Floor plate
One floor of a building, considered as a single horizontal surface: its outline, the position of the core inside it, and the space left over between the two. The word describes the floor as a shape rather than as a set of rooms.
Fit-out changes. Partitions come and go with each tenancy, and the room names on a plan often belong to a company that left years ago. The plate is what stays: the envelope, the structure, the lift and stair core, the columns. It is the part of the floor a landlord is actually letting.
What a reader looks for
Three properties do most of the work. The shape of the outline decides whether a tenant can lay out a floor in one arrangement or is forced around a corner. The position of the core decides whether the usable space is one field or several leftovers. And the distance from the core to the glass decides how much of the floor sits near daylight.
Columns matter for the same reason. A column grid is invisible in a schedule of areas and unavoidable in a desk layout, which is why anyone planning an occupancy wants to see where the columns land before they want to see a photograph of the lobby.
Why it decides the enquiry
Tenants take floors, or parts of floors, and the question they are asking is whether their organisation fits into this shape. A brochure describing amenity does not answer that. A plate that can be read does.
How StudiO reads a plate
Extraction works at plate level. The exterior envelope, the core and the partitions are each measured per wall segment and typed by role, and columns are detected with the evidence that found them. What comes back shows the shape of the floor with the structure that constrains it, in a form a person can move through rather than interpret.
