Extension Builder Newcastle | Crafted for Life

Thoughtfully designed extensions that elevate your Newcastle home with expertise and precision.

Built for How You Live

We love calling Newcastle home – the coastal breezes, indoor-outdoor living, and a strong sense of community. At Alchemy Built, we build extensions that embrace this lifestyle while anticipating your family’s future needs. Whether you already have designs or are just beginning to explore what’s possible, we’ll ensure every design decision reflects how you actually live.

Our commitment goes beyond construction; we’re building relationships with families who want a partner invested in creating spaces that enhance their lives and add lasting value to their homes.

Tailored Extension Approaches for Every Newcastle home

  • Single-Storey Rear Extensions – Perfect for expanding your kitchen, adding a home office, or creating an open-plan living area that increases your natural light and flows seamlessly with your existing layout

 

  • Double-Storey Additions – Ideal for maximising smaller blocks like those in Cooks Hill and Mayfield, allowing you to add additional bedrooms, bathrooms, or larger living areas without losing your backyard

 

  • Wraparound Extensions – A smart solution that transforms under-used side space, wrapping around the existing structure, without compromising your outdoor space.

Future-focused Living Spaces

Your extension should grow with you and your family’s lifestyle. We build with the future in mind, whether that’s accommodating multi-generational living or creating spaces for indoor-outdoor entertaining. Our commitment to sustainable building practices means we prioritise energy-efficient design, quality materials, and thoughtful construction methods that reduce environmental impact while lowering your electricity bills.

Every extension is shaped to blend seamlessly with your home’s original design while enhancing the character and charm you fell in love with. Our goal is for this new space to bring joy and add lasting value to both your lifestyle and property.

Our Extension Process

From your initial consultation to final handover, you’ll work directly with Jeff and a team who genuinely care about bringing your extension to life.

1. Discovery

We'll have an onsite consultation to discuss how you'd like to extend your home, understand how you live in your space, and talk through our approach.

2. Design & Feasibility

If you already have designs, we'll engage with your designer and complete a detailed cost analysis to ensure your project aligns with your goals and budget. If you're just beginning, we can connect you with local architects and designers who we trust and collaborate with regularly.

3. Approvals & Contract

With detailed drawings and material selections finalised, we'll manage council approvals and present you with a contract for your review and signing.

4. Construction

Work begins on your extension, with open and consistent communication, regular updates and milestone reports.Our goal is to make this process feel exciting, not stressful, so you'll always know what's happening and when.

5. Handover

We complete a final walkthrough of your home together, hand over all warranties and care guides, and stay connected for years to come.
