Renovation contingency for a 60 m² Bengaluru coastal home

[luca.east]

I can either reserve a large part of the renovation fund for hidden defects or allocate more of it to the known work, and neither option feels comfortable without better information. This is a 60 m² coastal-style home in Bengaluru priced at ₹52,190,000, with ₹12,470,000 provisionally set aside for renovation.

The scope currently covers the kitchen, bathrooms, floors, painting, electrical checks and moderate energy improvements. There is no extension planned, although I realise opening walls or repairing damaged areas could still reveal structural work. Finishes can be postponed; unsafe wiring, leaks or drainage faults cannot.

What size reserve would be sensible before inspections, and where would targeted opening-up be most useful? I would particularly want the surveyor or contractor to examine moisture, electrical condition, drainage and access to concealed plumbing. The meaning of “coastal” also needs checking, as actual salt or moisture exposure would change the risk.

Until the electrical and plumbing condition is clearer, I would reserve roughly 15–20% rather than treating every rupee as available for the listed work. Keep that reserve separate from finish upgrades. Ask for inspection of the distribution board, wiring routes, water pressure, drainage and concealed pipe access before fixing the kitchen and bathroom layouts.

What does “coastal home” mean here: a design description, coastal materials, or known salt and moisture exposure despite the Bengaluru location? Also, how old are the wet areas, and is the home occupied? Those answers affect whether non-destructive inspection is enough or whether you should budget for selective opening of walls and floors.

I wouldn’t choose the contingency percentage before normalising the contractor scope. ₹12,470,000 is substantial for 60 m², but it can still be misleading if cabinetry, sanitary fittings, rewiring, waterproofing repairs, debris removal or tax sit outside the quote.

Request quantities and explicit exclusions, not just room totals. Two quotations can show the same headline while assigning hidden-condition risk very differently.

Sequence it from causes to finishes: moisture investigation and selective opening first, then electrical and plumbing decisions, followed by bathroom waterproofing and only later flooring, cabinetry and paint. Otherwise a leak discovered after installation can undo several completed trades. Photograph exposed services and record their routes before walls or floors are closed.

Contractor questions I’d add: Who pays if concealed pipes are unusable? Does electrical work include replacement or only testing? Are wall repairs after service access included? What assumptions were made about working hours, storage, waste removal and access? Which materials require deposits, and can equivalent locally available items be substituted if lead times slip?

 

[JaeChase]

One caveat to that last point: don’t order everything early merely to beat lead times. Fixed-dimension items can become expensive mistakes if moisture repairs or service routes change the room geometry. Identify long-lead materials now, but release final orders only after opening-up work and confirmed measurements. Any approval or permit timing should be checked locally before locking the programme.

 

[tradeTheWall]

“No extension” doesn’t necessarily mean “no structural work.” Ask the surveyor to distinguish cosmetic cracks from movement, note any altered walls or oversized openings, and inspect areas around wet rooms and balconies for deterioration. You need not assume a major defect, but the contract should explain what happens if structural repair is uncovered rather than silently excluding it.

The ideal outcome is to agree the essential scope before work begins, but concealed services and the possibility of structural repair make that difficult. Even without an extension, a crack, altered opening or deteriorated wet-room area can turn an apparently cosmetic item into something that affects the sequence and cost.

I would commission moisture mapping, an electrical inspection, plumbing and drainage checks, measured drawings, and a few carefully chosen openings around wet services. Use the findings to divide the scope into required repairs, planned improvements and finishes that can wait. Keep the contingency separate from the contractor’s working allowance, with any release tied to a recorded variation. That also reduces the chance of the reserve being absorbed by nicer finishes before the hidden work is understood.
