North Facing.

The name JJ Building Co. has become synonymous with Sydney’s Northern Beaches and surrounding northern suburbs.

Our Projects define some of Australia’s most iconic coastal landmarks. We are highly conscious of the impact construction can have on landscape – and consider it our challenge to honour the history and shape the future of this extremely unique and sacred area.

We would like to acknowledge Country and pay respect to the traditional custodians, the Gayamaygal and Garigal people and their Country on which we gather today.

By building structures that not only satisfy our clients needs but also remain respectful of – and complimentary to – the enhancement of native surrounds, whilst remaining focused on maintaining minimal impact to both local flora and fauna.
