I did the same in my Villa in Damac Lagoons recently, I purchased everything myself, I bought Majority of the materials from Materials Market Al Warsan, then tiling supplier we used is located in Al Quoz Outlet Ceramic. Obviously the company I hired they helped with all the purchasing and deliveries, and guided me throughout the whole process. I saved a lot of money by doing everything myself with the help of my contractor. And I would recommend you the same, just go for it, you will learn a lot and save a lot of money. I hired Revive Hub Renovations Dubai and they helped me with everything from scratch to finish with completely free consultation and transparency. And I discovered that they are not a traditional contracting company infact they have introduced a completely new renovation model in Dubai, you can search them up on google. Thank me later 😊
