# Main Building (99)

> Source pattern from the abridged `apl-md` corpus. Use as a design reference and constraint seed; do not treat as commercial-clean training data.

### Problem
>A complex of buildings with no center is like a person without a head.

### Solution
>For any collection of buildings, decide which building in the group houses the most essential function—which building is the soul of the group, as a human institution. Then form this building as the main building, with a central position, higher roof.
>Even if the building complex is so dense that it is a single building, build the main part of it higher and more prominent than the rest, so that the eye goes immediately to the part which is the most important.

### Related Patterns
... once you have decided more or less how people will move around within the [[Building Complex (95)]], and roughly how high the buildings will be - [[Number of Stories (96)]] - it is time to try and find the natural heart or center of the building complex, to help complete its [[Circulation Realms (98)]].

Build all the main paths tangent to the main building, in arcades or glazed corridors, with a direct view into its main functions - [[Common Areas at the Heart (129)]]. Make the roof cascade down from the high roof over the main building to lower roofs over the smaller buildings - [[Cascade of Roofs (116)]]. And for the load bearing structure, engineering, and construction, begin with [[Structure Follows Social Spaces (205)]] ...
