Balcony Designs
A balcony is the only part of an apartment that is genuinely outdoors, and it is almost always the most wasted. In most flats it holds a drying rack, two dead plants and the outdoor unit of an air conditioner.
The reason is rarely size. It is that balconies get treated as leftover space rather than as a room with a floor, a ceiling, a light and somewhere to sit. Once you design one properly, a two-metre balcony becomes the most used seat in the house.
This page covers flooring that survives sun and rain, railing requirements, the drainage detail that decides everything, planting that actually lives in Indian conditions, and what a balcony costs to do.
Flooring, and the fall that has to come first
Before any finish is chosen, confirm the slab has a fall towards the drain – usually 1 in 100, so about 10mm per metre – and that the finished balcony floor will sit at least 25mm below the internal floor level. Get this wrong and monsoon rain runs into the living room, which is the single most common balcony failure.
- Anti-skid vitrified tile – the practical default, rated R10 or better for wet grip
- Full-body porcelain – holds colour under UV, the best long-term appearance
- WPC deck tiles – clip over an existing floor, liftable, no wet work needed
- Teak or ipe decking – the warmest underfoot, needs oiling every year
- Terracotta – traditional, cool underfoot, porous and best sealed
Deck tiles in composite WPC are the popular retrofit because they clip over the existing floor without wet work and can be lifted for cleaning. Real teak decking is beautiful and needs annual oiling. Anti-skid vitrified tiles are the most practical, and full-body porcelain in a stone finish is the specification that looks good longest under direct sun.
Railings, safety and what the building will allow
Railing height should be at least 1,050mm from the finished floor, and higher where the balcony is above the fourth floor or where children use it. Any gap between balusters needs to be under 100mm so a child's head cannot pass through, which is the rule that catches most decorative horizontal designs.
Horizontal railings are also climbable, which is worth thinking about with young children regardless of the gap. Check the society bye-laws before designing anything: most apartment associations restrict changes to the external appearance of a railing, and glass infills or a raised screen frequently need written permission.
Making it usable, which means shade and seating
The reason balconies go unused in India is heat. A west-facing balcony is unusable from two until six for most of the year unless something shades it. A retractable awning, an outdoor bamboo or reed blind, or a pergola with a climbing plant changes the usable hours more than any furniture choice.
Seating needs to be small. Two chairs 600mm wide and a 450mm side table fit a 1.5m deep balcony; anything larger and the space stops working as circulation. Built-in bench seating along one end with storage underneath is usually the most efficient answer, and it hides the things balconies inevitably accumulate.
Planting that survives an Indian balcony
Match the plant to the aspect honestly. A south or west balcony gets brutal direct sun and suits bougainvillea, adenium, succulents and curry leaf. A north or east balcony is gentler and suits money plant, syngonium, ferns and most herbs. Putting a shade-loving plant on a west balcony is why balcony plants die.
Weight and drainage are the practical constraints. Wet soil in large planters is heavy, so keep big pots near the structural edge rather than mid-span, and never let a planter sit directly on the floor blocking the drain – raise it on feet so water can pass under and the tile below can dry.
The air conditioner unit, and other things to hide
Almost every Indian balcony hosts a condenser unit. It needs 300mm of clearance at the back and 500mm in front to breathe, and boxing it in tightly will raise your electricity bill and shorten the unit's life. A louvred screen with genuine airflow is the right answer, not a solid box.
The drying rack is the other constant. A ceiling-mounted pulley rack that lifts out of sight, or a wall-mounted folding rail that disappears when not in use, keeps the balcony a balcony for the six days a week it is not laundry day.
Specification
How we build a balcony
The fall and the level difference at the door are the two lines that prevent water in the living room.
| Specification | What we build |
|---|---|
| Floor fall | 1 in 100 towards the drain, confirmed before finishing |
| Level difference at door | Finished balcony floor 25mm below internal floor |
| Waterproofing | Membrane turned up 150mm at all walls before tiling |
| Tile grip rating | R10 or better for wet slip resistance |
| Railing height | 1,050mm minimum from finished floor |
| Baluster gap | Under 100mm, vertical rather than horizontal where children use it |
| Drain | Trapped outlet, never obstructed by a planter |
| AC condenser clearance | 300mm behind, 500mm in front, louvred screen only |
| Lighting | IP65 rated minimum, 2700K, on its own switch |
| Power | One weatherproof socket, RCD protected |
Budget
What a balcony costs
| Scope | Indicative range | What moves the number |
|---|---|---|
| WPC deck tiles over existing floor | Rs 180 to Rs 400 per sq ft | Tile quality and edge trims |
| Anti-skid porcelain, laid | Rs 220 to Rs 500 per sq ft | Tile grade and waterproofing |
| Teak or ipe decking | Rs 800 to Rs 1,800 per sq ft | Species and substructure |
| Built-in seating and screening | Rs 45,000 to Rs 2 lakh | Length, material and storage |
Indicative ranges. If the existing waterproofing has failed, add the cost of stripping back to the slab and re-laying a membrane, which is the item that most often turns a small balcony job into a large one.
Detailing
Four balcony mistakes
Raising the floor above the internal level
Deck tiles laid over an existing floor can lift the balcony above the living room threshold. The first heavy monsoon then sends water inside, and the only fix is taking it all up again.
Boxing in the AC condenser
A unit in a sealed enclosure recirculates its own hot air, works harder, costs more to run and fails sooner. Louvres with real airflow, not a solid decorative box.
Planters sitting flat on the drain side
A pot placed on the floor blocks water from reaching the outlet and keeps the tile beneath permanently wet. Raise every planter on feet.
Horizontal railings with children
Even within the 100mm gap rule, horizontal rails form a ladder. Vertical balusters are the safer specification wherever young children have access.
Living with it
Keeping a balcony working
Clear the drain before every monsoon and again mid-season. Leaves, soil washed out of planters and general dust will block a balcony outlet within one season, and a blocked drain on a balcony with a shallow fall means water finding the door threshold instead.
Lift WPC deck tiles once a year and wash the floor underneath, because damp and organic matter collect in the gaps and will stain the slab. Oil teak decking annually before the monsoon rather than after it, and check railing fixings each year for corrosion at the base where water sits.
Questions
Balcony questions
What is the best flooring for an Indian balcony?
Anti-skid vitrified or full-body porcelain rated R10 or better is the practical answer – it takes UV, monsoon rain and daily washing without changing colour. WPC deck tiles are the best retrofit where you cannot do wet work, provided the finished level still sits below the internal floor. Teak looks best and asks for annual oiling.
Can I enclose my balcony with glass?
Physically yes, legally it depends. Most apartment associations restrict changes to the external elevation, and in many cities enclosing a balcony counts as adding covered area, which can affect approvals. Get written permission from the association before ordering anything, because glazing is expensive to remove.
How do I stop rainwater entering from the balcony?
Two things, both structural rather than decorative. The balcony floor must fall towards the drain at about 1 in 100, and the finished balcony level must sit at least 25mm below the internal floor. If either is wrong, no threshold seal or door will reliably keep water out during heavy monsoon rain.
Which plants survive on a hot balcony?
Match the plant to the aspect. West and south balconies take direct afternoon sun and suit bougainvillea, adenium, succulents, curry leaf and lemongrass. North and east balconies are gentler and support money plant, ferns, syngonium and most kitchen herbs. Most balcony plant deaths are a sun mismatch rather than neglect.
What railing height is required?
At least 1,050mm from the finished floor, with gaps under 100mm between balusters. Remember that adding decking raises the floor and therefore reduces the effective railing height, which is a detail that gets missed on retrofits and can take a compliant railing below the safe dimension.
