Paying-guest accommodation and private hostels have become a large part of how Indian cities house students and young professionals. Around colleges, coaching hubs, IT parks and hospitals, bungalows are converted into PGs, apartment floors are let bed by bed, and purpose-built hostels and co-living buildings rise on commercial plots. For an owner, the logic is simple: a building let by the bed earns more than the same building let by the flat. For residents, the PG or hostel is often their first home away from family, and the quality of that home shapes their health, their studies and their safety.
The design of these buildings is frequently an afterthought. Rooms are filled with as many beds as the floor will hold, cross-ventilation is lost to partitions, toilets are too few, electrical loads are carried on extension boards, and windows are fitted with fixed grills while the only staircase doubles as a store. Fire incidents in crowded commercial and residential buildings in India have repeatedly shown how quickly smoke fills a single escape route. Good hostel design is not about luxury; it is about getting the space per person, the air, the toilets, the escape routes and the electrical system right — and then making the rooms pleasant enough that residents stay.
This article sets out practical planning dimensions for rooms, bunks, toilets and common areas, explains fire and life-safety principles in general terms, lists the approvals that commonly apply, and prices a typical room fit-out. Fire safety, building use and licensing rules vary by state and city and change over time; the guidance here is general information, not legal or fire-engineering advice, and every project should be checked with the local authority, a licensed fire consultant and a structural engineer where walls or loads change.
PG, hostel and co-living: what each one is
The words are used loosely, but the differences matter, because the type of use affects which rules apply. A paying-guest (PG) arrangement traditionally meant a family letting a room in its own home; today it usually means a house or flat run as shared accommodation, often with meals. A hostel is a building, or part of one, designed or used mainly for residents in rooms and dormitories, attached to an institution or run privately. Co-living describes organised operators who offer furnished private or shared rooms with common lounges, kitchens and services, usually on monthly contracts. Under the National Building Code of India 2016, Part 4, buildings used for sleeping accommodation fall in the residential occupancy group, with sub-divisions that include lodging or rooming houses and dormitories; which sub-division a given building falls into is decided by the authority, and it affects the fire-safety provisions required.
| Type | Typical building | Typical residents | Food | Room types | What to confirm early |
|---|---|---|---|---|---|
| PG in a family home | Bungalow or flat, owner living in | Students, working singles | Home meals, often | Single or twin | Society or local rules on letting rooms; resident registration |
| Run PG (owner not resident) | Converted bungalow or flats | Students, young professionals | Mess or tiffin | Twin, triple, some single | Permitted use of the building, fire safety, food registration if meals |
| Private hostel | Purpose-built or converted building | Students near colleges or coaching | Mess | Twin to dormitory | Building plan for hostel use, fire NOC as applicable |
| Institutional hostel | On campus | Enrolled students | Mess | Single to dormitory | Institution's own standards plus NBC |
| Co-living | Purpose-built or refurbished block | Working professionals | Self-cook or café | Single and twin with en-suite | Commercial or residential use permission, fire safety |
| Working women's or men's hostel | Purpose-built or converted | Working adults | Mess | Twin and triple | Any state-specific rules for such hostels; security provisions |
From dharamshala to co-living: a short background
India has a long tradition of shared lodging. Dharamshalas and sarais along pilgrimage and trade routes offered travellers a room or a sleeping platform around a courtyard, with a well and a shared kitchen — a plan form that kept air moving and gave everyone a short route to the open. Colonial-era colleges and universities brought the residential hostel with long corridors of single and double rooms, common washrooms at the ends of wings and a dining hall, a model that most Indian campuses still follow. The paying-guest arrangement grew with migration to cities, first in family homes and then as a business. In the last decade, organised co-living operators have introduced design standards, app-based services and branded interiors to what was once an informal market. The design challenge has stayed the same throughout: many people sleeping under one roof need light, air, privacy, sanitation and a safe way out.
