Seattle studio Wittman Estes has designed two elevated wings to open up and extend a beach house from the 1940s in Hood Canal, Washington.
The extension to Aldo Beach House was created for two grandparents, who owned the original cabin and wanted to turn it into a permanent home with more room for the family.
The new extensions have doubled the living space. Top: the house is located by the Hood Canal
Wittman Estes, which has worked on a number of sites with delicate ecologies  and near the shoreline, was asked to double the square footage of the house without disturbing the ground.
The house is located on the shore of the Hood Canal fjord, one of the main basins of Washington's Puget Sound.
The studio used pin piles and thin steel columns to lift two new extensions aboveground, maximising the footprint of the house while also protecting the fragile shoreline. Pin piles and steel columns were used to raise the extensions
"Pinned by the shoreline on the west, and a steep slope on east, the site only had room for expansion to the north and south," Wittman Estes founding principal Matt Wittman told Dezeen.
"We discovered the original cabin was built rotated from the side property lines," he added. "This gave the north and south projecting wings sculptural triangular shapes, which resulted from expanding the building out to the side setbacks."
