A 37-acre private estate that is entirely yours for your event. Manicured gardens, a private ponds with English swans, fountains, and two prestigious event tents. Accommodates up to 400 guests. Swedish immigrant Erick Sanders, a successful business and lumberman in Seattle and Bainbridge Island, built this elaborate craftsman house for himself and his wife Sara. The Sanders and several partners purchased 1,100 acres of land in the Green River Valley west of Kent as an investment. After constructing the Mill Pond and sawmill they began to harvest the timber. As a result, the open fertile farmland allowed for the start of what is now known as the Smith Brothers Dairy Farm. On this land, they founded the standard dairy and mill operations. Between 1908-1910 the Sanders’ mansion was constructed with lumber from the recently invested mill, salvaged glass from the Alaska-Yukon-Pacific Exposition, and excess bricks from the West Valley Highway construction. Most of these original features that have made the Sanders Mansion a unique and modern home of the early 1900’s and been maintained and restored to keep up our Estate as a historical landmark. You can still expect to see original light fixtures in the home and enjoy a warm shower in very rare and original “cage shower” in the upstairs restroom. The mansion was to be the Sanders’ retirement home, equipped with every modern experience and decked out in plants and trees galore. As the years went by the unobstructed view of the valley farmlands and Mt. Rainier were just a few benefits that the Sanders’ got to enjoy within their property. As for the 21st century, the Sanders Estate is our lush home away from home tucked in the corner of Kent.

Warm Springs Inn & Winery traces its roots to 2006, when the Szmania family purchased a 20-acre farm and pear orchard along the Wenatchee River. Two years later they planted rows of Sangiovese, Syrah, and Merlot, and by 2012 had brought in their first harvest, with early vintages made under the guidance of winemaker John Patterson at Patterson Cellars in Woodinville. In 2013, the family expanded into hospitality, purchasing the historic 9,000-square-foot mansion on the property's 10 riverfront acres and reopening it as an inn in April 2014. Today, BCV wines are produced in small batches on-site in Wenatchee, from harvest through crush, fermentation, and bottling — eight wines in all, including Merlot, Syrah, Sangiovese, Cabernet Franc blends, and a Rubi Reserve Port, several of which have won medals at the North Central Washington Wine Awards. Set between Wenatchee and Leavenworth and surrounded by cherry orchards and old-growth trees, the inn offers six guest suites, a wine bar and tasting room overlooking the river, and grounds that host both intimate indoor weddings and riverfront outdoor celebrations for up to 250 guests. Chef and owner Ludger Szmania prepares breakfast for guests each morning.