Room sizes and furniture per resident
Space per resident is the first decision and the one most often abused. The National Building Code of India 2016, Part 3, sets minimum sizes for habitable rooms — for example a minimum area of 9.5 m² with a minimum width of 2.4 m for a single habitable room, and a minimum clear height of 2.75 m — and local bylaws may set their own figures; these minimums describe a room, not how many people may sleep in it. For planning shared rooms, a practical guide used in hostel design is to provide about 6–8 m² of room area per resident in twin and triple rooms, and to ensure each resident has a bed, a desk, a chair, lockable storage and a clear walking space. Dormitories with bunks can go denser, but only with careful ventilation, escape and supervision.
| Room type | Typical internal size | Area per resident | Furniture per resident | Notes |
|---|---|---|---|---|
| Single | 2700 × 3600 to 3000 × 3900 mm (≈ 9.7–11.7 m²) | ≈ 9.7–11.7 m² | Bed 900 × 1950, desk 1000 × 550, chair, wardrobe 900 wide | Meets the NBC minimum for a habitable room; local rules apply |
| Twin-share | 3600 × 4200 mm (≈ 15.1 m², 163 sq ft) | ≈ 7.6 m² | As single, mirrored on two walls | The most common PG room; reference room in Fig. 1 |
| Triple-share | 3900 × 5100 mm (≈ 19.9 m²) | ≈ 6.6 m² | As single; one bed may be along the window wall | Check daylight and cross-ventilation |
| Four-bed dormitory with two bunks | 3600 × 4200 mm (≈ 15.1 m²) | ≈ 3.8 m² | Bunk pair, one desk each where possible, lockers | Only with excellent ventilation and escape |
| Six- to eight-bed dormitory | 4800 × 6000 mm (≈ 28.8 m²) | ≈ 3.6–4.8 m² | Bunks, lockers, shared desks | Short-stay hostels; supervision essential |
| Attached toilet (where provided) | 1200 × 1800 to 1500 × 2100 mm | — | WC, shower, basin, exhaust | Wet-dry separation; anti-skid floor |
The twin-share room in Fig. 1 is the most common unit in Indian PGs, and its geometry is worth copying. The beds run head-to-window along the side walls, leaving an 1800 mm clear zone in the centre; desks sit beside the bed foot on each side so that each resident has a private corner; wardrobes stand at the door end, where they screen the beds from the corridor when the door is open. Every resident has an outside window within reach, and the door swings clear of all furniture. The same room with four beds in two bunks becomes a dormitory with under 4 m² per resident — possible, but only with very good ventilation and escape.
Bunk beds: dimensions and the ceiling-fan problem
Bunks double capacity, which is why they are popular, and they bring three specific risks: falls from the upper deck, heads striking the ceiling or a fan, and residents trapped in a crowded room. A safe bunk has a rigid frame fixed so it cannot rock, a guard rail on all sides of the upper deck except the ladder opening, a fixed ladder with flat treads, a stated maximum mattress thickness so the rail stays effective, and enough clear height above each mattress for a resident to sit up. The European bunk-bed standard EN 747 is a widely used reference for rail heights and gaps; Indian buyers can ask manufacturers whether their bunks are tested to it or to an equivalent. Upper bunks are generally not suitable for young children.
The fan problem deserves emphasis because it is a real hazard in Indian rooms. A resident sitting up on an upper bunk has their head roughly 2.5 m above the floor — the same height as the blades of a typical ceiling fan. Bunks must never be placed under a ceiling fan's blade circle. Use wall-mounted fans, air-conditioning or a fan positioned well away from the bunks, and check this at every room layout change.
