This unassuming little cabin has a secret. Built by Olson Kundig Architects for a couple who visits the Olympic Peninsula for the fishing, the cabin is made of mostly of steel and supported by 4 steel columns. The interior has the living level on the main floor while a sleeping loft above was constructed out of lumber and materials the owner happened to have on hand. The taller columns serve to keep the cabin out of the flooding the nearby river provides from time to time. So what is Sol Duc Cabin’s secret? When the couple leaves the property they can completely close it up with the cantilevered shutters leaving it completely impervious to intruders of any kind. Pretty cool.
