For Societies

Why Nandivahan

A redevelopment means handing over the site your society has lived on for years. Here is how we think about that responsibility, and how the work runs.

One team, start to finish

A firm built to guard what is entrusted to it

Nandivahan plans and builds under one roof, rather than handing a site to an outside contractor and stepping back. The same team that studies your site is the one that hands you the keys — design architects, liaison architects and RCC consultants working alongside the firm, not apart from it.

Before you begin

A short guide for committees

The papers worth gathering first

Most of what a committee needs already exists — with the secretary, in an old file, or with the office that issued it. Gathering it early is worth doing for its own sake: it tells a society what it actually owns before anyone else tells them.

The property card records who owns the land and what is registered against it. The CTS plan shows the plot's boundaries and the city survey number by which it is identified in every document that follows. The conveyance deed is the instrument by which the land passed to the society — if no one can find it, that is the first thing to look into. The society registration certificate establishes the society as a body that can enter into agreements at all.

Two others carry more weight than they appear to. The member list, with each flat's carpet area, is the basis of every calculation anyone will later make about the building. And the existing building's approved plans and occupation certificate record what was sanctioned when it went up, which is not always what stands there today.

What decides how much can be built

How much can be built on a plot is not a matter of negotiation. It is set by regulation, and the same rules apply to anyone building there.

Four things drive it. The plot's area, as measured and recorded rather than as remembered. The width of the road it fronts, which matters more than most committees expect — a wider road generally permits more. The zone the plot falls in, which governs what may be built there at all: residential, commercial, or something mixed. And the regulation in force for that area, which sets out how these combine.

The practical consequence is that no one can tell a society what its plot will yield without first checking those four things. A figure offered before that has been done is a guess, however confidently it is given.

Carpet, built-up and saleable

Three words get used as though they were interchangeable, and they are not. The difference between them is where a great deal of confusion in redevelopment begins.

Carpet area is the usable floor area inside a flat — what a carpet would cover if laid wall to wall. It is the figure a member should care about, because it is the space actually lived in. Built-up area adds the thickness of the walls and certain other elements. Saleable area, sometimes called super built-up, adds a share of the common areas as well — lobbies, staircases, lifts — and it is the largest of the three.

Because saleable is the largest, it is the most flattering to quote. Two offers can only be compared if they are stated in the same term, and of the three, carpet area is the one with the tightest definition behind it.

The society's own advisors

A society entering redevelopment is dealing with people who do this professionally, while for the committee it is usually the first and only time. Appointing its own advisors is how a society closes that gap.

A project management consultant works for the society. They read the technical side of a proposal, check what is offered against what the plot can support, watch the quality of what is built, and translate between the committee and the people doing the work. A solicitor handles the documents — the development agreement above all — and makes sure a member understands what they are being asked to sign before they sign it.

The important word in both cases is "own". A developer will have its own consultants and its own lawyers, and they are doing their job properly when they act in the developer's interest. That is precisely why a society needs people whose duty runs the other way.

The approvals, in the order they come

Permissions come in a sequence, and each one has a specific meaning. Knowing which has been granted tells a committee more about where a project stands than anything visible from the street.

The IOD — intimation of disapproval, despite the name — is the list of conditions that must be satisfied before building can begin. It reads as a refusal and functions as a starting point. The commencement certificate is the permission to actually begin, granted once those conditions are met. Approval at plinth level comes next, where the authority checks that the foundation as built matches what was sanctioned, and further commencement is what allows the building to rise above it.

The occupation certificate comes at the end, and it is the one that matters most to a member: it is what makes the building lawful to occupy. Possession and the occupation certificate are separate things, and a committee should know the position on both.

Conveyance and deemed conveyance

Owning a flat and owning a share of the land underneath it are two different things. Conveyance is the transfer of the land and the building from the original developer or landowner to the society, and until it happens the society does not hold title to the ground its building stands on.

A great many societies discover this only when they begin thinking about redevelopment, because that is the point at which title suddenly matters. Deemed conveyance exists for exactly this situation: where the original owner has not executed the conveyance, a society can apply to have the transfer recorded without them.