Toilets, showers and water
Sanitation is where shared accommodation most often falls short. The National Building Code of India 2016, Part 9 (Plumbing Services), tabulates the number of water closets, urinals, basins and baths for different occupancies, and local rules may add to it; designers should work from those tables. Operators commonly plan more generously than the minimum because morning peaks — everyone leaving for college or work within the same hour — decide how residents experience the building. Part 9 also gives per-capita water demand; for hostels it is of the order of 135 litres per head per day, which sets the size of overhead and underground storage and pumps.
| Item | Planning guide (confirm with NBC Part 9 and local rules) | Design note |
|---|---|---|
| Shared WC and shower blocks | Many operators aim for about one WC and one shower per 6–8 residents | Separate blocks by gender where both are housed |
| Basins | Rows of basins outside WCs reduce morning queues | Mirror and shelf at each basin |
| Attached toilets (premium rooms) | 1200 × 1800 to 1500 × 2100 mm | Wet-dry separation; exhaust fan to outside |
| Hot water | Central solar or heat-pump system with backup, or geysers per toilet | Geysers need their own circuits and RCD protection |
| Water storage | Size from per-capita demand × residents, plus fire reserve if required | Fire water reserve is decided by the fire authority |
| Floors and walls | Anti-skid tiles, full-height dado in showers | Waterproofing with a flood test before tiling |
| Laundry | Washing machines on a separate wet area with drains | Drying area with sun and air, or dryers |
Common areas that make a hostel work
Residents spend most waking hours outside their rooms, and common areas are where a hostel either becomes a community or a dormitory. The essentials are a dining area or mess, a study room or quiet zone, a laundry and drying area, a lounge or visitors' area, and a reception or warden point that controls the entrance. CCTV belongs at entrances, corridors and common areas — never in rooms, toilets or changing areas. In converted bungalows, the ground-floor living and dining rooms usually become the mess and lounge, and the original kitchen becomes the mess kitchen, which then needs proper ventilation, gas safety and a food-safety registration if meals are served.
| Space | Indicative size | What it needs | Common mistake |
|---|---|---|---|
| Entrance and reception or warden desk | 6–12 m² | View of the entrance, visitor register, key and parcel storage | No control point; anyone walks in |
| Mess or dining | ≈ 1.0–1.5 m² per seat; seats for a third to half of residents per sitting | Washable floor, hand-wash basins, good exhaust | Dining in the corridor |
| Mess kitchen | Sized to meals served; specialist layout | Gas bank outside, exhaust, separate wash area | LPG cylinders inside the kitchen or rooms |
| Study room | ≈ 1.5–2.0 m² per seat | Quiet, good daylight, sockets at each seat | No sockets; residents use extension boards |
| Laundry and drying | One machine per 15–25 residents is a practical start | Drain, water point, ventilation, drying space | Clothes dried in corridors and stairs |
| Lounge and visitors' area | 8–20 m² | Seating, daylight, visible from reception | Turned into extra bedrooms |
| Stores and housekeeping | 4–8 m² per floor | Shelving, lockable, away from escape routes | Mattresses stored under the staircase |
Fire and life safety: the principles
Fire safety in shared accommodation is not optional and not a matter of taste. The National Building Code of India 2016, Part 4 (Fire and Life Safety), sets out occupancy classification, means of escape, compartmentation, detection, fire-fighting provisions and limits on combustible interior finishes; states enforce it through their own fire-service laws and rules, which decide when a fire safety certificate or no-objection certificate is required — Gujarat, for example, through the Gujarat Fire Prevention and Life Safety Measures Act, 2013. Requirements depend on the building's height, area, occupancy and number of residents, so a licensed fire consultant and the local fire authority should confirm them for every project. The principles below are general and conservative.
- Every floor needs safe escape: where rules require two exits, provide them, remote from each other; never block, lock or store goods on stairs, corridors or exits.
- Doors on escape routes must open easily from inside without a key; padlocked grills on exits and fixed grills on every window are dangerous — confirm escape openings with the fire consultant.
- Install detection and alarms as required for the occupancy, and at minimum smoke alarms in corridors and rooms in small PGs, tested monthly.
- Provide portable extinguishers of the right type and number (IS 2190 covers selection and siting) near the kitchen and on every floor, with staff trained to use them.
- Light every escape route with emergency lighting and mark exits with illuminated signs.
- Use FR or FRLS cables (IS 694) in concealed conduits, correctly rated MCBs and RCCB protection; ban heaters, irons and cooking appliances in rooms unless circuits are designed for them.
