In this article, we will discuss 8 of the architectural styles that you are likely to find in Boulder, Colorado. By taking the time to consider some of the many popular options that are currently available, you’ll be one step closer to designing the home of your dreams.

1. Ranch Style Architecture

Ranch style architecture was exceptionally popular in the 1960s and 1970s, which is when Boulder experienced a major wave of population growth. These homes are characterized by their wide, often open floor plans and are typically one story tall. They offer functional floor plans and often feature windows throughout the home.

Ranch style homes often have features that were unique to the era they were built in, such as sunken living rooms, family-oriented layouts, and informal room designations. Another popular style found in Boulder—one that was derived from the once-popular ranch—is the split-level home. These homes combine the flat, natural look of the ranch while also increasing the available living space.

2. Victorian Architecture

Victorian architecture was common during the Victorian era, which existed right around the time Colorado officially became a state (1876). Some of Boulder’s oldest homes have elements of the very flamboyant Victorian style, including the Arnett-Fullen House, located on Pearl Street.

Some of the most notable features of Victorian homes include their large frame, multi-faceted roofs, decorative trim, and occasional towers. While these homes do have a notoriously “haunted” appearance, well-maintained Victorians are among the most valuable homes on the market. For this reason, many of these properties have historic protections.

3. Mid-Century Modern Architecture

The mid-century modern movement was a significant aesthetic movement that lasted from about the 1940s to the 1970s. These homes characteristically reject styles used in earlier years in favor of designs that are simpler and more oriented for everyday living.

Perhaps the most defining characteristic of mid-century modern homes is their open floor plans. Rather than keeping living spaces separated, mid-century designers wanted spaces (other than bedrooms and bathrooms) to blend together. Additionally, these homes often emphasize the importance of blending indoor and outdoor living spaces. As a result, floor-to-ceiling windows, sunrooms, and easy access to the backyard are all commonly found.

4. Craftsman Style Architecture

During the arts and crafts movement of the 1920s and 1930s, the craftsman bungalow emerged as one of the most popular architectural styles for middle-class Americans. Made of wood and stone or brick, many of the features on these homes were designed by hand (by craft), allowing them to have a unique charm worthy of appreciation.

Craftsman homes are characterized by wide, open front porches. Wide roofs, symmetry, sophisticated ceilings, and intricate design features also contribute to these homes’ unquestionable character. While the craftsman bungalow peaked in popularity long ago, this style has recently experienced a major revival.

5. Brutalist Architecture

Brutalist architecture—as the name implies—is often utilized on a large scale, featuring impressive and even overwhelming features. These buildings typically have relatively few windows, strong structural features, and often include large amounts of concrete.

On the University of Colorado’s campus, the Engineering Center and the Coors Events Center are both popular examples of American brutalism. The National Center for Atmospheric Research—one of the most recognizable buildings in the city—is yet another sturdy example.

6. Organic Architecture

As a city known for its thriving outdoor scene, it is no surprise that natural or “organic” architecture is especially common in Boulder. The goal of organic architecture is to blend the home into its natural environment. Many of today’s organic architects are inspired by the earlier works of Frank Lloyd Wright.

Gardens, modest stone and wood features, windows, and even mirrors can help a home feel a bit more naturally integrated. In Boulder, understanding the relationship each home has to the stunning Flatirons is a must. Additionally, many architects in the organic space also focus on sustainability.

7. Contemporary Architecture

Architecture is an evolving discipline and each year, there are new features that contemporary architects might use. Some of the most popular features of contemporary residential architecture include the generous use of glass, asymmetrical features, repurposed building materials, and smart home technology. Outdoor lighting, open floor plans, and convertible living spaces are also very popular (especially in the work from home era).

8. Mixed Architecture

Lastly, you’ll find that plenty of the buildings in Boulder have architectural features that cannot easily be categorized. This is because, in many cases, these homes were developed in phases, rather than all at once. Combining features from two styles that would otherwise seem to be contradictory—such as Victorian and Contemporary—can help you create a living space that is truly unique to you.


If you were to randomly select ten homes in the city of Boulder, you very well might find ten entirely different architectural styles. Boulder architects provide architecture, as a whole, is as diverse as it is iconic. With many architects available to choose from in and near the city of Boulder, you’re almost certain to find a design style that works for you.
