House 4 is a smaller, two-story version of House 3. As in House 3, private outdoor space is created by placing the main portion of the house along the northern edge of the property. A landscaped garden, running along the south side of the site, is subdivided by the louvered glass walls of the living room.

House 4 includes three large bedrooms with private baths and balconies, all located on the second floor. The first floor living spaces are oriented to the garden courts and to the Rio Cervantes Waterway. An open central stair flanks the entry hall and becomes a defining feature in the flow of public space. Another feature of the ground floor design is the connection of the living and dining rooms with a diagonal glass wall. The diagonal glass wall and its corresponding rooflines are connected to the front and rear entry canopies that link the two garden courts.

The house incorporates sun shading with exterior horizontal louvers on the southern exposures and privacy shading with vertical louvers on the more public eastern elevations.

Other features include a canal-side swimming pool and a 1,500 square feet rooftop terrace, accessible from an open second-floor stair.
