Park Slope seems to have an endless supply of perfect Victorians for sale. This one at 505 1st Street has African mahogany built-ins and mantels in the formal rooms that look like they’ve never seen a paintbrush. There are also inlaid parquet floors, pocket doors, molding and plasterwork, an elaborate staircase, an entry seat, two wood burning fireplaces, original shutters and just about every other original detail you could wish for, although it looks like the original passthrough sinks may be gone. It’s currently configured as an owner’s triplex over a garden rental, with a kitchen in the third parlor in the extension. The bathrooms are updated, and other modern improvements include a deck off the parlor kitchen and a powder room tucked under the stairs on the parlor floor. Perhaps most crucially, especially for this neighborhood, it comes with a deeded parking space across the street. Do you think the $3,950,000 ask sounds about right?
