About this home

Prepare to be amazed when you see this 1964 Mid-Century Modern Atomic Ranch rambler situated on a private 1/3 acre in the bucolic neighborhood of North Hill. Designed as a prestigious all-electric Puget Power Gold Medallion home ("Live Better Electrically!"), this classic Eichler-style atrium home showcases a connection to Century 21 and the birth of the Space Needle, incorporating double entry doorknob escutcheons made from Century 21 ashtrays and period-authentic details from the original bullet lights and dazzling Sputnik chandeliers in the dining room and entry to the nostalgic green and yellow tiled bathrooms complete with their original fixtures, as well as a charming vintage built-in radio system. This atomic era gem is crafted with enduring concrete block construction and centers around a dramatic core family room w/original concrete aggregate flooring & high-quality wood paneling. The striking, theatrical entry is flooded w/ natural light from overhead skylights illuminating built-in planters below, separated from the main living space by monumental 18 foot sliding Shoji screens. Updated kitchen w/original charm and new fridge & stove, plus original double ovens. Automotive and hobby enthusiasts will be captivated by the massive attached 20 by 40 foot four-car garage, pre-wired with a 50-amp 240-volt circuit ideal for electric vehicle charging, complemented by ample exterior room for dedicated RV parking. A Rat Pack/Mad Men/Palm Springs vibe in Seattle!
