Expert Witness and Assistance to Legal Firms

McGarry Ní Éanaigh Architects offer legal firms and clients expert services including opinions on professional practice, building defects and contract administration. We are expressly aware of the duties of an expert to the courts to be independent, thorough, unbiased and well researched.


We have been developing our expertise in architectural practice for over 35 years. Although we have particular experience in educational work having designed 20 schools, our body of work also includes housing, residential, office, community leisure buildings and urban design/public spaces.

We have a strong track record of researching innovative design concepts and details in order to realise each unique project – designing from first principles. This thorough, rigorous, interrogative working methodology carries through into our expert services for clients.

Our team has six years of direct service in legal work, which has given us in-depth knowledge of the legal process in a construction setting, from pleadings and hearings to expert reports and discovery.


We can assist legal firms and clients to:
· Understand the custom and practice for architects and other construction professionals.
· Furnish opinions on how a reasonably competent architect would view a particular situation such as a delay to the works, a claimed variation or the operation of clauses in a contract.
· Translate issues from a construction setting into common language and, when requested, into documents for use in a legal setting.
