Adding on without it looking bolted on


A bad extension looks tacked on. A good one reads as part of the original house, with the same proportions, the same character, just more of it. On older and character homes that takes a builder who understands how the existing structure works before adding to it.


Out the back, out to the side, or up a level by raising the house and building in underneath. We work out what the block and the council will allow, then design and build it. And because we do the structural work too, the join between old and new is solid, not a weak point.

Character homes are our speciality, so we know how to extend one without losing what makes it worth extending.

  • Designed to suit the existing home, with proportions and character matched, not ignored

  • Raise and build under to gain a whole level without changing the footprint

  • Council & character overlay navigated, handled as part of the job

  • QBCC licensed, structural work and the build, by one team


What we take on

  • Ground-floor extensions, out the back or to the side

  • Raise the house and build in underneath

  • Second-storey additions

  • Tie the new structure into the old, properly

  • Navigate council and the character overlay

  • Design through to a finished, matched result

✓

Every structural job we do carries a 6 year 6 month structural warranty.
