30x40 House Plan | 3 Floor East Facing Design
East-facing G+2 on a 30×40 plot — three purposeful floors catching the morning sun
If you are planning a 30x40 house plan 3 floor east facing, you are looking at one of the most cost-efficient configurations in Indian residential construction. A 30×40 plot (1,200 sq ft) with G+2 construction delivers roughly 2,100–2,250 sq ft of built-up area. That is enough for 4–5 bedrooms, dedicated parking, a rental unit on the upper floor, and a usable rooftop terrace.
The east-facing orientation is not just a vastu preference. It translates into real structural, thermal, and resale advantages that compound across three floors.
This guide covers the full picture: room-by-room floor plans for all three floors, east-facing vastu placements, realistic construction costs by city tier, and the structural economics that make a three-floor east-facing build smarter than stopping at two.
The Structural Dividend: Why G+2 Is the Cost Optimum for a 30×40 East-Facing Plot
Most homeowners think about floors in terms of "how much can I build?" The better question is: at what floor count does cost-per-sqft reach its lowest point?
On a 30×40 plot, the answer is three floors.
30×40 east-facing G+2 — overview of the three-floor configuration delivering 2,100+ sq ft
When your structural engineer designs for G+2, the foundation is engineered for the full three-floor load from day one. The cost of soil testing, pile or strip foundation, plinth beam, and waterproofing is a fixed overhead — regardless of whether you build one floor or three. That overhead works out to roughly ₹180–220 per sq ft of total built-up area when spread across the full G+2.
If you build only the ground floor, that same cost lands on 750 sq ft instead of 2,250 sq ft.
The numbers:
| Scenario | Foundation + Plinth Cost | Spread Over | Per Sq Ft Overhead |
|---|---|---|---|
| Ground floor only (G) | ₹4–6 lakh | 750 sq ft | ₹533–800/sqft |
| Full G+2 | ₹4–6 lakh | 2,220 sq ft | ₹180–270/sqft |
That is the structural dividend. You are amortising the most expensive part of construction — the work below the ground floor slab — across three times the area. The second floor, which carries no foundation cost whatsoever, ends up costing 30–40% less per sq ft than the ground floor.
Combined with east-facing's thermal advantage (morning light, no harsh afternoon western exposure) and vastu compliance, the 30x40 house plan 3 floor east facing is arguably the most efficient three-floor configuration you can build on a standard BDA/BBMP-size plot.
East-Facing Advantages: Thermal, Vastu, and Market Value
Before the floor plans, it is worth understanding why east orientation matters — structurally, thermally, and financially.
Sun path analysis: east facade receives direct light from 6 AM to 10:30 AM only — afternoons stay shaded and cool
Thermal performance. The sun rises in the east and tracks south by noon. Your east-facing facade receives direct sunlight only in the morning — roughly 6 AM to 10:30 AM in Bangalore, Hyderabad, Chennai, and most of peninsular India. After that, the front of your house is in shade for the rest of the day. This means:
- Living rooms and bedrooms facing east stay cooler in the afternoon
- Reduced AC load during May to September
- Natural passive warmth in winter mornings (especially useful in Pune, Delhi NCR, Hyderabad)
Monsoon advantage. In coastal Indian cities like Chennai, Kochi, and Mangalore, the prevailing southwest monsoon means rain falls from the west and southwest. Your east facade is on the leeward side — reducing wall dampness and water penetration significantly.
Vastu premium. East is the direction of Surya (the sun) in Vastu Shastra. Buyers in the resale market specifically seek east-facing homes. Many will pay a 5–8% premium. On a ₹60–80 lakh construction, that is ₹3–6 lakh of inherent market value built into your orientation choice.
Ground Floor Plan: Function and Welcome
Your ground floor does two jobs. It welcomes guests, and it houses your most-used daily living spaces. On a 30×40 east-facing plot, the ground floor can also function as an independent 1BHK unit for elderly parents or tenants.
Ground floor layout — 30×40 east-facing: covered parking, living (NE), kitchen (SE), pooja (NE corner), bedroom (SW)
Typical ground floor layout (net built-up ≈ 720–750 sq ft):
| Space | Dimensions | Vastu Zone |
|---|---|---|
| Covered parking / entrance porch | 10×18 ft | Front east |
| Living room | 12×14 ft | NE quadrant |
| Pooja room | 6×6 ft | NE corner |
| Dining area | 10×10 ft | Centre-north |
| Kitchen | 10×12 ft | South-east |
| Bedroom 1 (guest or elderly) | 11×12 ft | South or SW |
| Attached bathroom | 5×8 ft | W adjacent to bedroom |
| Common toilet | 4×6 ft | NW |
| Staircase | 3.5×12 ft | SW zone |
The main door is placed on the east wall — ideally towards the NE quadrant of the east face. This is the optimal vastu position for east-facing homes. It catches morning light, creates a welcoming porch experience, and aligns with the Ishanya (NE) direction.
