After all of the back and forth about the future of D.C.’s Martin Luther King Jr. Library—particularly, the controversy over adding several stories of mixed-use development—it seems that the architects have finally been able to make some progress toward a vision of what the finished overhaul will actually look like.

Although still preliminary, DCPL released a new set of renderings today from architects Martinez + Johnson and Mecanoo that show just a single extra floor, rather than several levels for office or apartment space, and a ground-level cafe, where retail had previously been proposed, for the historic Ludwig Mies van der Rohe building.

The renderings also show plans for an interactive children’s area, a “maker space” replete with tools and workbenches, and a performance area that can also be used for exhibits.

The design still must go through a federal review process, and DCPL hasn’t yet picked a place to host an interim central library, Washington Business Journal reports.
