If you own a conserved shophouse in Singapore, URA’s rules follow one idea, the “3Rs”: maximum Retention, sensitive Restoration and careful Repair. In a historic district, the front facade, roof profile and clay tiles, load-bearing party walls, timber floors and the airwell must be kept and restored. Modern comforts are allowed mostly at the rear and out of sight: screened air-conditioning units, a lift within the building envelope, solar panels on the rear roof slope and, in many cases, a roof mezzanine. Dormer windows and new basements are not allowed. Every change needs conservation permission from URA before work starts, and the Planning Act allows fines of up to $500,000.
Owning a shophouse means caring for a piece of the city’s story. The rules are detailed, but they are written down, and good architects know them well.
Quick facts
- Conserved buildings must follow URA’s Conservation Guidelines, built on the 3R principles.
- Owners must obtain conservation permission from URA, and approvals from other technical agencies, before starting any works.
- Where an original element must be replaced, URA must clear a one-to-one replacement.
- Rules differ by area type: historic districts, residential historic districts, secondary settlements and bungalows each have their own guidelines.
- Unauthorised works can attract a fine of up to $500,000, up to 12 months’ jail, or both, under the Planning Act 1998.
- Commercial shophouses are not restricted for foreign buyers; non-commercial shophouses need SLA approval.
What you must keep, and what you can change
This summary follows URA’s planning parameters and restoration guidelines for shophouses in historic districts such as Chinatown, Little India and Kampong Glam. Residential historic districts and secondary settlements have their own, sometimes more flexible, rules.
| Element | The rule |
|---|---|
| Roof | Keep the original profile, pitch, height and eaves; use traditional unglazed clay V-profile tiles; keep the timber roof structure |
| Party walls | Keep load-bearing walls intact, including the first 3 metres behind the first-storey shopfront |
| Floors | Keep original timber floor boards and joists, or original reinforced concrete floors |
| Airwell | Keep and restore its original size and location |
| Front facade | Restore original windows, doors, fanlights, vents and ornamental features; no clear glass in place of decorative panels |
| Five-foot way | Keep original granite edging; traditional floor materials are encouraged |
| Colours | Traditional paint schemes, ideally based on paint-scrape research |
| Not allowed | Dormer windows, new basements, enclosed balconies or verandahs, and in most cases strata subdivision |
Additions URA generally allows
- Air-conditioning condensing units, screened at the rear.
- A lift within the building envelope, placed at the rear if it protrudes.
- A new internal staircase in lightweight timber or metal.
- A roof mezzanine, with set-backs, and a jackroof within size limits, except on buildings with ornamental roof ridges.
- Skylights on the rear roof slope, covering up to 30% of it, and solar panels on rear slopes or flat roofs.
- A new rear facade with windows and doors, and a roof over the rear court below second-storey level.
How to get permission, step by step
- Check the building on URA’s conservation portal to see its conservation area and the guidelines that apply.
- Check its approved use; some uses are not allowed in Historic Conservation Areas, and a new business may itself need conservation permission.
- Appoint a Qualified Person, usually an architect experienced in conservation, to research the building and prepare drawings.
- Apply for conservation permission from URA, and approvals from BCA, SCDF and other agencies where needed.
- Start work only after approval, and keep the documents; they matter when you sell or refinance.
What happens if you get it wrong?
URA does prosecute. On 22 April 2026, it announced that an individual and a company had been fined $250,000 and $150,000 respectively for demolishing parts of a pre-war conserved shophouse at 32 Desker Road in Little India, including the residential front, rear facade and service block, without permission. The company must also reinstate what was lost. It was the first prosecution for unauthorised works to conserved buildings since the Planning Act was amended in 2017 to raise penalties.
Buying a shophouse: the points that catch people out
| Question | Why it matters |
|---|---|
| Is it commercial, residential or mixed use? | The approved use decides what you can do with it, and how stamp duty is charged; ABSD applies to residential property, so ask IRAS or your lawyer how a mixed-use unit is treated |
| Are you a foreign buyer? | Commercial shophouses are not restricted; non-commercial ones need SLA approval |
| Were past works approved? | Unauthorised changes can leave the new owner to put things right |
| What is the tenure? | Shophouses can be freehold, 999-year or 99-year leasehold, which affects value and loans |
The WahLiao Verdict
Buy a shophouse because you love what it is, not for what you hope to turn it into. The front, the roof and the bones stay; the comforts go at the back. Before you sign, have a conservation architect walk the building with you and read the approval history, and before you lift a single tile, get URA’s permission in writing. Do that, and you will enjoy one of Singapore’s most beautiful kinds of home with a clear conscience and a clean title.
Questions people ask
Can I add a swimming pool or a basement?
New basements are not allowed for shophouses in historic districts. Anything else at the rear, such as a water feature, depends on the specific guidelines and approvals, so ask your Qualified Person to check with URA.
Can I paint the front any colour I like?
No. URA asks for traditional paint schemes and colours, ideally based on research into the building’s original colours.
Can I replace rotten timber floors with concrete?
The original floor system is to be kept. Where an element must be replaced, URA must clear a one-to-one replacement, so repair like for like where you can.
Can I subdivide a shophouse into strata units?
Generally not. Strata subdivision of shophouses in historic districts is not allowed, except for some Art Deco or Modern-style buildings that meet specific criteria.