The kitchen in the SE corner follows vastu (agni corner — the direction of fire). It also makes practical sense. The cook gets warm morning light, and kitchen exhaust travels away from the living areas.
At 12×14 ft, the living room is large enough for an L-shaped sofa set, a dining extension, and a TV unit — without feeling cramped. The 11×12 ft ground floor bedroom works well for elderly parents who prefer ground-level access without stairs.
For planning your ground floor setbacks and room sizing standards across major Indian cities, the home building guide is a useful starting reference.
First Floor Plan: The Primary Family Core
The first floor is where the primary family lives day to day. It gets the best of east morning light through the balcony and is elevated enough to escape street-level noise and dust.
First floor layout — master bedroom (SW), two more bedrooms, east-facing balcony, family lounge (NE)
Typical first floor layout (net built-up ≈ 720–750 sq ft):
| Space | Dimensions | Vastu Zone |
|---|---|---|
| Master bedroom | 12×14 ft | SW corner |
| Master bathroom (attached) | 5×8 ft | W or NW |
| Bedroom 2 | 11×12 ft | NW |
| Bedroom 3 / Kids room | 10×11 ft | NE or E |
| Common bathroom | 5×7 ft | NW |
| East-facing balcony | 5×10 ft | East |
| Family lounge | 10×12 ft | N or NE |
| Passage + staircase | — | S or SW |
The master bedroom in the SW corner is the key vastu placement for east-facing G+2 homes. The head of the family rests in the SW zone, with the sleeping head pointing south — ensuring good rest and authority as per vastu texts. At 12×14 ft, this room accommodates a king-size bed, two side tables, a 4-door wardrobe, and a small study corner with room to spare.
The east-facing 5×10 ft balcony off the family lounge is one of the best features of this floor. Morning chai on an east balcony, watching the sunrise at 6:30 AM — it is a lifestyle element that buyers and tenants notice immediately.
Bedroom 3 at 10×11 ft in the NE or east zone gets the most morning light of any room on this floor. It works well as a kids' room or a home office where focus and clarity matter.
Second Floor Plan: Rental Income and Future Flexibility
The second floor is where your 30x40 house plan 3 floor east facing pays its biggest structural dividend. By the time two floors are complete, the frame is in place. The second floor adds approximately 700–720 sq ft at 30–40% lower marginal cost per sqft than the ground floor.
Second floor layout — two bedrooms, study/flex room, open terrace (10×18 ft) for solar panels or a kitchen garden
Typical second floor layout (net built-up ≈ 700–720 sq ft + open terrace):
| Space | Dimensions | Notes |
|---|---|---|
| Bedroom 4 | 12×13 ft | Can be rented independently |
| Bedroom 5 | 10×11 ft | Kids, home office, or visiting family |
| Common bathroom | 5×7 ft | — |
| Study / flex room | 9×10 ft | Meditation, library, or home office |
| Open terrace | 10×18 ft | Solar, garden, or laundry |
| Staircase landing | — | Terrace access |
Three ways to use your second floor:
-
Extended family living. Married children or in-laws get a semi-independent 2BHK with their own study and bathroom — private enough for autonomy, close enough for family proximity.
-
Rental income. A 2BHK on the second floor in Bangalore rents for ₹15,000–28,000/month depending on locality. In Hyderabad and Chennai, similar rents apply. Over 10 years with a conservative 5% annual increase, that unit generates ₹25–35 lakh in cumulative rent — substantially offsetting the ₹14–20 lakh it costs to build that floor.
-
Grow-into space. Build the shell at G+2 construction stage. Leave the second floor unfinished and complete it 3–5 years later when your budget or family size dictates. The structural cost is already absorbed at the G+2 stage.
The open terrace (approximately 10×18 ft after the staircase enclosure and parapet) accommodates 4–6 solar panels (a 4 kW system), reducing your electricity bill by ₹1,800–2,500/month. The east-facing orientation means the terrace receives 4–5 hours of direct morning sun — enough for tomatoes, curry leaf, and herbs in raised beds.
Vastu Compliance: The Full Three-Floor Grid
Vastu Shastra for a multi-floor east-facing home extends beyond the ground floor. Each floor has its own vastu logic, and the vertical placement of rooms across floors matters.
