Mediterranean architecture, National Historic Register distinction, over $2.25 million in recent renovations, private resort-style amenities, and a premier Historic Oaks location all come together at the remarkable residence at 312 6th Avenue! Originally constructed circa 1926 for the Faulkner family of Faulkner Concrete, this historic Hattiesburg property was built with extraordinary craftsmanship and lasting strength, including reinforced concrete exterior walls and structural details far beyond what was typical for the era. The home has since undergone two extensive renovations in 2016 and again in 2022-2023, preserving its architectural integrity while introducing world-class finishes and modern luxury throughout. A grand foyer creates an unforgettable first impression and sets the stage for the scale and detail found throughout the home. Formal living and dining spaces flank the entry, including a fireplace-centered living room with adjoining office and a formal dining room finished with striking Canadian Fine & Dandy wallpaper. The kitchen was thoughtfully redesigned with Calcutta Extra Prima Quartz covering both countertops and walls for dramatic waterfall edges and a seamless finish. Features include a Thermador dual fuel gas range, farmhouse sink, pellet ice maker, custom mahogany cabinetry with Restoration Hardware hardware, stained tongue and groove wood ceilings with coffered beams, a large breakfast nook, and generous bar seating. Just off the kitchen, the mahogany-lined den offers rich character with gel-coated wood walls, herringbone solid oak flooring, another fireplace, and access to the enclosed sunroom overlooking the private backyard retreat. Outside, the grounds feel more like a boutique hotel with multiple sitting areas, a saltwater swimmer's pool with upgraded systems, an outdoor kitchen, and a dedicated pool bath conveniently positioned near the entertaining space. Additional main level spaces include a home gym, powder room, spacious laundry room, abundant basement storage, and elevator access to the second floor. The wine cellar is finished with Calcutta Extra Prima Quartz and dramatic lighting, while the connected theater and game room features white epoxy flooring, a full wet bar, garage access for entertaining convenience, and a two-story ceiling with spiral staircase leading to additional storage above. The second level can be reached by either the grand staircase or elevator and is anchored by an expansive primary suite featuring a fireplace with Calcutta Extra Prima Quartz surround, private balcony access, and an oversized custom closet complete with its own washer, dryer, and filtered water source. The completely renovated primary bath continues the elevated design with additional Calcutta Extra Prima Quartz, a large dark stone tiled shower with multiple railheads and body jets, and a freestanding soaking tub designed for relaxation. This is a truly rare opportunity to own one of Hattiesburg's most architecturally significant and extensively renovated historic residences.
