From first sketch to front-door keys
Every extension and renovation we build follows the same eight clear stages — so you always know what's happening, who's responsible, and what comes next. No surprises, just a considered path to your finished home.

How the Bayside Extensions process works
Our process moves through eight stages: 1) design consultation, 2) concept design, 3) documentation, 4) the HIA contract, 5) building permit, 6) construction, 7) completion and handover, and 8) aftercare. We handle design, permits, insurances and the build in-house, and back the finished work with a 10-year structural warranty and up to 15 months of maintenance cover.
Our 8-step design & build procedure
The same considered path, whether you're adding a ground-floor room, a second storey or renovating throughout.
Let's unlock your home's potential
A designer from our architecture and design team reaches out to brainstorm ideas, learn about your home improvement goals, and understand how we can help build your ideal home.

Let's lay the foundations. Once the design and cost are agreed, we present a preliminary agreement covering the preparatory works — soil testing, engineering, working drawings, town planning and interior design where applicable.
