Unit designation: Saleable, PAP, Common

What a unit is for, separate from its status: Saleable stock, a PAP unit kept for Project Affected Persons, or a Common unit housing an amenity; the designation decides who can be allotted or sold the unit and whether it shares the project's cost.

Unit designation: Saleable, PAP, Common

A unit's designation says what the unit is for. Saleable units are the stock you sell, and also the new flats society members and landowners receive. PAP units are kept for Project Affected Persons and can only go to a PAP tenant. Common units are common-use space (a society office, a gym, a refuge area) tied to an amenity, and are never allotted or sold. The designation is separate from the unit's status, which says where the unit is in its life right now.

How it works in NirmaanOne

The three designations

Every unit carries exactly one designation, Saleable unless you say otherwise:

Designation What it is for Who can take it
Saleable Stock for sale, and the rehab flats given to society members and landowners Buyers through estimates and bookings; society members and landowners through offers
PAP (shown as "PAP (reserved for PAP tenants)") Rehabilitation of Project Affected Persons PAP tenants only, through offers; never sold
Common (shown as "Common (amenity space)") Common-use space housing an amenity Nobody

A Common unit can name the Amenity it houses, picked from the organization's Amenities lookup (Society Office, Gym, Refuge Area and so on). Only a Common unit may carry one: "Only a Common unit can house an amenity (<amenity>); this one is <designation>". Changing a Common unit to Saleable or PAP clears the amenity with it.

Where it is set

  • On the Structure tab, in the unit panel's Designation field (and Amenity when Common). Picking an amenity needs the View permission on Lookups.
  • In the generator, per floor range or per position of a floor layout, so a rehab wing can be generated as PAP stock in one go.
  • Through the units Excel sheet's designation column.

The designation can be changed only while the unit is Available or Blocked. Once it is Reserved For Tenant, Allotted, Reserved For Buyer, Booked or Sold, an allotment or booking has relied on it, and the change is refused with "Unit <n> is <status>; release it before changing its designation from <designation>". This is what lets a PAP tenant's offer trust that the unit it holds is still a PAP unit.

What it changes

  • Offers to allottees. The unit picker on an offer draws from different stock for different allottees: a PAP tenant sees free or tenant-reserved PAP units, everyone else sees Saleable ones ("Pick the allottee first: PAP tenants and everyone else draw from different stock."). The rules behind it: "Unit <n> is a Common unit (<amenity>); it cannot be allotted", "A PAP Tenant can only be allotted a PAP unit; unit <n> is <designation>", and "Unit <n> is reserved for PAP tenants; a <category> cannot take it".
  • Estimates and bookings. A buyer's estimate and booking can only be for Saleable stock: "Unit <n> is <designation> stock, not for sale". An allottee's estimate and booking of their own allotted unit skip this check, which is how a PAP unit gets its booking and agreement.
  • The sellable count. The Projects list and the project overview count as sellable the units that are Saleable and still Available. PAP and Common units never count, whatever their status.
  • Structure views. Unit chips in the Floors view carry a "PAP" or "C" tag and a dashed border for Common; the Units grid tooltip notes the designation; the List view filters by it.
  • Cost of sales. When a revenue run shares the project's cost across units, the pool is the Saleable units, including the Saleable units given to society members and landowners (plus the PAP units allotted on issued, accepted or signed offers when the books' revenue policy treats rehab units as revenue). A booking of a PAP or Common unit takes no share of the cost; a rehab unit's cost sits on the member's offer under that policy, and is otherwise part of the price of the land.
  • Re-designating PAP stock. A PAP unit that the developer later buys back and wants to sell is released (the offer gives it up) and re-designated Saleable by hand; nothing does this automatically.

Amenity scope on the project

The amenities a project provides are listed on the project's Amenities tab, and each one is listed either project-wide or per tower, never both. A clubhouse or swimming pool is project-wide ("Shared by everyone in the project"); a refuge unit or society office is listed once on each tower that has it. The rules are enforced when you add or change a row: the same amenity cannot be listed twice project-wide or twice on one tower, and mixing the two scopes is refused with "This amenity is listed per tower; remove those rows before listing it project-wide" or "This amenity is listed project-wide; remove that row before listing it per tower". Each row may record a quantity, an area, a location ("Refuge floor 7") and notes.

