Working with w interior concepts has been a truly rewarding experience. I started off with a slightly confused brief and with her innovation and eye for detail she really helped me create my vision to be better than I could have even imagined it. Not only has she helped my create a hair salon,it is more then that. She has created a space that myself, staff and clientele love to be in and feel relaxed. We have the perfect balance of natural materials but still modern chic. I could go on……! I highly recommend her skills to everyone and anyone as she is an assett to any design project. If you need inspiration, someone to keep your ideas on the straight and narrow she is your lady I’m already trying to think of more things we could get her to work on in the future.
