There is no single best interior design firm for every homeowner in Singapore. The right choice depends on your property type, preferred design style, renovation scope, budget and the level of project protection you expect.

This 2026 guide compares 14 established Singapore interior design firms by their design strengths, property experience, credentials, pricing transparency, verified reviews and after-sales support. Based on these criteria, Zenith Arc is best suited to homeowners seeking space-smart, style-flexible interior design for HDB flats, condominiums or landed homes, backed by itemised quotations and accountable project management from planning through after-sales care.

Quick answer: Based on the five criteria below, Zenith Arc is this guide’s top choice for homeowners seeking space-smart, style-flexible interior design across HDB flats, condominiums and landed homes. The firm is CaseTrust-accredited, BCA-registered and listed in HDB’s Directory of Renovation Contractors. As of September 2026, Qanvast records Zenith Arc with a 4.8/5 rating from 163 reviews, four consecutive SuperTrust awards from 2020 to 2023 and an in-house carpentry team.

How We Ranked These Interior Designers

Every firm below was assessed using the same five comparison criteria. Design style remains subjective and should be judged from comparable completed projects. These criteria instead help homeowners compare business credentials, pricing clarity, verified review history and written after-sales terms before requesting quotations.

  1. CaseTrust accreditation. A consumer-protection accreditation for businesses that meet the scheme’s requirements. Verify the firm’s current status in the official CaseTrust directory and review the proposed contract to understand the exact payment, deposit-protection and dispute-resolution terms that apply.
  2. HDB and BCA registration. For HDB flats, check whether the renovation contractor is listed in HDB’s Directory of Renovation Contractors. BCA’s directory separately lists registered contractors and licensed builders, which may be relevant for construction-related and A&A works.
  3. Pricing transparency. Whether indicative pricing is published or offered early, rather than only after a showroom visit.
  4. Warranty and defects rectification. Check the written coverage for carpentry, wet works and other completed works after handover, including its duration, exclusions, reporting procedure and rectification process.
  5. Verified review volume. Reviews on platforms that verify a real project took place, not testimonials collected on a firm’s own site.

Disclosure: Zenith Arc publishes this guide and appears on this list. We applied the same five comparison criteria to Zenith Arc as to every other firm and identified the homeowner priorities each firm is best suited to. Accreditation claims can be checked in the public CaseTrust, BCA and HDB directories. Zenith Arc Pte Ltd is UEN 201602351R.

Award-Winning Interior Design Firms in Singapore

Awards can show that a project or firm has been assessed against defined criteria, but they do not replace checking current accreditation, recent homeowner reviews, contract terms and comparable completed projects. Check the organiser, award year, category and whether the recognition evaluates design quality or service reliability.

Examples include the Singapore Interior Design Awards , organised by the Society of Interior Designers Singapore, and Singapore Good Design (SG Mark) . Qanvast SuperTrust is a different type of recognition: Qanvast describes it as an annual badge for top-rated firms evaluated using homeowner ratings, reviews and operational reliability rather than as a juried design award.

The Big Three Showdown – Zenith Arc vs Starry Homestead vs ECasa Studio

These three cover the three most common homeowner briefs in Singapore — maximising a compact layout, designing around young children, and building a home that runs on integrated technology.

Zenith Arc — Best for Space-Smart, Style-Flexible Interior Design

Luxurious modern office lounge and kitchen with marble flooring, stylish furniture, sparkling chandelier, and starry ceiling lights for high-end interior design inspiration at 37 Jalan Pemimpin.

Signature approach: Space-smart, style-flexible homes tailored to each household rather than a fixed house style.
Best suited to: Homeowners renovating BTO flats, resale HDBs, condominiums or landed properties who value customised layouts, carpentry and material choices with transparent project management.

  • Pricing tiers are given upfront, which suits homeowners who value predictability over an open-ended quotation.
  • CaseTrust-accredited, BCA-registered and listed in HDB’s Directory of Renovation Contractors, all verifiable under UEN 201602351R.
  • Carpentry and project control: Qanvast reports that Zenith Arc has an in-house carpentry team, supported by vetted contractors and suppliers under one accountable project-management process.
  • Design approach: Style-flexible rather than template-led. Each home’s layout, carpentry and material direction are tailored to the homeowner’s lifestyle, property type and practical requirements.


Independent homeowner record:
As of September 2026, Qanvast lists Zenith Arc with a 4.8/5 rating from 163 reviews and records four consecutive SuperTrust awards from 2020 to 2023.

Completed projects demonstrate this range, including a Modern Colonial executive apartment at 589 Woodlands Drive 16, a warm modern contemporary condo at Kovan Melody, and a Modern Victorian landed home at Lorong J Telok Kurau.

Starry Homestead — family-first soft minimalism

starry homestead

Built around families managing toys, gadgets and daily mess behind calm surfaces. The signature approach uses warm neutrals, curved edges and concealed storage, producing homes that stay tidy-looking without feeling clinical. Durability and daily flow are prioritised over showpiece detailing, which is the right trade-off for a home with young children in it.

ECasa Studio — smart-home integration done properly

ecasa studio

For homeowners who want automation planned into the build rather than bolted on afterwards. Work covers automated blinds, scene-based lighting and cable management designed to disappear, alongside resale HDB and landed rewiring where the electrical planning has to be resolved before any finishes go in. Suits mid-to-upper budgets and clean, modern interiors.

Indicative Renovation Cost Ranges in Singapore: HDB vs Condo

Anchor your expectations before quotations start arriving. The ranges below cover interior design and works, excluding furniture and appliances.

