“Instead of confining the house’s different uses into separated rooms, they have been connected with each other, aiming at producing the general feeling of spatial expansion,” said the firm.

The 510 Cabin is one of Leggitt's designs, executed with the help of student apprentices.

Working with the original Mario Botta-designed building, the 10-story expansion includes a new dedication to providing communal outdoor spaces. This includes 170,000 square feet of new and renovated indoor and outdoor galleries dedicated to the museum's cherished collections. Photo courtesy of SFMOMA.

The architects designed the home’s expansion with the knowledge that the owners plan to continue the renovation when their budget allows it. "We wanted to put everything in the right place so it doesn’t have to be undone later," says Corti.

"The border between inside and outside fades because of the perpetuation of the washed concrete flooring, reminiscent of cannon bases. Just like the shutters of the old barn, the sliding facades of the expansion offer the opportunity to seal off the guest complex entirely," explains Vanhoutte.

Olson Kundig refurbished this 1950s building as a flexible off-site exhibition space for SFMOMA's Project Los Altos in downtown Los Altos, California. The firm replaced the front facade with a double-height, floor-to-ceiling window wall that can be raised or lowered at the whim of the user.

MDF panelling also allowed for contraction and expansion of the moving vessel.

The San Francisco Museum of Modern Art Rooftop Garden in San Francisco, California. Designed by Jensen Architects/Jensen & Macy Architects. Winner of the 2011 Institute Honor Award for Architecture. Project description: "The SFMOMA’s rooftop garden is an open-air gallery defined by the intersection of sculpture, space and light. The entire back wall of the museum’s top floor is removed, allowing a seamless connection from gallery to garden. A large panoramic window at this new opening offers an elevated view to the garden, presenting it like a landscape painting inside the gallery. A glazed long-span bridge links the museum to a garden pavilion that in turn opens out to the garden through large sliding glass panels."

The structure of the coop was inspired by the new bus shelters and newsstands in New York City.

Sited on a flat lot, the property includes two generous, enclosed yards that can accommodate expansions or the addition of a pool.

The expansion includes a larger kitchen, a new master bedroom and family room, and two new decks. The cedar shingles on the exterior nod to the original structure.

Melbourne firm Splinter Society’s main goal for the Bungalow 8 renovation and expansion was to create "a more modern, free-flowing series of connected living spaces,

"The geometry creates varied spatial experiences—expansion and contraction horizontally and vertically—reinforcing the series of stepped courtyards," says architect Andrew Simpson.

With 25% more working space than the previous kitchen, the expansion is meticulously organized and allows direct visual connections between all stations.
