Standard flat sizes in Tricity (2026): room dimensions, carpet ratios and layouts for 1BHK, 2BHK and 3BHK
Real carpet area ranges and room-by-room dimensions for 1BHK, 2BHK and 3BHK flats across Mohali, Zirakpur, Chandigarh and Panchkula. Includes the legal minimum room size under the National Building Code.
Short answer: A standard 1BHK in Tricity runs 450–650 sq ft carpet (650–900 sq ft super area). A standard 2BHK runs 850–1,100 sq ft carpet (1,250–1,450 sq ft super area). A standard 3BHK runs 1,250–1,750 sq ft carpet (1,750–2,250 sq ft super area). For rooms: a comfortable master bedroom is 12×14 ft, a secondary bedroom is 10×12 ft, the living room is 12×14 to 14×16 ft, the kitchen is 8×10 ft, and an attached washroom is 5×8 ft. The National Building Code sets a legal floor — 9.5 sq m (about 102 sq ft) for the main habitable room — but no Tricity builder actually builds to that minimum.

Every second flat listing in Mohali or Zirakpur throws two numbers at you — carpet area and super area — and expects you to know which one to trust. Most buyers don't, and brokers rarely explain the gap unprompted. This is a plain reference: what a 1BHK, 2BHK and 3BHK actually measure in Tricity, room by room, and what "spacious" versus "cramped" looks like in real feet and inches. Hoomzz lists physically verified flats for sale and rent across Chandigarh, Mohali, Zirakpur, Panchkula and Kharar, and carpet area confusion is one of the most common reasons a buyer walks into a viewing disappointed.
Carpet, built-up and super area — the one distinction you need
Under Section 2(k) of the Real Estate (Regulation and Development) Act, 2016, carpet area is the net usable floor area inside your walls — the space you can actually put furniture on. RERA requires developers to quote and sell on carpet area, not on inflated super area figures. Built-up area adds the thickness of your own walls and balconies. Super built-up area (also called saleable area) adds a share of the lobby, stairwell, lift shaft and clubhouse — space you'll walk through but never own outright. In most Tricity high-rises this loading runs 20–40% over carpet area, and it tends to sit higher in newer gated societies with more shared amenities than in older builder floors. If a listing only states one number, ask which one it is before you compare prices per square foot — a flat quoted on super area will look artificially large next to one quoted on carpet. Hoomzz's carpet area vs super area RERA loading guide walks through the maths in more detail if you want to check a specific quote.
1BHK: carpet area and room-by-room layout
A standard 1BHK in Mohali, Zirakpur or Kharar carries a carpet area of 450–650 sq ft, translating to roughly 650–900 sq ft of super area depending on the society's loading. This is the size bracket that dominates listings near VIP Road Zirakpur, Kharar's Phase 1 belt and the smaller GMADA pockets aimed at single tenants and young couples.
| Room | Typical size (ft) | Approx sq ft |
|---|---|---|
| Bedroom | 10 × 11 | 110 |
| Living/dining | 11 × 13 | 140–150 |
| Kitchen | 7 × 9 | 60–65 |
| Bathroom | 5 × 7 | 35 |
| Balcony | 4 × 8 | 30–32 |
A 1BHK below roughly 450 sq ft carpet usually means a compact bedroom under 100 sq ft and a kitchen too narrow for a second person to stand comfortably — workable for a single tenant, tight for a couple who both cook.
2BHK: the size everyone benchmarks against
The 2BHK is Tricity's most-searched configuration, and for good reason — it's the default for a young family, a couple starting out, or two working professionals sharing. A standard 2BHK carries a carpet area of 850–1,100 sq ft, with super area landing around 1,250–1,450 sq ft once loading is applied. In Mohali's IT City and Aerocity belt, and in Zirakpur's newer high-rises, this bracket is the most heavily built segment on the market.
| Room | Typical size (ft) | Approx sq ft |
|---|---|---|
| Master bedroom | 12 × 14 | 168 |
| Second bedroom | 10 × 12 | 120 |
| Living/dining | 13 × 15 | 190–200 |
| Kitchen | 8 × 10 | 80 |
| Attached washroom | 5 × 8 | 40 |
| Common washroom | 5 × 7 | 35 |
Master bedroom size with an attached washroom is where buyers most often get caught out on a floor plan. A genuinely comfortable master — big enough for a king bed, two wardrobes and walking space — needs at least 12×14 ft of room area plus a separate 5×8 ft washroom carved out of that footprint, not included in it. Some builders quote the bedroom size inclusive of the attached bathroom to make the number look bigger; always ask whether the figure on the brochure is the bedroom alone.
If a "2BHK" is quoted below 800 sq ft carpet area, check the second bedroom dimensions before you commit — it's very often under 90 sq ft, which fits a single bed and little else. That's a 1.5BHK wearing a 2BHK price tag.
3BHK: family-size layouts and where they cluster
A standard 3BHK runs 1,250–1,750 sq ft carpet, or roughly 1,750–2,250 sq ft super area. This is the bracket aimed at families of four or more, and it's where you start seeing a genuine study or utility room in the layout rather than a converted balcony. GMADA sectors, New Chandigarh and Panchkula's established sectors carry more 3BHK stock than Zirakpur, where 2BHKs still dominate new launches.
| Room | Typical size (ft) | Approx sq ft |
|---|---|---|
| Master bedroom | 13 × 15 | 195 |
| Second bedroom | 11 × 13 | 140–145 |
| Third bedroom / study | 10 × 11 | 110 |
| Living/dining | 15 × 18 | 270 |
| Kitchen | 9 × 11 | 100 |
| Attached washroom (master) | 6 × 8 | 48 |
A luxury 3BHK in a premium Mohali or Zirakpur society can push super area to 2,400–2,600 sq ft with a servant room, separate utility balcony and a larger master suite — but that's the top of the bracket, not the standard.
