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.

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.

BUKIT BATOK, typical block+11.1%

Middle of 45 blocks in BUKIT BATOK that clear the bar — half fall between +7% and +14.2%. 1 came out negative — high floors sold for less in 1 of them.

Every band in BUKIT BATOK, 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.

The 17 most recent are listed, out of 121 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 06:00 pm and sets at 06:56 pm, arriving from 269° (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.

Nothing with planning permission sits on those bearings within 400m. That is a fact about this radius and these bearings, not a guarantee of a view — an application not yet decided does not appear here, and neither does anything further out.

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.

Leaving it unticked is fine — the tools work either way, and I'll still reply to this enquiry. I don't sell or share your details.