- Keep LPG out of rooms; place gas banks outside the kitchen in a ventilated enclosure with a gas-safety installer's approval.
- Limit combustible finishes in corridors and stairs — no foam wall panels, carpets or decorative timber on escape routes; fire-retardant plywood (IS 5509) where boards are used.
- Display a floor plan with escape routes on every floor and run drills with residents at least once a term or season.
| Safety item | Purpose | Reference (general) | Who confirms |
|---|---|---|---|
| Means of escape — exits, stairs, corridors | Let everyone leave before smoke fills the route | NBC 2016 Part 4 | Architect, fire consultant, fire authority |
| Fire detection and alarm | Early warning, especially at night | NBC 2016 Part 4; IS 2189 | Fire consultant; licensed installer |
| Portable extinguishers | Tackle small fires early | IS 2190; IS 15683 | Supplier and fire consultant; refill schedule |
| Emergency lighting and exit signs | Visible routes during power failure | NBC 2016 Parts 4 and 8 | Electrical consultant |
| Wiring, MCBs, RCCBs, earthing | Prevent electrical fires and shock | IS 732; IS 694; IS 12640 | Licensed electrical contractor |
| Interior finishes on escape routes | Limit flame spread and smoke | NBC 2016 Part 4; IS 5509 for FR plywood | Designer with fire consultant |
| Kitchen gas installation | Prevent leaks and explosions | Gas supplier and installer requirements | Authorised gas installer |
| Fire safety certificate or NOC | Legal permission where required | State fire-service law and rules | Local fire authority |
Electrical, ventilation and comfort
Electrical overload is a common cause of fire in crowded accommodation, so the electrical design deserves the same care as the room layout. Give each room its own MCB and, where tariffs or billing require it, a sub-meter for air-conditioning; protect circuits with RCCBs; and provide enough sockets that nobody needs an extension board — typically two at each desk, one at each bed (with USB charging) and dedicated points for any AC and geyser. Wire with FR or FRLS cable in conduit, and keep the distribution boards in a lockable, ventilated cupboard outside rooms. In Surat and much of Gujarat, the heat and humidity of summer make cross-ventilation and ceiling insulation as important as air-conditioning: rooms with windows on two sides, or a window plus a high vent to the corridor, stay far more comfortable, and an exhaust fan in every toilet keeps damp out of the rooms.
The personal zone: one wall for each resident
In shared rooms, what makes residents feel at home is a personal zone they control: their own bed, a desk with a light and sockets, a shelf, a pin-up board and storage they can lock. Planning this zone on one wall per resident, as in Fig. 4, gives privacy without partitions and keeps the room easy to clean and inspect.
Materials that survive shared use
Hostel interiors take far more wear than homes: furniture is moved, walls are leaned on, mattresses are changed every few years and rooms are repainted between residents. Durable, repairable and fire-sensible materials save money over the life of the building. Rounded edges with 2 mm PVC edge-banding on all joinery, solid-core flush doors with door stops and closers on corridors, washable emulsion paint on walls, and matt vitrified tiles or welded vinyl on floors are sensible defaults. Indicative October 2026 prices from this site's guides: vitrified flooring about ₹85–160 per sq ft laid, sheet vinyl about ₹180–400 per sq ft laid, economy emulsion about ₹12–18 per sq ft and premium about ₹20–30, and budget-band joinery about ₹750–1,200 per sq ft of front.
