Good morning Ailish,
Thank you for your query!
The fireplace is by FOCUS, and is called 'BathyscaFocus' suspended, rotating fireplace; http://www.focus-fireplaces.com/bathyscafocus.
This one was delivered by Glorneys Chimneys & Fireplaces, Kimmage, in Dublin, and although many other lovely designs are available, this is one of our favorites!
Many kind regars
