Assemblage.

Explanation:

In Real estate, putting together two or more parcels of land to make a large piece is called assemblage. The main purpose of assemblage is to increase the price of parcels of land by combining them together rather than selling them individually as a single unit.

For instance, a real estate agent may purchase two (5) parcels of land each worth $50,000 (2 × $50,000). When he assembles them, the new single parcel of land is worth $150,000.
