  • About The Project

    Gaden House is a seminal building designed by Sydney Architect; Neville Gruzman who was prominent in the 1960s, 1970s & 1980s. The objective for the project was to add an additional two floors above the existing three storey building without interfering with the integrity of Gruzman’s design.  Initially, the building was not heritage listed, but when the DA was lodged, council decided to place an IHO (interim heritage order) on the building. Under Heritage 21’s advice to the client, it was recommended that heritage listing should not be opposed. However, council decided not only to list the building at a local level, but also at State level. This was opposed because, in Heritage 21’s opinion, Gruzman was only active at a local level. A petition to the State Government was made against the State listing and this was successful.

  • What was done

    A Conservation Management Plan was written for the building. It analysed all the key aspects of Gruzman’s design and provided long term conservation policies for the ongoing repairs and maintenance required. Thus, in the new design, all of the key significant elements were protected. In this manner, the rationalisation of services and required exits were introduced in order to make the building safe and functional without losing any of the heritage – significant elements. This culminated in a DA being lodged, which ultimately was refused by council.

Services provided

  • Detailed heritage advice regarding significance of fabric and the integration of the additional floors into the existing building without degrading Gruzman’s fine design.
Why was the work undertaken?

There were several reasons for the project to commence. Firstly, the building fabric had fallen into serious disrepair. Mainly, the sun-controlled louvers which are a key element of Gruzman’s design were in an advanced state of dilapidation. Secondly, the building was unsafe in terms of its required fire egress, noncompliance stair balustrades heights and serious structural issues. Additionally, to make all of these repairs economically viable, additional floors were necessary.

Who was the work completed for?

AMA Holdings


Unfortunately, due to the long and protracted dealings with council and the State Government as well as the refusal for the additional two floors by council, the client withdrew from the project and sold the building.

I have worked with Heritage 21 over numerous projects across Sydney and have found them to be valuable project partners in the development process. ”
