Mallon Building Ltd
Renovation builder · Dunedin & South Otago

Renovations that respect the house you already have.

From changing a layout to a major whole-house alteration, Mallon Building brings practical experience to existing homes—where the work is rarely as simple as drawing a new line on a plan.

Changing an existing home

Renovation building begins with what is already there. Structure, earlier additions, uneven framing and hidden services can all shape the best way forward. Tony's experience across alterations and detailed residential construction helps turn those constraints into clear, workable decisions.

Mallon Building undertakes home renovations and house alterations from Milton to Dunedin, including changes to room layouts, structural alterations, exterior upgrades and projects that combine existing work with new construction.

What an alteration can involve

  • Reworking rooms to create a more useful layout
  • Opening, dividing or connecting living spaces
  • Renovating older houses and previous additions
  • Structural alterations and associated building work
  • Exterior cladding, roofing, window and door work as part of a wider project
  • Coordinating trusted subcontractors through the build

Older homes need considered decisions

Older homes often carry evidence of several generations of building. Walls may not be where the drawings suggest. Materials and levels change. Previous repairs can create new questions. The answer is not to promise that nothing unexpected will happen; it is to have someone capable of assessing what is found and explaining the practical options.

Tony's approach

Mallon Building considers likely possibilities when pricing and uses subcontractors Tony knows and trusts. Clients have described Tony as honest, reliable, communicative and ready to listen while offering useful suggestions.
