An enhanced understanding of African-American history and culture in New York City is bound to emanate from the Weeksville Heritage Center just completed by Long Island City, N.Y.–based Caples Jefferson Architects. And the source of this enlightenment is found in four 19th-century structures whose very existence was largely unknown until the late 1960s.

These modest wood-clad houses near the center of present-day Brooklyn are all that remain of the African-American community of Weeksville, which once included hundreds of households, with related churches and schools. In 1968, historian James Hurley was leading a Pratt Neighborhood College team studying old city neighborhoods. Alerted by archival material on Weeksville, he flew over its likely location and spotted the houses—three of them hidden mid-block, sited at an angle to the street grid and surrounded by rowhouses that had engulfed the area as it became urbanized. The fourth and latest of these houses, aligned with the street grid, still had descendants of the original residents living in it.

The houses date from 1838—about a decade after New York’s last slaves were freed—to 1883. They were designated New York City landmarks in 1970 and subsequently listed on both the state and national historic registers. An organization, now known as the Weeksville Heritage Center, was established to turn the houses and adjacent property it acquired into a functioning historic site. With funds from private and public sources, the houses were restored in the early 2000s by the architectural firm WASA/StudioA. Today three of them are open for tours, with furnishings tracing domestic life here over the decades up to the 1930s. On the surrounding grounds, school children explore such skills as growing vegetables, keeping bees, and raising ducks.

To offset the cool tones of the slate and glass, the bulk of the center’s low-slung volume is clad in warm ipe siding from General Woodcraft. The metal cornice was produced by Revere Copper. Glazing in the recessed entry portico allows views clear through the building.

At the time of the restorations, a master plan by WASA/StudioA proposed a new education building for interpretation of the site and related history. Since the city was supporting the project financially, the commission for the new building was awarded through the Design Excellence process of its Department of Design and Construction. In 2003, Caples Jefferson Architects won the commission.

From the outset, it was agreed that the new construction was to be at the southern and eastern edges of the site, farthest from the historic houses, leaving a swath of open landscape to represent their original rural setting. This had the added benefit of allowing the new building to define the site’s boundary, and to adopt the streetfront configuration common to its modern day, gridded, urban context. The project’s planning also took into account a historic route, Hunterfly Road, that once crossed the site at an angle to the current grid and toward which the community’s houses were oriented. The approximate path of this road is only known from historical maps—traces of it through this property had been erased by later dense construction. The architects placed the entrance to the new building approximately on this road’s path, so that the initial viewline of the houses through the center’s glazed walls roughly follows that of the historic throughway. But lacking archaeological evidence, the old route has been treated as a “ghost road,” acknowledged by a cut through a low mound in the new landscaping and emerging as a footpath near the houses.

Caples Jefferson’s initial building design proposed a series of volumes with subtly convex walls and roofs, intended as “an evocation of traditional building forms from West Africa,” says principal Everardo Jefferson, AIA. These volumes were separated by transparent links that allowed views into the site from the street. The scheme received an award from a National Organization of Minority Architects jury, but it did not please the city’s Art Commission (since renamed the Public Design Commission), whose approval was required for public funding. One of the commissioners protested that “he thought we had gone beyond such cultural evocations,” recalls principal Sara Caples, AIA.

  While not fully agreeing, the architects and their clients set to work on a scheme that is more clearly of its own place and time. And the crisply geometrical design they developed not only suited the client, but was warmly endorsed by that same commission. Once it accepted the final scheme, the commission became, say the architects, “the guardians of the design,” countering challenges by the other reviewing groups.

Despite the rejection of large-scale references to West African design, Jefferson “refused to give up on references to African origins,” he says. Into the building’s otherwise crisply geometrical volumes, the firm introduced patterns adapted from those sources. He was determined that none of these patterns were to be literal copies or superficially applied, but rather “embedded in the construction process.” Examples of such treatment are seen in the layout of slate slabs on the exterior walls, the woven bronze security screen at the entrance, and the cast-iron fencing around much of the property. Frit designs on the glazing over circulation spaces project their patterns—which change with light conditions—onto other surfaces. The subtlety of these patterns is proven “when visitors don’t notice them till they’re pointed out,” says Jefferson with pleasure.

Within the 19,000-square-foot structure, all of the public facilities—which include classrooms, workshops, a 700-square-foot skylit gallery, and a 200-seat performance space—are located on the ground floor. These are reached by generous passages with fully glazed walls and roofs—21st-century interpretations of the traditional pergola—that offer continuous views of skies and landscape. Offices and a conference room are on the second floor of the main block. At the far western end of the building, a secluded library mezzanine offers elevated views back over the complex.

The building is sustainably designed with a goal of LEED Gold, and careful consideration was given to systems and materials. Geothermal wells provide sources for heating and cooling. All of the glazing is insulated, and most is low-E-coated to reduce heat gain and glare—except where it is left clear to maximize views through the building into the site. The architects specified sustainably harvested wood, such as the ipe wood siding and the Douglas fir in the exposed roof decking over upper-floor spaces. Much of the steel in the framing and ceiling systems has recycled content.

Summing up the product of her firm’s decade-long effort, Caples is pleased that this is a building that people can love “whether or not they are sophisticated about design,” she says. And given the essential support of the project “by people’s donations and public funds,” she’s satisfied that, in the end, the result meets an imperative “to give back value.”

Much of the pergola glazing, which was sourced from fabricator JE Berkowitz, is clear vision glass. To minimize glare and heat-gain, a frit was applied to the ceiling panes.
