BCA reported preliminary total construction demand of S$50.5 billion in Singapore in 2025.
Close to 80% of Singapore’s resident population lives in Housing and Development Board (HDB) flats. This makes space-efficient home transformation a practical priority.
Choosing a renovation firm affects your budget and everyday life. Credentials, scope clarity, and timely communication help prevent expensive delays and disputes.
In this blog, we explain how to identify the best interior design firms in Singapore. We also explain what separates a reliable partner from an average one. Finally, we profile ten homegrown studios worth shortlisting for your next HDB, condominium, or landed-home project.
What Should You Look for in a Leading Singapore Interior Design Firm?
The best interior design firms in Singapore combine transparent pricing and HDB renovation experience. They also show a documented track record of completed residential projects.
Choosing an interior design company in Singapore is about more than aesthetics. For flat renovations, a dependable firm should be listed in HDB’s Directory of Renovation Contractors. It should also carry adequate public liability insurance and provide a clear project timeline before work begins.
According to the Housing and Development Board, only HDB-registered renovation contractors may carry out renovation works in HDB flats (verified on 26 September 2026). This registration is a practical safeguard for homeowners because it confirms the firm understands HDB renovation guidelines and safety requirements.
Beyond compliance, look for firms that show real project portfolios, itemised quotations, and a willingness to explain material choices. The best interior designers Singapore homeowners recommend tend to be those who listen first and design second.
1. Verify HDB renovation credentials
For HDB interior design Singapore projects, confirm the firm is listed in the HDB Directory of Registered Renovation Contractors before signing any agreement.
2. Review completed project portfolios
Ask for recent case studies that match your flat type, whether it is a three-room resale flat, a five-room BTO, or a private condominium.
3. Compare itemised quotations
A trustworthy firm separates design fees, carpentry, electrical works, and materials so you can see exactly where your renovation budget goes.
How Much Does Home Renovation in Singapore Cost in 2026?
Use the ranges below only as an initial planning guide. Your final renovation cost depends on the agreed scope, materials, site conditions, and contractor quotation.
The cost ranges in this guide are indicative planning figures, not official tariffs or quotations. Flat size, age, hacking, wet works, custom carpentry, electrical work, and material selections can all change the final price.
BCA reported that construction demand remained high in 2025 and forecast total demand of S$47 billion to S$53 billion for 2026. However, it does not publish retail home-renovation price schedules. Treat the figures below as a budgeting starting point and compare like-for-like scopes before choosing a firm.
Always request at least three itemised quotations and clarify whether the price includes Goods and Services Tax (GST), debris removal, and defect rectification terms. The Inland Revenue Authority of Singapore (IRAS) reminds businesses to charge GST correctly. Homeowners should confirm the final figure is GST-inclusive before committing.
HDB flats
Budget S$30,000 to S$100,000 depending on flat size, resale condition, and whether you replace flooring, kitchen, and bathrooms.
Condominiums
Expect S$50,000 to S$150,000 for a full renovation, with higher costs for concealed systems and premium finishes.
Landed homes
Plan S$150,000 to S$500,000 or more, since structural changes, staircases, and larger floor areas multiply material and labour costs.
Estimated Home Renovation Costs in Singapore by Property Type
| Property Type | Typical Renovation Range | Key Cost Drivers |
|---|---|---|
| 3-room HDB flat | S$30,000 – S$60,000 | Flooring, kitchen, bathroom, basic carpentry |
| 5-room HDB flat | S$60,000 – S$100,000 | Full hacking, custom carpentry, electrical rewiring |
| Condominium | S$50,000 – S$150,000 | Concealed air-conditioning, premium finishes, management approvals |
| Landed home | S$150,000 – S$500,000+ | Structural works, larger floor area, multiple specialist trades |

What Are the Key Differences Between HDB, Condominium, and Landed Renovations?
HDB renovations follow stricter regulatory guidelines, while condominium projects may require management corporation approval. Landed homes offer the most design freedom but demand more complex project coordination.
HDB interior design Singapore projects must comply with renovation guidelines covering hacking, flooring, and wet works. The Housing and Development Board requires prior written approval for demolition or hacking works and restricts noisy works to specific hours.
Condominium renovations add a layer of approval from the management corporation, which may limit renovation hours, lift usage, and material delivery times. Landed homes give designers the most creative latitude, but they also involve longer timelines and more coordination across structural, electrical, and landscape works.
Understanding these differences helps you shortlist firms with relevant experience. A studio that excels at HDB flats may not be the best fit for a three-storey landed home, and vice versa.
HDB flats
Require HDB-registered contractors, permits for hacking and wet works, and adherence to strict renovation hours and safety rules.
Condominiums
May require management corporation approval, scheduled lift and material access, and compliance with applicable by-laws on noise and working hours.
Landed homes
Offer maximum design freedom but involve longer timelines, structural considerations, and coordination across multiple specialist trades.
HDB, Condominium, and Landed Renovation Requirements Compared
| Requirement | HDB Flat | Condominium | Landed Home |
|---|---|---|---|
| Contractor registration | HDB-registered renovation contractor required | No HDB registration required | No HDB registration required |
| Approval authority | HDB | Management corporation | Building and Construction Authority for structural works |
| Renovation hours | Strictly regulated | Set by management by-laws | More flexible but subject to noise rules |
| Design freedom | Moderate | Moderate to high | Highest |
How Do You Compare Interior Design Firms Before Signing a Contract?
Compare firms using a simple scorecard covering portfolio fit, quotation transparency, HDB registration, warranty terms, and communication responsiveness.
A structured comparison prevents costly mistakes. Start by shortlisting three to five firms, then request itemised quotations for the same scope of work so the numbers are directly comparable.
Ask each firm to state its defect liability period and aftercare process in writing. Terms and duration vary by contract. Confirm whether the firm provides dedicated project management, and check how quickly it responds during the quotation stage as a signal of post-sale service.
Businesses considering a paid directory can use our guide on how Singapore SMEs should choose a paid business directory. It offers practical selection criteria for showcasing renovation work.
Portfolio fit
Review completed projects that match your flat type and preferred style, not just the firm's most impressive showpieces.
Quotation transparency
Insist on itemised pricing for demolition, carpentry, electrical, plumbing, and finishing works so you can spot hidden costs.
Warranty and aftercare
Confirm the defect liability period and the process for reporting issues after handover, ideally in writing.
What Renovation Trends Are Shaping Singapore Homes in 2026?
Choose a design direction that supports your household’s routines, maintenance preferences, and storage needs rather than following a single must-have style.
Rather than treating any style as a must-follow trend, choose finishes and layouts that work for everyday life. Warm palettes, natural materials, planting, and flexible storage can be considered where they suit the home’s light, maintenance needs, and available space.
Multi-functional carpentry can be particularly useful in HDB flats. Built-in study nooks, concealed storage, and adaptable furniture may help households use limited floor area more effectively.
For sustainability-related choices, ask for product specifications and compare low-formaldehyde boards, recycled surfaces, and energy-efficient lighting against your budget and maintenance requirements.
Warm minimalism
Consider soft neutrals, natural wood, and layered textures if you want a more inviting, lived-in feel.
Biophilic design
Indoor plants, natural stone, and organic shapes can add a sense of calm and connection to nature in compact urban homes.
Multi-functional carpentry
Concealed storage, convertible furniture, and built-in workstations can help HDB and condominium residents make better use of limited floor space.
