The best interior design firm HDB Singapore is The Interior Lab (TIL) if you want a named designer managing a BTO or resale from first site measure to final defect check. Two strong runners up are Weiken Interior Design for package pricing and Ciseern Interior for budget-conscious HDB owners. A good HDB interior design firm should show recent projects for the same flat model, quote line items for materials and HDB permit fees, and put a named site supervisor on the project. Compare payment milestones and the defect liability period before you sign.
Many HDB Owners Pick the Wrong Interior Design Firm
Many homeowners assume any renovation company can handle an HDB flat because the rooms are standard. That assumption causes trouble when the wall cannot be hacked, the BTO defect period is still running, or the HDB permit needs a specific submission. Some works also require approval before you start, and missing that step can stop the entire project. Condo and landed projects have more design freedom. HDB work runs on stricter rules and tighter timelines. If you are starting out, the HDB renovation archive is a useful place to browse wider.
My own search started after I collected keys to a 4-room resale flat in Tampines. I wanted one interior design firm to handle the space planning, carpentry, lighting and site coordination. I did not need a showroom speech. I needed someone who could explain which walls could be opened and how much a 4 room HDB design would really cost. I also wanted to know the real cost before committing, so I compared line items rather than showroom promises. I shortlisted firms with recent HDB case studies and asked each for an itemised quote. This list reflects that process, not a glossy brochure.

10 HDB Interior Design Firms Worth Calling
Each firm below has a different operating model. Some are package led, some are design led, and some are boutique. For a quick read on why an interior designer may beat a contractor, see four reasons to engage an interior designer.

How to Choose an HDB Interior Design Firm
The top interior design firms Singapore owners recommend all pass the same six checks. Ignore the showroom styling and start with HDB track record. Ask for recent projects in the same flat model, such as a 4-room BTO in Punggol or a resale 5-room in Tampines. If you are renovating a BTO, read this guide to renovating a HDB BTO flat. If your unit is resale, use this guide to renovating a HDB resale flat.
| Criterion | Why it matters | What good looks like |
|---|---|---|
| Track record with HDB flats | HDB layouts, BTO timelines and resale conditions differ from condos and landed property. A firm that knows HDB rules will quote more accurately and plan the site sequence better. | Recent portfolio projects for the same flat model, such as a 4-room BTO in Punggol or a resale 5-room in Tampines. |
| Itemised quotation | Lump-sum quotes hide costly exclusions. You need to compare materials, labour, carpentry quantities and HDB permit fees before signing. | A quote that lists material brand, model, quantity, labour, and a separate line for HDB permit submission. |
| Project supervision model | The designer may vanish after drawings are done. Someone must be on site to catch mistakes before they become expensive change orders. | A named site supervisor, fixed site visit schedule, and photo updates on WhatsApp after each work day. |
| HDB compliance knowledge | Not all walls can be hacked and some works need HDB approval. Wrong assumptions cause delays, fines or rework. | The firm can explain which wall types can be opened, which areas need HDB permit, and what cannot be touched in a BTO unit. |
| Contract and payment milestones | Large deposits expose you to project abandonment or slow progress. Payment should follow measurable completion stages. | Payments tied to stages like layout approval, carpentry installation and handover, with a written defect liability clause. |
| After-sales support | Touch-ups and minor defects show up weeks after handover. A firm with proper after-sales support will actually respond. | A written defect liability period with a clear process for submitting claims and a named person for after-sales issues. |
FAQ: HDB Interior Design Firms in Singapore
Do interior design firms for HDB charge a separate design fee on top of renovation cost?
Some do, some do not. Many HDB interior design firms fold design fees into the renovation package, while boutique studios may charge a separate fee or take a percentage of the total contract. You need to ask for a written breakdown before signing. A separate design fee is not automatically bad, especially if you receive detailed 3D visuals and custom carpentry drawings. The important thing is that the quote states whether the fee covers revisions, site visits and defect period work. If the fee is not listed, ask whether it is embedded in the material and labour lines.
Is it true HDB only allows certain interior design firms to submit renovation permits?
No. HDB does not restrict permit submissions to a list of approved interior design firms. The flat owner, or a contractor or designer acting on the owner’s behalf, can submit renovation works through HDB’s renovation portal or the appointed submission process. The firm must follow HDB’s renovation guidelines and submit the right documents for controlled works. What matters is that the interior design firm knows which works need approval, such as hacking certain walls or altering wet areas. A knowledgeable firm will prepare the submission without you chasing it.
What should I look for when comparing ID quotes for a 4-room HDB?
Look for an itemised quotation, not a lump sum. Each line should show material brand, model, quantity, labour in SGD and whether it covers the type of 4 room HDB design you discussed. Check the HDB permit submission fee as a separate line. Compare the carpentry quantities because two firms may quote different lengths for the same built-in wardrobe. Ask what is excluded, especially electrical, painting, false ceiling and haulage. Finally, confirm payment milestones tied to measurable completion stages, not a large first deposit.
Can I use the same interior designer for my BTO and my resale HDB, or should I pick one with BTO experience?
You can use the same interior designer if the firm has completed both BTO and resale HDB projects. The two flat types present different conditions. A BTO often needs less demolition but must respect the defect liability period and early renovation restrictions. A resale HDB may need more hacking, re-wiring and waterproofing checks. A firm with BTO experience will know what cannot be touched in a brand new unit and how to sequence work before the neighbourhood is fully occupied. Ask for recent projects in the same flat model.
How do I verify that a Singapore interior design firm is reliable before signing the contract?
Start with recent project evidence, not just showroom awards. Ask for photos and addresses of jobs completed in the last 12 months, and check whether the flat type matches yours. Look at the legal name and any Singapore business registration details, then search for reviews on multiple platforms, not just the firm’s own page. The best interior design firms in Singapore make verification easy because they explain their past work clearly. Ask for a copy of the contract and defect liability clause before paying. If the salesperson avoids putting details in writing, walk away.