Vastu zone mapping across G, F1, F2 for a 30×40 east-facing plot — all critical rooms correctly positioned
Key vastu rules for east-facing G+2:
- Main entrance: East wall, towards NE. The Ishanya corner — most auspicious for east-facing homes.
- Kitchen: SE on every floor where a kitchen exists. The agni (fire) zone.
- Master bedroom: SW on first floor. Sleeping head pointing south or east.
- Pooja room: NE corner on ground floor. Never place it above or below a toilet.
- Bathrooms/toilets: NW or W zone. The NE toilet is the most common vastu violation in compact Indian plots — avoid it entirely.
- Staircase: S or SW zone. Clockwise direction as you ascend (rising from east to west).
- Overhead water tank: SW zone on terrace. Heavy weight in SW is considered grounding and stabilising.
- Children's study: NE or E zone for maximum focus and clarity.
- Home office (adults): NW or W zone.
A vastu-compliant east-facing layout does not require compromising on room sizes. The SE kitchen and SW master bedroom are structurally efficient choices too — they create a natural flow from public (entry, living, dining) to private (bedroom) zones without crossed circulation paths.

Elevation Design: Making Three Floors Look Proportionate
Three floors on a 30×40 plot can easily become a vertical box if not designed with care. The right elevation balances height with horizontal elements to create visual rhythm and kerb appeal.
East-facing elevation detail — stone cladding on ground, white render above, cantilevered balcony with glass railing
Key elevation elements for this configuration:
-
Entrance canopy / porch. A 5×6 ft covered entrance porch with a steel canopy or RCC slab adds depth to the ground floor. It creates a transition zone between street and home — and keeps your main door dry during monsoon.
-
East-facing first floor balcony. The 5×10 ft balcony breaks the vertical monotony of the elevation. Full-height frosted glass railings or an MS grille with horizontal fins give a modern look while maintaining privacy from the street.
-
Cladding contrast. A two-tone finish works well — lighter smooth render on the upper floors, textured stone or exposed aggregate cladding on the ground floor. This draws the eye upward without making the structure look top-heavy.
-
Consistent window proportions. Living room windows on the ground floor: 5×5 ft. Bedroom windows on upper floors: 4×4 ft. Consistent sizing creates visual order across the elevation.
-
Terrace parapet. A subtle jali screen or slatted concrete parapet on the terrace level is both functional (privacy for terrace activities) and visually interesting — it gives the building a clean top edge rather than a blunt wall.

Construction Cost: Floor-by-Floor Breakdown
Here is where the structural amortisation angle becomes tangible. The following cost distribution assumes a typical mid-spec Tier-1 city build (Bangalore, Hyderabad, or Chennai).
Construction cost by floor and city tier — foundation costs amortised across 2,220 sq ft of G+2
Cost per floor (Tier-1 city, mid-spec construction):
| Floor | Built-up Area | Cost/sqft | Estimated Total |
|---|---|---|---|
| Ground floor (G) | 750 sq ft | ₹3,000–3,500 | ₹22.5L–26.25L |
| First floor (F1) | 750 sq ft | ₹2,200–2,800 | ₹16.5L–21L |
| Second floor (F2) | 720 sq ft | ₹2,000–2,600 | ₹14.4L–18.7L |
| Total G+2 | 2,220 sq ft | ₹2,400–3,000 avg | ₹53L–66L |
The ground floor is the costliest because it includes soil testing, foundation work, plinth beam, anti-termite treatment, and a thicker ground slab with waterproofing. By the second floor, you are paying only for columns, beams, slab, walls, plaster, and finish. No foundation cost at all.
Cost by city tier:
| Tier | Cities | Range/sqft | Total G+2 (2,220 sqft) |
|---|---|---|---|
| Tier-1 | Bangalore, Mumbai, Hyderabad, Chennai | ₹2,000–3,500 | ₹44L–78L |
| Tier-2 | Pune, Kochi, Coimbatore, Mangalore | ₹1,500–2,500 | ₹33L–55L |
| Tier-3 | Smaller towns | ₹1,200–2,000 | ₹27L–44L |
These are civil and finishing costs. Add 10–15% for architect fees, plan sanction approvals, electrical, plumbing, and landscaping.

Living in an East-Facing G+2: What It Actually Feels Like
The numbers make the case. But let us also talk about what it feels like to live in this home day to day.
Morning on the east-facing first floor balcony — warm light, cross-ventilation, and the quiet of elevation
By 7 AM, the living room on the ground floor and the family lounge on the first floor are filled with warm, natural east light. The master bedroom on the SW corner is still cool and dim at that hour — ideal for sleeping in on weekends. The SE kitchen catches the first light of the day, making early-morning cooking feel less like a chore.