The two uses of an amenity are one relationship. The Amenities tab says what the project offers; the Common unit's Amenity field says which unit houses it, and the amenity itself ties them: a per-tower row is housed in the Common units of that tower carrying the same amenity, a project-wide row in any Common unit of the project. The Amenities tab shows this under each row ("Housed in 1101 (floor 11)", "In Tower A, unit 1101", or "No unit assigned yet" on a per-tower row without a unit).

The list keeps itself in step with the units. Designating unit A-101 as Common with amenity Society Office lists Society Office on Tower A automatically (badge From units) unless it is already listed project-wide; the automatic row's quantity counts the units, its area sums their carpet areas and its location names them ("Floor 1, unit A-101"), and it goes when no unit of the tower houses the amenity any more. Editing such a row by hand makes it the user's own; listing the amenity project-wide replaces the automatic per-tower rows. Listing "Society Office" on Tower A by hand still creates no unit: a per-tower row without a Common unit simply reads "No unit assigned yet". Parking works the same way from the other side: a parking area on the Parking tab lists the Parking amenity on its tower (badge From parking, quantity = parking slots), or project-wide when an area belongs to no tower.

Business reason

On a Mumbai redevelopment the same tower holds three kinds of space with three different legal positions: flats sold on the open market, flats that the rehabilitation scheme sets aside for PAPs and must not be sold, and common areas that belong to the society. Keeping the designation separate from the status means a PAP flat can move from Available to Allotted to Booked and Sold along the rehab path while never appearing in the sales stock.

Example

Tower A of Skyline Heights has 120 units. The project manager generates them in two floor ranges, then changes six by hand:

  • Floors 1 to 3, 30 units (10 a floor), designation PAP: the rehabilitation floors for the 30 PAP tenants of the huts cleared from the plot.
  • Floors 4 to 21, 90 units (5 a floor), designation Saleable.
  • Six of those 90 set to Common in the unit panel: A-401 (amenity Society Office), A-402 (Gym), A-701, A-1401 and A-2101 (Refuge Area), A-1402 (Clubhouse). That leaves 84 Saleable units: 48 go to society members through offers, the rest are sold.

On the Amenities tab, Society Office and Refuge Area are listed on Tower A, and Clubhouse and Gym are listed project-wide, because Tower B shares them.

What each designation allows:

  • Mrs Kulkarni, a society member, is offered A-1203 (Saleable). Her offer's picker never shows A-201, a PAP unit: "Unit A-201 is reserved for PAP tenants; a Society Member cannot take it".
  • Mr Pawar, a PAP tenant, is offered A-201. Trying A-1203 on his offer is refused: "A PAP Tenant can only be allotted a PAP unit; unit A-1203 is Saleable".
  • A sales executive cannot book A-201 for a walk-in buyer even if it were free: "Unit A-201 is PAP stock, not for sale".
  • Tower A adds 84 to the project's sellable count at the start (the Projects list shows the whole project, Tower B included). Once the 48 members' offers are drafted with their units, Tower A adds only 36, because Allotted units are no longer Available.

When the books' revenue policy shares cost by area, does not treat rehab units as revenue, and Tower A has a cost budget of its own, the cost pool is Tower A's 84 Saleable units, members' units included. If they total 54,180 sqft on the project's chargeable area for buyers, a buyer's booking of A-1504 (645 sqft) carries 645 ÷ 54,180 = 1.19% of Tower A's cost; the 30 PAP units and six Common units carry none, and the PAP units' construction cost is part of the price paid for the land.

  • Unit areas and the chargeable areas: Carpet area (Mofa), RERA Carpet Area, Super Built-up AreaConcept

    Every unit carries up to three areas; two settings say which one money is worked out on: the chargeable area for buyers (what a Per Sqft price multiplies on a buyer's estimate) and the chargeable area for members and tenants (what a member's offer and an allottee's purchase are measured in).
