One filed sale is not a range. Everything above rests on a single transaction, so there is no cheapest and dearest to report and no spread to read. It is what was filed here, once, over the period shown — not a level this address trades at. The nearby sales below are the wider evidence.

S$456S$843median psf, six equal-sized groups in this town

Blk 235 Hougang St 21 among 564 blocks in the same town. Outline: URA Master Plan planning area. Positions: OneMap. No distance or route is shown — only where things are. Shading is each block’s own median psf from its filed resales, in six equal-sized groups of this town.

What the floor is worth

This block—

Not enough filed sales at both ends of this block to compare it with itself. It needs 3 or more high and 3 or more low. The figure beside this one is the town, not here.

HOUGANG, typical block+8.7%

Middle of 29 blocks in HOUGANG that clear the bar — half fall between +5.5% and +11.8%. 2 came out negative — high floors sold for less in 2 of them.

Every band in HOUGANG, for reference. This pools all buildings in the town, so it carries the estates as well as the storeys — a town whose tall blocks are its newest ones will show a steeper climb than height alone buys. The two figures above are the ones that hold a building constant.

HDB Resale Flat Prices (data.gov.sg) · accessed 2026-09-10T21:08:48.055Z. Storey bands are the source's own — no floor number is inferred from them. A premium is a median of filed transactions, not a valuation of any home.

What's around

Straight-line distance from the building — the walk is longer, and how much longer depends on what is in the way.

A band is priority, not a place — and this is an indication, not MOE's answer. MOE measures home to school in a straight line, which is what is measured here. But it measures to the school's land boundary and this measures to the school's single registered coordinate, so a large campus reads as further away than MOE would find it. It also measures from the address on your child's registration, not from the block. A school near the line can fall either side of it once MOE measures it, and an oversubscribed school still ballots within a band. For the official category for a specific address, use OneMap's SchoolQuery.

The 16 most recent are listed, out of 106 in the index at this radius. The floor band is what URA and HDB publish; neither feed carries a unit number.

The afternoon sun, and what is approved in it247°–293°

Seen from here, the sun sets at 247° (WSW) in December and 293° (WNW) in June — a swing of 47° across the year. A window on one of those bearings takes the low sun for part of the year and none of it for the rest.

Today the sun drops below 15° at 06:04 pm and sets at 07:00 pm, arriving from 273° (W). Above that angle it is over the roof rather than through the window; near the equator the midday sun is almost overhead, which is why this is only ever about the last hour.

Which way does the unit face?

Nothing published says which way a unit points — not URA, not HDB. You are the one standing in it, or holding the plan. If the floor plan carries a north arrow, the plan reader will read it off and say so when it cannot.

6 permitted planning decisions sit on those bearings within 400m. What it means depends entirely on which:

2024-11-04	280m	260° W	2 storeys	Proposed amendment to approved erection of a 2-storey envelope control semi-detached house with attic

This does not tell you whether anything is blocked. A shadow needs the height and footprint of every building between you and the sun, and no public dataset here carries them — so none is drawn. What is above is the bearing the sun arrives on, which is astronomy, and what has been permitted along it, which is a filed decision with a reference number. Joining the two is yours. Bearings and distances are straight-line. A decision is permission to build, not a building: some are never started, and heights come from URA’s own wording, which states one about four times in five.
