Renovation budget for a 175 m² apartment in Delhi?

Before I ask contractors for firm quotations, I need to decide how much of the ₹5,260,000 budget can safely be committed to finishes. The apartment is 175 m² in Delhi, and the planned work covers the kitchen, bathrooms, flooring, paint, electrical checks and moderate energy improvements rather than an extension.

The unknowns are more important to me than premium materials. For example, moisture behind a bathroom wall could change both the sequence and the cost. What should be inspected for structural or waterproofing problems, and which items should remain provisional until access is opened up? I would also like to know which materials commonly need to be selected early because of lead times.
 
I would initially reserve 15–20%, then reduce it only after opening up the main unknowns. Ask contractors to list exclusions in writing: rewiring beyond visible defects, concealed plumbing replacement, waterproofing repairs, floor levelling, debris removal, access restrictions and protection of common areas. Also separate provisional allowances from fixed-price work so the apparent total is meaningful.
 
How old is the apartment, and can plumbing risers or electrical distribution points be inspected without major demolition? Those details matter more than the floor area alone. I’d also ask whether there are existing moisture marks around bathrooms, external walls or service shafts, and whether occupied flats above or below limit noisy-work hours or access.
 
I’d be cautious about assuming “no structural work” means no structural risk. Removing flooring, changing bathroom layouts or chasing walls for services can reveal cracks or unsuitable substrates even when no extension is planned. Before setting the contingency, confirm which walls and slabs must remain untouched and whether any proposed service routes need building approval. Delhi requirements can vary by building and authority, so that timing should not be guessed.
 
Agreed on distinguishing intended structural work from structural discoveries. I would not spend the contingency on upgraded finishes before demolition is complete. One useful contractor question is: “What findings would trigger a variation, and how will labour, materials and delay be priced?” If the answer is vague, the contingency percentage alone will not protect the budget.
 
Sequence the investigation around what can stop later trades: moisture and plumbing first, then electrical capacity and routes, then floor levels and substrates. After that, lock kitchen and bathroom layouts before ordering materials. Long-lead items should be identified early, but avoid ordering dimensions that depend on unfinished walls or floors. The programme should also show approval time, building access, debris movement and drying time—not just installation days.
 
I’d turn the ₹5,260,000 into three columns: defined work, allowances for unresolved items, and contingency for genuine surprises. Then request the same breakdown from each contractor rather than comparing headline totals. The pre-contract questions should cover plumbing access, moisture testing, electrical replacement boundaries, floor preparation, exclusions, material lead times, permit responsibility and who pays when hidden conditions alter the sequence.
