G+2 House Design: 3 Floor Plans, Elevation & Cost

A 3 floor house plan, usually called G+2 (ground plus two upper floors), is the most efficient way to get a large home or several independent units out of a mid-sized urban plot in Delhi NCR. On a 1,000 sq ft floor plate, G+2 gives you about 3,000 sq ft of built-up area, which costs roughly ₹61.5–85.5 lakh at standard specification in 2026 at NCR base rates. This guide covers three practical G+2 house design layouts with room sizes, the structural points that matter at three storeys, G+2 elevation ideas and floor-by-floor costs.

When a G+2 House Makes Sense

A three storey house plan in India is usually chosen for one of three reasons: a joint family that wants a floor per generation, an owner who wants rental income from one or two floors, or a small plot where two floors simply do not give enough rooms. It works best on plots from about 100 to 250 gaj (900–2,250 sq ft).

• Permissions first: the number of floors, total height, FAR, stilt rules and parking requirements vary between Delhi, Gurugram, Noida, Faridabad and Ghaziabad, and with plot size and road width. Confirm what your plot allows before paying for a design.
• Future-proofing: even if you build only G+1 today, design the foundation, columns and stair for G+2.
• Accessibility: three floors are a real climb. Plan a lift shaft from day one, even if the lift is installed later.

Disclaimer: bye-laws and approval requirements change and differ by authority; always check the current rules on your authority's official portal or with a registered architect.

Layout 1: Joint Family Home, One Floor Per Generation

Shown on a 30'×50' plot with about 1,050 sq ft covered per floor.

Ground floor: parents and shared living

• Car porch: 10'×17' in front
• Drawing room: 12'×15'; dining 10'×12'
• Main kitchen: 9'×11', with utility 4'×7'
• Parents' bedroom: 12'×13', with attached bathroom 5'×8' and grab bars
• Pooja: 5'×5'; stair 7'×12' with a 5'×5' lift shaft beside it

First floor: main family

• Family lounge: 12'×16'; kitchenette 6'×8' so the floor can run independently
• Master bedroom: 12'×14', with bathroom 5'×9'
• Second bedroom: 11'×12', with attached bathroom 4'6"×7'
• Front balcony: 4'×14'

Second floor: children or guests, plus terrace

• Two bedrooms: 11'×12' each, with attached bathrooms
• Study or home office: 10'×11'
• Covered terrace sit-out: 12'×14', with the rest of the roof open

Layout 2: Owner's Floor Plus Two Rental Units

Shown on a 25'×50' plot with about 950 sq ft covered per floor. Each floor is an identical self-contained 2BHK.

• Living-dining: 12'×18'
• Kitchen: 8'×10', with a 3'×5' utility balcony
• Master bedroom: 12'×13', with attached bathroom 5'×8'
• Second bedroom: 11'×11'; common bathroom 4'6"×7'
• Front balcony: 4'×12'
• Common stair and lift at one side, entered from the front without passing through any flat

Separate electricity meters, separate water connections or sub-meters, and stacked kitchens and bathrooms keep tenants independent and maintenance simple. Our house plan for rental income guide covers unit mix and returns, and our 25x50 house plan article shows this plot's single-family options.

Layout 3: Owner's Duplex Plus One Rental Floor

A popular middle path: the owner occupies ground and first as a duplex with an internal stair, and the second floor is a separate 2BHK reached by an external or common stair. On a 30'×40' or 30'×50' plot, the duplex typically holds:

• Ground: living 12'×15', dining 10'×11', kitchen 8'×10', parents' bedroom 11'×12' with attached bathroom, powder room
• First: master bedroom 12'×13' with bathroom 5'×8', second bedroom 11'×12', family lounge 10'×12', front balcony
• Second: a self-contained 2BHK, as in Layout 2

The key is two stairs: a compact internal stair of about 3' flights for the duplex, and a separate common stair to the rented floor, planned so neither compromises the other's privacy. On a 30 ft frontage, the common stair can sit at the front corner beside the car porch, where it also shields the house from street noise and sun.

Structural and Services Points at Three Storeys

A G+2 house carries noticeably more load than a G+1, and mistakes here are expensive to fix.

• Soil and foundation: get a soil assessment where conditions are uncertain, and have a qualified structural engineer design the foundation for the full G+2 load.
• Column grid: align columns vertically through all floors; shifting a column on an upper floor to suit a room is a common and costly error.
• Earthquake detailing: Delhi NCR falls in a relatively high seismic zone, so reinforcement detailing must follow the applicable codes; this is the engineer's job, not the contractor's.
• Lift shaft: reserve the shaft and pit at the start. Our home lift cost guide covers options and budgets.
• Water pressure: the top floor needs an overhead tank height or a pressure pump that gives usable shower pressure.

Our structural and MEP team designs foundations, frames and services together, so the drawings match on site.

G+2 Elevation Ideas

Three floors give height to work with, but also a risk of a flat, stacked-box front. Approaches that work:

• Vary the floors: set the top floor back slightly or give it a different material so the building does not read as three identical layers.
• Vertical feature strip: run stone cladding or aluminium louvres up the stair and lift core to tie the floors together.
• Balcony frames: projecting concrete or ACP frames around the first- and second-floor balconies add depth and shade.
• Durable materials: at three storeys, facade maintenance needs scaffolding, so choose stone, tile or quality exterior paint over finishes that need frequent attention.

G+2 House Construction Cost (2026)

Indicative 2026 costs at the NCR base rate of ₹1,650–2,050 per sq ft (basic), ₹2,050–2,850 (standard) and ₹2,850–4,200 (premium). Excludes land, design fees, approvals, lift, boundary wall and interiors.

Many owners build in phases. Cumulative cost on a 1,000 sq ft floor plate, floor by floor:

City factors shift these figures: the 3,000 sq ft standard home comes to roughly ₹66.4–92.3 lakh in Gurugram (1.08), ₹64.6–89.8 lakh in Delhi (1.05) and ₹59.7–82.9 lakh in Faridabad, Ghaziabad or Greater Noida (0.97). Building in phases usually costs more overall than building in one go, because of remobilisation and roof waterproofing done twice. Check your own plan in the construction cost calculator.

Before tendering, make sure the drawings fix the items that move a G+2 budget most: the number of bathrooms and kitchens (each self-contained floor adds a full set), the elevation cladding, the flooring specification and the lift. Contractor quotes built on the same detailed drawings can then be compared line by line instead of on a headline per sq ft rate.
