COSA Architects is a small practice set up by Principal Conor O’Sullivan in 1997. 

Since it’s inception the practice has focused on client centered design solutions using the knowledge of both construction methodology and design experience gained from extensive practice on a wide variety of buildings both in Ireland and the United Kingdom. 

The practice has been sized to ensure full client contact with Principals in the practice at all stages of the project with small to medium sized projects resourced from within the practice and larger projects resourced with additional facilities available to the practice from previous project teams. 

COSA Architects has a well established track record in the delivery of high quality architecture, and built works have been published in national design magazines and national newspapers. 

The philosophy of the practice from the beginning has been to understand the real needs of the client at the commencement of a commission and to shape the project at each subsequent stage with that understanding, infused with the design and construction expertise built up over 20 years to provide a built solution of quality and integrity which provides the client with the building they initially required - and more.
