Joan Aug 08, 2026

Nestled within the grandeur of Glensheen Mansion, a historic home in Duluth, Minnesota, lies a truly unique and captivating space - the Sunroom. This architectural gem offers a harmonious blend of opulence, functionality, and natural beauty, making it a standout feature of this 27-room estate. The Sunroom, with its magnificent windows and delightful greenery, is not just an addition to the mansion; it's an experience, a refuge, and a testament to Glensheen's commitment to preserving its rich history while embracing modern charm.

To appreciate the Sunroom fully, one must understand its role in the evolution of Glensheen Mansion. Constructed between 1906 and 1908 by Chester Congdon, a prominent attorney and mine owner, Glensheen was designed to showcase the family's wealth and social standing. The Sunroom, added in the early 1920s by Chester's son, Edward, was a significant departure from the classic, heavy architecture that characterized the main house. Instead, it introduced a light, airy space that reflected the Art Deco influences sweeping through Europe and the United States at the time.

The Architecture and Design of Glensheen's Sunroom

The design of the Sunroom is a symphony of lines, curves, and proportions that create a sense of balance and harmony. The room stretches 30 feet by 12 feet, with ceilings that soar to 16 feet at their highest point, flooding the space with natural light.

The Sunroom's open floor plan encourages movement and fluidity, mirroring the changing seasons outside. A central courtyard bisects the room, housing an impressive array of plants that range from vibrant daylilies to towering banana trees. This lush oasis not only adds a touch of nature to the space but also works to regulate the room's temperature, a feature that would have appealed to Glensheen's original inhabitants.

The Art Deco Influence in the Sunroom

Art Deco, a design movement that flourished in the 1920s and 1930s, is characterized by its bold geometric shapes, luxurious materials, and incorporation of modern technologies. The Sunroom exemplifies these characteristics, from its streamlined design to its innovative use of glass and steel. The room's arched doorway, for example, is a classic art deco element called a 'Solomon Dounce' arch, named after an early 20th-century architect who popularized the design. This arch, with its striking symmetry and elegant lines, transforms what could have been a mundane entryway into a feature that captivates and intrigues.

Another notable art deco element in the Sunroom is the series of diamond-shaped windows set into the courtyard wall. These windows, made possible by advancements in glass technology, allow for an abundance of light while evoking the bold geometric patterns popular in art deco design. These innovative design choices were, and continue to be, a testament to Glensheen's commitment to embracing modernism while preserving its rich historical legacy.

The Sunroom signifies a transition in Glensheen's architectural history, marking the shift from the grand, heavy architecture of the early 20th century to the lighter, more open spaces that would become prevalent in the decades that followed. This evolution is a reflection of the changing societal norms and aesthetic sensibilities of the time. As families became more informal and the pace of life quickened, homes began to change as well, with an emphasis on functionality, openness, and indoor-outdoor living.

The Sunroom, with its harmonious blend of natural light, lush greenery, and art deco design, embodies this new ethos. It's a space that invites contemplation and offers a retreat from the world, much as it would have done for the Congdon family who first inhabited it. Today, visitors to Glensheen Mansion can still take comfort in the Sunroom, finding solace in its tranquility and marveling at its enduring design.

The Sunroom's Legacy: Preservation and Adaptation

Glensheen Mansion, including its unique Sunroom, was donated to the University of Minnesota Duluth in the 1970s. Since then, the estate has been meticulously preserved as a historic house museum, offering visitors a glimpse into the life and times of the Congdon family. The Sunroom, in particular, has been adapted to serve as a flexible event space, hosting everything from weddings to corporate events.

Yet, despite these changes, the Sunroom remains a stunning example of its art deco roots, a fact made possible by the dedication of Glensheen's conservators and curators. The room's original finishings, from the elegant chrome hardware to the warm, gleaming wood floors, have been carefully restored and maintained, ensuring that the Sunroom's original beauty continues to inspire awe and admiration.
