Design Ideas

Distinctive Designs: Polygonal and Specialty Shape Windows

Considering the full possibilities of shape and placement, unique architectural looks and styles can be achieved with specialty shape windows. 

Windows, traditionally, are approached as rectangular openings, steadily inviting views and natural light into a home. This uniform shape, however, can be creatively adjusted to the architectural needs of a home’s design, producing impressive facades, inspired interiors, and spaces that feel wholly unique. 

Discover the many ways these exceptional dwellings applied custom Marvin specialty shape windows to their design. 

The Modern Dwelling Among Wildflower Fields

Hidden amidst rolling fields, flora, and pine trees, this mid-century modern escape welcomes the natural foliage with abundant views. Constructed to showcase the abundant wildlife and landscape, this unique dwelling demanded a native plant specialist to ensure minimal interference with the tranquil surroundings.

Utilizing polygonal transom windows that follow the angle of the flat roof architecture, this one-of-a-kind home subtly extends the range of view from within, complementing the naturally hilly terrain. Adding unique transom window shapes brought an illuminating, yet reserved framing to the home’s surroundings, making for an effective space that authentically reflects the world around it.

Bayview Home: Framing a Coastal Vista

A California coastal home with a picturesque vista outside its front door was in dire need of a remodel. Affected by years of humidity, high winds, and harsh sunlight, the home gave architect Scott Landry an opportunity to expand the view from within. With polygonal direct glaze windows uniquely shaped to the contemporary architecture of the home, the renovated space added new depth and expansive light to the inside. 

Focusing on how the exterior view elevated the character of the whole home, the window design was able to play off the creativity of the structure. Distinguishing the dwelling with an architecturally bold and prominent façade.  

A Cabin Illuminated in the Woods

Surrounded by trees, this A-frame cabin opened up its dimly lit interior with floor to ceiling windows. The Scandinavian-inspired facade was defined by its steep slanted roof, creating a welcoming and cozy look. Custom triangular-shaped windows that matched the angle of the structure were installed to maximize the view and brighten up the indoor space with nearly a full wall of glass. 

With windows that embraced the design of the architectural exterior, this cabin took on new life to expose the outdoors with untraditional angles, bringing an elevated level of comfort for those inside. 

Floor to Ceiling Comfort in Deer Hill

Contemporary homes with spacious footprints like this avant-garde residence overlooking a nature preserve require expansive windows to visually connect the home design throughout the interior. Custom-shaped windows help provide an uninterrupted abundance of light into the shared spaces, filling them with natural ambience that reaches all the way up the vaulted ceilings. 

Designed with such significant floor space, the windows were trusted to naturally illuminate the area. With the window height scaled to match the spacious interior, there was less need to artificially light the variety of rooms and shared spaces, creating a harmonious feeling between architecture and inhabitant.

Marvin makes custom-shaped and polygonal windows to enable greater possibilities in homebuilding and renovation. Unique windows add personality and boldness, making for an excellent addition for various architectural styles.
