This 4-story single family limestone is an architectural standout situated along the gold coast of historic Park Slope. Built in 1899 by noted Brooklyn architect-builder Peter J. Collins, it stands on one of the most coveted, Landmarked, tree-lined blocks in Park Slope. It's situated a half block from the famous bronze Panther monuments at the Third Street entrance to Prospect Park. The 20' wide townhouse underwent a meticulous multi-year renovation, restoring all the original detail, including magnificent parlor columns, level-5 finishes, and stained glass skylight. Woodworking throughout is pristine and includes mahogany, Birdseye maple, and cherry. The facade and interiors are impeccably maintained with a refined, yet traditional sensibility. Its living space currently boasts a square footage of 4500, configured as an upper triplex and a garden level apartment with a separate, private entrance. There are 5 bedrooms with 4 ensuite bathrooms, and a powder room discreetly and conveniently located on the parlor level. The bedrooms are beautifully scaled to enjoy the full width of the house. Windows have impressive proportions, particularly in the primary suite, framing a delightful south-facing Juliet balcony. Natural light fills the house. There are 3 intact wood burning fireplaces, two of which have an added gas component. There are 2 private outdoor spaces to enjoy, including the rooftop, which is easily accessible through a bulkhead. This roof has been rebuilt with steel reinforcement and is equipped with water, electricity and gas. A rear bedroom in the garden unit provides access to a bluestone patio garden. The home's depth was extended to include a stunning back parlor den with graceful east-facing stained glass windows. Security cameras, Sonos audio, and multi-zoned temperature control throughout. A clean, brightly lit cellar measures the full footprint of the house providing abundant storage.
