She obtained a Bachelor of Arts Honours degree B.A. (Hons) from the University of Kingston-Upon-Thames in England, a Bachelor of Architecture B.Arch (Hons) from the University of Newcastle-Upon-Tyne in England, completed her professional studies in University College Dublin and was elected a Member of the Royal Institute of the Architects of Ireland (MRIAI) in 2001.
She has also been registered in the Register for Architects under the Building Control Act 2007 and may legally use the title Architect and she is an Architect Accredited in Conservation Grade III and a Member of Integrated Project Management (IPM).
She spent a year working in San Francisco, specialising in housing design, construction and interiors and she was a founding member of the Bay Area Young Architects (BAYA). She spent a further year working on the detailing and construction of the 5 Star Hotel Arts, working on site in the Olympic Village of Barcelona, after the Olympics but before the Olympic Village area was completed. In Dublin, Una worked for BDP, extensively on the Connolly Station refurbishment project, the competition-winning offices for Fingal Co. Council along with Bucholz McEvoy Architects, the extension to Marks & Spencer Mary Street, the refurbishment of AIB Bank Terenure amongst many other prestigious projects. Prior to starting her own practice, Una worked exclusively with Anthony Cotter Architects on the new-build of the large Air-Rights Office Building over Connolly Station, including the fit-out of the offices for McKeever Rowan Solicitors and Susquehanna Ireland Ltd.; the entire second floor of the building.
McQuillan Architects was set up as a Ltd. Co. in 2001 to meld the disciplines of art and business, whilst creating beautiful environments for people. In the intervening years, Una has undertaken many prestigious retail, fit-out and refurbishment projects, including many historical buildings; The Law Society of Ireland being one of the most notable.
Since then, Una’s expertise has made her a natural commentator and media presenter. To date she has worked on the series ‘About the House’, for Ireland’s national television station, RTE 1, where she was the co-presenter. Una also regularly appears in the Irish press as an expert on interiors, architecture and the industry.
