Architectural Working Drawings — Elevation sheets generally include four primary exterior views of a simple rectangular building: front (primary facade), right side, back (rear), and left side, each dimensioned and annotated for materials and levels.

Introduction / Context:
Exterior elevations convey appearance, massing, materials, openings, and vertical datums such as finished floor and roof heights. For most straightforward buildings, four orthographic views—front, right, rear, and left—provide a complete wrap-around understanding of the envelope for construction and permitting.

Given Data / Assumptions:

• A simple plan geometry without complex curves or many wings.
• Standard orthographic projection for clarity and dimensioning.
• Need to show materials, fenestration, roof slopes, and heights.

Concept / Approach:
Providing all sides ensures no façade is left undescribed, avoiding ambiguity about window placement, siding transitions, or eave details. While more complex forms may require additional partial elevations, a baseline set includes the four cardinal views with consistent level references and material notes.

Step-by-Step Solution:
1) Establish level datums (e.g., ground line, finished floors, eaves, and ridges).2) Draw the front elevation as the primary reference for style and entry.3) Add right and left elevations, aligning windows and eaves to the same datums.4) Complete the rear elevation, confirming door/window types and deck interfaces.

Verification / Alternative check:
Compare the set against the floor plan and roof plan: doors, windows, and roof lines should reconcile across all four elevations, confirming completeness.

Why Other Options Are Wrong:
Only showing the front ignores code and construction needs; sections do not replace elevations for exterior cladding; collapsing both sides into one view omits unique conditions like grade steps or chimney chases.

Common Pitfalls:
Inconsistent window head heights across façades; missing materials legends; forgetting to show downspouts and vent terminations that affect coordination.
