3 BHK
Staircase Design for a 3 BHK
In a 3 bhk of 1,100-1,500 sq ft, the staircase typically works to Villa, two flights. A staircase is structure, circulation and sculpture at once. We resolve the going and the rise first — comfort is not negotiable for a design idea.

Planning note
Staircase at 3 bhk scale
At 1,100-1,500 sq ft, the constraint on a staircase is usually circulation rather than storage — there is enough wall to plan the volume in, but not enough floor to plan around a mistake. Villa, two flights is the dimension we hold to because it is the largest the room comfortably allows, not the largest that would fit on paper.
Households at this configuration consistently under-plan storage volume for a staircase, then add freestanding furniture later that the original layout never accounted for.
A 5mm shadow gap between tread and riser makes a heavy stone stair look lighter, and hides the tolerance between two site-cut pieces.
Continue the handrail past the top and bottom riser by 300mm. It is a code habit and it also reads as considered.
Where treads are book-matched or vein-continuous, the slabs must be sequenced from a single block.
Light the treads, not the well. A bright pendant in a stairwell leaves the treads in shadow, which is exactly backwards.
Choose the tread material for grip when wet, especially where the stair is near a balcony or an entrance.
What moves the estimate at this size
- Structure: an RCC stair clad in stone and a steel cantilever stair are different orders of cost.
- Tread material and edge work.
- Balustrade type, with frameless glass and brass channels at the top.
- Integrated lighting.
- Engineering and site access for heavy elements.
Questions
Staircase questions
What rise and going make a comfortable stair?
A rise of 165–180mm with a going of 275–300mm. Twice the rise plus the going should land between 600mm and 640mm — that ratio is what makes a stair feel effortless.
Are open risers safe with children?
They meet code if the gap is under 100mm so a child's head cannot pass. Below about age four many parents still fit a temporary infill.
How wide should a domestic staircase be?
900mm clear minimum, 1,000mm if it is the main flight in a villa. Below 900mm two people cannot pass and moving furniture becomes a real problem.
What is the best material for treads?
Solid timber at 40mm or stone at 30mm on a proper structure. Whatever you choose, specify a nosing with grip — polished stone treads are genuinely dangerous in socks.
