Architect: Ferdinand HompusFootprint: 2,992 square feet (2 bedrooms, 2 baths)From the Agent: "In 1890, Jeanne Cop, superior of the Maricolen Sisters, commissioned Antwerp architect Ferdinand Hompus. However, you no longer need to join the sisterhood to enjoy this imposing, historic building, because today it houses a small residential community with only four units. At the rear, in a very peaceful setting, is the single-nave, neo-Gothic chapel, which dates back to 1879. The contemporary sanctuary is accessed through the entrance hall and a centuries-old staircase. Coffee shops, restaurants, art galleries, and boutiques are popping up here at a rapid pace."
