DTA Chartered Architects was formed in March 1985 by its Principal, Donal Toner. During this time the Practice has established a reputation for having extensive depth of experience and ability within a variety of sectors.

This experience is reflected in the diverse range of projects carried out by members of the Practice. Through a network of contacts and partnership ventures, DTA Chartered Architects can provide services covering the full range of development activity from site identification to site supervision in a manner that is both cost effective and gives clear value for money. In particular, the Practice has extensive experience in the procurement of both Traditional and Design and Build Developments for Housing Associations, Food Sector Design, Sports & Leisure activities, Private Residential Development, as well as the full range of general architectural activity.
