Stage 01 · Foundation

Start with what holds.

We pour footings that hold. Bored piers where the ground needs them, slabs where it doesn't. Cured, level, plumb. Everything above stands straight for the life of the house.

Stage 02 · Frame

The bones go up.

The frame is where a house gets its posture. Hardwood, engineered timber, joinery cut tight. You can't see it once the walls are up but you can feel it every time you close a door.

Stage 03 · Walls

The layer between you and Sydney.

Insulation tuned to the climate. Wrap and flashing that take coastal humidity and summer sun. Cladding you're still proud of in twenty years.

Stage 04 · Roof

The crown.

Engineered trusses, sheet metal or tile, flashing done right the first time so you never hear a drip. A roof should last decades, not seasons.

Stage 05 · Finishing

Where it becomes yours.

Windows, doors, fixtures, fittings. The small decisions that make a house feel lived-in before you've moved the first box. We work with you on every one.