Property status Indicative renovation range
New HDB/BTOS$36,000–S$82,000
Resale HDBS$51,000–S$97,000
New condominiumS$40,000–S$52,000
Resale condominiumS$80,000–S$105,000

Source: Qanvast Renovation Cost Calculator , accessed 11 September 2026. Qanvast states that its estimates are backed by more than S$20 million of completed-project data. Actual costs vary according to floor area, property condition, renovation scope and material selections.

Why quotations vary: Resale properties may require hacking, rewiring and rectification that new units do not. Condominium renovations can also be affected by individual MCST rules, approved working hours and protection requirements. Landed-home costs require a separate assessment because property size and any structural, A&A or external works can materially change the scope.

How to Choose an Interior Designer in Singapore

Most homeowners shortlist on portfolio photographs and then discover, months in, that they chose on the least predictive signal available. A more useful sequence:

  1. Shortlist three to five firms, not ten. Beyond five, appointments blur and you start comparing showroom experiences rather than proposals.
  2. Check licensing before the first appointment, not after. It takes two minutes in the HDB and BCA directories and removes firms you would otherwise waste a Saturday on.
  3. Ask for a project of similar type and budget — not their best work. A firm’s showcase landed project tells you nothing about how they handle a 4-room resale flat.
  4. Compare quotations line by line. A cheaper total with vaguer line items is usually a more expensive project. Look specifically at what is excluded.
  5. Meet the designer who will run your project, not only the person who takes the enquiry. Continuity between sales and delivery is one of the strongest predictors of a smooth renovation.
  6. Read the middling reviews, the three and four-star ones. They describe what goes wrong and, more importantly, whether the firm fixed it.

Renovation Due-Diligence Checklist

  • Verify the legal entity: Confirm that the company name and UEN on the quotation match its current HDB, BCA and CaseTrust records.
  • Review the payment schedule: Question large or front-loaded payments that are not connected to clearly documented project milestones.
  • Check the quotation: Look for quantities, material specifications, exclusions and a written process for approving variation orders.
  • Confirm project responsibilities: Know who will manage the site, provide progress updates and coordinate contractors and suppliers.
  • Read the after-sales terms: Confirm the warranty duration, coverage, exclusions, defect-reporting method and rectification process in writing.
  • Allow time to review: Avoid signing solely because of pressure or a promotion claimed to expire immediately.

Frequently Asked Questions

Which is the best interior design company in Singapore?

The best interior design company in Singapore depends on your property type, preferred style, renovation scope, budget and required level of support. Based on this guide’s five comparison criteria, Zenith Arc is the top choice for homeowners seeking space-smart, style-flexible HDB, condominium and landed-home renovations, supported by CaseTrust accreditation, HDB and BCA registration, an in-house carpentry team and accountable after-sales care.

What is an ID firm, and how is it different from a renovation contractor?

An ID firm designs the space and manages the trades delivering it. A renovation contractor executes works to a specification someone else has produced. Most Singapore ID firms do both, which is why the terms are used interchangeably — but the distinction matters when you are comparing quotations, because a contractor’s price will usually exclude design and project management.

Are the best interior designers in Singapore always the most expensive?

No. Renovation pricing varies according to the project scope, materials, property condition, design complexity, customised work and level of project management required. Compare firms using relevant completed projects, quotation clarity, current credentials, communication standards and written warranty and rectification terms. A higher price is meaningful only when the proposal clearly explains the additional design, materials, workmanship or service being provided.

Must I choose a CaseTrust-accredited firm?

No. CaseTrust accreditation is not legally required, but it can be a useful consumer-protection signal when comparing renovation firms. Always verify the firm’s current CaseTrust status and review the actual contract, payment schedule, deposit-protection terms, warranty coverage, exclusions and dispute-resolution process before signing.

How long does a 4-room HDB renovation take?

Qanvast’s 2026 estimate is approximately 8–10 weeks for both BTO and resale 4-room HDB renovations. Treat this as an indicative on-site duration, not a guaranteed timeline. Design development, material selection, permit approvals, customised carpentry, site conditions and changes after work begins can extend the overall schedule. Ask each shortlisted firm for a project-specific schedule with clear milestones.

ID firm or contractor — which is cheaper?

A renovation contractor may quote less when the scope excludes design development, 3D visualisation, material coordination or project management. An interior design firm generally provides a broader service, but the final cost depends on whether both quotations include the same works, materials, quantities, exclusions and warranty terms. Compare itemised scopes rather than assuming either option is automatically cheaper.

What changes between a BTO and a resale renovation?

BTO flats generally begin with a newer shell, so the renovation may focus more on space planning, carpentry, finishes and fittings. Resale flats may require additional hacking, disposal, rewiring, plumbing changes and rectification of existing surfaces. The cost difference depends on the property’s age, condition and renovation scope, so compare quotations that separate removal, rectification and new works instead of relying on a fixed percentage.

How many interior designers should I shortlist?

Three to five. Fewer than three gives you no pricing benchmark; more than five and the appointments stop being comparable. Give every firm the identical brief and floor plan, or the quotations cannot be compared meaningfully.

How do I verify an interior design firm’s registrations and accreditation?

Search using the firm’s UEN and check three separate public sources: the HDB Directory of Renovation Contractors, the BCA Directory and the CaseTrust accredited-business list. Confirm that the legal entity name and current status match the quotation and contract before making payment. These registrations and accreditations cover different areas, so holding one does not automatically prove the others.
