Tampines North Drive 1, Rowell Road, Simei Street 4 and Yuan Ching Road

Why address searches behave differently

A user who searches an HDB estate is usually comparing a market. A user who searches an exact address is often standing much closer to a decision. They may have a listing, a postal code, a block number, or a map result. The page needs to answer quickly: what does this address map to, and how strong is the data?

This query batch has four HDB-style address clusters: Tampines North Drive 1, Rowell Road, Simei Street 4 and Yuan Ching Road. Two are clean block searches. Two are messier because the exact number searched does not match the HDB block numbers in our current address file.

That is not a reason to hide the result. It is a reason to be precise. If the exact address is not in the residential file, say so through the content and point to the closest residential street page instead.

What to make of this

For HDB resale, the read should move from estate to street to flat type, then finally to the block story. The main anchors here are address clusters 4 (HDB street pages with query demand) and deepest resale street Simei Street 4 (1,441 resales). The estate median is a good first read, but the street and flat type are where the price starts to feel real.

Tampines North Drive 1 HDB in Tampines is the first row I would open, with last 12m resale $810,944 and last 12m rent $3,600. If the top comparison does not match the flat type or street you care about, do not force it. A less glamorous but closer comparable is usually more useful.

What I would check next

I would move from the estate page into the street page, then filter mentally by flat type. A 4-room resale and an executive flat can make the same estate look very different.

If the asking price is above the street evidence, the flat should have a reason buyers can see: lease balance, condition, floor, view, renovation, larger area or stronger daily convenience.

1 Tampines North Drive 1 should start at the street page

Tampines North Drive 1 has 426 resale records in the current HDB resale file, with an all-time median resale price of $790,000. The last 12 months are more useful for current checks: 136 resales, median price $810,944, and median PSF around $765 psf.

The rental side is smaller but useful. The street has 61 rental records, with a last-12-month median rent of $3,600 across 19 rentals. That gives renters and landlords a starting point before checking the exact block.

The residential block entries in our file include Blk 608A, Blk 608B, Blk 608C and Blk 609A. Those are the HDB blocks to open from the street page. A search for "1 Tampines North Drive 1 T Space" should not be read as HDB resale evidence for T-Space. The residential data we have is for the HDB blocks on Tampines North Drive 1.

Tampines North Drive 1 is a newer resale market

The resale records on Tampines North Drive 1 are recent compared with older HDB streets. In 2026 YTD, the street shows 54 resales, a median price of $812,444, and median PSF around $774 psf.

That newer-market pattern matters. The all-time median is not dragged down by decades of old transactions the way some mature streets are. The last 12 months and 2026 YTD should still be checked, but the gap between old and new evidence is less extreme than on older streets.

For a buyer, the block-level check is still necessary. Newer clusters can have different stacks, views, floor levels and flat sizes. The street median gives the first guardrail. The exact block and flat type decide whether the asking price belongs above or below it.

10 Rowell Road is a mismatch in the HDB file

Rowell Road has a useful HDB street page, but the exact query "10 Rowell Road" does not map to an HDB block in the current address file. The HDB blocks we have for Rowell Road are Blk 639, Blk 640, Blk 641 and Blk 642. That distinction matters because a visitor may be looking at a non-HDB address or a nearby point of interest.

The Rowell Road HDB street page itself has 410 resale records. The last 12 months show 9 resales, median price $770,000, and median PSF around $685 psf. The sample is smaller than some suburban streets, so recent records should be read carefully.

Rent data helps fill in the picture. Rowell Road has 0 rental records, with last-12-month median rent around -. That is useful for central-area HDB rental checks, but it still does not make "10 Rowell Road" an HDB block match.

How to use the Rowell Road result

If the user searched Rowell Road because they care about HDB flats, the street page is the right destination. It gives the resale and rental evidence for the residential blocks we track.

If the user searched 10 Rowell Road specifically, the page should make room for uncertainty. The current HDB block file does not support that exact address. The safest product behavior is to show the Rowell Road HDB street result while also making it clear that the exact block was not found.

This is where better search grouping matters. A perfect match should feel different from a nearby street match. The content layer can help, but the search UI should also separate exact residential matches from close street matches.

