Second storeys, rear additions, granny flats. Stitched seamlessly into the original structure.

Overview

Extensions are the hardest builds to get right. The new work has to feel like it always belonged. We obsess over rooflines, brick coursing, floor levels and trim profiles so the join disappears.

What's included

Every extensions project covers.

  • Second-storey additions
  • Rear and side extensions
  • Granny flats and studios
  • Deck and outdoor living areas
  • Structural engineering coordinated
  • Minimal disruption to existing home
