The warm shell problem: what occupiers actually inherit

Every occupier taking space in an Indian technology park signs for a warm shell. Remarkably few know, at the point of signing, exactly what that phrase covers in their specific building.

The definition is not standard

"Warm shell" is a convention, not a specification. Across the parks reviewed for this paper, the scope of what a landlord delivers varied on every one of the following:

• Whether the HVAC is delivered to the floor or only to the riser
• Whether the false ceiling grid is in place
• The provision, or absence, of a fire detection and suppression layout
• Power allocation per square foot, and whether the DG backup is on the same basis
• Washroom finishing, which is sometimes in scope and sometimes not

Why it matters commercially

The delta between a generous warm shell and a thin one runs to a meaningful share of total fit-out cost. When that delta is not priced during negotiation, it lands on the occupier's project budget six months later, after the rent has already been agreed.

A practical schedule

Before signing, ask the landlord to confirm — in the lease, not in an email — the following:

1. HVAC: tonnage, delivery point, and who owns the AHU
2. Electrical: sanctioned load per sq ft, DG backup percentage, panel location
3. Fire: detection layout, sprinkler drop provision, and the approval position with the local authority
4. Ceiling and flooring: grid, tiles, raised floor if any
5. Washrooms: count, finish level, and accessibility compliance
6. Facade: whether any modification is permitted at all

What good looks like

The strongest occupier teams treat the warm shell schedule as a commercial annexure with a rupee value attached to each line. Where a landlord will not deliver an item, that item is costed and traded against rent or the fit-out contribution.

This turns an ambiguity into a negotiation, which is where it belongs.
