We had the pleasure of creating a beautiful outdoor space for our clients, inclusive of a substantial kwila deck and benches for seating. The deck was designed to maximise our clients section space and to tie in with their existing outdoor spaces.

Home renovation project for an old villa

Residential Dwelling (Villa Renovation) - Beckenham

A run down old villa with beautiful bones, was completely renovated. The end result was a home that retained the charm of its heritage features, however with a modern use of space and colour and high quality finishes. Work included a new kitchen, new bathroom, re-configured rooms, new deck and complete interior and exterior refurbishment.


Residential Dwelling (Villa Renovation) - Beckenham

We have recently completed an extension designed by Peter Dunbar Architects. They are extremely happy with the end result, and have commented on our quality, speed, hard work and accurate construction programming. The photo below illustrates the extension joining the existing house

As this was the first time we have done a major renovation, we didn't know quite what to expect.  Galletly Builders were fantastic to work with.  Their communication was exemplary, seeking our opinions as needed, but also providing advice and updates regularly.  Everything was completed on time and to a high standard.  If we require a builder in future we would go Galletly Builders again.

Residential Dwelling (House Extension) - Cashmere

We completed all tasks related to completing extensions to the 2nd and 3rd levels of this lovely home in Bowenvale Valley. The existing home already had high quality finishes, hence it was critical we complete the extensions to the same standard, and that they were a seamless addition to the existing house. We increased the living space and introduced an additional bedroom, as well as constructing new decking and an outdoor living space.
