Ground Floor Additions St Clair
Who We Are
Here's how we work: we design and build residential ground-floor additions that fit your life. We do ground-level extensions with open spaces. We also handle custom ground-floor additions for small block homes. Our solutions are reliable and won't break the bank. Our builders have licenses and insurance. We take care of everything from start to finish. That includes getting approvals, drawing plans, building, and handing over the keys.
Thinking about a ground-floor home renovation in St Clair? We give you a fixed price upfront. We tell you exactly how long it will take. Most people can stay in their home while we build.
Preserve Outdoor Space
Build vertically to maintain your backyard, garden, or pool area— ideal for smaller blocks.
Add Views and Light
Second levels can open up elevated outlooks and bring in more sunlight, enhancing both value and lifestyle.
Get More Privacy
Create spacious master suites or quiet study areas completely separated from the main living zone.
Boost Property Value
Second storey additions are a strong investment, often delivering a higher return by substantially increasing usable floor area.
