MosArt was established in 1993 by Art McCormack – a highly talented architect and Tomas O’Leary – an innovative environmental designer. Art and Tomas both shared the same convictions; that people should be able to enjoy the highest standard of living, without negatively affecting the natural environment.

With housing currently being responsible for a quarter of all greenhouse gas emissions, Art and Tomas introduced Ireland with a cost effective solution that can all but eliminate the carbon footprint that people are forced to create through living in conventional housing. The solution was to change what is “conventional”, to a more environmentally friendly solution -nZEB and Passive House.

High performance nZEB and Passive House means healthier, happier lives for people today, and for future generations. MosArt now offers some of the world’s most innovative, low carbon design solutions across architecture and urban design, for residential, commercial and public sectors. MosArt also works with government bodies to ensure renewable energy sources, such as wind farms and forestry, do not disrupt the beauty of our native landscape.

For clients who won’t be swayed toward going green, MosArt still offer a more conventional architecture and landscape design service coupled with their clientcentric approach to design and execution, gained from MosArt’s many years of experience.
