Which term refers to an increase in overall value from the assembly of multiple plots?

The concept of plottage refers specifically to the increase in value obtained by combining two or more adjacent parcels of land into a single larger parcel. This increase in value occurs because the larger property can be developed in a way that is more beneficial than if each parcel were developed separately, such as improved access, a larger footprint for buildings, and more efficient site planning.

In the context of real estate and land use, plottage is important for maximizing the economic potential of properties. By understanding plottage, real estate developers and investors can make strategic decisions about purchasing multiple adjacent properties, as they can often command a higher value as a collective unit than individually.

Amalgamation relates more to the combining of companies than land parcels. Assemblage refers to the process of gathering those parcels together but does not specifically address the increase in value. Subdivision involves dividing a larger parcel into smaller lots, which can be valuable in its own right but does not relate to increasing value from assembly.
