Understated elegance, flawless finishes and high design are the hallmarks of 1243 W. Cornelia Ave., a distinctive single-family greystone located in Chicago's charming Lakeview/Southport Corridor neighborhood. Situated on an extra-large 29' lot, this spectacular 6 bed/5.1 bath boasts all new construction behind its restored vintage facade-and classic curb appeal courtesy of a stately limestone exterior, slate roof with bronze trim, beautiful landscaping/window boxes, and gas lanterns that flank the front door. Once inside, refinished Brazilian walnut floors anchor the home's striking interior design by Wendy Labrum Interiors. The main level begins with a grand foyer and sophisticated living room that finds definition from a French marble fireplace, an antiqued mirror focal wall and custom silk drapery. Beyond lives a lovely formal dining room that flaunts fabulous millwork and a designer chandelier positioned just so. The home's stunning Christopher Peacock-inspired, all-white kitchen wows with Carrara marble counters, a built-in breakfast banquette, a butler's pantry, and a first-class Sub-Zero/Thermador Professional appliances suite, while the adjacent family room welcomes casual entertaining with a generous footprint and a second fireplace. On the second level, 4 of the home's 6 bedrooms unfold, one of which has been converted into a chic media room/library. The third floor is entirely devoted to the primary suite-a spacious retreat with room for a seating area, custom walk-in closets, a massive walkout rooftop terrace with outdoor stone fireplace, and a handsome ensuite with a calacatta marble-topped dual vanity and statement fixtures from Waterworks. This home also features a polished lower level where a rec room, home theater, total gym, temperature-controlled wine cellar and guest bedroom reside. Out back, a private back bluestone patio with grill and a huge, newly designed ipe deck above the garage lay the groundwork for open-air get-togethers. Additional upgrades and amenities include a proper mudroom with built-in storage cubbies, two laundry rooms, a three-car garage, a professionally landscaped parkway, custom downlighting throughout, movie theater, and a whole house HVAC air purification and UV abatement system. A stroll from Southport Corridor for topflight shopping and dining, and five minutes from Wrigley Field for Cubs games and concerts, 1243 W. Cornelia Ave is a refined, design-forward dwelling in a prime location for all-access Chicago living.
