Inswept means that a component makes an inward-directed, hollow (concave) curve. The Dutch term “ingezwenkt” comes from “swinging” — changing direction or bending — and describes a line or surface that curves inward. The opposite is “outswept”: an outward-directed, bulging (convex) curve.
Where does it occur?
Inswept shapes are typical of the graceful gables of Dutch architecture, especially on historic canal houses:
- Neck gables and bell gables — the gable crowning makes a hollow curve that flows smoothly into the top
- Claw pieces — the decorative pieces flanking the gable top are often made inswept
- Buttresses and transitions — where a vertical surface narrows upward with a hollow curve
Application
- Historic facades — the alternation of inswept and outswept lines gives a facade a lively, articulated silhouette
- Restoration — when repairing monumental facades the original curvature must be followed exactly
- Ornamentation — mouldings and scrolls in Baroque and Renaissance make much use of inswept shapes
Points to note
- An inswept gable termination requires skilled bricklaying and cutting, because each course offsets slightly
- The hollow shape can hold water; good drainage and lead flashing are important
