Overview

Perched high above the sparkling waters of Casco Bay, 17 Harmony Hill is a place where every day begins with beauty and ends in serenity. Wake each morning to sunrises spilling shades of gold, pink, and blue across the ocean horizon, visible from every bedroom. Thoughtfully designed with ensuite bedrooms for comfort and privacy, this coastal retreat blends timeless elegance with effortless living. The newly opened front porch invites you to slow down and savor the view--whether enjoying a quiet morning coffee, watching the iconic Chebeague Island Ferry come and go, or taking in the rhythm of boats gliding across the bay. Inside, sun-filled living spaces are welcoming, enhanced by newly added gas fireplaces in the living room and primary suite. Designed for relaxation and entertaining, the home features an open dining area flowing seamlessly into the inviting living room, where ocean views create a backdrop for everyday living. The kitchen is outfitted with Thermador appliances and opens gracefully to the heart of the home. Additional first-floor rooms allows flexibility for a home office, den, library, or fitness space. Life on Cousins Island offers endless opportunities for adventure and tranquility. Spend summer days paddleboarding along the shoreline, secure a mooring for boating excursions, or simply enjoy the beauty surrounding you. Recent improvements, including a newly paved driveway, freshly paved neighborhood road, and newly painted cedar fence, further elevate the appeal of this extraordinary property. Hop the ferry over to the Chebeague Island Inn for a fabulous dinner in an 1800s inn. The restaurant is run by the owners of the famous 12 Restaurant in Portland. Crafted by renowned builder Dale Bragg, this remarkable home also features a whole-house generator, high-end heating and cooling systems, energy efficient insulation upgrades, an extra-deep garage with ample room for storage or hobbies, and a short drive to Portland and the Jetport.
