An elevation is just what a slice of cells looks like from the outside.
How It Shapes Development
Elevations are side views of cells because a building elevation is the projection of the building's cellular stack onto a vertical plane. What appears in the elevation — window openings, floor lines, parapet height — is a direct consequence of the cell arrangement behind the facade. Window locations are where the cells need light. Floor lines are where one cell ends and the next begins. The facade is not applied to the building; it is generated by the cells behind it. A facade that contradicts the cell arrangement requires expensive structural or spatial gymnastics to achieve.
Floor-to-floor height is the dominant variable in elevation proportion. A 10-foot floor-to-floor produces a different facade rhythm than a 14-foot floor-to-floor. Residential construction typically runs 9–10 feet floor-to-floor. Office runs 13–15 feet to accommodate ceiling plenum, raised flooring, and ductwork. Hotel runs 10–11 feet. Each building type produces a characteristic horizontal banding in the elevation because the floor-to-floor sets the vertical module. You can identify the building type from the elevation proportion before reading a label.
Punched window elevations are residential. Curtain wall elevations are commercial. This is not an aesthetic preference — it is a structural and thermal consequence of cell type. Residential cells have solid walls with punched openings because the structural system is typically wood or concrete with bearing walls, and thermal performance requirements for residential envelope are higher. Commercial cells have curtain wall glazing because the structural system is typically a moment frame or core-and-outrigger that doesn't require the facade to carry load, and the tenant mix demands flexible interior layouts with maximum natural light. The elevation type is downstream of the structural type, which is downstream of the cell type.
Setback requirements and height limits read directly in elevation. A zoning code that requires a 10-foot setback above the 6th floor produces a step in the elevation at that level. A building that reaches its FAR limit before its height limit stops adding floors, and the parapet line falls wherever the floor count hits the FAR ceiling. The elevation is a diagram of the zoning constraints as much as a diagram of the architecture. Read the elevation and you can reconstruct most of the zoning envelope that produced it.
