Home extensions · Dunedin & South Otago

More space, without losing what already works.

An extension is new construction joined to an existing building. The junction between the two is where sound planning and renovation experience matter most.

Adding space to an existing home

Families change, priorities shift and a home that once worked can begin to feel tight. An extension can add the room you need while allowing you to remain in the place you know.

Mallon Building has experience with additions and restructuring existing dwellings. That combined perspective is important: the new space must be built well, but it must also connect logically and physically with the existing house.

The connection is the project

Levels, rooflines, cladding, structure and room flow all meet at the boundary between old and new. A good extension does more than add floor area. It improves how the home works as a whole.

Extension and renovation together

Many extension projects involve alterations inside the existing footprint as well. A wall may move, circulation may change, or an old room may take on a different use once the new area opens. Mallon Building can consider the extension and renovation work as one connected project.
