"Will has now completed two projects for us. A carport rebuild and a large gazebo. Both have exceeded our expectations. We gave Will a basic concept and he pulled the job together for us. All completed to budget and we even added extras along the way. I highly recommend Will and his team for excellent workmanship and a quality job."

Based in Glenfield -
North Shore, Auckland
Most builders who appear for North Shore searches are based in Takapuna, Birkenhead, or somewhere across the bridge. O'Neill Construction is based at 56 Park Road, Glenfield. When we visit your site for a quote, we know the streets. When your job starts, there's no Glenfield travel time added to the day.
For homeowners getting multiple quotes, a licensed builder Auckland with direct familiarity with local section types, access patterns, and North Shore council processes will scope a job more accurately than one who's working from a distance. We've been doing this in Glenfield and the surrounding suburbs for 11 years.
The Homes We Work
On in Glenfield
Glenfield's residential stock is largely from the 1960s, 1970s, and 1980s. Brick-and-timber homes that are well-built but often due for a serious update - original kitchens and bathrooms that haven't been touched in 30 years, or rear sections with room to extend but no covered outdoor space yet.
A typical Glenfield renovation for us involves opening up a rear living area, replacing a dated kitchen and bathroom in a single job scope, or adding a deck to the back of the house on a section that slopes away from the living level. These jobs suit a builder who can manage the full scope rather than coordinating multiple trades.
The terrain matters here. Glenfield sections are hilly - some steeply so - which affects how decks and extensions connect to the house and what the foundation specification looks like. When we quote in Glenfield, we're not guessing at what we'll find; we know the soil types, the typical access constraints, and the kind of framing that's inside a 1970s North Shore home.
We also cover the surrounding suburbs from the same base - Birkdale, Beach Haven, Northcote, and Birkenhead are all within a few minutes of Glenfield and share the same property profile.
