Jun Wei had just collected his EC keys at a Sengkang development in 2022. He’d planned to start renovating immediately. His preferred contractor’s next available slot: 16 weeks out. That’s when he realised you don’t find a renovator after you get your keys — you find one before.

Why Renovation Planning Starts Before TOP

When a large EC development (560 units like Tengah Garden Walk EC) completes TOP, hundreds of owners simultaneously need renovation. Quality interior design firms and renovation contractors book out 3–6 months in advance during peak EC TOP seasons.

With TOP expected around 2029, smart buyers will start shortlisting contractors 12 months before TOP. By the time you collect keys, your renovation should be scheduled and ready to start.

Room-by-Room Budget Guide: 3-Bedroom EC (90sqm)

Total Budget Ranges by Tier

• Basic (functional, no-frills): $60,000–$80,000
• Mid-range (quality materials, full ID): $90,000–$130,000
• Premium (luxury finishes, full ID concept): $140,000–$200,000+

Should You Hire an Interior Designer?

Interior designers typically charge 10–15% of renovation cost as their fee. For a $100,000 renovation, that’s $10,000–$15,000. What you get: a cohesive design concept, project coordination, permit management, and often access to better trade pricing on materials.

For buyers who want a polished, coordinated home without managing contractors directly: worth the premium. For buyers comfortable managing renovation themselves: go with a contractor directly.
