About Us

Cornerstone was formed in 1998 by Andrew Harper and Liz Pidgeon to take advantage of the changing property market dynamics in Brisbane.

It is the combination of over 70 years of experience of the Directors that enables Cornerstone to provide a range of services and products to its clients.

Andrew Harper has over 35 years experience in property across all the major market sectors having worked in agency and development during his career. Andrew began his career in 1980 selling houses and then commercial properties in 1983, specialising in commercial office leasing and major investment sales. After gaining his real estate licence in 1987, Andrew took a position with a listed property development company in Sydney working on major office projects. In 1992 he returned to Brisbane to set up his own company specialising in property development and consulting. This enterprise evolved into his present venture, Cornerstone Properties.

Liz Pidgeon has been involved in the property industry for over 30 years. Her experience includes property management, leasing and development gained through working with a major Brisbane agency, her family company and Cornerstone Properties. Liz is a former President of the Property Council of Australia (Queensland Division) and is also a Director of F.A. Pidgeon & Son Pty Ltd.

Outside of the property realm, both Andrew and Liz actively contribute to various groups within the community.

Andrew has assisted the Brisbane Grammar School with the development of their $25M Integrated Learning Centre, as well as the Brisbane City Hall Restoration. Andrew is also a Director of the Museum of Brisbane.

Liz Pidgeon is a past Director of Brisbane Marketing and a former Board Member of the Wesley Research Institute and Property Industry Foundation.
