One Team. Every Detail. One Extraordinary Experience.
Imperia Lake Union brings together a historic Seattle event venue, full-service catering, an atelier florist, and comprehensive event planning under one roof. From weddings and nonprofit galas to corporate events, milestone celebrations, and celebrations of life, our experienced team delivers exceptional hospitality, inspired cuisine, floral artistry, and seamless coordination—whether your event takes place at our venue or yours.
Originally built in 1927, our historic venue overlooks Lake Union from Seattle's Eastlake neighborhood. This 6,000-square-foot event space combines timeless architecture with modern amenities, featuring soaring chandeliers, hand-crafted copper ceilings, a built-in stage and dance floor, hidden rooms, and sweeping waterfront views. Inspired by Old Hollywood glamour and rumored to have once been a Prohibition-era speakeasy, it's a venue unlike any other in Seattle.
Beyond our venue, Imperia provides off-site catering and event services throughout the greater Seattle area. Whether we're welcoming guests into our historic home or transforming another venue, our mission is simple: create beautifully designed, flawlessly executed events that are effortless for every host and unforgettable for every guest.
