10 Best Interior Designers in Singapore for HDB and Condo Renovations (2026)

Renovating your BTO flat or resale HDB? Thinking about refreshing your condo before moving in? Choosing the right interior designer in Singapore can mean the difference between a dream home and a six-month nightmare. Here are 10 top-rated ID firms across different budgets and styles, with honest pricing and what each one actually does well.

How much does an interior designer cost in Singapore?

Renovation costs in Singapore depend heavily on the property type, scope of work, and the firm you choose. Here's a realistic breakdown for 2026:

• 3-room BTO (65 sqm): $30,000 to $55,000 for a full renovation
• 4-room BTO/resale HDB (90 sqm): $40,000 to $75,000
• 5-room HDB (110 sqm): $50,000 to $95,000
• Condo (100 sqm): $60,000 to $120,000
• Landed property: $150,000 to $500,000+

Design fees alone typically range from $3,000 to $15,000, though many firms bundle this into the overall renovation package. Always ask for a detailed quotation that separates design fees, carpentry, electrical, plumbing, and materials so you know exactly where your money is going.

What should you look for when choosing an interior designer?

Before you start scrolling through Instagram mood boards, here are the things that actually matter:

• HDB or BIA licence: Any firm doing renovation work on HDB flats needs to be HDB-registered. For private properties, check if they're registered with the Building and Construction Authority (BCA)
• Portfolio that matches your style: An ID who specialises in Muji-inspired minimalism might not be the best fit if you want industrial loft vibes. Look at their recent completed projects, not just 3D renders
• Clear quotation process: Good firms provide itemised quotes. Be wary of anyone who gives you a lump sum without breaking it down
• Warranty and after-sales: Most reputable firms offer 1 to 3 years warranty on carpentry and defects. Get this in writing
• Reviews on multiple platforms: Check Google Reviews, HardwareZone forums, and Qanvast. One platform can be gamed, but consistency across several is a good sign

Their carpentry work is consistently praised in reviews, and they use quality materials even at mid-range budgets. The team is relatively young but very design-forward. If you want a home that looks like it belongs on a design blog without spending landed-property money, they're a great pick.

Best for: Scandinavian and Japandi aesthetics, young couples, Instagram-worthy homes

3. Livspace Singapore

Location: Experience Centre at Suntec City

Price range: $30,000 to $70,000 for HDB flats

The tech-driven option. Livspace uses a platform-based approach where you can track your renovation progress online, approve materials digitally, and communicate with your designer through their app. They offer fixed-price packages for different flat types, which takes the guesswork out of budgeting. The trade-off is that the designs can feel a bit templated compared to boutique firms. But for first-time homeowners who want transparency and predictability, Livspace delivers.

Best for: Budget-conscious renovators, tech-savvy homeowners, fixed-price packages

4. Meter Square

Location: Showroom at Sin Ming (near Marymount MRT)

Price range: $45,000 to $100,000 for HDB flats

A mid-to-premium firm that's earned a loyal following through word of mouth. Meter Square is known for thoughtful space planning, especially for smaller flats where every square foot counts. Their designers spend a lot of time understanding how you actually live before proposing layouts. The carpentry is top-notch and they work with reliable subcontractors. Expect a longer wait for a slot during peak BTO collection periods.

5. Design 4 Space

They're straightforward with pricing and their project coordinators are good at flagging potential issues before they become expensive problems. The designs lean practical rather than avant-garde, which is exactly what many homeowners need. Great option if you want a reliable renovation without surprises.

Best for: Budget-friendly HDB renovations, practical designs, no-fuss approach

6. Third Avenue Studio

Location: Studio at Joo Chiat (near Paya Lebar MRT)

A boutique firm that focuses on high-end residential and landed properties. Third Avenue Studio treats each project like an art piece, with bespoke furniture, custom lighting design, and curated material palettes. They work with a smaller number of clients at any given time, which means more attention on your project but also longer lead times. Their completed projects have been featured in SquareRooms and Home & Decor magazines.

