Kolkata Heritage Apartment Renovation Case Study

When the Banerjee family approached Royal Decor Interior Designer, they owned a 1,450 sq ft third-floor apartment in a 1960s South Kolkata building near Rashbehari Avenue — high ceilings, teak door frames, patterned cement tiles in the passage, and a layout frozen in another era.

They wanted contemporary kitchens and wardrobes, concealed wiring, and air-conditioning without gutting the soul of the flat. This case study documents how we balanced conservation and transformation over fourteen weeks — a reference for anyone renovating Kolkata heritage stock rather than demolishing character for modular convenience.

Respecting old bones while meeting modern life — that is the art of heritage renovation.

Site conditions and constraints

Heritage apartments bring surprises: uneven floors, hidden termite damage in skirting, and society rules limiting structural changes. Load-bearing walls could not move; the wet kitchen stayed in its original corner. We surveyed with laser levels and moisture meters before any design commitment.

The client brief prioritised retaining original teak window frames (restored, not replaced), the passage tile pattern, and plaster cornices in the living room. Everything new had to complement — not compete with — these elements.

• Building age: circa 1963, cooperative society
• Scope: full interior refresh, no structural demolition
• Key challenge: electrical upgrade without surface conduit on heritage walls

Design approach: modern inside, classic outside

We chose warm white walls (Asian Paints Nilaya line), matte oak laminate for new cabinetry, and brass hardware to dialogue with existing metal latches. The TV wall used subtle fluted panels rather than high-gloss PU that would clash with aged plaster textures.

Bedroom wardrobes were built around restored teak door heights — custom modules rather than standard 7 ft boxes. Sliding mirrors faced the window wall to bounce light into a north-facing master bedroom.

Kitchen transformation within tight footprint

The 9×7 ft kitchen received a parallel layout: tall pantry on one end, hob and sink on opposite wall with quartz counter. Chimney ducting ran through a false bulkhead matching ceiling height transitions original to the flat.

BWP plywood carcasses and soft-close hardware were specified for monsoon resilience. Tile backsplash in handmade-look ceramic bridged old Kolkata aesthetic with easy-clean surfaces for daily fish and tadka cooking.

Electrical, AC, and invisible upgrades

Rewiring happened through ceiling cavities and new false ceiling zones in bathrooms only — living room wires chased minimally into plaster and patched by skilled masons colour-matched to existing walls. Split AC units placed to avoid drilling heritage window transoms.

LED cove lighting replaced tube fixtures without lowering the 11 ft living ceiling visually. Dimmers preserved evening warmth compatible with antique floor lamps the family refused to retire.

Outcome and client feedback

Handover occurred fourteen weeks after civil start, two weeks ahead of Durga Puja — the family's non-negotiable deadline for hosting. Final snag list had eleven items; all closed within five days.

Mrs Banerjee noted the flat "finally works for 2025" while guests still ask if the teak is original. That compliment is the metric we chase on heritage projects — invisible modernity, visible character.

Total project investment sat in the mid-range for South Kolkata turnkey work — proving heritage sensitivity does not require unlimited budget, only skilled trades and disciplined scope control.

Lessons for similar renovations

Photograph every wall and fitting before demolition — future disputes with societies and family members about what was original need evidence. Budget 10–15% contingency for plaster repair once old skirting comes off.

If your flat has Madras terrace roofing above, inspect for seepage before investing in premium paint below. Interiors cannot outrun unresolved building envelope problems.
