Description

Introducing 427A 8th Street, a stately Neo-Grec brownstone with gorgeous curb appeal that flawlessly pairs a modern renovation with a rich collection of intact original details. Perfectly situated off bustling 7th Ave and just a stone throw away from Prospect Park, this stunning home offers four bedrooms, three and a half bathrooms, and over 3,000 square feet of refined living spanning across four floors. Exceptionally rich in original details, the house retains five original mantels, pumpkin pine floors, plaster crown moldings and ceiling medallions, pocket doors, the original window shutters, and a stained-glass skylight. The home's remarkable original details are thoughtfully complemented by all the modern comforts one would expect, including the unexpected luxury of a newly restored plunge pool and hot tub. At the center of the home is a renovated kitchen finished with rift white oak cabinetry, marble and soapstone countertops. The comprehensive suite of appliances includes a Viking range, Fisher & Paykel refrigerator, Miele dishwasher, Bosch speed oven and microwave, a built-in Bosch coffee machine, and a Liebherr dual-zone wine refrigerator. Recent improvements extend throughout the interiors, with Herman Miller and Schoolhouse lighting complemented by Buster + Punch switches. Recently installed split-system HVAC throughout ensures comfortable living in any season. Three newly renovated full bathrooms incorporate Calacatta and Blue de Savoie marble, while custom millwork adds another layer of detail throughout the home. The exterior has been extensively upgraded with new bluestone pavers in the front and rear gardens, a new outdoor kitchen and pergola, integrated lighting, and of course, the plunge pool with custom cover. Not leaving anything overlooked, the lower level has been fully updated with new floors, lighting, and custom storage. This floor currently serves as a dedicated office, a home gym, and additional storage. Superbly located just a block from the F/G at 9th st and around the corner from all of the shops, restaurants, cafes, and amenities that have made Park Slope a worldwide destination, 427A 8th Street combines the scale and original character of Brownstone Brookly with a stylish and intentional collection of modern upgrades not commonly found in homes at this price point. Currently zoned for PS 39. Schedule your private appointment today!
