This exceptional custom home is located in the award-winning I'On community overlooking the tidal marsh of Hobcaw Creek. This is a rare find that offers multiple unique spaces including a boathouse, a separate studio apartment, and a sprawling flex space on the ground level! This home has had extensive renovations, including to the full front elevation of the home, main level floorplan improvements that created a new foyer, two offices, and a homework area, as well as the addition of high end light fixtures, and the completion of a previously unfinished lower level. Upon entering the zellige tiled foyer with hidden mudroom cabinetry, the long view through the arched entry frames the lovely green marsh view visible through the many doors to the screened porch that wraps aroundthe main living areas. The living room boasts a soaring cathedral ceiling, that showcases exquisite double chandeliers and a grand stucco fireplace with exposed iron beam detail. The gorgeous white kitchen features a long island with new AGA induction range, new Subzero refrigerator, two pantries, and opens to the lovely light filled dining room. There is a convenient work area designated for children to spread out homework or art projects close by, as well as two new offices outfitted with elegantly designed built-in cabinetry. The primary suite is also located on this main level, and has been freshly wallpapered in Phillip Jeffries grasscloth, and has access to the screened porch and scenic marsh views. The top floor features a fantastic cozy playroom or den with full height bookshelves and storage cabinets and a brick feature wall. Brand new wool carpet extends throughout this floor, including in the three generously sized secondary bedrooms on this level, all with gorgeous decorative wall trim detail and walk-in closets. The lower level of this home is split down the middle with a walkway through to the spacious backyard. The right side of the lower level can be accessed from the house, garage, or outside, and has the perfect guest suite, and additional den/flex space. The left side lower level has a separately accessed full gym or studio space complete with wall to wall mirrors, climbing, and rope wall. A convenient wet bar with fridge/freezer, storage and dishwasher make this the ultimate entertaining space. Throw open the French doors to the back patio and firepit overlooking the beautiful marsh for the easiest party ever! Walk out the back gate directly onto the I'On Marsh trail, a shady walking path that weaves through the waterfront section of the neighborhood to multiple crabbing and viewing docks, and ends at the main I'On dock at the Creek Club. The entire property has been relandscaped with multiple stucco raised flower and vegetable garden beds have been added to the yard, "English garden" pea gravel pathways, and bluestone patio. This is an amazing opportunity to have a large family sized home in I'On, at just under 6,000sqft, on one of the most desirable cul-de-sacs in the neighborhood. Ideally located about ten minutes from both downtown historic Charleston, and the beaches of Sullivans and Isle of Palms.
