Executive Summary
A 30x50 plot measures 1,500 square feet — exactly 25% larger than the widely common 30x40 site. This extra 10 feet of depth unlocks significantly more design flexibility. A ground-floor-only 30x50 plan can fit a full 3BHK with dedicated parking for two cars and still leave room for a service area or garden.
A G+1 design on this plot yields 2,800–3,000 sq ft of built-up area — comfortably enough for a spacious 4–5 bedroom family home. It is also an outstanding plot size for duplex income properties, where the additional depth creates clean front-and-rear unit separation that a 30x40 cannot achieve.
At PlanMyPlot, our registered CoA architects have delivered 30x50 house plans for clients across Bangalore's outer ring road, Shivamogga, and tier-2 cities. Every design is Vastu-reviewed, BBMP/BDA-ready, and delivered in 7 days starting at ₹4,999.

30x50 House Plan Layouts
30x50 3BHK Ground Floor Plan
The 30x50 ground-floor plan is a significant step up from its 30x40 counterpart. The 10 additional feet of depth allows for a much larger living-dining combination (up to 16×18 ft as a single great room), a dedicated utility room behind the kitchen, and a rear garden or service yard — all on a single floor.
Typical Room Sizes
- • Master bedroom: 12×14 ft with attached bathroom
- • Bedroom 2 & 3: 10×12 ft each
- • Living + Dining (combined): 16×18 ft
- • Kitchen (L-shape): 8×12 ft
- • Utility room: 4×8 ft
- • Double car parking: 20×18 ft (2 cars side-by-side)
What the Extra 10 Feet Unlocks
- • Rear garden or sit-out (not possible on 30x40)
- • Dedicated utility/laundry room
- • Larger living area for extended family
- • Comfortable double car parking
- • Vastu-correct open space toward north or east
This layout suits families with elderly members who prefer no stairs, or homeowners planning to add an upper floor later. Structural columns can be designed to accommodate a first floor from day one.
30x50 G+1 — 4 or 5 BHK Plan
The G+1 configuration is where the 30x50 plot truly distinguishes itself. With approximately 2,700–3,000 sq ft of built-up area, this home comfortably houses 4–5 bedrooms with generous room sizes across two floors.
Ground Floor
- • Double car garage (20×18 ft)
- • Entrance foyer
- • Large living room (14×16 ft)
- • Dining area
- • Modular kitchen with utility (8×12 ft)
- • Parents' bedroom with attached bathroom (12×14 ft)
- • Staircase
First Floor
- • Master bedroom suite (14×14 ft) with bathroom, wardrobe & private sit-out
- • 2 additional bedrooms (10×12 ft each)
- • Common bathroom
- • Large roof terrace
- • Family lounge or study nook
The most popular configuration on 30x50 sites at PlanMyPlot: "Parents' suite on ground + master suite on first floor" — giving each generation privacy while sharing common spaces. This is the single most-loved layout we've delivered for Bangalore families.
30x50 Duplex House Plan
The 50-foot depth of a 30x50 site creates unique duplex possibilities that a 30x40 cannot achieve. Specifically, the front-and-rear unit configuration — where one unit faces the street and the other has a rear entrance — becomes practical. Both units can have a direct outdoor connection.
Front Unit (Street-Facing)
- • Independent street-facing entrance
- • 3BHK: living, dining, kitchen
- • 2 attached bathrooms
- • Front car parking
- • Private front yard
Rear Unit (Garden-Facing)
- • Independent rear entrance
- • 2–3BHK with private garden access
- • Own kitchen and bathrooms
- • Private rear sit-out/garden
- • Natural privacy from front unit
This configuration is increasingly popular in Bangalore's Sarjapur Road, Varthur, and HSR Layout areas. See our duplex house plan gallery →
Section 03
Vastu for 30x50 House Plans
A 30x50 site has a 3:5 proportion, making it slightly more rectangular than the ideal Vastu square. Vastu Shastra recommends compensating for this by keeping the building footprint as close to square as possible — for example, building a 30x40 structure within the 30x50 plot and using the remaining 10 feet as a north or east-facing garden or open terrace. This approach simultaneously improves Vastu compliance and enhances natural ventilation.
| Room | Vastu Direction | 30x50 Note |
|---|---|---|
| Main entrance | North, East, or Northeast | Easiest to achieve on a 30x50 — ample north or east frontage |
| Master bedroom | Southwest | Extra depth makes SW placement straightforward |
| Kitchen | Southeast | Same as any plot — clear southeast corner available |
| Pooja room | Northeast | Use the extra 10 ft depth to create a dedicated room |
| Garden / Open area | North or East | The remaining 10 ft of depth is ideal here |
| Underground sump | Northeast | Never in south or southwest |
| Staircase | South, West, or SW | Keep staircase away from Brahmasthan (centre) |
For south-facing 30x50 sites, the elongated depth is actually an advantage — it creates greater separation between the south entrance and the north rooms, exactly what Vastu recommends. Read the complete Vastu house plan guide →

30x50 vs 30x40 — How They Compare
The 30x50 offers considerably more design freedom than a 30x40 at a marginal additional cost. Here is an objective comparison:
| Feature | 30x40 (1,200 sq ft) | 30x50 (1,500 sq ft) |
|---|---|---|
| Plot area | 1,200 sq ft | 1,500 sq ft (+25%) |
| Ground floor built-up | ~900–1,050 sq ft | ~1,150–1,350 sq ft |
| G+1 built-up | ~2,100–2,200 sq ft | ~2,700–3,000 sq ft |
| Car parking | 1 car (standard) | 2 cars (comfortable) |
| Duplex configuration | Side-by-side units | Front-and-rear unit option |
| Garden/open area on ground | Very limited | Comfortable 150–200 sq ft |
| Construction cost (G+1) | ₹38L–₹46L | ₹48L–₹62L |
| Resale premium vs 30x40 | Baseline | 15–25% higher |
The construction cost difference between a 30x40 and 30x50 G+1 is approximately ₹10L–₹15L. However, the resale price difference is typically 15–25% higher, making the 30x50 a better long-term investment per rupee spent. Compare 30x40 house plans →

Design Tips from
Professional Architects
Use the 10 extra feet of depth for a rear garden, not more rooms — open space on a 30x50 dramatically increases ventilation and resale value.
Design the staircase in the south or southwest zone of the plot to keep the Brahmasthan (centre) open for a double-height void or skylight.
For the duplex configuration, invest in a well-designed external staircase — it should look like an architectural feature, not a fire escape.
In the G+1 layout, place the parents' bedroom on the ground floor (southwest) for Vastu compliance and to avoid stairs for elderly residents.
The 30-foot frontage allows for two cars parked side-by-side if the front setback is used correctly — discuss this with your architect from day one.
Use floor-to-ceiling windows on the north facade of the first floor to flood the upper bedrooms with soft, consistent natural light.
