Apartment Building Architecture in Salt Lake for Plot Owners

Apartment Building Architecture in Salt Lake for Plot Owners

If you already hold a plot in one of the Salt Lake blocks, or you are buying one and want to know what can be built on it before you sign, the real question is not which elevation style you like, it is how much usable building the land will carry once the setbacks, the stair and lift core, the parking at ground level and the neighbours' walls have taken their share. That arithmetic is the design, so this page is about the massing, the plan, the structure, the elevation and the Bidhannagar sanction route.

Studio Contour is an architecture and interior design studio based in New Town, working across the Salt Lake, New Town and Rajarhat belt, founded in 2014, with 330+ buildings delivered. The principal architect is Sumana Kumar, and on a plot project she stays with the drawing through sanction and through site rather than handing the file to a junior once the agreement is signed, because the decisions that cost real money on a tight plot are the small ones taken at the boundary, at the stair and at the shaft. The wider picture sits on our Salt Lake area page and on architecture and interior design across Salt Lake.

One thing worth saying at the very start, right, is that nobody can tell you your buildable area from a photograph of the plot or from the sector number, because ground coverage, setback and height permissions vary by plot, by the road in front of it and by the category the plot falls under, so all of it has to be confirmed for your specific plot against the current rules before any area statement means anything.

What the Salt Lake grid gives you, and what it quietly takes away

Salt Lake, written in official records as Bidhan Nagar, was laid out on reclaimed land as a planned township, and that grid of blocks and sectors is why the area is comfortable to build in. The catch here is that the same planning produced plots decent in frontage but tight in depth, so with most neighbours built up to the boundary decades ago, your light and air will come from your own setbacks, your own light court if you make one and your own terrace. The stock around you runs from the sixties through the nineties, and beside it now are G+3 and G+4 rebuilds on plots of the same size, so a taller rebuild is normal here, though yours will be read from the road against a lower, older neighbour. Sector V, the separate commercial and information technology belt, absorbs the office demand, so these blocks stay residential in character.

The survey and the site walk that decide the building

Before any plan is drawn the plot gets measured properly, which means the corners, the actual road edge rather than the assumed one, the level difference between road and plot, the height of both neighbours' walls, where their windows and toilet shafts fall, and where water runs in heavy rain. Basically, the survey is not a formality to attach to the file, it is the document the design is argued from, because on a tight plot a few inches at the boundary decides whether a bedroom window has a usable outlook or stares into somebody's brick. Where an existing structure is coming down, the same walk records the old foundation as far as it can be judged, the water connection and drain outlet, and how a demolition crew gets machinery in and debris out.

Massing, which is really the question of floors and where the core goes

The first real design decision is the envelope, and it comes out of the floor area and ground coverage your plot is permitted, the setbacks to be left on each side and the height the plot can carry given its road, all of which vary plot to plot and must be confirmed against the current rules rather than assumed from whatever the neighbour built in 2009. The idea behind floor area ratio is simply the relationship between how much floor you may build and how much land you have, and the work lies in spending that allowance well rather than merely reaching it.

Where the staircase and the lift sit governs everything else, because a core in the middle of a narrow plan gives you two stub corridors and dead corners on every floor, while a core pushed against one flank wall, usually the side with least to gain from windows, lets the floor open into one continuous usable area. Parking is worked backwards from that, since a car has to turn in off the block road, clear the gate, clear the column grid and still leave a lobby entry that is not a squeeze past a bumper, and that one constraint has reorganised more upper floor plans than any aesthetic preference. A completed residential building on a plot of this kind is Cornerstone House project in Salt Lake, which is an example of that category of work.

Plan logic, stacking and the shafts nobody looks at

On a plot where floors repeat, the plan is mostly a stacking problem, because toilets, kitchens and shafts want to sit directly above one another so drainage runs vertically and short rather than crawling sideways under a slab hunting for a stack, and the moment a kitchen moves on the second floor for the sake of a view, the plumbing below gets redrawn or the owner accepts a slow drain that will be blamed on the plumber for twenty years. Inside the flat, open planning works well here because a living and dining space borrowing light from one good opening reads far larger than two small rooms with one window each, and the reasoning is set out in Open-Plan Living and Dining Design for Salt Lake Flats, while the detailing where a dining wall meets storage is covered in Crockery Unit Design for Salt Lake Dining and Kitchen Spaces. Bathrooms are where the compromises show first, so our approach to bathroom design starts from the shaft, the slope and the drainage.

