40x60 House Plan | 4 Floor South Facing Design
A 40×60 south facing 4-floor home — vertical urban living from a 2,400 sq ft city plot
Your 40x60 4 floor south facing house plan is a direct answer to one of urban India's most common challenges: fitting a complete family life — covered parking, a parents' suite, a primary residence, and a future rental unit — into a single city plot. With south orientation locking in consistent natural light on every floor all year, this G+3 design delivers approximately 6,800 sq ft of usable space from a 2,400 sq ft footprint.
This guide covers everything you need. Room-by-room floor plans for all four floors. Direction-specific vastu guidance for south-facing homes. A 3D elevation breakdown. And construction cost estimates across all three quality tiers. Whether you are building for a joint family or planning a home with rental income built in, this south facing 40x60 layout gives you a practical blueprint to start from.
Why South Facing Works Best for a G+3 Design
South-facing plots carry an undeserved reputation in vastu circles. For a four-floor home, south facing is arguably the strongest orientation you can have.
South orientation delivers balanced daylight to all four floors across every season
The sun in India travels from east to west along a path that stays largely south of the zenith throughout the year. A south-facing facade catches morning light on its southeast corner and afternoon warmth on the southwest. Critically, upper floors on a south-facing building are never shadowed by buildings across the street — sunlight clears neighboring rooflines easily. This means your third-floor bedrooms feel just as bright and airy as your ground-floor living room.
In cities like Bengaluru, Hyderabad, and Pune, south-facing plots in dense residential layouts often command an 8–12% market premium over east-facing plots of equal size. Buyers and tenants actively seek south-facing flats for their light quality and winter warmth. For a G+3 home where you plan to rent out one or two upper floors, this is a measurable financial advantage.
A well-designed south facing home cross-ventilates efficiently too. Openings on the south and north walls pull summer breezes through every room. This reduces dependence on air conditioning — a significant saving over the lifetime of the building.
40x60 4 Floor South Facing House Plan: Floor-by-Floor Layout
The following plans assume standard setbacks: 5 ft front, 3 ft on each side, and 3 ft rear. Each floor plate is approximately 34×52 ft, yielding about 1,700–1,750 sq ft of built-up area per level. Total built-up area across all four floors: approximately 6,800 sq ft.
Ground Floor — Parking, Parents' Suite and Family Living
Ground floor: dual covered parking, parents' bedroom suite in the southwest, and connected living spaces
The ground floor carries the most public functions of the home.
A 20×18 ft covered parking bay on the south-facing front fits two cars side by side. A 6×4 ft entry porch with a landing steps leads into a 6×8 ft foyer. The foyer opens right into the main living room (14×16 ft) and ahead into the dining area (10×12 ft).
The modular kitchen occupies the southeast corner at 9×12 ft. This aligns with the vastu Agni zone and keeps cooking activity away from the living area sightline. A 6×8 ft utility and wash zone connects behind the kitchen toward the rear.
The parents' bedroom suite sits in the southwest corner: a 12×13 ft room with an attached 5×8 ft bathroom. Placing elderly family members in the southwest satisfies vastu. Ground-floor location means no stairs for parents or in-laws. A 4×5 ft guest toilet near the entry serves visitors. The staircase — 10×12 ft landing area — rises from the rear-centre of the plan, keeping the living zone uninterrupted.
First Floor — Primary Family Residence
First floor: self-contained 3BHK primary residence with south balcony and full kitchen
The first floor is the primary family's home — a complete, self-contained 3BHK.
The south-facing balcony (5×14 ft) runs across the full front facade. Morning light fills this space from 7 AM onward, making it ideal for breakfast, a plant wall, or a reading corner. It is the defining feature of this floor.
The master bedroom (13×15 ft) anchors the southwest corner with a walk-in wardrobe nook and an attached bathroom (6×8 ft, double vanity). Bedroom 2 (11×13 ft) has its own attached bath (5×7 ft) and an east-facing window. Bedroom 3 (10×12 ft) works well as a children's room or home office.
The family living room (14×16 ft) is centrally placed, connecting to dining (10×12 ft) and a modular kitchen (9×12 ft) in the southeast. A 5×7 ft common bathroom serves the third bedroom.
