This remarkable, interior designer owned, Old Town penthouse duplex, and a rare opportunity to own a home that represents their design philosophy at its most personal. Every material is intentional and every inch is designed to be as functional as it is beautiful. Completely reimagined in 2021, the 2,223-square-foot residence blends dramatic architectural scale with warmth, texture, and thoughtful functionality, creating a home that feels elevated yet entirely livable. The heart of the home is the extraordinary double-height living space, where 16-foot ceilings and western light create an immediate sense of volume and drama. At its center, a custom-designed fireplace wall becomes a sculptural architectural element, conceived by the sellers specifically for the space. Beautiful in its simplicity, the design incorporates concealed storage that disappears seamlessly into the architecture, a signature example of the designer's ability to make function feel effortless. White oak hardwood floors bring warmth and continuity throughout the home, while a fully integrated Lutron smart-lighting and motorized-shade system allows the mood of every room to shift throughout the day. The result is a home that feels calm, cohesive, and deeply considered, with every cabinet, fixture, tile, window, and surface selected as part of the complete 2021 renovation. The kitchen is refined, highly functional, and designed for real life. Custom cabinetry gives the space a tailored, furniture-like quality, complemented by durable quartz countertops and a generous peninsula housing dual-dishwashers. A Viking range, Fisher & Paykel refrigerator, Thermador and Beko dishwashers, wine refrigerator, Brizo touch faucet, and dedicated instant-hot and filtered-cold drinking water system were thoughtfully integrated into the design. Nothing feels added on. Everything has its place. The main-level primary suite offers the ease of single-level living and a private retreat from the more social spaces of the home. The bath pairs heated porcelain floors with a soaking tub, separate double shower, double vanity, and walk-in closet, creating a space that feels serene, warm, and quietly luxurious. Upstairs, two additional bedrooms and two full baths are joined by a skylit den that brings flexibility to the floor plan. Use it as a home office, media room, reading lounge, or creative space. Skylights and motorized window treatments draw in beautiful western light, while the separation between levels gives the home the privacy and function of a single-family residence. Set within one of Old Town's most coveted vintage buildings, the home pairs contemporary design with the architectural character of its surroundings. From the windows, enjoy a distinctly Old Town backdrop and a sense of place that could never be replicated in new construction. Residents also enjoy a common roof deck with built-in grills and a pergola, elevator access, a bike room, and a secure package room. One deeded heated garage space and a private storage cage are included. All of this is just steps from Wells Street, Armitage Avenue, the lakefront, and the best of Old Town and Lincoln Park. This is more than a beautifully renovated penthouse. It is a designer's own home, created without compromise and shaped by the people who know better than most how a home should look, feel, and live.
