In the front of each house on the ground floor was a recessed window unconnected with the recessed doorways, formed by setting the inner external wall back from the outer face of the building.

This window looked out through an arched opening to the street, and was protected by a dwarf parapet or balustrade.

It was possible to set potted vines and flowers there, which was later done, giving a pleasant sense of greenery from the street, and to place a few chairs there, which were reached via heavily barred French casements.
On the ground floor of each house was placed a conservatory of flowers, facing each other, and in the yard, which was jointly used, a pool of white marble eight feet in diameter, with a marble Cupid upon which jets of water played.

The yard which was enclosed by a high but pierced wall of green-gray brick, especially burnt for the purpose the same color as the granite of the house, and surmounted by a white marble coping which was sown to grass and had a lovely, smooth, velvety appearance.

The two houses, as originally planned, were connected by a low, green-columned pergola which could be enclosed in glass in winter.
The rooms, which were now slowly being decorated and furnished in period styles were very significant in that they enlarged and strengthened Frank Cowperwood's idea of the world of art in general.
