Interior Design Cost in Singapore (2026)
Quick Answer
Estimated rangeIn Singapore, interior design costs vary widely by home size and how much renovation work is included. A practical market estimate is around SGD 20,000-40,000 for a 3-room HDB flat, SGD 30,000-60,000 for a 4-room flat, and SGD 40,000-80,000+ for a 5-room flat or condominium when design is bundled with fit-out works; design-only consultancy is often priced separately and may be charged hourly or as a percentage of project value.
Overview
In Singapore, interior design is commonly sold as part of a wider renovation package rather than as a standalone decorating service. That means the price a homeowner pays usually covers space planning, mood boards, 3D drawings, project coordination, and the built works themselves such as carpentry, flooring, painting, electrical and plumbing changes. As a result, there is no single regulated market rate, and quotes differ sharply depending on property type, floor area, condition of the unit, extent of hacking or wet works, and whether custom carpentry is required. For budgeting, homeowners in Singapore often see all-in interior design and renovation packages for HDB flats starting from the low tens of thousands of dollars, rising substantially for larger flats, condominiums and landed homes. Design-only services, especially from boutique studios or for higher-end homes, may instead be billed by consultation hour, as a fixed design fee, or as a percentage of project cost. Singapore does not have a single mandatory trade licence specifically for interior designers, but consumers commonly check whether a renovation contractor is listed in the HDB Directory of Renovation Contractors for HDB work. It is also common to compare several itemised quotations, because pricing is highly sensitive to materials, bespoke joinery and the amount of coordination needed.

Local Context
Singapore residential interior design quotes are usually given in Singapore dollars and often include a bundled renovation scope rather than a pure design fee. GST may or may not be shown separately depending on the supplier's billing format, so homeowners should confirm whether the quote is GST-inclusive. Tipping is not customary. HDB projects also need to follow HDB renovation rules, and this can affect timeline, permitted works and contractor choice.
