Part 1 of this series focuses on classic and traditional dormers: from the 17th-century Dutch roof houses to the elaborate variants of 19th-century townhouses. These examples show how craftsmanship, material choice and proportion together define the appearance of a dormer.
Dutch roof houses (17th–18th century)
The earliest dormers are small roof houses with a short gable roof, often crowned by a curl or simple pediment. Features:
- Wooden window frames with small panes of blown glass
- Lead flashing around the frame
- Slate or tile covering on the cap
- Wooden cheeks with profiled trims
Bell-shaped and ornate variants
In the 18th century, ornate variants emerged with bell-shaped or stepped gables on top of the dormer. Often combined with:
- A curved or segmental pediment
- Carved decoration of shells, festoons or scrollwork
- Gilded or polychrome details
19th-century townhouse dormers
In neoclassical and eclectic houses, dormers were monumental:
- Strict profiled trim around the frame
- Triangular or segmental pediments
- Pilasters on either side of the window
- Cast zinc ornaments as a crowning element
Farmhouse dormers
In rural areas, dormers stayed functional and simple:
- Small wooden dormers for hay or storage hatches
- Hoist hatches instead of windows
- Untreated or dark-stained wood
Application
In restoration of listed buildings, these classical references are often used. Heritage committees value execution that matches the original character of the building. Before installing a traditional dormer, it is wise to consult archival photographs or old drawings.
