My renovation was completed in 1 month and 1 week. I didn't do any tiling/wall hacking so most of the work is actually in carpentry on the living cabinet/tv console, 3 bedroom wardrobe, study room partition, and master bedroom headboard. Also have the additional aircon works, painting, plumbing, and electrical works as well. The quoted price is cheaper than the one I get from L*vsp**e and St***y Ho**s***d. The latter one told me that my reno might take 2-3 months but the ID that I engaged estimated it will take roughly around 1-1.5 months and he managed to complete the reno ahead of schedule
Overall, I'm quite satisfied with my ID's work since the carpentry result is top-notch. The carpentry fabrication only took roughly around 2 weeks. One thing to take note of is that he might be a bit slow to reply to messages since he is also working on many different reno projects, so you can't expect an immediate response from him every time.
Just PM me if you're interested and I can share his contact
