Two adjoining townhouses were combined and expanded with the help of Arlene Matzkin of Friday Architects to create a 5000-square-foot home on a charming street in the Rittenhouse Square area. The new single family home combines the historical charm of the buildings with modern, state-of-the-art interiors designed by designer Daniele Colonna. A large eat-in kitchen featuring custom cabinetry, granite countertops and glass tile splashes opens onto a loft-style living and dining room. The mahogany floors and stainless steel railings add a richness to the open floor plan. The bathrooms feature glass tiles, limestone and marble. A new sunroom opens onto a green meadow and a roof-top deck with spectacular views of the Philadelphia skyline.
