Landed Interior Design in Singapore: Buying Guide →Key takeaways
- Start with the proposed work rather than a company’s marketing title.
- Building and planning clearance questions need the appropriate professional advice.
- Name who coordinates the work and what their appointment actually includes.
A job title is not a complete appointment
An interior designer may help with layout, finishes, lighting and furniture; a contractor may organise and execute construction. An architect or engineer may be needed for professional design and clearance responsibilities depending on the works. Some firms offer several roles, but the scope and named responsibility should still be explicit.
BCA advises private property owners to engage a Qualified Person for advice on required clearances. Its guidance identifies QPs as registered architects or professional engineers with a valid practising certificate. Do not infer that a person is acting as the project’s QP merely because a design firm says it has professional contacts.

Map the work to a responsible role
| Work or decision | Clarify the appointment |
|---|---|
| Room planning, finishes and furniture | Who develops the design and documents the approved selections? |
| Changes affecting building fabric or structure | Who investigates feasibility and provides the required professional advice? |
| Planning and other authority clearances | Who identifies the requirements, prepares submissions where needed and tracks them? |
| Construction and specialist installations | Who executes the work and coordinates subcontractors? |
| Cost and variation review | Who checks the proposed change against the agreed scope? |
| Site review and defects | Who attends, what do they review and how are issues closed? |
Do not use “interior works” as an approval conclusion
URA states that planning requirements depend on the property and nature of the works. BCA separately notes that exemption from its plan-submission process does not remove other relevant authority requirements. A proposal called an interior makeover can still contain items that need professional review.
List the actual changes, including proposed wall removal, floor openings, extensions or changes to services. Have the appropriate professionals assess them before the design is treated as feasible. This article does not decide the approval route for a particular house.

Compare deliverables and boundaries
Ask whether the design fee includes measured drawings, detailed carpentry drawings, lighting and electrical coordination, material schedules, tender comparison and site attendance. “Project management included” should state who attends, how often or at which stages, and what decisions they are authorised to make.
Clarify what is excluded and who appoints the missing role. An owner who separately hires a designer, builder and specialist suppliers needs an agreed coordinator. Otherwise each business may reasonably assume another is resolving the interface.
Where a registered architect is proposed, verify the person and firm through the Board of Architects’ available registers and confirm the actual appointment. Registration information is one check; it does not by itself explain the services purchased.
Use the contract to make the team understandable
Ask for clear work, payment and change schedules. CaseTrust’s renovation accreditation framework illustrates these practices for accredited businesses. Check current accreditation and applicable terms where a firm relies on that status; do not assume the logo replaces reading the agreement.
The right team is the one whose roles cover the actual scope without unexplained gaps. A small furnishing project and a substantial landed-house alteration should not be compared as if they need the same appointments.
