Description
405 Union Street, Carroll Gardens
THIS is everything. Location and Style that packs a punch. Sitting pretty at nearly 20 feet wide on a 90 foot lot, this legal 3 family brownstone (currently used as a 1 family) has been lovingly restored and updated and will delight you at every turn.
Up the stoop, through the magnificent and massive original double doors find impressive parlor floor which is the heart of the home. With its soaring 15 foot ceilings, original gilded pier mirror, floor to ceiling windows, custom millwork, and 2 original marble mantels.
This level is home to both living and dining and an efficient sweet kitchen with all the creature comforts including its unique enamel oven and pink millwork. Every floor of the home has a bathroom and the parlor is no exception with its tidy water closet for guests. Off the kitchen find steps down to the garden with new hardscaping and lush plantings and wisteria covered pergola. The garden is both a dramatic oasis and makes for a lovely vista from all the back windows of the home. The garden level can easily be converted to an income producing apartment, currently there is a snack station which could convert to a full kitchen effortlessly. This floor is home to a guest suite with full windowed bathroom and an oversized family room/den.
The 3rd story is the primary suite with its sunny updated ensuite bath. The top floor is currently kids quarters with 3 full bedrooms and a full windowed bathroom.
A classic brick archway spanning the length of the full basement and building provides added support and is surrounded by the original stone foundation. The rear basement hatch has a light-well, which can be added in front as well. An easy transition to becoming a finished basement, media/work or home gym. This level is full ceiling height and home to the washer/dryer as well as ample storage.
Located just one block to Smith Street, a short distance from trendy Gowanus or just walk east on Union Street to Prospect Park, the Botanic Gardens and enjoy the Saturday farmer's market in Park Slope. Close to amazing dining, provisions, and small local boutiques on Court Street, you may never need to leave Carroll Gardens!
