Mastering Dormer Design: Step-by-Step Plan Drawing Tutorial

By David TaylorMarch 10, 2026

Ever wondered how to add charm and character to your architectural designs? Dormers are a fantastic way to achieve this, providing additional space and enhancing the aesthetic appeal of your structures. If you're an architect, draftsperson, or simply an aspiring artist, knowing how to draw a dormer in plan is an invaluable skill. Let's dive into this comprehensive guide to help you master this technique.

Before we begin, it's essential to understand what a dormer is. A dormer is a vertical projection from a sloping roof, often containing a window, that allows for increased headroom within the structure and adds visual interest to the exterior. Now that we're on the same page let's start drawing!

Understanding Dormer Types

Before putting pencil to paper, it's crucial to familiarize yourself with the different types of dormers. Each type has unique characteristics that will influence your drawing approach.

1. **Gable-fronted Dormer**: This is the most common type, featuring a triangular roof that matches the main roof's pitch. It projects perpendicularly from the main roof.

Gable-fronted Dormer Details

To draw a gable-fronted dormer, start by sketching the rectangle that represents the dormer's floor. Then, draw the gable roof, ensuring it matches the main roof's pitch. Add the window and any additional details, such as trim or shingles.

Remember, the gable roof is composed of two equal triangles. The height of the dormer (from the ridge to the eaves) should be half the width of the dormer floor. This will ensure your gable roof is correctly proportioned.

Gable-fronted Dormer Variations

Gable-fronted dormers can have variations in their roof design, such as hip roofs or flat roofs. To draw these, follow the same initial steps but adjust the roof shape accordingly.

For a hip roof dormer, draw four equal sides sloping downwards from the ridge. For a flat roof dormer, simply draw a rectangle with the same dimensions as the dormer floor, but without the gable ends.
