Common questions

Asked before
every renovation.

The questions we get most, answered without the hedging. If yours isn't here, ask us directly — we'd rather tell you something inconvenient early than let you find it out on site.

  • It depends on the size of your home, the condition it's in, and how much you're changing. Carpentry, hacking and wet works move the number most. Rather than quote a misleading average, we'll give you an itemised quotation after seeing your floor plan — so every dollar is attached to something specific.

  • A contractor builds what they're given. An interior designer works out what should be built in the first place — the layout, the storage, how the light and circulation work — then coordinates the trades who build it. If you already have complete drawings, a contractor may be all you need. If you're still deciding how the space should work, design comes first.

  • Yes — HDB flats and new BTOs are a core part of our work, from 2-room Flexi and 3-room units through 4-room and 5-room flats to Executive Apartments and Maisonettes, alongside condominiums, landed homes and commercial spaces. New BTOs and older resale flats need quite different approaches, and we have a page for each.

  • Yes. We prepare and submit the required HDB permits for works that need them, and we design within HDB's renovation guidelines from the start, so approvals don't derail your timeline.

  • Earlier than most people expect. For a BTO, talking to a designer before key collection means your layout and budget are settled by the time you can start work, rather than losing weeks afterwards. For a resale flat, once the option is exercised is a sensible point. There's no cost to an early conversation.

  • As a general guide: a full BTO renovation typically runs 8 to 14 weeks once works begin, and a resale flat 10 to 16 weeks because the existing finishes have to come out first. Landed homes and anything involving structural work take longer. Light or partial works can be a few weeks. Your quotation comes with a works schedule, so you'll see the expected sequence before anything starts.

  • Yes. Once space planning is settled, we develop 3D visuals of your actual rooms so you can see the design — materials, colours, proportions — before committing to it.

  • No. Coordinating the trades and checking the work is our job, and we keep you updated as things progress. You're welcome on site whenever you like, and there are a few points — such as confirming finishes and the handover walkthrough — where we'll want you there.

  • Absolutely. Kitchens, bathrooms, a single bedroom, built-in storage — partial renovations are common and often the sensible choice. We'll design the new work so it sits naturally with the rest of your home.
