Brooklyn's clapboard houses are becoming less and less common, but this stunner at 106 Cambridge Place in Clinton Hill isn't going anywhere. The 1880 neo-Grec townhouse falls within the Clinton Hill Historic District, which protects some of the neighborhood's other gems like the impressive 31-room mansion at 278 Clinton Avenue. The townhouse on Cambridge Place is currently configured as a two-family building with a ground-floor apartment. The house has been renovated in its 135 years but it still posses charming pre- pre-war embellishments like three wood-burning fireplaces and eight mantles. Its ask? $2.89 million.
