About this home
Welcome to the destination community of Alterra. You'll find 62 new construction homes connected to two trail systems. Community also has sidewalks on both sides of the street, stunning trees and peak-a-boos of mountain ranges all around. We present the Plan 5. This home will greet you at the front door with a 3 story open entry. The garage is so large, you could park 2 cars and still have room for a large gym, hobby area, or more storage than you could dream of in a new construction home! It includes a private lower-level retreat as well as a main-floor guest suite ideal for visitors or multi-generational living. At the heart of the home, the gourmet chef’s kitchen impresses with a sub-zero refrigerator and JennAir appliances. In addition, you have a walk-in pantry attached to a butler's pantry. Alongside the enormous covered deck and covered back patio with fireplace, it's perfect for entertaining. Don't miss the main-floor office providing a quiet workspace and the expansive loft offering an additional lounge or media retreat. Last but not least, the huge primary suite features separated vanities, a soaking tub, glass enclosed shower w/rain shower head and an oversized walk-in closet w/built-in closet organizers. Scheduled for completion in 2026. Broker must accompany and personally register buyer at first visit. Located within the highly acclaimed Issaquah School District.
