Tasked with creating a multi-use guest pavilion on a relatively small Northern California vineyard lot that could also host sit down dinners for up to 60 people, designers at Anderson Architects started by asking the key questions: “Where should it be within the property?” “How much floor area do we need for a 60 person dinner?” “How much volume do we need for a basketball court?” “We also always tell ourselves to look at the landscape first, let it dominate and lead it through. The building took the form of a large Napa Valley barn.

Noise-canceling headphones work by producing sound waves that are 180 degrees out of phase with ambient sound waves, like those coming from airplane engines or air conditioners. Basically, the sounds meet and cancel each other out to produce silence, so only the music can be heard.

The newest version is the QuietComfort 25. They’re a mix of the brand's classic aesthetic and new technology. Hardware updates to the preceding QC 15 including noise regulation that Bose says reduces the “hiss” sometimes associated with noise-canceling headphones.

With a minimal and understated look, this floating staircase and landing design evokes a less-is-more philosophy and architectural style. Architect Carlo Gaspari converted a former knife-making workshop in Abruzzo, Italy, into a sophisticated residential property. The design pays homage to the home’s name—Casa del Ferro (the Iron House)—by using iron within the interior design, such as the staircase.

The legend behind the headphones' creation is that founder Amar Bose was dissatisfied with the airline-issue headphones provided on a flight he took in 1978. However apocryphal, he is said to have written down calculations before landing, and those plans led to the first noise-canceling headphones that came out years later.

The addition’s two stories of cedar-framed sliding doors and window provide generous views of the house’s prized jacaranda tree. The addition’s polished concrete floor and white cladding extend into the garden, drawing occupants to the serene rear porch. There, they can relax on stools designed by Alvar Aalto and Charles Wilson while admiring the luscious greenery.

The Bose QC 25s are “over-ear” headphones, which mean they entirely surround the ear with padding to block out as much noise as possible. Some people find them cumbersome when worn for extended periods, but the padding on the top band keeps them from feeling heavy.
