Most interior work never touches structure. But a meaningful share of Pune renovations involve removing a wall, adding a loft, moving a bathroom or loading a slab — and in those cases the difference between a competent job and a dangerous one is an assessment that costs very little relative to the risk.
Here is when you need one.
The five situations that require structural input
- Removing or opening any wall. In an RCC-framed building most internal walls are non-structural infill — but not all, and the exceptions are not visually obvious. In older load-bearing construction, which is common in central Pune, Kothrud and older Chinchwad and Aundh stock, many walls are carrying load and cannot come out without a designed replacement.
- Cutting a new opening in an existing wall, even a non-structural one, if it is large. Openings need a lintel sized for the span and the load above.
- Adding a mezzanine, loft slab or heavy platform. Anything that adds sustained load to a slab or ties into columns.
- Heavy point loads. A stone-clad feature wall, a large aquarium, a masonry island, a full-height stone counter, or a heavy pooja unit on an upper floor. Slabs are designed for a distributed load, not a concentrated one.
- Moving a bathroom or kitchen against the plumbing stack, which usually means core-cutting the slab for new drainage. Core-cutting through a slab without knowing where the reinforcement runs is one of the genuinely serious mistakes in this trade.
What you can normally do without engineering input
Standard joinery fixed to walls, false ceilings hung from the slab with proper anchors, electrical chasing within permitted depth, new tiling, replacing sanitaryware in the same position, and non-structural partitions in gypsum or glass. Most interior projects live entirely in this category.
The checks to run before any demolition
- Get the building's structural drawings where they exist. Newer societies often have them; older buildings frequently do not.
- Identify the frame. RCC-framed with infill walls, or load-bearing masonry? This single question changes everything, and in a building over roughly thirty years old it should be answered by someone qualified rather than assumed.
- Scan before you cut. Rebar scanning before core-cutting or deep chasing is inexpensive and prevents cutting reinforcement or a conduit.
- Check the society's rules. Many Pune and PCMC societies prohibit structural modification outright, or require written permission and an engineer's certificate. Doing the work first and asking later can mean reinstating it at your cost.
- Check the sanction position. Structural changes may require municipal approval. Unauthorised alteration is a real liability at resale.
The warning signs in a quotation
Be cautious of any contractor who says "that wall is not load bearing, we do it all the time" without looking at a drawing, or "we will manage the permission later." Both are common, and both put the risk on you rather than on them.
What you want instead is a written assessment naming which walls can be removed, what support is required where, and — if core-cutting is involved — a scan report before the cut.
Why we handle this in-house
Our practice was built around pairing interior curation with structural and civil engineering rather than treating them as separate trades. Practically, that means the person who draws your revised layout is working alongside the person who has to certify it, so an unbuildable idea is caught at the drawing stage rather than discovered on site with a hammer in someone's hand.
It also means one point of accountability. When a designer, a contractor and an outside consultant each own a piece of the decision, the gaps between them are exactly where problems live.
If your project involves opening up a layout, adding a loft or moving a wet area, book a free consultation and we will assess it before you commit to a design. Read more about our studio, or see our architectural and structural services.