In monsoon, your east-facing walls stay drier than any other orientation in coastal Indian cities. The rain falls from the south and southwest — your most important facade is on the sheltered side.
In winter, that same east glass becomes a passive solar collector. A well-glazed east living room warms naturally by 8 AM without any heating system — particularly noticeable in Pune, Delhi NCR, and Hyderabad from November to February.
The second-floor open terrace becomes a seasonal outdoor room. Evening gatherings in the east terrace (in comfortable shade by noon) with a small kitchen garden create the kind of experience that makes a 1,200 sq ft plot feel far more generous than its footprint.

Frequently Asked Questions
How many bedrooms can you fit in a 30x40 3 floor east facing house plan?
A 30×40 G+2 east-facing home can comfortably fit 4–5 bedrooms across three floors. The typical split: one bedroom on the ground floor (for elderly parents or guests), three on the first floor including the master, and one or two on the second floor for extended family or rental use. With a built-up area of approximately 2,200 sq ft, each bedroom has room for standard Indian furniture without compromise. The east-facing orientation ensures at least two bedrooms receive direct morning light daily.
How much does it cost to build a G+2 house on a 30x40 plot in Bangalore?
In Bangalore (Tier-1 city), construction cost for a 30×40 G+2 — approximately 2,200–2,250 sq ft built-up — ranges from ₹44 lakh to ₹78 lakh for mid-spec to premium finishes. Budget construction (basic tiles, standard fittings) comes in at ₹44–55 lakh. Mid-spec construction with decent finishes runs ₹55–65 lakh. Premium finishes push costs to ₹70–78 lakh. Add 10–15% for architect fees, BBMP plan sanction, electrical, plumbing, and external work. Use the Ongrid cost calculator for a more precise city-specific figure.
Is east facing good for a 3 floor house as per Vastu Shastra?
Yes, east-facing is considered highly auspicious in Vastu Shastra for multi-floor homes. The key requirements for a G+2 east-facing plan: main door on the east wall towards the NE quadrant, kitchen in the SE (agni) zone, master bedroom in the SW corner of the first floor, and pooja room in the NE corner of the ground floor. The staircase belongs in the S or SW zone. When these placements are observed, an east-facing G+2 is one of the most vastu-compliant configurations possible on a standard Indian plot.
What are the BBMP setback rules for a 30x40 plot in Bangalore?
Under current BBMP residential regulations, a 30×40 (1,200 sq ft) plot typically observes: front setback — 3 ft minimum; rear setback — 3 ft; side setbacks — 3 ft each. The permissible FAR (Floor Area Ratio) is 1.75–2.25 depending on the road width fronting your plot, allowing 2,100–2,700 sq ft of total built-up area. This is comfortably enough for G+2 with good room sizes. Always verify current norms with your local ward office or a licensed architect, as exact rules vary by zone, road category, and plot dimensions.
Can I earn rental income from a 30x40 G+2 east facing house?
Yes, and the second floor on a 30×40 G+2 is specifically well-suited for independent rental. Configured as a 2BHK with a separate staircase entrance, a second-floor unit in Bangalore rents for ₹15,000–28,000/month depending on locality and finish level. In Hyderabad and Chennai, similar rental ranges apply. Over a 10-year horizon with a conservative 5% annual increase, that unit generates ₹25–35 lakh in cumulative rent — significantly offsetting the ₹14–20 lakh cost to build it. East-facing units command better rents due to vastu compliance and morning light.
How long does it take to build a 30x40 G+2 house?
A 30×40 G+2 typically takes 18–24 months from foundation to possession with uninterrupted construction. Approximate breakdown: foundation and ground floor slab — 3–4 months; first floor structure and slab — 3–4 months; second floor structure — 3–4 months; finishing (tiling, electrical, plumbing, painting) — 5–6 months. Common delays occur during monsoon (June–September), during BBMP/GHMC plan sanction (which can take 2–4 months), and during material or labour shortages. Build a 20% buffer into your project timeline to account for these variables.
What is the difference between built-up area and carpet area in a 30x40 G+2?
Built-up area (BUA) for a 30×40 G+2 includes all walls, columns, balconies, and enclosed spaces — typically 2,100–2,250 sq ft. This is what you pay construction cost on. Carpet area is the usable floor space inside rooms — typically 70–75% of BUA, or about 1,470–1,690 sq ft for this configuration. When comparing design options or negotiating with contractors, always check carpet area, not BUA. A well-designed 30×40 G+2 plan from Ongrid maximises carpet area by keeping corridor widths lean and wall thicknesses structurally optimised.
