Timelines vary by property type. A BTO renovation typically takes 8–12 weeks from design sign-off. An HDB resale with hacking works runs 10–14 weeks. A full landed renovation can range from 4 to 12 months depending on structural scope. Our 72-Hour Design Sprint surfaces your timeline clearly before you commit.

Yes. We manage all HDB renovation permit applications, including works that require prior approval — hacking of walls, wet works, electrical load increases, and more. You don’t need to deal with the paperwork.

For landed and larger condo projects, we can phase the works to keep part of your home liveable throughout. For BTO and HDB flats, we generally recommend a full vacant renovation for speed and quality — but we’ll advise based on your specific situation.

Most interior designers hand off to a contractor once drawings are done — creating gaps in accountability when site conditions don’t match the design. As a design-build firm, Interea owns both the design and the build under one contract. If something needs to change on site, we resolve it — you don’t get caught in the middle paying for both parties’ time.
