Classmates were great. Most importantly, Phil & Brent incredibly kind, patient and easy going. Nothing was ever a problem. If you think to do this course, don’t hesitate. Two days of relaxed creative fun. You also walk away with a vanity benchtop and a table top.

The course was excellent.

Very informative and hands on makes it easy to learn the skills.

Jack Horton
It was absolutely brilliant from beginning to end!

I just took part in a recent concrete casting workshop with Phil and Brett. Phil is so generous with his knowledge, friendly and accommodating. We made a stunning vanity sink and table top. Well worth the course fee and I could not recommend this experience more highly 10/10

Monique Tippett
Incredible amount of skills and knowledge...

...shared in a practical and digestible way in such a short timeframe. Great people, great lunch, great value

Andrew Britton
Phil and the Team at Concrete Studio delivered an excellent, hands on 2-day course.

Good insight into GFRC and how it could be used and being able to make a vanity top and bench top was very satisfying. Appreciated Phil's openness with sharing his knowledge. 10/10 for the lunches provided, thanks thanks to ilka.