For a committee the practical point is simple. Establish where the society stands on conveyance before going further, because it affects what the society is able to agree to.

Reading an offer

The headline carpet figure is the number every offer leads with, and it is the easiest thing to compare. It is also, on its own, close to meaningless — a larger figure in a vaguer document is not a better offer.

Read for specificity first. Is the accommodation described precisely enough that a member could recognise their own future flat in it: the area, yes, but also where it sits, what it opens onto, what comes with it? Are the arrangements around the move set out, or merely mentioned? Corpus, transit accommodation, parking and the treatment of shops or other non-residential space all need to be visible in the document rather than agreed in conversation.

Then read for what is absent. Silence in an offer is not neutral — anything not written down is something to be settled later, and later is a worse time to settle it. This is where a society's own solicitor and consultant earn their appointment: they are reading for the same things, with more practice at it.

This is general information. Your own advisors should confirm what applies to your plot.

How the work runs

A calm sequence, start to finish

  1. First conversation

    The first meeting is usually just that — a conversation. A committee describes the building as it stands: how many members, how the flats are laid out, what has stopped working. We listen, and say plainly whether redevelopment looks like the right route. Nothing is signed at this stage.

    It is worth noticing what a developer asks about. A firm that wants to understand the members — how many, what they hold, what they need — is thinking about the project a society will actually have to live through, not only the building that will stand at the end of it.

  2. Study of the site

    Before anything can be drawn, the plot itself has to be understood: its measured area, the width of the road it sits on, the zone it falls in, and the regulation that governs building there. The society's own documents come into it too — the property card, the CTS plan, the member list with each carpet area.

    This is where a plot stops being a general idea and becomes a specific one. Two buildings on the same lane can support quite different schemes. An offer made before this work has been done is not really an offer yet.

  3. A considered proposal

    A proposal sets out what can be built on the plot and what that means for the people already living there: the accommodation each member would move into, the arrangements around the move itself, and the obligations falling on each side. Carpet area, corpus and transit arrangements all belong to this conversation.

    Read it whole, rather than on one number. A committee comparing offers on the headline carpet figure alone is comparing the least informative part of them. What is specified, what is left loose, and what a member is being asked to put their name to — that is usually where offers genuinely differ.

  4. Appointment

    Consent comes before the resolution. A proposal is put to the members in meetings, where questions are asked and answered in the open rather than one at a time afterwards. Consent also works at two levels: the society agrees collectively through its general body, and members sign individually for their own flats. The collective decision does not replace the individual one.

    Appointment itself is a formal act of the society rather than a handshake. It goes through the general body, is recorded by resolution, and is set down in a development agreement and the authority that accompanies it — documents that are registered, and that govern everything which follows.

    This is the stage where a society's own solicitor matters most. Once the agreement is executed it becomes the reference for every question raised afterwards, so the time to read it closely is before it is signed.

  5. Approvals

    Permissions arrive in a set order, and each one releases the next. The IOD states the conditions a proposal must satisfy. The commencement certificate allows work to begin. Approval at plinth level confirms the foundation matches what was sanctioned. Further commencement takes the building upward. The occupation certificate is what finally makes it lawful to live in.

    A committee that understands this sequence can read a project properly. Progress on site and progress through the approvals are not the same thing, and it is the second that decides when a building may be occupied.

  6. Construction

    Nothing starts until the building is empty. Members move to alternate accommodation first, and the arrangements for that — where people go, and on what terms — are matters for the proposal and the development agreement rather than for the last minute. Settled there, the move becomes something a society can plan around.

    The work then follows its own order: foundation, then the frame floor by floor, then the services and finishes — the stage where a building that already looks finished from the road still has a great deal of work inside it.

    A committee is entitled to know who is actually on site. Some developers appoint an outside contractor and step back; Nandivahan plans and builds under one roof. That distinction decides who answers a member who has a question about their own flat.

  7. Handover

    Handover is not a single event. The occupation certificate comes first, then members take possession of their flats, and then the society takes charge of the common areas, the building's services, and its own records.

    There is paperwork to close as well: share certificates and membership records brought up to date against the new flats, and the position on the land itself settled. A committee that has kept its own advisors involved throughout tends to find this stage straightforward.
