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.

As a licensed real estate brokerage, Estately has access to the same database professional Realtors use: the Multiple Listing Service (or MLS). That means we can display all the properties listed by other member brokerages of the local Association of Realtors—unless the seller has requested that the listing not be published or marketed online.
The MLS is widely considered to be the most authoritative, up-to-date, accurate, and complete source of real estate for-sale in the USA.
Estately updates this data as quickly as possible and shares as much information with our users as allowed by local rules. Estately can also email you updates when new homes come on the market that match your search, change price, or go under contract.