| Element | Recommended | Avoid | Why |
|---|---|---|---|
| Floors in rooms | Matt vitrified tile or welded vinyl | Polished glossy tiles, carpets | Slip risk, cleaning, hygiene |
| Walls | Washable emulsion; a wipeable panel behind beds and desks | Wallpaper, foam panels | Scuffs and fire load |
| Joinery | BWR plywood or HDHMR carcass, laminate, 2 mm PVC edges | Particle board near toilets, sharp edges | Moisture and impact |
| Doors | Solid-core flush doors with stoppers; fire-rated where required | Hollow doors, glass panels at low level | Security, durability, fire |
| Mattresses | Washable, removable covers; replace on a schedule | Uncovered foam | Hygiene and fire load |
| Toilets | Anti-skid tiles, CP fittings with metal bodies, exhaust | Light plastic fittings | Heavy use |
| Lighting | LED ceiling lights plus a desk lamp per resident | Single dim tube per room | Study and safety |
What a PG or hostel room costs to fit out
Costs vary enormously with the starting building and the standard offered, so the most useful number is a line-item room. The example below fits out the twin-share room of Fig. 1 — 3600 × 4200 mm, about 163 sq ft — to a durable mid-range standard, assuming the walls, floor and services already exist. Paintable area is about 580 sq ft (walls and ceiling, less openings). Air-conditioning, new flooring and the attached toilet are excluded and listed separately because many operators reuse existing floors or provide shared toilets. Wardrobe joinery uses the budget band this site applies to wardrobes; furniture and electrical lines are indicative market ranges.
| Line (twin-share room, 163 sq ft) | Quantity | Indicative rate (October 2026) | Amount (₹) |
|---|---|---|---|
| Wardrobes, 2 × 900 × 2100 mm, laminate | ≈ 40.7 sq ft of front | ₹750–1,200 per sq ft (budget band) | 30,500–48,800 |
| Beds, single 900 × 1950 mm with storage | 2 | ₹10,000–25,000 each | 20,000–50,000 |
| Mattresses with washable covers | 2 | ₹5,000–12,000 each | 10,000–24,000 |
| Desk with shelf, and chair | 2 sets | ₹9,000–20,000 per set | 18,000–40,000 |
| Painting walls and ceiling | ≈ 580 sq ft | ₹12–18 per sq ft (economy emulsion) | 7,000–10,400 |
| Lights, fan, sockets, room MCB and sub-meter | 1 room | Lump sum | 12,000–25,000 |
| Curtains or blinds | 1 window | Lump sum | 4,000–10,000 |
| Total per room | 1,01,500–2,08,200 | ||
| Per bed | ≈ 50,750–1,04,100 |
For a 24-bed floor of twelve such rooms, the room fit-out alone is therefore about ₹12.2–25 lakh, before air-conditioning, toilets, corridors, common areas and fire-safety systems. If floors are replaced, add about ₹85–160 per sq ft for vitrified tile laid; if each room gets an attached toilet, price it as a small bathroom, which this site's renovation guides place at about ₹60,000 for a refresh to ₹1.2–1.8 lakh for a standard rebuild. Lockers in common areas run about ₹3,000–8,000 per compartment, and basic smoke alarms about ₹800–2,500 each with ABC extinguishers about ₹1,000–3,500 each, as this site's fire-safety guide notes — but detection and fire-fighting systems required for the building must be designed and priced by a fire consultant, not assembled from a shopping list.
Approvals and registrations: what commonly applies
The legal side of running a PG or hostel differs from state to state and city to city, and it changes. What follows is general information to help owners ask the right questions — not legal advice. The first question is whether the building may be used for this purpose at all: a residential flat in a housing society, a bungalow in a residential zone and a commercial plot are treated differently, and converting use may need permission. The building should have an approved plan and occupancy or completion certificate for its current use. Beyond that, the common touchpoints are the fire authority, the municipal corporation, the police, food-safety registration if meals are served, labour registrations if staff are employed, and tax.
