Reintroducing the ultimate Mercer Island lifestyle. A bespoke home on 100' of unparalleled west facing Lake WA frontage is built at the water’s edge. Designed for indoor/outdoor living and entertaining; the one-of-a-kind terrace perched over the water could not be built today. French doors and folding windows link al fresco energy to the warmth inside. Studs up remodel in 2016 spared no expense and added a separate carriage house. Notable details include limestone and sandstone imported from a quarry in France, floors reclaimed from a 16th century Italian monastery, specimen gardens, and a dock w/covered slip. Elan Smart Home System lets you manage your home from your phone. A generator runs the entire home if needed. Front row for Seafair.
