Short definition

Top-tier classification of office space, distinguished by quality, location, age, and amenitisation.

Full definition

Class A is a market-determined classification — not a regulatory standard. Buildings are typically Class A if they were recently built (or recently repositioned), in the most prestigious submarkets, with institutional-grade systems, MEP, and ESG credentials. The classification is locally calibrated: a Class A building in Mumbai is a different specification from a Class A building in Manhattan, but both occupy the top tier of their respective markets.

Example

270 Park Avenue in Manhattan and 22 Bishopsgate in London are both Class A.

Why this matters for Class A leasing

Class A is part of the asset class vocabulary that institutional Class A occupiers, landlords, and advisers use across Global markets. Understanding it correctly affects how you read lease documents, model occupancy economics, and benchmark deal terms across cities. Class A Atlas tracks regional variation alongside the global standard so cross-border occupiers can translate quickly.
