Although a less effective example of the planning and the organization of circulation that Pratt was so interested in, the grand two-story staircase and the use of central corridors on each floor meant that suites of apartments could be separated and prevented private rooms having to act as passageways through the house. Most probably inspired by his travels, the house is a mix of Italian, French, Dutch and English architectural ideas and includes features such as the rooftop platform and cupola, dormered attics, half-sunk basement, astylar elevation, and symmetrically placed apartments. Palladian details are evident in the windows and cornices, and the "double-pile" plan is derived from Jones' Queen's House in Greenwich (1614–1617). The prominent chimneys and dormers, and the rusticated basement, are more French in inspiration, while the equal proportions of the storeys were an innovation, compared to the Palladian manner of emphasising a piano nobile, or principal floor.
