Other concepts explored in this chapter include
plottage (from assemblage) and size regression (based on economies of scale, the price per unit paid decreases).
Plottage can increase the value of a property if the adjacent area allows for further extension of the primary residence or serving the dominant site by increasing the garden or landscaped area, or providing additional parking, especially in a high-built environments.
Plottage is the increment of value created when two or more sites are combined to produce greater utility.

The compulsory factors include
plottage area, total floor area, land ratio, floor area ratio, no.
Brown later became a partner of President Theodore Roosevelt's brother-in-law, Douglas Robbinson, who led the firm into
plottage and site assemblage, and was instrumental in developing the city's insurance district around William and John Streets.
Think of the additional increments in value possible that may arise from changes in highest and best use and factors of cost beyond the purchase price of the component parcels; think of the likelihood of assemblage value often resulting in
plottage; i.e., the increment of value created when two or more sites are combined to produce greater utility.
Some commentators believe the corridor factor multiple (30) is a measure of
plottage, an incremental increase in value created by combining the separate land parcels to create a corridor.
Among these concepts are assemblage,
plottage, multiple uses, connecting end points, limited market property, and the larger parcel.
plottage can be a negative factor when the tract under appraisal is larger than the optimum configuration for the prevailing pattern of utilization.
Furthermore, it can often be contended that
plottage value derives from an easily envisioned assemblage.
