The studios are located upstairs overlooking the harbour. All studios have natural daylight, high ceilings, storage space, and 24hour access.

The Studios currently house seven locally based artists each working on a year long project of personal works. As well as these artists there is a continuing programme accommodating international visiting artists to spend time working in Westport at Custom House Studios. This is a most interesting aspect of the programme as it allows an opportunity for artists to develop works based on their experiences in Westport and its surrounds. Under this initiative artists have visited from many countries, including Japan, USA, Canada, England, Holland, Czech Republic, Germany, Austria as well as from Ireland. Studios are available at a rent of €25 per week which includes utilities, and can be occupied initially for up to 1 year, with an option to renew for a second and a third year. One studio is set aside for short term stays for visiting artists. There is no living accommodation included in the studios, artists must arrange this for themselves.
