We worked with Ivonne of The Alchemists Design to renovate our 4-room BTO. She is very friendly and prompt in replying our queries. Alchemists also dispatches its teams (plumbing, carpentry, electricity, etc.) very quickly, sometimes even within hours after we give feedback. The defects rectification was quite quick as well. The quality of the work was largely good too. Overall we had a good experience working with Ivonne and Alchemists.