Second Floor — Independent Rental Unit or Second Family
Second floor: a fully independent 3BHK, ideal for rental income or a second family unit
The second floor mirrors the first floor in layout but is designed for independent living. A separate entrance from the staircase landing means this floor can operate as a self-contained rental unit without sharing any space with the floors below.
Master bedroom: 12×14 ft with attached bath (5×7 ft). Bedroom 2: 10×12 ft. Bedroom 3: 10×11 ft. Living room: 12×14 ft. Kitchen: 8×10 ft. South balcony: 5×12 ft.
In Bengaluru or Hyderabad, a 3BHK floor unit like this rents for ₹18,000–₹28,000/month depending on locality and finish quality. At that yield, this floor pays back its own construction cost in approximately 10–13 years — while the rest of the home remains your own.
Third Floor — Penthouse Suite with Terrace Garden
Third floor: private 2BHK penthouse with south-facing deck and 400 sq ft open terrace garden
The third floor is the premium level of the home. Designed as a 2BHK penthouse with an open terrace garden, it offers a private, elevated retreat with unobstructed south views.
Master bedroom: 12×14 ft with attached bath (6×8 ft) and a private 6×14 ft south-facing deck. Second bedroom: 10×12 ft, doubles as a home office. Living room: 12×14 ft opening onto the deck. Kitchen: 8×10 ft. Study/flex room: 9×10 ft.
The open terrace garden (approximately 400 sq ft) occupies the rear portion. Solar panels, a rooftop kitchen garden, or simply an outdoor seating area — this space is entirely yours to shape.
Vastu Guidelines for a South Facing 40x60 G+3
South-facing homes are fully vastu-compliant when planned correctly. The single most important rule is entrance placement.
Vastu grid for a 40×60 south facing plot — 4th pada entrance, zone placement per direction
Entrance: On a south-facing plot, divide the 40 ft south wall into 9 equal padas of approximately 4.4 ft each, counting from the east corner. The 4th pada — falling roughly 13–18 ft from the east corner — is the Gruhya pada: the one auspicious entrance position on the south wall. Avoid the 1st, 2nd, and 3rd padas, which fall in the Yama zone and are considered inauspicious. Avoid the extreme west end of the south wall as well.
Kitchen: Place the kitchen in the southeast corner (Agni zone) on every floor. This is consistent for any facing direction and keeps the fire element correctly oriented.
Master Bedroom: The southwest corner on each floor is the ideal placement. Southwest is governed by the earth element and promotes stability, grounded rest, and authority. This is why the parents' suite occupies the ground-floor southwest, and the primary master bedroom anchors the first-floor southwest.
Pooja Room: The northeast corner of the ground or first floor is the Ishanya zone — spiritually charged, receiving the first morning light of the day. A 5×6 ft pooja room here is ideal.
Staircase: Position the staircase in the south, southwest, or west portion of the building. Never place it in the northeast corner. The central-rear staircase in this layout satisfies this requirement.
Water Storage: Underground sump in the northeast. Overhead tank on the southwest or west side of the terrace roof — never over the northeast corner.
For a detailed vastu analysis of your specific plot, book a consultation with an Ongrid architect before finalising your layout.
3D Elevation and Design Highlights
Four floors of south-facing facade give you the canvas for a truly striking street presence. The design choices below make this 40×60 G+3 stand out without being decorative for the sake of it.
Contemporary 40×60 south facing G+3 elevation — tiered balconies, textured cladding, and clean rooftop parapet
Tiered balconies are the signature feature. Each floor's south-facing balcony is offset slightly from the one below, creating a stepped, cascading profile. This visual rhythm defines the facade and also prevents rainwater from dripping directly onto the floor below.
The ground-floor parking portico uses double-height columns in a tapered, contemporary profile — modern rather than ornate. A textured stone cladding panel on the east end of the facade breaks the flat surface and adds material depth.
Upper floors alternate between smooth painted plaster in warm white and exposed brick insets at the bedroom level. The third-floor parapet features a clean horizontal aluminium rail in powder-coated dark bronze, giving the roofline a precise, finished look.
Window sizing increases with height. Ground-floor windows are 3×4 ft — practical and secure. First-floor windows are 4×5 ft. Second and third floors feature full-height 2×6 ft vertical windows in dark bronze aluminium profiles that flood rooms with south light.

