Functioning as one of the Eastside's only true live-and-work buildings, this Market Street address is purpose-built in Downtown Kirkland. Designed for an owner seeking both residential luxury and professional functionality, the property offers rare flexibility without compromise. The top-floor penthouse residence makes a lasting first impression. A sculptural entry unfolds beneath a soaring curved ceiling, illuminated by natural light. A sweeping staircase traces the wall above layered stone flooring, setting the tone for what follows. Spanning three versatile levels to suit a dual purpose owner, the home is finished in hardwood and surrounded by expansive windows capturing Market Street outlooks. The living room is set by architectural pillars and a statement fireplace, while the sky deck opens to panoramic views of Lake Washington. The primary suite features a sitting area, fireplace, and refined five-piece spa bath. A private office completes the penthouse level. Each floor has a secure entrance, allowing separation of residential and professional use. The professional space begins with a formal hallway for private clients from the parking area into a reception area, 4 private offices & a boardroom. The ground level has four ensuite bedrooms and plumbing in place for a second full kitchen. Offering over 7,000 square feet of scale, this is an offering rarely seen in Kirkland.
