For East Coast HDB flats, Weiken Interior Design is the top pick due to its established HDB paperwork process and large designer pool. Choose Ciseern by K&T if you are a first-time BTO owner wanting a bundled package. Pick Space Atelier if you prioritise a distinct design outcome over the lowest per-foot price. Always verify the specific designer and supervisor assigned to your site, as workload varies significantly between teams.

Intro
Many homeowners believe the cheapest contractor is the safest bet for an HDB renovation in East Coast. This is a misconception. HDB rules on hacking, windows, and flooring are strict, and a firm that cuts corners on permits or scope will stall your project or leave you with defects. The real cost is in the hidden exclusions and the speed of after-sales response.
I compiled this list to help you decide between design-led studios and volume-driven firms. It is hard because most firms look similar online. The difference lies in who actually touches your walls and how they handle the paperwork. Use this guide to compare scope, not just price.
Quick picks
Choose Weiken Interior Design if you want a wide choice of design packages and the option of switching designers if the fit is wrong. Choose Ciseern by K&T on a tighter budget if you want one package covering the usual scope for a BTO or resale flat. Choose Space Atelier for a design-led outcome if you care more about the aesthetic than the cheapest per-foot price.

The list
1. Weiken Interior Design
Weiken is a large interior design and renovation firm handling HDB flats, condos, and landed homes. They run a showroom-led sales process with a big bench of designers. This model allows you to request a change in designer if the initial fit is wrong, which is a rare benefit in the volume market.
What’s good
- Big designer pool, so you can request a change without leaving the firm
- Broad portfolio covering 3-room, 4-room, 5-room, and executive flats
- Established internal process for HDB renovation permits and paperwork
What to watch
- Volume is high, so the individual designer and site supervisor assigned to you matters more than the brand
- Package pricing tends to exclude some items, so compare the scope line by line rather than the headline
Who it suits
Homeowners who want a wide choice of design packages and the option of switching designers if the fit is wrong. It is less suitable for owners who want a single, fixed point of contact from day one to handover.
Price
Mid to premium, verify current quote.

2. Ciseern by K&T

What’s good
- HDB flat experience across many blocks and layouts
- Package structure that is easy to compare against other quotes
- Familiar with the common HDB rules on hacking, flooring, and windows
What to watch
- Bundled packages can make it harder to see what you are paying for each item
- Ask what happens if your flat needs extra work not in the package
Who it suits
First-time HDB owners who want one package covering the usual scope and a firm that handles flats all day. Look elsewhere if you require a highly customised, non-standard layout that falls outside their core packages.
Price
Value to mid, verify current quote.

3. Rezt & Relax Interior

What’s good

- Handles both HDB and private property projects
- Consultation-first approach suits buyers who need to see options
What to watch
- Confirm who your actual project designer is, since showroom staff and site staff are not always the same people

What to watch
- May be priced above the budget end of the HDB market
- Small flat jobs may not get the same attention as larger contracts

5. Space Atelier

- Good fit for owners with a clear aesthetic in mind
What to watch
- Design-led firms can be less flexible on scope and substitutions

What’s good

- Residential renovation focus
What to watch
- Smaller firms have less buffer if a designer leaves mid-project, so get the succession arrangement in the contract
- Verify recent project photos are genuinely the firm’s own work
Who it suits

How to choose
Use this table to evaluate your shortlist. Focus on the criteria that matter most to your specific flat type and budget.
| Criterion | Why it matters | What good looks like |
|---|---|---|
| HDB paperwork and permit handling | Hacking, floor tiling, and window replacement need HDB approval. A firm that gets this wrong stalls your project. | The firm names the specific works that need approval, tells you who submits the application, and shows you the permit before work starts. |
| Itemised quotation, not just a lump sum | Renovation quotes for the same flat can differ by tens of thousands. A lump sum hides what is excluded. | A line-by-line quote showing quantity, material, unit rate, and whether removal, disposal, and protection are included. |
| East Coast coverage and site access | A firm based an hour away may still take your job, but site visits and snag fixes are slower. | An active cluster of projects in Bedok, Marine Parade, Siglap, Eunos, Kembangan, or Tampines, and a supervisor who can be on site the same day. |
| Designer and supervisor workload | Most renovation complaints trace back to a designer juggling too many sites. | The firm tells you how many concurrent projects your designer is handling and who covers if they go on leave. |
| In-house versus subcontracted trades | Carpentry, electrical, plumbing, and tiling quality depends on who actually holds the tools. | A clear answer on what is done in-house, what is subcontracted, and what warranty applies to each trade. |
| Defect and after-sales response | Issues show up weeks after handover, when your leverage is lowest. | A written defect liability period, a named contact for after-sales, and a stated response window for site visits. |
| Reviews matched to your flat type | A firm that shines on landed property may run a 4-room flat as a small side job. | Recent reviews and case studies from comparable HDB flat types in the last 12 months, with photos you can cross-check. |

FAQ
How much does it cost to renovate a 4-room HDB flat in the East Coast?
Expect to pay between SGD 20,000 and SGD 40,000 for a standard 4-room HDB renovation. This range covers basic carpentry, tiling, and painting. Costs rise if you include high-end finishes, extensive hacking, or custom joinery. Always get an itemised quote to see where the money is going. Prices vary by firm and the extent of the work.
Do I need HDB approval for hacking walls and changing floor tiles?
Yes, HDB approval is required for hacking walls and changing floor tiles. You must submit an application before work begins. The firm should handle this for you, but you must verify the permit is approved. Non-structural walls can be hacked, but you must not touch load-bearing walls. Check the HDB guidelines for your specific flat type.
Should I hire an interior design firm or a renovation contractor?
An interior design firm offers a full package including design, materials, and project management. A renovation contractor focuses on the execution of the works. If you have a clear design vision, a firm is better. If you just need to get the job done on a budget, a contractor may suffice. Many firms in this list offer both services. Decide based on your need for design support versus cost control.
How long does an HDB renovation take from key collection to moving in?
A typical HDB renovation takes 8 to 12 weeks from start to finish. This includes demolition, carpentry, tiling, and painting. Delays can occur if HDB approval is slow or if there are changes to the scope. Plan to move in at least 4 weeks after the scheduled completion date to allow for snagging and cleaning. Factor in buffer time for any unexpected issues.
Are renovation firms in Bedok or Kaki Bukit cheaper than those in town?
Not necessarily. Price is determined more by the firm’s positioning and scope than their location. Firms in Bedok or Kaki Bukit may have lower overheads, but this does not always translate to lower prices for the client. Some local firms position themselves as premium. Compare itemised quotes rather than assuming location dictates cost. The key is the value of the work provided.