| Approval or step | When it typically applies | Who to ask |
|---|---|---|
| Permitted use, change of use, building plan | Converting a home or building to PG or hostel use | Municipal corporation or development authority; architect |
| Fire safety certificate or NOC | Depending on height, area and occupancy under state rules | Local fire authority; licensed fire consultant |
| Housing society permission | PGs inside apartment buildings | Society managing committee; society bye-laws |
| Resident information or verification with police | Many cities require owners to share tenant or resident details | Local police station; city police website |
| Food business registration or licence (FSSAI) | When meals are prepared and served to residents | FSSAI registration portal |
| Shops and establishments registration | When the business employs staff, under state law | State labour department |
| Trade or health licence | Where the municipal corporation requires it for lodging businesses | Municipal corporation |
| GST and income tax | Depends on turnover, nature of service and structure | Chartered accountant |
Where hostel and PG design is heading
The market is moving from informal rooms to managed buildings. Organised co-living operators have shown that residents will pay for better design: smaller private rooms with good storage, en-suite or well-run shared bathrooms, generous lounges, reliable Wi-Fi, laundry and housekeeping. Purpose-built student housing is appearing near larger universities. Technology is changing operations — app-based rent and complaints, smart locks and card access, sub-metered electricity — and energy cost is pushing operators towards heat-pump water heating, solar panels and better-insulated roofs. Regulators in several cities have tightened enforcement on fire safety in crowded buildings after serious incidents, and that trend is likely to continue. For owners, the lesson is that a well-designed, compliant building is becoming the only kind that can be run for long without trouble.
In Aaditya Interior's commercial and hospitality work, the same principle that governs a hotel guest room applies to a hostel room: design for the person who will live there on an ordinary day, and for the night when something goes wrong. The two are not in conflict. A room with a clear centre, a window, a desk with sockets and a door that opens onto a clear corridor towards two exits is both a better place to live and a safer one.
Rules for designing a PG or hostel
- Confirm permitted use, occupancy classification and fire-safety requirements before buying furniture or partitioning rooms.
- Plan about 6–8 m² of room per resident in twin and triple rooms; go denser only with bunks, excellent ventilation and supervision.
- Give every resident a bed, a desk with light and sockets, and a lockable wardrobe on their own wall.
- Never place an upper bunk under a ceiling fan; fit guard rails, a fixed ladder and a marked maximum mattress thickness.
- Keep both escape routes and every corridor clear; no padlocks on exits and no storage on stairs.
- Design the electrical system so nobody needs an extension board: room MCBs, RCCBs, FRLS cables and enough sockets.
- Size toilets, showers and water storage from NBC Part 9 and the morning peak, not from the minimum.
- Choose washable, repairable materials and replace mattresses on a schedule.
Frequently asked questions
What is the minimum room size for a PG in India?
There is no single national PG room size. The National Building Code of India 2016, Part 3, sets minimum sizes for habitable rooms (for example 9.5 m² with a 2.4 m minimum width for a single habitable room) and local bylaws apply. For shared rooms, a practical planning guide is about 6–8 m² per resident, so a twin room of about 15 m² suits two people. Check local rules before letting.
How many beds can be put in a PG room?
It depends on the room size, ventilation, toilets and escape, and on any local rules. As a guide, a 3600 × 4200 mm room suits two residents comfortably, three with care, and four only as a bunked dormitory with very good ventilation. More beds without more toilets, air and exits is not a design decision; it is a risk.
Does a PG need a fire NOC?
It depends on the state's fire-service law and on the building's height, area and occupancy. Many smaller buildings may not need a formal certificate, while larger hostels and taller buildings commonly do. Either way, basic fire safety — clear exits, alarms, extinguishers, safe wiring and no LPG in rooms — should be in place. Ask the local fire authority or a licensed fire consultant.
How much does it cost to furnish a PG room?
For a twin-share room of about 163 sq ft with two wardrobes, beds, mattresses, desks and chairs, paint, lights and sockets, curtains and a room MCB, indicatively about ₹1.02–2.08 lakh in October 2026, or about ₹51,000–1.04 lakh per bed. Air-conditioning, new flooring, attached toilets and building fire systems are extra.
Are bunk beds safe in a hostel?
They can be, if they are rigid and fixed, have guard rails on all sides of the upper deck except the ladder, a fixed ladder, a marked maximum mattress thickness, enough headroom above each mattress, and no ceiling fan above. Buy from makers who can show testing to a recognised standard such as EN 747.
