I'm currently using them! I can't speak for the whole company, but the ID I engaged has so far been reliable and responsible so if you want a specific recommendation, you can PM me for the ID's name. I'm in the midst of renovation already and so far, everything has been fine. The initial quote given to us was over our budget but because we felt that the other companies we've been to just didn't feel right, we managed to negotiate to our ideal budget. Of course we had to compromise on some stuff as well but we have no complains (as of now). I think that if you really have a good feeling about your ID and the design, you can always try to negotiate! We belong to the group that's more laidback and clueless...we had absolutely no idea about reno details/procedure and pricing but our ID was patient and explained everything right down to the smallest details for us. I know this might sound dodgy cause this is my first post but I just have always been lurking. Also, initially I had qualms about hiring them too because there didn't seem to be much reviews on their company. So this is just me trying to offer a 'review' to other homeowners out there who might be considering Atelier.
