Top-tier classification of office space, distinguished by quality, location, age, and amenitisation.
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.
270 Park Avenue in Manhattan and 22 Bishopsgate in London are both Class A.
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.
