Prompt
Hand-drawn architectural concept sketch of {{building}}, located in {{site}}. Loose but confident black ink lines on {{paper}}, with construction lines and slight overshoots at the corners, two-point perspective {{viewpoint}}. Light watercolor washes only on key areas: {{accents}}, leaving most of the paper white. Human figures, trees and a car drawn as quick gestures for scale. Shadows suggested with hatching. Composition with the building slightly off-center and a vignette that fades out toward the edges. Style of an architect's design competition sketchbook, expressive and easy to read. No text, no annotations, no watermark.How to use it
- Describe the building by massing and materials ("three-story block with a timber screen and a glazed ground floor"), not just by its function.
- Limit color accents to two elements so the sketch does not look like a render.
- If the result is too clean, ask for more construction lines and imperfect strokes.
- Proportions are approximate: do not use it as a technical drawing.
Usage example
Building: a neighborhood library with a sawtooth roof and brick facade · Site: a tree-lined square in Portland · Paper: kraft paper · Viewpoint: eye level from a street corner · Accents: warm brick and tree greens.

Frequently asked questions
Why a sketch instead of a render?
A sketch communicates an idea without locking in details that are not decided yet. It works well in early design phases, in client meetings or to give a portfolio a more hand-crafted feel.
Can I start from my own photo or 3D model?
Yes, if your tool supports image references or structure control. The sketch will then follow your real massing and only change the drawing style.
