About This Home

480 N Walnut Ave

This incredible gated downtown estate is like no other. Completely rebuilt in 2013 by Architect Nick Latham and Ziegler Construction, the iconic lodge-style home was originally built by Winston Lauder. Designed around a stunning interior courtyard with water features and expansive outdoor patios, the interior offers four bedroom suites, a glass-walled executive office, and a gracious great room. Perfect for entertaining, the great room and dining area open to exterior patios with incredible landscaping, ponds and streams. The upstairs primary suite features a spa-like bathroom, an enormous dressing room, and its own sitting room. The lower level has enough space for two more bedroom suites -- however the current owners have it laid out as an enormous entertainment/game room. Lots of possibilities here. Additionally there is guest suite (with its own entrance) over the garage -- perfect for a caretaker, nanny or visiting friends. Built from hand 8" x 10" white pine timbers from Wyoming and Idaho and Oakley stack stone, the interiors were hand adzed flat to create interior log walls suitable for displaying artwork. The roof is solid vertical seam copper, and the entire home includes both radiant heat and air conditioning. Estimated replacement value for is between $24 - $25 million. Leave your car in the garage, as downtown shopping and restaurants are just steps away. This is a rare and special property.