A 3BHK works if
- You're a family of four or more and need separated bedrooms, not just extra rooms
- You work from home and need a dedicated study that isn't a dining table
- You expect parents or in-laws to stay for extended periods
Look at a 2BHK instead if
- It's just the two of you — a spare 3BHK bedroom is dead space you're still paying maintenance on
- Budget is tight; a 3BHK's per-sq-ft rate rarely drops enough to offset the extra 400–500 sq ft
- You need central Mohali or Zirakpur location over floor area — 3BHKs push you further out for the same budget
What the legal minimum actually is
The National Building Code of India sets a floor, not a target. Under NBC 2016, a dwelling unit's main habitable room must have a minimum floor area of 9.5 sq m (about 102 sq ft) with a minimum width of 2.4 m (about 8 ft), and a second habitable room can drop to 7.5 sq m. Minimum ceiling height for human habitation is 2.75 m. In practice, no reputable Tricity builder constructs to this floor — it exists to stop truly unlivable subdivisions, not to describe what you should accept. If a room in a resale flat measures close to the NBC minimum, treat it as a warning sign on layout quality, not a compliance tick.
Builder floors versus society flats: does square footage differ?
Yes, usually. An independent builder floor in Zirakpur or Kharar tends to carry a higher carpet-to-super ratio than an apartment in a large gated society, because there's no shared lobby, lift bank or clubhouse eating into the loading. A builder floor quoted at 1,400 sq ft super area might deliver 1,150–1,250 sq ft carpet — a loading of roughly 12–20% versus the 20–40% typical of high-rise societies. The trade-off is that you lose the lift, security desk, and amenities that a gated society bundles in. Hoomzz's guide to gated society benefits and their real monthly cost covers that trade-off if you're weighing the two formats.
How much space does a family of four actually need?
As a working rule, a family of four is comfortable in a 2BHK with at least 950–1,000 sq ft carpet area, or a compact 3BHK starting around 1,250 sq ft carpet if the children need separate rooms as they grow. Below that, a 2BHK still functions but storage and study space get squeezed — expect to lose a wall to a wardrobe-cum-study setup in the second bedroom. Space needs also scale with how much time the household spends indoors; a family with a work-from-home parent needs the extra 100–150 sq ft more than one that's out all day.
Tricity's local real estate Instagram pages and creators are also a genuine source renters and buyers use to sense-check layouts and area vibes before a site visit — useful for a first impression, though it's not a substitute for measuring the flat yourself.
Frequently asked questions
What is the average carpet area of a 2BHK flat in Mohali and Zirakpur?
A standard 2BHK in Mohali or Zirakpur carries a carpet area of roughly 850–1,100 sq ft, translating to about 1,250–1,450 sq ft of super area once loading is applied. Newer high-rise societies in Zirakpur's VIP Road corridor tend to sit at the higher end of this range, while older Mohali sector construction can run slightly tighter.
What is considered a spacious room size for a 3BHK master bedroom?
A spacious 3BHK master bedroom in Tricity measures at least 13×15 ft (about 195 sq ft), large enough for a king bed, two wardrobes and a small seating area, with a separate 6×8 ft attached washroom. Anything under 12×12 ft in a 3BHK master is on the smaller side for the configuration.
What is the standard super area for a luxury 3BHK apartment in Tricity?
A luxury 3BHK in a premium Mohali or Zirakpur society typically runs 2,000–2,600 sq ft of super built-up area, against a standard 3BHK's 1,750–2,250 sq ft. The extra space usually goes into a bigger master suite, a utility or servant room, and wider balconies rather than a fourth bedroom.
How much square footage is ideal for a family of four?
A family of four is comfortable in a 2BHK with 950–1,000 sq ft carpet area or more, or a 3BHK starting around 1,250 sq ft carpet once children need separate rooms. Households with a work-from-home member should budget an extra 100–150 sq ft for a dedicated study corner.
Are builder floors larger in square footage than society flats?
Builder floors aren't necessarily larger in total super area, but they usually deliver more carpet area for the same super area quoted, because there's no shared lobby, lift or clubhouse loading. A builder floor's loading typically runs 12–20% over carpet, against 20–40% in a large gated society.
What is the standard carpet area for a 1BHK in Tricity?
A standard 1BHK carries a carpet area of 450–650 sq ft, with super area landing around 650–900 sq ft depending on the society. Below roughly 450 sq ft carpet, expect a genuinely tight bedroom and a kitchen too narrow for two people to work in comfortably.

Sources, and what here is judgement rather than data
The carpet area definition under Section 2(k) of RERA, and the rule that developers must quote and sell on carpet area, is confirmed by TaxGuru's explainer on the RERA carpet area definition. The National Building Code's minimum habitable room area (9.5 sq m) and minimum room width (2.4 m) are set by the Bureau of Indian Standards; see the BIS National Building Code of India 2016 page. Punjab's affordable housing policy flat-size cap is reported by The Tribune's coverage of Punjab's affordable housing policy.
Everything else — the specific room-by-room dimension tables, the loading percentage ranges for builder floors versus societies, the "1.5BHK wearing a 2BHK price tag" framing, and the family-of-four space rule — is editorial judgement built from typical Tricity floor plans and general Indian residential space-planning norms, not a single measured dataset. Treat the room dimensions as a reasonable planning reference, and always verify against the actual floor plan of any flat you're shortlisting.
