What Is a Dormer? Styles, Uses & Design

June 21, 2025

As homeowners continue to explore ways to maximize space and elevate their home's aesthetics, the dormer stands out as a popular and versatile architectural feature. Dormers not only enhance the visual appeal of a roofline but also provide valuable additional space, often transforming an attic into a functional living area. If you want to add a dormer to your home, partnering with professionals like Hoegler & Kren Builders, who understand both the technical and aesthetic aspects of design is key.


In this article, we’ll explore what a dormer is,  the various dormer window types, the different dormer styles, and factors like dormer addition cost to help you make an effective decision.


What Is a Dormer?

 Dormer designs, styles, and types

A dormer is a structure that projects from a sloping roof, typically containing a window. Dormers are used to create additional space and light on an upper level, especially in areas with pitched roofs, such as attics or lofts. Not only do they add visual interest and architectural charm, but they also open up usable space in otherwise underutilized areas of the home.


Dormers come in various designs, each suited to different types of homes, and can be installed for a variety of reasons, such as creating extra headroom or enhancing curb appeal. Whether you're looking to upgrade your attic or add charm to your home's exterior, a dormer is a great way to achieve both.


Different Dormer Windows Types 


There are several dormer window types to choose from, depending on the style you want for your home. Each type offers a different function and aesthetic, so understanding the differences will help you choose the best option.


Gable Dormer

Dormer Windows Types

The gable dormer is one of the most common and traditional types. It features a triangular roof with two sloping sides, giving it a classic look that works well on almost any type of home. The gable dormer is particularly effective for creating additional headspace, especially when added to an attic.


Hipped Dormer

Dormer Windows Types

 A hip dormer has a roof that slopes in four directions, creating a pyramid-like shape. This type of dormer offers a more sophisticated look and works well in homes with hip roofs, where all sides slope downward. Hip dormers are often used to maintain the balance and symmetry of the roofline.


Shed Dormer

Dormer Windows Types

The shed dormer features a single, flat roof that slopes in one direction. This style is often used to create more horizontal space, making it ideal for modern or minimalist designs. Shed dormers are commonly seen in contemporary homes and can be less expensive to build compared to other dormer types.


Mansard Dormer

Dormer Windows Types

 A mansard dormer is designed with a double-sloped roof, similar to the roof style of a Mansard roof. This type of dormer adds a touch of elegance and is perfect for homes that want to reflect a French architectural style. Mansard dormers are great for creating extra floor space and headroom.


Eyebrow Dormer

Dormer Styles: Eyebrow Dormer

 The eyebrow dormer has a subtle, curved roof that creates a gentle arch. This style is perfect for homes looking to achieve a more organic, soft appearance. Eyebrow dormers are often used in homes with unique or artistic designs.


Dormer Styles to Complement Your Home

 Dormer Styles to Complement Your Home

Once you’ve selected a dormer window type, you’ll need to consider the overall dormer style that best fits your home’s aesthetic. Here are a few options to inspire your design:


Traditional Dormer Styles


Traditional dormers, such as gable dormers or hipped dormers, tend to complement colonial, Cape Cod, and other classic architectural styles. These dormers feature symmetrical lines and a timeless design, making them a popular choice for older homes.


Modern Dormer Designs


For contemporary homes, shed dormers or flat-roof dormers are ideal. These styles offer a minimalist approach with clean lines and subtle curves. Modern dormers are often incorporated into homes with flat roofs, urban houses, or sleek, modern designs.


Rustic Dormers


Rustic dormers are perfect for homes with a country or cottage feel. Wooden dormers with natural finishes and rustic details enhance the charm of a log cabin, farmhouse, or cottage-style home. This style often pairs well with dormers that feature large, functional windows that bring in plenty of light.


Victorian Dormer Styles


Homes with Victorian architecture often feature ornate and elaborate dormers, such as turret dormers or Mansard dormers. These designs bring a sense of grandeur and uniqueness, with intricate details that stand out in a dramatic way.


Benefits of Adding a Dormer to a House

Adding a dormer to your home comes with several advantages, both functional and aesthetic:


Increased Living Space


A dormer addition is an excellent way to add usable space to the upper levels of your home, especially in areas like attics or lofts. This added space can be transformed into extra bedrooms, home offices, or storage.


Enhanced Natural Light


Dormers are designed with windows, which means they allow more natural light into the upper floors of your home. This can make your attic or top floor feel much brighter and more welcoming.


Improved Curb Appeal


Dormers can dramatically enhance the appearance of your home. Whether you opt for a traditional gable dormer or a modern shed dormer, this architectural feature adds character and charm that improves your home’s curb appeal.


Increased Property Value


By adding a dormer to your home, you increase its overall livable space, which could raise the property’s market value. A well-designed dormer can make your home more attractive to prospective buyers, particularly in homes where space is at a premium.


What Does a Dormer Addition Cost?


The dormer addition cost can vary significantly based on the type, size, and complexity of the design. The total price will depend on several factors, including the materials used, the labor involved, and whether the dormer is being added to an existing structure or built as part of a new construction.


Other factors that affect the cost include:


  • The type of roof (steep or flat)
  • The dormer size (single or multi-window)
  • Your location and local building codes
  • Whether you need structural changes or additional plumbing/electrical work

It’s always best to consult with a professional builder to get an accurate estimate tailored to your specific needs and home.
