Description

Sitting atop the highest point in Lake Oswego lies “Summit 18,” a signature home in the 2025 Street of Dreams. Built by award-winning Elite Development PNW, this 5,640-square-foot residence captures commanding views from the top of Mount Sylvania—offering a rare blend of elevation, elegance, and design excellence. From the moment you arrive, it’s clear no detail was spared. Thoughtfully designed across three levels and connected by a custom elevator, Summit 18 features five bedrooms and four and a half baths, with a layout that balances grand scale with comfortable livability. The main level hosts a gourmet kitchen equipped with a built-in refrigerator, double ovens, gas range, and a statement island—all open to light-filled living spaces with high ceilings, wide-plank hardwood floors, and a sleek gas fireplace. Every surface and finish was chosen with intention. Upstairs, the primary suite provides a retreat-like experience with large picture windows, a spa-inspired bathroom with a soaking tub, heated tile floors, and a generous walk-in closet. Additional bedrooms offer flexibility for guests, home office, or multi-generational living. The lower level adds more room to entertain or unwind—ideal for a home theater, gym, or bonus space—with full bath access and seamless flow to the outdoors. Located in the desirable Mountain Park community, residents enjoy access to a private gym, lap pool, sport courts, and scenic trails. With a gently sloping lot, three-car garage, and panoramic views stretching over the city and surrounding hills, Summit 18 is more than just a home—it’s a statement of modern luxury at elevation.
