The William Deforest House is an exquisitely restored commercial office building in lower East Rock. Located at the edge of Downtown NH & steps from Yale, it offers convenient access to highways 91 & 95. The Italian Villa Style house was built in 1858 for a well known physician as his residence. The stately brick mansion was meticulously restored in the early 2000s by Petra Construction w/ incredible attention to detail & no expense spared. The building boasts a versatile 4,016 SQ FT of office space on 3 levels w/ additional attic space w/ expansion possibilities. Remarkable architectural details throughout include 11 FT ceilings, rare pierced plaster frieze molding, ornate Fireplaces and oversized windows. The 1st floor offers a spacious reception area, a conference room, a kitchen area, 2 spacious offices, 2 1/2 baths & a one-of-kind executive office w/ a striking hand-carved wood archway. The 2nd floor has 3 additional elegant offices with 1.5 baths, and a large conference room w/wood paneling and molding, built-ins, and wiring for high-speed video conferencing. The lower level has a private entrance with an additional 1,087 sq ft of space including 2 offices, 3rd conference room & 1/2 bath. Separate entrance provides flexibility for income or a space for another business. The building has gas heat, CA & updated electrical. The exterior has a gorgeous entryway & parking lot for 12 cars. Truly a rare opportunity to own one of New Haven's most distinguished buildings. The building is currently occupied by owner/user as commercial office space, but the building would be an excellent candidate for conversion back to residential use.
