Whether your family is growing, your lifestyle has changed, or your home simply no longer meets your needs, alterations and additions can transform the way you live without the cost and disruption of moving.

At Gleeson Build, we specialise in high-quality home alterations and additions across Sydney’s Eastern Suburbs and Sutherland Shire. From opening up existing floorplans and reconfiguring internal spaces to constructing seamless extensions, we create practical, well-designed homes that feel like they have always been that way.

With a background in carpentry and extensive experience delivering residential building projects, we manage every stage of the process with a focus on quality workmanship, clear communication, and attention to detail.

Tailored Home Extensions and Alterations

Every home is different, which is why we take the time to understand how you want to live in your space before construction begins.

Our alterations and additions services include:

• Ground floor extensions
• Rear home extensions
• Additional bedrooms and living spaces
• Open-plan kitchen and living transformations
• Structural wall removals
• Internal reconfigurations
• Second-storey additions
• Home office and studio spaces
• Laundry and utility room upgrades
• Outdoor living integrations

Our goal is to ensure every new space integrates seamlessly with the existing home, both structurally and aesthetically.

Maximising Space, Light and Functionality

Many older Sydney homes have great character but can feel disconnected from modern living requirements. Through carefully planned alterations and additions, we can improve natural light, increase functionality, and create better flow throughout the home.

Whether it’s opening up dark interiors, connecting indoor and outdoor living areas, or creating additional room for a growing family, we deliver practical solutions that add long-term value to your property.
