Ask how many apartments a project has and you will often get a range, a per-tower figure, or a number that appears nowhere official. TVS Emerald Altura publishes units per tower of 52 to 104 but no total; the figure of 975 that circulates is secondary. The total matters more than you would think, and it is findable.

Why the total matters more than it seems

Almost every useful ratio about a project has unit count as its denominator.

Homes per acre tells you density. Club area per home tells you whether you will get on a court. Homes per lift core tells you about your mornings. Parking spaces per home tells you about your evenings.

Get the unit count wrong and all four are wrong together, in the same direction, which is how buyers end up with a flattering picture of a project that is denser than they think.

It also matters at resale. A project of two hundred homes and one of two thousand have completely different liquidity and price-discovery characteristics — see the resale problem in small projects.

So it is worth a few minutes to establish properly rather than accepting whichever figure a page happens to carry.

Why developers publish ranges instead

Several reasons, most of them reasonable rather than evasive.

Counts genuinely change. Between launch, sanction and registration, unit mixes get revised. A tower planned with 96 units may register with 88 after a plan change.

Phasing complicates totals. On a project registered in phases, the total across all phases may not yet be fixed because later phases are not registered.

Per-tower figures are more useful to a buyer in some ways, since what matters to you is how many homes share your lift and your corridor.

A large total can deter buyers who read it as crowded, so some developers simply do not lead with it.

None of that is a problem provided you know where the authoritative figure lives, which is the filing rather than the brochure.

Where the real number is

The RERA filing states the number of blocks and the number of apartments, because a promoter must disclose what is being registered.

The important qualifier is for the registered phase. On a multi-phase project, one filing gives you one phase’s count, not the project total — and mixing a phase count with a project acreage is exactly the error that produces meaningless density figures.

So collect matched pairs: units and land from the same scope. Our guide to reading a RERA filing covers where each figure sits.

The sanctioned plan is the other authoritative source and it answers a slightly different question: what is approved to be built, which may exceed what has been registered so far.

Where the two differ, the gap is usually future phases. That is worth knowing, because a project registered for 500 homes on land sanctioned for 1,200 is going to feel very different in a decade.

Ask for both. It takes one extra question and it tells you what the place becomes rather than only what it is at handover.

How to ask for it so you get an answer

“How many units are there?” invites a round number. These four questions do not.

1. How many apartments are registered under the RERA number covering my tower?
2. How many blocks does that registration cover?
3. How many units are in my specific tower?
4. Is the project registered in one phase or several?

Question three is the one that most affects your daily life, and it is the one most readily answered because the sales team has the tower-wise breakdown in front of them.

Question four determines whether the number you have is the whole project or a part of it, which is the distinction that makes every subsequent calculation meaningful or not.

Then verify on the portal rather than relying on the answer. It takes ten minutes and it is the same visit where you read the declared completion date and the carpet area schedule.

If the answer you were given and the filing disagree, that is not necessarily a problem — plans change and registrations follow. But it is worth asking why, because the explanation usually tells you something about the project’s history.

The four sums to do once you have it

With a confirmed unit count and the matching land area, these take five minutes and tell you most of what matters.

Homes per acre. Units divided by acres. Under 50 is low density, 60 to 80 the Bengaluru norm, over 100 dense — see Lodha Beaumont Estate price breakdown.

Club area per home. Total clubhouse square footage divided by units. Thirty is reasonable, under twenty is thin, seventy-plus is boutique territory.

Homes per lift core. Units in your core divided by lifts serving it — see the lift ratio nobody asks about.

Parking per home. Total car spaces divided by units, plus visitor spaces separately.

Four divisions, four figures nobody publishes, and between them a far better picture of a project than any amenity list provides.

Write them in a single sheet across every project you are comparing, with the source of each number beside it. Two weeks later you will not remember which figure came from a filing and which from a hoarding.

That sheet is the difference between a decision you can defend and one you half-remember making — see marketing claims you can check with arithmetic for the rest of the checks worth running.

Figures above are drawn from published project information and are indicative. Verify any registration yourself on the Karnataka RERA portal before paying a booking amount.