Construction Cost Estimate for a 40x60 G+3
The total built-up area for this design is approximately 6,800 sq ft across four floors. Your construction cost depends significantly on finish quality and city.
Construction cost breakdown for a 40×60 G+3 home — three quality tiers
| Construction Tier | Rate (₹/sq ft) | Total Estimate |
|---|---|---|
| Tier 3 — Standard | ₹1,200 – ₹2,000 | ₹82 lakh – ₹1.36 crore |
| Tier 2 — Premium | ₹1,500 – ₹2,500 | ₹1.02 crore – ₹1.70 crore |
| Tier 1 — Luxury | ₹2,000 – ₹3,500 | ₹1.36 crore – ₹2.38 crore |
These rates cover civil structure, flooring, plumbing, electrical, doors, windows, internal plaster, and basic kitchen and bathroom fittings. Modular kitchens, premium sanitary ware, and interior design are additional.
Key cost drivers specific to a G+3 build:
- RCC frame structure: A four-floor building requires a column-beam RCC frame with isolated or pile foundations. This adds ₹80–₹120/sq ft over a load-bearing design.
- Staircase: A well-finished staircase with handrails and landings adds ₹3–₹5 lakh per floor change.
- Waterproofing: Roof and bathroom waterproofing for a 4-floor building is non-negotiable. Budget ₹40–₹60/sq ft for quality waterproofing.
- Facade cladding: Stone or composite cladding on 15–20% of the south facade adds ₹12–₹18 lakh for a full-height finish.

Frequently Asked Questions
Is a south facing 40x60 plot good for a G+3 house?
Yes — south facing is one of the best orientations for a G+3 design. Upper floors receive consistent natural light year-round because the sun's arc keeps the south side unobstructed throughout the day. Dense urban neighbours to the north cast no shadow on your south facade. As long as you place the main entrance in the 4th pada from the east on the south wall (the Gruhya pada), the home is fully vastu-compliant.
What is the total built-up area of a 40x60 4 floor house?
With standard setbacks — 5 ft front, 3 ft on each side, and 3 ft rear — the net floor plate per level is approximately 34×52 ft, or around 1,700–1,750 sq ft. Across four floors (ground plus three upper floors), the total built-up area comes to approximately 6,800–7,000 sq ft. Your local municipal authority's FAR and coverage rules determine the exact permissible area — always verify before finalising your design drawings.
How much does it cost to build a 40x60 G+3 house in India?
For approximately 6,800 sq ft of built-up area, construction costs range from ₹82 lakh at Tier 3 standard finish to ₹2.38 crore at Tier 1 luxury finish. Most urban homeowners building a quality G+3 home budget ₹1.2–₹1.7 crore for Tier 2 finishes. These figures cover civil work, flooring, plumbing, and electrical. Modular kitchens, premium sanitary ware, and landscaping are separate. Use Ongrid's construction cost calculator for a city-specific estimate.
Can the second floor function as an independent rental apartment?
Yes. The second floor in this design is laid out as a self-contained 3BHK unit with its own kitchen, bathrooms, and a separate entrance from the main staircase landing. No shared access with the primary family's floors is required. In Bengaluru or Hyderabad, a well-finished floor unit like this rents for ₹18,000–₹28,000 per month. The rental income from one floor can substantially offset your home loan EMI over the long term.
What structural system is required for a 40x60 4-floor home?
A G+3 residential building on a 40×60 plot must use an RCC (Reinforced Cement Concrete) column-beam frame structure with isolated footings — or pile foundations where soil conditions require it. Load-bearing brick construction is not structurally safe for four floors. You will need a structural engineer's stamped drawings submitted to and approved by your local municipal authority before construction begins. Ongrid's design packages include structural engineering coordination for all multi-floor projects.
How does vastu apply to a south facing G+3 — floor by floor?
Apply the same rules consistently on every floor. Entrance pada: 4th from east on the south wall for the main door. Kitchen: southeast corner (Agni zone) on all floors. Master bedroom: southwest corner for stability and rest. Pooja room: northeast corner of the ground or first floor (Ishanya zone). Staircase: south or southwest quadrant throughout. Overhead water tank: southwest or west of the terrace roof. A dedicated vastu consultation with an Ongrid architect will map these rules to your exact plot dimensions.
How long does it take to get a complete 40x60 G+3 design from Ongrid?
