Colonial Bungalows of India: Verandahs, High Ceilings and Lime

Almost every Indian city has them: a single-storey house set back in a large compound, under a big tiled or flat roof, wrapped in a deep verandah with columns and arches, its rooms so tall that the ceiling fans hang on long rods. Some are government residences and club houses, some are railway officers' quarters, many are family homes now hemmed in by apartment towers. They are usually called colonial bungalows, and they are some of the most comfortable buildings ever built for the Indian climate — in their time, without electricity at all.

They are also among the most misunderstood. Owners who inherit one often treat it the way they would treat a 1990s house: cement plaster over cracked walls, acrylic paint, a new concrete slab over a leaking roof, wiring chased into old brick, verandahs enclosed to gain a room. The building responds badly. Walls that were dry for a century start to show damp and salt, plaster blows off, roofs crack under new weight, and the house that kept cool begins to need air-conditioning in every room.

This article explains where the bungalow came from, how its verandahs, high ceilings and lime walls actually worked, how the main roof and wall systems are built, and how to repair them properly. It ends with what a new home — a bungalow on a 40 × 60 ft plot or even a flat — can borrow from the type. The aim is not nostalgia; it is to understand a building that solved heat, glare and rain with geometry and materials, and to use that knowledge honestly.

Where the bungalow came from

The word bungalow comes from bangla — 'of Bengal' — the name for a type of single-storey rural house of the Bengal region, with a thatched roof sweeping down over a raised floor. Officials and traders of the East India Company, living in Bengal and later across India, adapted this house for their own use, and the name travelled with the building. What they kept was the logic of the rural house: a raised floor to stay above the wet ground, a big roof to throw off rain and sun, and a covered space around the rooms where much of daily life could happen in the shade.

Through the nineteenth century the bungalow became the standard house of British India's official and military life. It was built in the cantonments, where army officers lived; in the civil lines, the planned areas laid out for administrators outside the old cities; along the railway lines, as housing for railway staff; and on the roads between towns as dak bungalows — rest houses on the postal (dak) routes where travelling officials could stay the night. The Public Works Department, set up in the mid-nineteenth century, produced standard plans for official residences, and these type plans spread the same room sizes, ceiling heights and verandah depths across very different climates.

Indian owners took up the type in turn. By the early twentieth century, bungalows were being built by lawyers, doctors, merchants and landowners, often mixing the colonial plan with local details — carved timber brackets, jaalis, courtyards, Indian tiles and painted ceilings. In the 1920s and 1930s, the new capital at New Delhi was laid out with large bungalows for officials; the area now known as the Lutyens' Bungalow Zone remains one of the best-known groups of the type. After Independence, the bungalow continued as the model for government housing and for the independent family house, and its descendants — the plotted bungalow, the row house, the farmhouse — still dominate Indian suburbs.

The plan: rooms inside a ring of shade

A classic bungalow plan is simple. A large central hall — often the drawing and dining room — runs through the middle of the house, with bedrooms and dressing rooms on either side. Each bedroom usually had its own bathroom, reached through a dressing room and often provided with a separate door to the outside so that it could be serviced without entering the house. Around this core runs the verandah, on all four sides in the most generous examples, on the front and the two hottest sides in smaller ones. The kitchen — usually called the cookhouse — was kept in a separate block at the rear, linked by a covered passage, to keep heat, smoke and the risk of fire away from the main house. Servants' quarters, stables and stores stood further back in the compound, and a porch at the front, wide enough for a carriage and later a car, sheltered arrival.

The plan is built around cross-ventilation. Rooms are one room deep from verandah to hall, or from verandah to verandah, so that air can pass straight through. Doors are tall and placed opposite one another; many rooms have doors on three sides. The plan is not compact — a bungalow uses far more roof and wall per square metre of room than a modern house — but every room is shaded, ventilated and daylit from more than one direction.

The section: how a bungalow stays cool

The real genius of the bungalow is in its section. Five elements work together. First, the raised plinth, commonly 600–1200 mm above ground, lifts the floor above monsoon water and damp, and lets the verandah catch more breeze. Second, the verandah — usually 2.4–3.6 m deep — shades the outer walls and doors through most of the day, so that the walls of the rooms themselves stay close to air temperature rather than baking in the sun. Third, the rooms are very tall: ceilings of around 4–6 m are common in plains bungalows. Hot air rises and collects under the ceiling, well above the heads of the people in the room. Fourth, ventilators — small openings high in the walls just below the ceiling, often with louvres or a pivoting glazed shutter — let that hot air escape, drawing cooler air in through the doors. Fifth, the large roof, whether tiled and pitched or flat with thick lime terracing, keeps direct sun off the rooms and, in the case of pitched roofs, creates a ventilated air space above the ceiling.

