How Much Does an Interior Designer Cost in Singapore?
- There are three common structures.
- Each has trade-offs.
- Scope moves the number more than the designer's rate does.
We do not quote prices here, because fees vary too much between firms and projects for a single figure to help. What helps is knowing how fees are structured, since that explains most of the gap between quotes.
There are three common structures. A flat design fee covers design only, with construction contracted separately, often by the homeowner. A percentage of the renovation cost is common among full-service studios. A design-and-build package quotes design and construction as one number with no separate design line.
Each has trade-offs. A flat fee gives you the most control over contractors and materials, but you manage the contractors yourself. A percentage fee rises with the renovation cost, so ask how the firm avoids padding scope. A design-and-build price is simpler to budget around but harder to compare, because you cannot see how much covers design, labour and materials markup.
Scope moves the number more than the designer's rate does. A firm quoting full custom carpentry, bespoke furniture and hands-on project management will cost more than one giving design direction for you to execute. Comparing those two quotes is comparing different jobs.
Material grade matters too. A kitchen with laminate cabinetry and standard fittings costs far less than the same layout in solid timber joinery with imported hardware, though both may read kitchen renovation on the cover page. Ask what grade each quote assumes.
Some costs sit outside the headline fee: HDB or MCST permit fees, temporary storage while work is under way and a contingency of around ten to fifteen percent. Confirm whether GST is included, since a quote without it can look cheaper than one with it. Ask what triggered variation orders on past projects and how they were priced.
Payments usually follow milestones such as design confirmation, start of hacking, completion of carpentry and handover, and that ties money to progress. Some banks also offer renovation loans, which are worth comparing with paying from savings. Get every quote in writing and itemised. When an invoice arrives, ask what the number is for.
