    Riverdale Bronx, NY

    The topography is very prominent in this area of the Bronx. Outcroppings of Fordham Gneiss are common, there are beautiful views of the Hudson River and New Jersey Palisades to the West. The property is terraced and there are many large trees.

    The height of the house is lower along the street and rises in height to the West. The main door is within an entry courtyard separated from the street.

    The construction is a combination of steel frame and wood frame. Structural concrete floors incorporate a hydronic radiant heat system. The cladding is slate tiles, the tiles are installed using a traditional system of wood battens. The roof surfaces are planted with an extensive green roof system. Interior finishes are waxed concrete floors, red birch wood floors and ceilings.

    There is a cooling tower which creates a stack effect for whole house ventilation. The cooling is augmented with a fan when needed. The ventilation grilles are visible on both on the Street elevation and the North elevation.
