Ceardean have helped and been with my business every step of the way. Without them we wouldn't be where we are today. If you want attention to detail, out of the box designs and friendly service they are the crowd to go with. Couldn't recommend them more.

We approached Derek at Ceardean as we often passed his office with his sign outside and liked his style from the website. We initially contracted for a few design ideas and quickly realised he understood well what we wanted and went with him for the whole project. Ceardean were fantastic from start to end. When our planning was declined initially they helped us through the appeal process with an Bord pleanala and after delivering very clear documents the planning was approved. Throughout the project the project management was great at keeping the project on track and on budget. We would definitely recommend

Worked with Ceardean on the design of One Society. No project is without challenges but have to say we worked closely with Ceardean to ensure our vision was reached. They have a solid team behind them.

We chose Ceardean to design and look after the renovations on our new home. It was the best decision we made. Derek came up with a fabulous design which was exactly what we were looking for. He and his team helped us through the whole process from design, planning permission, tenders and project managed the build for us. The result was the perfect home for us. I would highly recommend Ceardean after our experience.
