A stunning glass penthouse in the heart of Portland, Maine, has set a new benchmark for urban luxury, becoming the city's most expensive condominium with a price tag of $3 million. This architectural standout offers more than just panoramic views of the historic port city; it features a truly unique outdoor oasis high above the streets.

The residence's crowning jewel is its expansive roof terrace, which boasts a lush, irrigated lawn of real grass. This elevated park in the sky requires dedicated maintenance, including a weekly mowing, to preserve its pristine condition. The feature exemplifies the property's seamless blend of sophisticated urban living with a surprising, natural tranquility.

Spanning the entire top floor of its building, the penthouse is defined by walls of glass that flood the open living spaces with light and frame dramatic vistas of the cityscape and waterfront. The design prioritizes a seamless indoor-outdoor connection, making the private terrace a natural extension of the home's luxurious interior. This unprecedented offering reflects Portland's growing appeal as a destination for high-end real estate, combining Maine's coastal charm with cosmopolitan elegance and unparalleled amenities.
