He has tutored in both design and graphics at architectural faculties in Sydney tertiary institutions, and maintains a keen interest in landscape, and urban and industrial design.
Peter has been involved with the design of aged care facilities, particularly for those suffering from dementia, for over 20 years. His work with the HammondCare Group in the early 1990s set a new standard for dementia care, developing the idea that a building can actively assist with aiding residents' well-being. In 1995, The HammondCare Group published a booklet written by healthcare consultant Theresa Kramer and Peter Ireland entitled "Building Peace of Mind: The Meadows Dementia Hostel." The booklet covered the philosophy of care, dementia design principles and prosthetic and therapeutic environments. The booklet is still providing the ground rules for the design of dementia care today. Peter has applied these principles to many aged care projects including the Bodington aged care facility at Wentworth Falls, HammondCare at Erina and Hammondville, the Inner West Health Centre at Croydon, and the Ryde Rehabilitation Centre, Ryde.
More recently, Peter has worked with Anglican Retirement Villages and Opal Aged Care as well as two new projects for HammondCare at Cardiff and Hammondville.
