What we do

PAC Studio is an architectural practice where environmental considerations are fundamental to making spaces and places that feel good. Our projects are filled with natural light, the warmth of the sun, and the breath of fresh air. Each project is a unique solution, responding to the particular needs and desires of our clients within the context, culture and climate of both site and use. We seek the critical engagement of our clients in the development of design solutions that are affordable, comfortable, stimulating and efficient to use; this involves our development of a range of both physical and BIM digital models throughout the course of every project to simulate and test the qualities of light, space and materials, set within the context of environmental performance.

Rigorous management through the design process and the construction stages in particular is fundamental to our success in the delivery of projects that exceed expectations, whilst remaining within the budgets and timescales our clients demand. A core element of the practice is the concept of design for life – a recognition that the use of the built environment over time is continuously adapting and evolving. Our long-term involvement with our clients and the users of our designs beyond ‘practical completion’ of the project is key to our design approach. It is in this context that many of our projects originate through recommendations and repeat commissions from our existing clients and the wider design and contracting teams involved in our projects, testament to our core ethos of collaboration and client satisfaction. We work for a range of Clients within both the Private and Public Sectors, including the Office of Public Works, The Health Service Executive, and numerous Local Authorities and Education Institutes.

Our core desire is to provide healthy environments for living, working and relaxing, through an understanding of the inter-relationship of users, spaces, buildings and the wider context of climate and weather. Ongoing research and design work delivers measurable, energy-efficient design solutions, both comfortable in use and pleasurable in experience.

Who we are
