates. This process will help you understand the scope of work, potential costs, and timelines for your project.

How Much Will Your House Extension Cost

Request Comprehensive Quotes

Start by asking for detailed, itemised quotes from at least three reputable builders. These quotes should break down costs for materials, labour, permits, and any additional services. A thorough quote will typically include:

• Site works, footings & slab quoted as per soil test
• Foundation work
• Framing and structural elements
• Roofing and exterior finishes
• Electrical and plumbing work
• Interior finishes (flooring, painting, etc.)
• Windows and doors
• Heating, ventilation, and air conditioning (HVAC) systems
• Specification for the hot water system

Compare More Than Just the Bottom Line

Don’t choose the lowest bid automatically. Look beyond the total cost. Compare the scope of work outlined in each quote. Does one builder include higher quality materials? Are there differences in the proposed timeline? A slightly higher quote might offer better value if it includes superior materials or a shorter completion time.

Uncover Hidden Costs

Ask each builder about potential additional costs not included in the initial quote. These might include:

• Council approval fees
• Soil testing
• Structural engineer reports
• Unexpected issues (like asbestos removal or foundation reinforcement)

The Housing Industry Association suggests budgeting an extra 10-20% for unforeseen expenses.

Understand Payment Terms

Discuss payment schedules with each builder. Typically, you’ll make payments at key project milestones. Be cautious of builders requesting large upfront payments. In Victoria, the maximum deposit a builder can ask for is 5% for projects over $20,000.

Consider Long-Term Value

Upfront costs matter, but consider the long-term value of your extension. Energy-efficient designs or higher quality materials might cost more initially but could save you money on utility bills and maintenance in the future (a consideration that aligns with Cameron Construction’s focus on quality and customer satisfaction).

Final Thoughts

The selection of a house extension builder will shape the outcome of your project. Research potential builders thoroughly, verify their credentials, and seek recommendations from trusted sources. Evaluate each candidate’s qualifications, experience, and portfolio, with a focus on their expertise in house extensions.

Obtain and compare detailed quotes from multiple builders. Consider the overall value and long-term benefits, not just the price. Look for a builder who offers transparency, quality workmanship, and clear communication throughout the process (these are qualities we strive for at Cameron Construction).
