master plan architect
A company which designs the basic plan for a large development, including general guidelines for buildings within it.
Planning companies which design a building's or project's surroundings including the arrangement of landscape elements, roads, and access ways. At times they set guidelines for a building's envelope or general design, but this role does not concern the actual building design.
The role arranges the wider setting, including landscape, roads, and access. It can establish a building envelope or general design guidelines without designing the building itself.
Detailed responsibility for the actual building belongs to a different architectural role. A master-plan architect is identified by planning the surrounding development and its arrangement.
