What Our Clients Say

  • "Leigh and his crew demolished my old merbau deck, rebuilt the frame, and installed new spotted gum decking. The boys did a fantastic job, and the area has been completely transformed — we can now properly enjoy the pool and entertaining space."

    Daniel - South Yarra

  • "Our new deck is so well designed. It gave us the outdoor space we needed without breaking our budget. We can’t imagine how we lived without it for so long."

    Thomas - Glen Waverley

  • "Fantastic job on our decking seat. Well built, great attention to detail, and finished exactly as we’d hoped. Would definitely use again."

    Maria - Donvale
