Which Interior Designers do you recommend that is reasonable in price and value for money?

You should join this Facebook group - Budget Reno (Singapore)! The members are really passionate about the home reno topic and will be able to recommend you a good ID based on their experience :)

Otherwise, you can start with browsing HomeRenoGuru for some ID recommendations and inspiration. All the best!

There so so many ID out there in Singapore. Very hard to answer your this type of question. I suggest you meet up with a few ID, determine what style of renovations do you want and work it out the ID. Have a budget in mind that you can afford and work towards to.
