Case Study: Marina Penthouse

In the Marina District of San Francisco, expanding an existing condominium is a challenge. But rather than leave such a desirable location, many people would rather find a way to make do.

The design firm William Duff Architects (WDA) figured out a way for his client to get both a fitting expansion and a way to make do with the condo they loved. This “perfect solution” story involved one big move – adding a master-suite penthouse to the existing third-story condominium – but also smartly integrating the existing roof as additional living area.

As result, WDA created a far more sustainable design. And intrinsic to this green solution was the use of NanaWall.

Design and Finish Options to Match Aesthetic

WDA has used NanaWall products extensively in their high-end projects throughout the Bay Area. Because of NanaWall’s wide selection of styles and finishes, Duff was able to match the trim on the WD66 system to the teak stains found throughout the penthouse. He was also impressed with NanaWall’s professionalism and liked that they are a local company with a global presence. “Their staff is knowledgeable and easy to collaborate with, and a good portion of their products are produced locally,” Duff comments.

“In addition to bringing the outdoors in, NanaWall allows in copious amounts of sunlight, which is an inherent energy-saving factor."

WDA’s marina penthouse utilizes the four WD66 panels, a standard folding or paired-panel, wood-framed system designed to provide an opening up to 39 feet. “NanaWall’s clean lines matched our client’s modern aesthetic,” Duff contends. In addition, the homeowner can open their system to usher in natural ventilation and the sounds of the city.