11 Simei Street 4 is another exact-address mismatch

Simei Street 4 has a large HDB street page, with 1,441 resale records and an all-time median resale price of $372,000. The last 12 months show 18 resales with a median price of $700,944 and median PSF around $595 psf.

The exact query "11 Simei Street 4" does not map to an HDB block in our current address file. The HDB block set on this street starts with entries such as Blk 221, Blk 222, Blk 223 and Blk 224. So the site should not pretend that Blk 11 exists in the HDB resale data.

The rental file is stronger here than it is for some smaller streets. Simei Street 4 has 250 rental records, with last-12-month median rent around $3,650 across 48 rentals. That makes the street page useful even when the exact query number is not a block match.

Simei Street 4 should be read by block

Because Simei Street 4 has many resale records, the street median is only the first read. A buyer should narrow into the block list, then compare flat type, storey range and remaining lease.

The street's 2026 YTD resale median is $677,500, while the last-12-month median is $700,944. The difference between those two periods is not a final trend call, but it tells the buyer to check the latest transactions rather than relying only on the all-time median.

For tenants, the last-12-month rent signal matters more than the all-time rent. Rental markets move faster than resale history. If an asking rent is far above the recent street median, the unit needs a visible reason.

Yuan Ching Road has clean block demand

Yuan Ching Road is the cleanest block-search cluster in this list. The queries point to Blk 121, Blk 122 and Blk 138D. The street page has 393 resale records, with last-12-month median price $565,000 and median PSF around $728 psf.

The rental side has 153 records, with last-12-month median rent of $3,050 across 33 rentals. That is enough to support a first rent check before narrowing into a block.

The important point is that the blocks are not interchangeable. Blk 121 has 96 resales, median resale $257,250, and median rent $2,200. Blk 122 has 76 resales, median resale $265,000, and median rent $2,000. Blk 138D has 59 resales, median resale $665,000, and median rent $3,275. A person searching 138D should not be shown only the whole-street median without the block context.

121 and 122 are older low-price anchors

Blk 121 and Blk 122 Yuan Ching Road have lower resale medians than Blk 138D in the current block summaries. Blk 121 has median resale price $257,250 and median rent $2,200. Blk 122 has median resale price $265,000 and median rent $2,000.

That gap is not just noise. It likely reflects a mix of age, flat type, block characteristics and buyer demand. The street page should help a buyer avoid comparing a newer or higher-price block with older blocks as if they were the same product.

For sellers, the same rule applies. A strong sale in one Yuan Ching block is not automatically the anchor for every block on the street. Use the block evidence first, then widen to the street only when the block sample is too thin.

138D needs its own block read

Blk 138D Yuan Ching Road has 59 resale records in the address file, with median resale price around $665,000 and median PSF around $654 psf. Its rental median is around $3,275 across 28 rentals.

That is a different story from Blk 121 and Blk 122. The visitor who searches 138D is probably looking at a more specific cluster. The product should make the anchor link land cleanly on the block, and the page copy should explain why the block number matters.

This also supports the longer-term case for block-level HDB pages. Street pages work today, but high-intent block searches are telling us that some users want the next layer down.

What to fix in search behavior

Exact matches should be obvious. If a query matches a block and postal code, the result should show the block first. If a query only matches the street, the result should say street-level match. If the query appears to point outside the residential file, we should avoid forcing it into an HDB block answer.

This matters for trust. A user who searches 640848 or 121 Yuan Ching Road is testing whether the site understands Singapore addresses. If the result lands one block lower, one anchor below, or on a broad page without context, the data may be correct but the experience feels wrong.

The content here is the first layer. The next product layer is cleaner grouping: exact project, exact HDB block, street match, estate match, and nearby suggestions. That order matches how people think when they search by address.

The practical reader path

For Tampines North Drive 1, start at the street page, then open the residential block anchors such as 608A, 608B, 608C and 609A. Ignore T-Space as an HDB resale signal unless we add a separate non-residential data product later.

For Rowell Road and Simei Street 4, use the HDB street page but keep the exact-number caveat visible. The street has residential evidence. The exact searched address may not be an HDB block in our current file.

For Yuan Ching Road, go straight to the block anchors. The query demand is already block-specific, and the data is strong enough to explain why 121, 122 and 138D should not be blended into one easy answer.
