Carpenter Center for the Visual Arts at Harvard.

Harlow persuaded his father, Alfred St. Vrain Carpenter, Harvard (1905), to fund the building of a visual arts center at Harvard.

During the mid-1950s, the idea of creating a place for the visual arts at Harvard began to take shape. A new department dedicated to the visual arts was created, and the need for a building to house the new department arose. A budget was set for $1.3 million, and the proposal was included in a Harvard fundraising program. The project immediately elicited a response from St. Vrain Carpenter, an alumnus who supplied $1.5 million for the proposed design center.[2] The donation propelled the project forward, and the Committee for the Practice of Visual Arts began to look for an architect to undertake the project. Originally, the committee had recommended that the building be designed by "a first rate American architect" who would be in the company of Charles Bulfinch and Walter Gropius, among others. However, Josep Lluís Sert, who was at the time Dean of the Graduate School of Design and chairman of the committee suggested that his friend and previous collaborator, Le Corbusier, be asked to design the building. Delayed due to scheduling and payment conflicts, Le Corbusier eventually accepted and made his first of two visits to Cambridge in 1959.

After much debate, a site was chosen between Quincy and Prescott Streets, abiding by the original proposal for the building.The allotted space was quite small, so the completed building presents itself as a compact, roughly cylindrical mass bisected by an S-shaped ramp on the third floor. Le Corbusier's earliest design showed a much more pronounced ramp that further separated the two parts of the central mass. However, the early design created the problem of too much disruption of the central mass. This problem was reconciled by using a pinwheel effect so that in the finally executed design, the two halves meet at a vertical core that houses an elevator. The concrete ramp is cantilevered from this central spine and stands atop a few pilotis. The landing at the top of the ramp is located in the core of the building and leads to various studios and exhibition spaces seen through glass windows and doors, providing views into the building's instructional and displaying functions without interrupting the activities in progress.

The exterior of the Carpenter Center presents itself very differently from different angles. From Prescott Street looking toward the curved studio space, one can see the brise-soleil that are placed perpendicular to the direction of the central portion of the ramp, making only their narrow ends visible from the street. The Quincy Street view, however, reveals ondulatoires on this studio's exterior curve, which interfere with the building's curve less than the brise-soleil do on the opposite side. On the ramp from Quincy street just before entering the building, one sees grids of square and rectangles of the windows, brise-soleils, and studio spaces, rather than the curves of the two halves of the building.
