This $4M Carroll Gardens townhouse has been elaborately redone with concrete, metal, and rough-hewn wood

Tucked behind an unassuming brick facade at 141 1/2 Nelson St. in Carroll Gardens is a slick one-family townhouse with a distinctive modern style. Gut renovated in 2013 and listed for $3,950,000, the four-bedroom, four-and-a-half bath mixes warm materials like wood and brick with sleek elements of polished concrete, steel, and glass. 

The asking price is significantly higher than the median sales price for a townhouse in Carroll Gardens, $2,527,500. This is arguably a reflection of all the work that has gone into it.

The parlor floor features a wood-burning fireplace, a partial wood floor with herringbone design, built-in shelving, and a Workstead light fixture. 

Another wood-burning fireplace can be found in the kitchen, which has a concrete island, a farmhouse sink, Wolf and Sub-Zero appliances, custom cabinets, and a brick backsplash. There's a powder room on this level as well. 

The rear of the house has a double-height glass and steel wall measuring 20 feet high, and double French doors that lead out to a terrace. 

Stairs lead down to the sunken backyard where there's a gas grill, a prep area, and sink.

The second floor has a family room with a gas fireplace, wide-plank pine floors, and an exposed brick wall and ceiling beams. Two bedrooms and two bathrooms can be found on this floor also. 

The third-floor master bedroom has a skylight. There's a master bathroom with a soaking tub and a steam shower, and the master suite also features a large walk-in closet and a balcony with an outdoor shower.

Below all that on the garden level is a one-bedroom rental unit with an office space and garden access. 

The townhouse is in prime Carroll Gardens, near popular eateries like Frankies 457 and Buttermilk Channel. The nearest trains are the F and G at Carroll Street, four blocks away. Taxes are $334 a month.