Before electricity, these were helped by two well-known devices. The punkah was a large cloth fan hung from the ceiling and pulled back and forth on a rope by an attendant, the punkah-wallah, often from the verandah. Khus tatties — screens woven from the fragrant roots of vetiver grass — were hung in doorways and windows on the windward side and kept wet, so that hot, dry summer winds were cooled by evaporation as they passed through. Both make it clear that the bungalow was designed for movement of air: the house was a machine for shade and breeze, and its people adjusted shutters, chiks and tatties through the day.

Lime: the material that holds it together

Most colonial bungalows are built in brick or stone laid in lime mortar and finished with lime plaster. Lime is made by burning limestone — calcium carbonate — in a kiln to produce quicklime (calcium oxide). Quicklime is then slaked with water to make hydrated lime (calcium hydroxide), which is mixed with sand and water to make mortar or plaster. Once on the wall, the lime slowly absorbs carbon dioxide from the air and turns back into calcium carbonate — in effect, back into a kind of limestone. This is the lime cycle, and it explains both the strengths and the demands of the material. Indian builders often added surkhi — finely ground burnt brick or clay — to lime mortar; it reacts with the lime and gives a stronger mortar that sets better in damp conditions. Many regional recipes also added organic materials such as jaggery or plant extracts, which traditional craftsmen used to improve workability and setting.

Lime has three properties that matter for an old building. It is softer and more flexible than cement, so a lime-built wall can accommodate small movements without cracking badly. It is vapour-permeable: moisture that gets into a thick wall from the ground or from rain can evaporate out through the lime plaster. And it is sacrificial: when salts or damp attack a wall, lime plaster and mortar decay first, protecting the brick and stone, and can be renewed. Cement does the opposite on all three counts. It is harder than old brick, so stresses concentrate in the brick; it is much less permeable, so moisture trapped behind cement plaster moves sideways and upwards and pushes salts out through the brick; and it is not sacrificial, so the brick decays instead of the plaster. This is why cement plaster on a lime wall so often leads, within a few years, to damp patches, flaking paint and crumbling brick.

Roofs: Mangalore tiles, Madras terrace and jack arches

Bungalow roofs fall into two broad families. Pitched roofs were originally thatched, later covered with country tiles and, from the second half of the nineteenth century, with Mangalore tiles — interlocking, machine-pressed clay tiles first produced at Mangalore by the Basel Mission and later by many factories along the west coast. A tiled roof is light, sheds monsoon rain quickly and leaves a ventilated space under the tiles, often above a timber or later a false ceiling. The trade-offs are maintenance — broken tiles, rotted battens, termite in rafters — and dust and birds entering the roof space.

Flat roofs were built in two main ways. The Madras terrace roof, common across south India and widely used elsewhere, uses timber joists — often teak — spanning between walls, with specially made terrace bricks laid diagonally on edge between them, bedded in lime mortar, and covered with a thick layer of lime concrete that is beaten and finished to shed water. The jack-arch roof, used widely in north and west India in the late nineteenth and early twentieth centuries, spans shallow segmental brick arches between rolled steel joists, with lime concrete filling the haunches to give a flat top. Both are heavy and well insulated, and both depend on the lime terracing on top staying intact. Their typical failures are rot in timber joists and rust in steel joists where water has penetrated, followed by cracks in the arches or bricks.

Regional variations

The bungalow was a type, not a single design, and it changed with climate and local building culture. The plains bungalow of north and central India is the archetype: tall rooms, a wraparound verandah, heavy walls, and either a tiled roof or a lime-terraced flat roof. In the hill stations of the Himalaya and the Nilgiris, bungalows were built for cold and rain rather than heat: lower rooms, fireplaces and chimneys, steep roofs of tile or later corrugated metal, timber floors and glazed verandahs that worked as sun rooms. Along the coasts, deep eaves and large tiled roofs dealt with heavy monsoon rain. In Bangalore, bungalows in the old cantonment are known for their decorative timber fretwork along eaves and verandahs. In New Delhi, the large official bungalows of the 1920s and 1930s combined classical columns and porches with deep shade, large plots and generous gardens.

Restoring a colonial bungalow today

Restoration begins with understanding, not demolition. The first step is a condition survey by an architect or conservation specialist working with a structural engineer: measured drawings, photographs, a record of cracks, damp and decay, and an investigation of the roof structure. Damp is the usual root problem, and its source decides the fix — rising damp from the ground, rain through a failed roof or blocked gutter, or leaks from plumbing added in later decades. Many 'structural' problems in old bungalows turn out to be water problems: a rotted joist end under a blocked rainwater outlet, a cracked arch over a rusted steel joist, a wall eroded at its base by a cement plinth protection that traps water against it.

