3346 W Cullom Avenue Behind the classic Chicago brick of 3346 West Cullom lies a masterclass in modern living. This architect-owned residence transcends traditional renovation, blending luxury with the quiet precision of building science to create a home that truly looks after its inhabitants. Refine your daily flow. Your days begin in the expansive modern kitchen, anchored by professional-grade Bosch appliances, an expansive quartz island, and a coveted pantry designed to keep the workspace clutter-free. The kitchen is the social heart of this home and it flows effortlessly into the family room and outdoors onto a covered deck -the perfect setting for morning coffee overlooking your private, native-landscaped oasis. Formal living and dining spaces, paired with a bright sunroom and a perfectly placed powder room, provide versatile environments for both work and relaxation. Upstairs, the sanctuary deepens. Three bedrooms are wrapped in sound absorbing insulation, ensuring a rare, "library-quiet" atmosphere. The primary suite serves as a true escape, featuring a spa-like bath and a private balcony with peaceful views of the tree-lined bikeway. A custom walk-in closet makes getting ready for the day a joy. A second floor laundry room and generous closets throughout add function to your uncluttered style. The lower level adapts to your needs, offering a spacious family room, a full bath, an executive-style home office (or fourth bedroom), and a gracious fifth bedroom that serves as an ideal guest suite. The home's most significant benefit is felt rather than seen. A constant stream of fresh, filtered air is managed by dual ERVs and centralized dehumidification, mitigating allergens and urban dust. This airtight, ultra-insulated envelope makes the home remarkably silent and energy-efficient. Sustainability is integrated throughout, from the rooftop solar PV system that provides clean and free electricity to the high efficiency mechanical systems. Outside is an urban retreat. Meandering paths lead through a professionally designed native garden and a Maine Cedar hot tub, designed for low maintenance, energy efficiency, and year-round outdoor relaxation. The two car garage has its own electric service which makes adding Level 2 EV charging easy. Excellent walkable location with bodegas, groceries and restaurants nearby and the Brown Line is just a 15 minute walk away. Cyclist enjoy the greenway location, leading to Horner Park and the Chicago River. From the wildflower garden at the curb to the high-performance lifestyle focused design within, this is a rare opportunity to own a home that works harder for your wellness.
