This enormous Federalist Society Hill townhome was built c.1810 and renovated, in 1972 with a distinctly mid-century Modern approach, by renowned Philadelphia artist Sam Maitin with the help of his brother Irving (AIA), an award-winning, Harvard- and Penn-educated architect. The Artist’s studio still occupies the first floor and features a massive open space with 10-foot-high ceilings; the three floors above were the family residence. A spacious eat-in kitchen at the rear of the second floor opens onto a large living area with fireplace and the front room which has a full en-suite bath and can serve as both family room and guest bed. The third floor has two well-proportioned bedrooms and shared bath, and the top floor has a primary bedroom suite with an anti-chamber/library/sitting room separated from the sleeping area by a 12-foot x 8-foot barn door. The house is looking for its next iteration from a buyer who wants to put their own imprimatur on this a distinctive and stately home on one of Society Hill’s finest blocks. The first floor can remain a professional space or be transformed into the family living area, making room for more beds on the upper floors. With the included additional lot (703 Addison) that extends all the way back to Addison Street in the rear, there is ample room for 2-car parking along with a very generous garden area. Please note the RM1 zoning which can allow for an owner's unit on the upper floors and an income unit to be built on the lower level.
