Method

How we source and check our figures

Primary source first, date on every figure, and both numbers shown when two sources disagree.

The short answer

The rule we work to

Illustrative image. This site publishes no photographs of completed projects, of anyone’s home, or of any team, and nothing here is a record of work we have carried out.
The short answer

Regulations come from HDB and link to the page they came from. Cost figures come from named third parties and carry the date they were published. Nothing on this site is a figure we remembered.

The process

How a figure gets onto a page

Illustrative image. This site publishes no photographs of completed projects, of anyone’s home, or of any team, and nothing here is a record of work we have carried out.
  1. Primary source first. If HDB publishes it, we quote HDB and link to that page. We do not paraphrase a regulator through a third party.
  2. Date it. Every rule carries the date we read the source. Every cost band carries the date its source published it.
  3. Label secondary sources. No regulator publishes renovation prices, so cost bands come from named third parties and are labelled as such rather than presented as official.
  4. Show disagreement. Where two sources give different numbers, both appear. We do not average them into a figure that belongs to nobody.
  5. Build-time enforcement. The components that render a figure require a source URL and a fetched date, and the build fails without them. The honesty rule is structural, not editorial.
Limits

What we will not publish

Illustrative image. This site publishes no photographs of completed projects, of anyone’s home, or of any team, and nothing here is a record of work we have carried out.

We do not publish customer reviews, star ratings or testimonials, because we have none. We do not publish photographs presented as our completed projects; the interiors on this site are illustrations of a described style or material and are captioned that way.

We do not display a licence number, an accreditation badge or a registration ID, because those are publicly checkable in Singapore registries and one that cannot be checked is worse than none.

Why there is no price list

And we do not publish package prices, because a published price is a number attached to a scope you have not agreed to.

Authorship

Pages here are published under the BTO Renovation SG desk rather than a personal byline. Research and drafting may be AI-assisted; every page is reviewed and edited by an accountable person before it ships, and every cost, regulation and timeline figure is checked against a named primary source with a fetched date.

Recruiting a credentialed reviewer is an open item, and it is not one we intend to close by inventing one.

Corrections

If a figure here is wrong or a rule has changed, tell us and we will fix it and re-date the page. The dateline at the foot of every page shows when it was last checked.

More about how we work is on about BTO Renovation SG, and the limits of what these figures represent are set out in the terms of use.

Does this work need an HDB permit?

Decision path for whether HDB renovation work needs a permit Four questions in sequence. Any yes means a permit is required before work starts. Only a no to all four means no permit is needed, and the guidelines still apply. Does it touch a wall? Yes, permit No, next question Does it touch wet areas? Yes, permit No, next question Does it touch the floor screed? Yes, permit No, next question Does it change the building envelope? Yes, permit No, none needed Works needing no permit still follow the guidelines and the permitted hours.
The dividing line is not how big the job looks. It is whether the work touches structure, wet areas, the floor screed or the building envelope.
