EVERYTHING YOU NEED TO EXPAND AND ENHANCE YOUR HOME

Extension Options We Provide

Every extension is different. The right option depends on your property, your goals, and how much space you need. Here are the main types we build, from simple rear additions through to second-storey builds and garage conversions.

1

Rear and Backyard Extensions
Expanding into the backyard is one of the most popular approaches for Hamilton homeowners. It works well for opening up kitchens and living areas and improves indoor-outdoor flow without changing your roofline.

2

Side and L-Shape Extensions
Extending alongside your home creates new rooms or hallways without a major footprint change. A practical option when rear space is limited, and one of our most commonly requested builds.

3

Second-Storey Additions
Building upward is a smart way to add bedrooms or living zones when your section doesn't allow for a ground-floor extension. Second-storey additions can significantly increase both living space and property value.

4

Basement and Lower-Level Extensions
Where site conditions allow, extending downward creates useful living zones, rec rooms, or storage. Our team handles the structural and waterproofing requirements specific to lower-level builds.

5

Sunrooms and Conservatories
A well-placed sunroom or lean-to brings in natural light and creates a comfortable space for relaxing or entertaining year-round. A popular home addition in Hamilton for families who want more connection to their outdoor area.

6

Garage Conversions and Additions
Converting or expanding your garage into a home office, studio, or utility room adds functional area without touching your home's main footprint.
