Who we are & What we do

Ceardean is a close unit of experienced architects, designers and specialist consultants with a shared ethos of skilled making and design collaboration based in Dublin 8. Our approach is to work as artisans blending and focusing disciplines to create elegant, functional and cost effective designs for our clients. We strive to understand the given environmental context and react by designing settings that enhance, protect and take advantage of natures forces.

Our process creates sustainable buildings that are flexible in use and sensitive in nature.