The principles of good repair are well established in conservation practice in India, including the INTACH charter for unprotected architectural heritage: repair rather than replace, use compatible materials, do as little as necessary, and keep a record. In practice this means removing cement plaster from lime walls where it is causing damage and re-plastering in lime; repointing in lime mortar; repairing timber joists by splicing or replacing only decayed sections; renewing lime terracing rather than adding a concrete slab; and finishing walls in limewash or mineral paint rather than acrylic emulsion. Services should be added without cutting deep chases into old walls — surface conduits in neat runs, wiring through floor voids, plumbing grouped in new service zones. Where the bungalow is listed under a city's heritage regulations, alterations may need permission from the local heritage conservation committee, so the owner should check its status before work begins.

What a new home can borrow

Very few families today will build a 21-metre bungalow with a wraparound verandah, and copying colonial columns and arches on a modern house usually produces a costume rather than a building. But the ideas behind the bungalow are just as useful on a 40 × 60 ft plot, and several work even in a flat. A verandah or deep balcony of 2400–3000 mm on the south or west shades walls and glass and gives the family an outdoor room. A floor-to-floor height of 3300–3600 mm in a bungalow, or one double-height living space with openable high windows, lets hot air rise and leave. Doors and windows aligned across rooms give cross-ventilation. Transoms or ventilators above doors keep air moving when doors are shut for privacy. A raised plinth keeps floors dry on low plots. And lime plaster or limewash inside — on a pooja room, a foyer or a bedroom wall — brings the soft texture and breathability of the old walls into a modern interior.

The deeper lesson is about sequence. The bungalow's builders shaded first, ventilated second and only then thought about decoration. Modern houses often reverse this: large glass facades without shade, sealed rooms, and air-conditioning to make the result livable. Borrowing the bungalow's order of priorities is worth more than borrowing any of its details.

Where the bungalow goes next

The surviving colonial bungalows face two futures. In many cities they are being demolished for apartments because the land beneath them is worth far more than the building. At the same time, a growing number are being restored and reused — as homes, boutique hotels, cafés, studios and offices — because their tall rooms, verandahs and gardens offer something new buildings rarely can. Heritage listings, conservation architects and lime craftsmen are more available than they were a generation ago, and climate concerns are making the bungalow's passive cooling relevant again. The most likely future is a mixed one: fewer bungalows, better cared for, and their principles quietly absorbed into new climate-responsive houses.

Rules for living with, or learning from, a colonial bungalow

• Survey before you touch anything: measured drawings, a damp survey and a structural engineer's report on the roof.
• Find and fix the source of water first — roof, gutters, plinth, plumbing — before repairing any plaster.
• Repair lime walls with lime mortar, lime plaster and limewash or mineral paint; never with cement plaster or acrylic paint.
• Do not add a concrete slab or heavy screed on an old roof without a structural engineer's written approval.
• Keep the south and west verandahs open; add space in a new wing rather than enclosing them.
• Run new wiring and plumbing on surfaces or through voids; avoid deep chases in old walls.
• Check heritage listing status before alterations, and keep a photographic record of all work.
• In a new house, borrow the logic — shade, height, cross-ventilation, breathing finishes — not the costume.

Frequently asked questions

Why do colonial bungalows have such high ceilings?

Because hot air rises. Ceilings of around 4–6 m let warm air collect well above head height, and ventilators near the ceiling let it escape, drawing cooler air in through tall doors and windows. In the days before electric fans, the height also gave room for a punkah to swing.

What is the purpose of a verandah?

A verandah shades the outer walls, doors and windows of the rooms behind it, keeps rain off them, and provides a cool, covered outdoor room. In colonial bungalows it was usually 2.4–3.6 m deep, deep enough to block most direct sun from reaching the inner walls.

Can I use cement plaster on an old lime wall?

It is best avoided. Cement plaster is harder and much less permeable than lime, so it traps moisture in the wall, pushes salts into the brick and often leads to damp patches and crumbling brick within a few years. Repair lime walls with lime mortar and lime plaster, and finish them with limewash or mineral paint.

What is a Madras terrace roof?

A traditional flat roof in which timber joists span between walls, terrace bricks are laid diagonally on edge between the joists in lime mortar, and a thick layer of beaten lime concrete is laid on top to shed water. It is heavy and well insulated; its weak point is water reaching the timber joists through cracked terracing.

Is it worth restoring an old colonial bungalow?

Often, yes — if the structure is sound and the owner is willing to repair with compatible materials. Restored bungalows offer tall, naturally ventilated rooms and gardens that new buildings rarely match. A condition survey by a conservation architect and a structural engineer is the right first step before any decision.