Elevation, daylight and the long humid stretch

This city gives you a long humid stretch and then a serious monsoon, so openings are placed to move air through the flat rather than merely to look balanced from the road, because natural ventilation across a plan with openings on two sides does more for comfort and for the electricity bill than equipment added afterwards. Where only one external face is available, the plan has to make a path for air with a light shaft or small internal court, which costs floor area, so it becomes an option presented with its consequence attached. The elevation features that earn their keep here keep water off the wall and sun off the glass, projecting chajjas sized for the actual sun angle, drip grooves so water does not track back along the soffit, a terrace with real slope and waterproofing carried up the parapet, and a plinth high enough for the water the block road holds in a bad hour of rain.

Structure, demolition and the Bidhannagar sanction route

Most new buildings on these plots are framed in reinforced concrete, and the column grid is not a free choice, because it has to agree with the parking layout below it, the stacking above it and the setback lines on both sides, which is why the structural engineer joins while the plan is still movable rather than being handed a finished one. Foundations next to a neighbour's old wall need care in design and in sequence, and where a house is coming down the party wall condition, the demolition method and the protection of the adjoining structure are the architect's problem as much as the contractor's, while that sanction route has its own sequence and paperwork, set out step by step in Bidhannagar Municipal Corporation Building Plan Sanction for a Plot With an Existing Structure to Demolish in Salt Lake.

Salt Lake's building authority is Bidhannagar Municipal Corporation, which is worth being precise about, because New Town plots fall under NKDA and the two get confused by people who built in one and are now buying in the other. We prepare the drawings and run them through the Bidhannagar sanction process as part of the work, so the owner is not carrying a set between the person who drew it and somebody else defending it, and the wider rule framework is covered in Bidhannagar Building Rules for Salt Lake Homes. Sanction drawings and building drawings are not the same thing either, since a sanctioned plan proves compliance while a working set tells a mason where the wall centre line falls and the electrician which wall carries which conduit, which is why Working Drawings and GFC Sets for a Salt Lake Build exists separately, and a finished building showing what that sequence produces is Residential Building Project in Salt Lake, an example of that category of work.

Options with a cost consequence attached to each one

A budget usually goes wrong on a plot build not through one large mistake but through thirty small decisions each taken without a number attached, so by the time the owner adds them up the figure has moved and nobody can say which choice moved it. Our method is to present options with the cost consequence stated at the time of the choice, so a change of flooring, a light court or a lift of a different class is answered with what it does to the figure before it is approved, and we do not publish rates here because a rate quoted without a plot, a specification and a date is misleading. Where vastu is part of the brief, and on family plots here it often is, it is better handled at the planning stage than retrofitted, because the entrance, the kitchen position and the water tanks can usually be resolved inside a good plan if they are known from the first sketch, which is how we approach vastu compliant design. Because architecture, interiors and the Bidhannagar submission sit with one team, the owner is not carrying information between three vendors, and title, mutation, loan structure and tax treatment go to your own lawyer, your chartered accountant and your lender.

When a different kind of provider suits you better

Not every plot owner needs a studio like ours. If you have inherited a plot, you want a straightforward two unit building with no design ambition, and your priority is the lowest delivered cost with somebody else taking every decision, a competent turnkey contractor working off a standard plan will get you a building and you will probably pay less for it, because that business model earns on construction volume and treats drawing as overhead. If your sanction is in hand and the design is settled and you only need a submission set redrawn, a drafting service will do that faster and cheaper than a design studio ought to. Where our structure pays for itself is the project with constraints in it, a tight plot, a demolition, a family splitting floors between members with different needs, a sanction route with a complication, or an owner who will live there for thirty years and cares what the monsoon does to the west wall.

Starting on your own plot

If you hold a plot in a Salt Lake block and want to know what it will carry, the first useful step is a measured look at the land together with the current rules for that specific plot, after which the massing conversation can be had with real numbers instead of assumptions. Bring whatever you have, the deed, any old drawing of the house, photographs of the neighbours' walls, and get in touch so we can tell you what is genuinely buildable there and in what order the work would happen.
