No detail was overlooked in the complete gut renovation of this sun-filled, five-story Italianate townhouse on a quiet, tree-lined landmarked block in prime Chelsea. Originally built in 1859 on a 21-foot-wide lot, the home features a deep garden with a unique through-block exposure to the north and strong light from the south and west. With seven bedrooms in the main house, this home also includes a semi-attached guest apartment with two additional bedrooms and a media room. The floor plan was reimagined for a modern lifestyle by leading architecture firm Moulin & Associates to create expansive entertaining spaces, two kitchens to provide separation for catered events, privacy for the bright bedrooms and ample additional room to play. Upon arrival at the handsome structure one is greeted by the original 19th century brick facade that has been cleaned and repointed, rebuilt front roof dormers of Vermont slate that were angled toward vertical to create a feeling of additional airiness, a restored roof cornice, and new brownstone resurfacing of the lower level, stoop and arched entry entablature. Interior finishes were carefully curated to preserve original details and framed with modern counterparts. Custom fabricated mahogany windows and rear facade doors are paired with custom-stained oak flooring throughout that seamlessly meets the restored original staircase and balustrades. The home also features four custom-built and restored fireplaces and corresponding mantles, three of them gas and one woodburning. Designed to accommodate the highest standard in living, the dual state-of-the-art kitchens feature expansive alder wood kitchen cabinetry and tasteful Blue de Savoie marble countertops, Subzero refrigerators, 48 Viking vented gas range in the master kitchen, and a total of three Bosch dishwashers. The seven full baths and two powder rooms are also fitted with high-end fixtures including Zebra Gray and Pietra Bedonia natural stone by Stone Source and triple Robern medicine cabinets in the master bath. Laundry is easily accessible with two large capacity washer/dryers on the first level of the guest apartment and an additional stackable unit on the second floor. The 1600SF+ outdoor living areas were as thoughtfully crafted as the interior of the home. Enclosed by custom wood fencing, a walkway spans from the rear of the garden level to the lower garden, and the lower garden is linked to the upper garden via bluestone steps. The sunken garden is clad in Pennsylvania bluestone and the larger elevated garden incorporates bluestone slabs with grass framing accented by planting beds on the outer edges. In addition to the terraces on the parlor and fourth floor, the home is crowned by a landscaped roof deck with picture-perfect views of the landmarked block. The entire house is supported by new wiring and mechanicals including central air conditioning and supplementary hot air heating throughout, perimeter hydraulic heating generated by a gas boiler via radiators and floor recessed convectors found throughout four independently controlled zones. The house is currently undergoing renovation, slated for completion this spring.
