When searching for an idyllic place to settle down in the cloudy city of Chicago, Illinois, a couple of newlyweds were lured by a newly developed industrial-modern penthouse. With a suburban backdrop where outdoor space is scarce, the couple was immediately drawn to the unit’s expansive terrace—the size of a small apartment—that offered plenty of outdoor space for enjoying the short warmer days of Summer. Connecting the indoor and outdoor spaces are a set of strategically placed NanaWall accordion glass walls that maximize space, and natural light, and facilitate transitions inside and out.

A Custom Creative Abode with Accordion Glass Walls

The multifamily building was still in the process of development when the couple made a bid on it, and because of this, they were able to have a substantial influence on the unit’s overall design. Working with the industrial touch of what local architecture firm Booth Hansen, had applied to the structure, the homeowners sought to create something “warmer and smoother.” Having previously worked with designers Tom Riker and James Dolenc, the couple called upon them once again to personalize their new home. The duo, alongside local designer Lauren Craig, transformed the once stark penthouse into a sophisticated living space accentuated by various structural focal points—like the staircase's handcrafted wooden railing and the multi-pendant crystal chandelier suspended above.

Optimizing Natural Light with Floor to Ceiling Glass Walls  

Every unit in the building was designed with tall windows to capitalize on the sky-high views of the city and to maximize the amount of natural light flushing interiors. The couple’s vibrant art collection that decorates each room, reflects upon the bold fabrics and décor pieces throughout the home—standing out amidst the softness of white walls and neutral furniture. In the main living areas, artificial lighting is minimal and relies on the abundance of natural light seeping through a nearly 20-foot-wide folding glass wall system instead. This minimalistic Jet Black aluminum framed system perfectly blends in with the rest of the unit’s fenestration and complements the overall industrial design of the building. The city’s skyline becomes part of the art, framed by the large glass panels and thin profiles of the seven-panel accordion glass walls.

Lively Interior Design Elements Seamlessly Spill into the Terrace

The spacious terrace is a destination on its own and a rare convenience in most suburban dwellings. When open, the accordion glass walls create an unobstructed opening to an array of outdoors amenities customized to the needs and lifestyle of the homeowners. A rectangular firepit surrounded by a large outdoor sofa offers a lounge spot for sunbathing or hosting friends for a bonfire night. On the other side, an outdoor kitchen with an outdoor grill, sink, and bar seating area is the perfect setup for entertaining and dining al fresco right in the comfort of home. The carefully selected greenery enhances the connection to the outdoors alongside colorful pottery that matches overall aesthetics.

Adding Dynamic Openings for Seamless Indoor/Outdoor Living

An amenity on its own, the nearly 10 feet tall accordion glass walls that connect the main living areas to the terrace offered the ideal solution for a dynamic folding glass wall system on the eighth floor. A low-profile saddle sill creates a barefoot-friendly transition while protecting from the elements, almost as if there was no threshold at all. The available square footage is immediately extended to the outdoor living areas for maximum space optimization, which is a plus in multifamily units. The homeowner’s prioritized outdoor lifestyle is enhanced by these moveable floor-to-ceiling glass walls that flush interiors with abundant daylight and constant fresh air ventilation. When closed, the terrace is easily accessible through a specified swing door customized with a higher kickplate for quick in and out transitions.
