← Construction Extensions & Additions

More room to live,
without leaving home.

Ground-floor extensions and additions that add living space, bedrooms, bigger kitchens and indoor-outdoor living, integrated properly with the home you already have.

Space that
actually works.

01

Designed Around You

More space is only worth it if it works. We focus on flow, light and how the new rooms connect to the rest of the home.

02

Integrated, Not Bolted-On

New footings, framing, roof and envelope, detailed so the addition feels part of the home rather than tacked to the side.

03

Resolved Before We Build

Excavation, structure and budget are worked through in the PAC Process, so the extension is priced and planned before site starts.

Room to
grow into.

Extensions to increase living space, add bedrooms, expand kitchens or open the home up to new indoor-outdoor living areas.

Delivered as staged site works: demolition, excavation and footings, framing or structural construction, roof and external envelope, services, finishes and final integration with the existing dwelling.

Indicative investment: typically $300,000 to $1,500,000+, depending on footprint, excavation, structure, roofing, services, glazing and finishes. A guide only, confirmed in a project-specific proposal.

Staged,
and sequenced.

An addition touches the existing home at every stage, so we plan the sequence carefully to keep it weather-tight and liveable throughout.
