Why staircase planning matters
In a G+1, G+2 or G+3 home, everyone uses the staircase many times a day: children, elderly parents, guests and tenants. A cramped or steep staircase is tiring and unsafe, while an oversized one eats into valuable floor area on a small Bangalore plot.
The staircase also decides how the floors connect. If you plan to rent out a floor, its position determines whether tenants can come and go without passing through your home. That is why we fix the staircase early in the design, alongside the room layout. Our guide to duplex house planning shows how stairs shape the plan of a two-level home.
Comfortable dimensions
The National Building Code of India sets a minimum clear width of 0.9 metres for stairs in individual residential houses. For comfort and for moving furniture, most families are happier with a width of about 1.0 to 1.1 metres.
For the steps themselves, these ranges work well in homes:
- Riser (height of each step): about 150 to 175 mm. Lower risers are easier for elderly family members.
- Tread (depth of each step): about 250 to 300 mm, so the whole foot rests comfortably.
- Headroom: keep a clear height of at least 2.1 metres above every step, measured to the beam or slab above.
- Handrail: a firm rail at around 0.85 to 0.9 metres above the step, continuous along the flight.
- Landing: long flights should be broken with a landing, which is also a safe resting point.
Keep every riser in a flight the same height. Uneven steps are one of the most common causes of trips. Your architect will work out the exact numbers from your floor-to-floor height.
Common staircase types
- Dog-legged: two flights running in opposite directions with a landing between them. It is compact and the most common type in Bangalore homes.
- L-shaped (quarter turn): two flights at right angles. It fits well in a corner and feels open.
- U-shaped (open well): like a dog-legged stair but with a gap between flights. It needs more space but feels grand and lets light through.
- Straight: simple to build, but needs a long, narrow space and offers no resting point unless a landing is added.
- Spiral: saves space, but is harder to use and to move furniture on. Best for terrace access, not as the main stair.
Where to place the staircase
Placement depends on how the house will be used:
- Internal staircase: best for a single family using all floors. It keeps the home connected and secure.
- External or separate staircase: essential if an upper floor will be rented out, so tenants have their own entry. Many G+2 homes use one internal stair for the owner and a separate stair for rental floors.
- Near the entrance: makes it easy to reach upper floors without passing through the living room.
- Away from bedrooms: stairs can carry sound, so avoid placing them right against a bedroom wall where possible.

Light, ventilation and safety
A staircase with a window or skylight feels brighter and safer, and it can pull hot air up and out of the house. Our article on natural light and ventilation covers how to use the stair core for this.
Other safety points worth planning:
- Non-slip finishes on treads, especially near wet areas and outdoor stairs
- Light switches at both the top and bottom of each flight
- Balustrade gaps small enough that young children cannot slip through
- No doors that open directly onto a step
Finishes and materials
Granite is the most popular tread finish in Bangalore homes because it is durable and easy to clean. Wood or wood-look tiles add warmth for internal stairs. For railings, stainless steel, mild steel with powder coating and toughened glass are common options. See our flooring options guide to compare materials.
How much space and cost to allow
On a 30x40 plot, a comfortable dog-legged staircase with a landing typically needs a well of around 8 to 10 feet by 10 to 12 feet on each floor, depending on width and floor height. That area is repeated on every floor, so the staircase is a real part of your built-up area and your construction cost.
A few ways to use the space well:
- Use the space under the first flight for a store, a powder room or a small utility area
- Combine the staircase landing with a window for light and ventilation
- Plan the headroom carefully so the space under the stairs is usable
- In homes with a separate rental staircase, keep the owner's stair compact and the rental stair simple and durable
Decide early whether you may need a home lift in future. Leaving space beside the staircase for a lift shaft is far easier than finding it later. Our architects plan the staircase together with your package and floor plans, so the cost is clear in your quotation from the start.
Vastu considerations
Many families like to follow Vastu when placing the staircase. Commonly preferred positions are the south, west or south-west of the house, with the staircase climbing in a clockwise direction. Placing stairs at the centre of the home is usually avoided. Practical needs such as plot shape, road side and rental access also matter, so your architect will balance both.

Frequently asked questions
What is the minimum staircase width for a house in India?
The National Building Code sets a minimum clear width of 0.9 metres for stairs in individual houses. Most families prefer 1.0 to 1.1 metres for comfort.
What is a comfortable riser and tread size?
A riser of about 150 to 175 mm and a tread of about 250 to 300 mm is comfortable for most homes. Keep all risers in a flight equal.
Should the staircase be inside or outside the house?
Use an internal staircase if one family uses all floors. If you plan to rent out a floor, add a separate staircase so tenants have their own access.