Best for: Luxury condos, landed properties, bespoke design, magazine-worthy interiors

7. Lemonfridge Studio

Location: Studio at Lavender (near Lavender MRT)

Price range: $50,000 to $110,000 for HDB and condos

Specialises in warm, Muji-inspired minimalism with plenty of natural wood and neutral tones. Lemonfridge has developed a distinct aesthetic that's instantly recognisable. They're very detail-oriented with joinery and built-in storage solutions. Communication during the renovation process is a standout, with regular photo updates and site visits. Popular with young families who want a calm, clutter-free home.

Best for: Muji minimalism, warm wood tones, young families, detailed joinery

Price range: $35,000 to $85,000 for HDB flats

One of Singapore's largest ID firms with over 20 years of experience and thousands of completed projects. Weiken's scale means they have strong relationships with suppliers and can often get better material prices. They offer a wide range of styles from contemporary to industrial to modern classic. The size can be a double-edged sword since your experience depends heavily on which designer you get assigned, so ask to see their individual portfolios.

Best for: Wide style range, competitive pricing, established track record

9. Fineline Design

Location: Showroom at Henderson (near Redhill MRT)

Price range: $55,000 to $120,000 for HDB and condos

Fineline's designers have a knack for making standard HDB layouts feel more spacious through clever use of mirrors, lighting, and open-concept configurations. They've won multiple design awards and their after-sales service gets consistently good reviews. Worth considering if you want a polished result without going full luxury pricing.

Best for: Clean contemporary design, open-concept layouts, award-winning portfolio

10. Notion of W

Location: Studio at Kaki Bukit (near Kaki Bukit MRT)

Price range: $40,000 to $90,000 for HDB flats

A rising name that's gained popularity through stunning before-and-after transformations shared on social media. Notion of W specialises in modern contemporary and industrial styles, with strong attention to lighting design. Their founder is hands-on with most projects, which keeps quality consistent. They're particularly good with resale HDB flats that need more extensive hacking and reconfiguration. Booking slots fill up fast, so reach out early.

Best for: Resale HDB transformations, industrial style, lighting design, social media-popular

How long does a typical renovation take in Singapore?

Timelines vary based on the scope of work:

• BTO flat (basic renovation): 6 to 8 weeks
• Resale HDB (with hacking): 8 to 12 weeks
• Condo: 8 to 14 weeks
• Landed property: 4 to 8 months

Add 2 to 4 weeks on top for the design and quotation phase before construction starts. During peak periods (typically April to June when BTOs get their keys), lead times can stretch further. It's smart to start talking to IDs at least 3 months before your key collection date.

What are common renovation mistakes to avoid?

• Not getting at least 3 quotes: Prices can vary by 30% to 50% for the same scope of work. Compare apples to apples by asking each firm for itemised breakdowns
• Choosing based on 3D renders alone: Pretty renders don't guarantee good execution. Ask to visit a recently completed project or check for photos of actual finished homes
• Skipping the contract details: Make sure payment schedules, warranty terms, and variation order processes are spelled out clearly. The CaseTrust-RCMA accreditation is a good trust signal
• Over-renovating for resale: If you're likely to sell in 5 to 7 years, focus on quality basics rather than highly personalised built-ins that the next owner might rip out
• Forgetting about storage: Singapore homes are small. Prioritise smart storage solutions over purely aesthetic features. You'll thank yourself in two years

Where can you find reliable reviews of interior designers in Singapore?

• Qanvast: The most popular renovation platform in Singapore. You can browse portfolios, read reviews, and request quotes from multiple firms at once
• Google Reviews: Look for firms with 50+ reviews and a rating above 4.5. Read the detailed reviews, not just the stars
• HardwareZone forums: The Reno & Interior Design subforum has real homeowner experiences, including the occasional cautionary tale. Worth browsing
