The commons provides spaces for encounters that strengthen and further the best interest of the community - without a consumer agenda. This is a place where both formal and informal events and progress take place, notably civic engagement. South Lincoln has no platform where community members can exercise democratic processes without hidden regulations or a destructive culture. This proposal will be a space promoting debate and conversation in a healthy and productive way. The space will work to unify and stimulate a rather dull and disconnected area.

The idea of a social condenser to fulfill these goals has been explored time and time again but has yet to realize a form that’s successes lasts longer than just a brief moment in time. The works of infamous social condenser proponents such as Moisei Ginzburg and Rem Koolhaas can point us closer to achieving this form by studying their downfalls and improving upon them.

In order to see these goals to fruition, we are striving to make the commons a central hub for the community, free of intimidation and polarization. This process will function best in an environment that finds an appropriate balance between energetic and grounded. Users will be immersed in the clashing of a multitude of programs in the center commons with the intentional lack of seclusion, physically and visually. Reconfigurable dividers provide surfaces to project media upon and new divisions of space to aid in these processes.

The circular form is utilized because it most effectively emphasizes the intersections of public space through a circulation ring in the center of that bleeds into the various programs. This wide intersection allows for various configurations hosting conversation and debate unseen in previous condensers, specifically promoting democratic processes. Within the intersection, a central depression in the floor functions as a versatile seating and gathering area. Reconfigurable dividers provide surfaces to project media upon and new divisions of space to aid in these processes. The asymmetrical sectored circle also lends itself to non-hierarchical organizations and intriguing push and pull distortions complimenting of environmental and view framing concerns. Undulating floors work to further interactions between the program sectors. This strategy is continued into the landscape, extending main formal lines to create gathering spaces varying in size and program.

1. A circular building plan is placed in the Northwest corner near the two major street frontages within the zoning corner setback. This leaves room for parking spaces, gathering recreation areas, and the service entry which their locations are based on similar typologies that are adjacent to the site.
4. The building height is lower on the Southside of the building and higher on the Northside to manage solar heat gain whilst allowing in natural light. The center is kept separate from the main roof to allow light into the center of the building. These varying heights keep the human scale in mind and correlate with the program and user types.
2. The building program is orientated around the center of the circle to create the commons space, and radiated into the surrounding programs, allowing the entire building to function as a commons. This program organization allows the center to facilitate gathering and creates panoramic views into all of the primary areas and of the site.
5. A roof is added to provide shading for outdoor spaces. A colonnade is added around the perimeter of the building and skylight to provide structure, shade, and privacy. The column spacing opens up at access points and major views points. The colonnade not only unifies the partitioned circle, but allows the commons to extend to the exterior.
3. Parts of the circle recede at various distances from the encompassing walkway to create opportunities for exterior gathering, to aid in accessibility + wayfinding, and to provide self-shading. These lengths are based on whether the programs are primary, secondary, tertiary, and quaternary spaces.

6. The exterior site is seen as an extension of the building. This is done by using the primary design moves and program types within the site. The exterior program is created to provide a range of programs with a variety of scales and spatial types. There is access to the site and building from all sides.

The main elements of the exterior and interior building envelope are a monotone pallatte of taupe expressive sand cast concrete, jagged at an oversized scale on the exterior, and contrasting smooth concrete on the interior, with a radiant velvet finish.

Concrete is the only material that will be altered based on interior vs. exterior placement. The exterior and interior sides of the sandwich wall construction will be a combination of tilt-slab concrete and cast-in-place concrete. Many of the walls will be load-bearing shear walls, providing strength and insulation. In the curtain wall, unitized glazing was chosen to diminish joints in windows in order to emphasize the concrete masses; in other words, create a natural feeling of open-air solids and voids.

While the building form is contemporary and of its time, the materials chosen would be reflective of vernacular traditions for both civic buildings and local use of materials. The primary material that will be used within the building is concrete, and the secondary material is copper colored aluminum. Concrete is a historic building material that has a long and rich past of being used within civic buildings. The use of concrete for the proposed library, and its monolithic qualities, creates an innate sense for users to make conclusions that this is a civic building. Concrete is a strong material and has a long lifespan which is valuable when being used within a civic center that must stand the test of time. There will be a mix of smooth and rough forms and finishes of concrete that will be used both on the interior and exterior of the building. Joints in the concrete are hidden to give the feeling of a carved out structure. Copper-colored aluminum will be used for accents such as possible dividing structures, window/door mullions, and signage on the interior and exterior of the building. This project will use these materials along with a variety of textures and arrangements to call out sectors, spaces, and atmospheres within the building. The majority of the materials will be orientated horizontally to give a low profile quality to the building and for it to match the human scale. The mixing and intersections of the materials provide a connection to the mixing and intersections of the commons with other programs. The chosen materials will also have a hand in building sustainability and energy savings.

Moments of significant expression lie in the exterior columns and both floor to wall and ceiling to wall connections. This is an important detail to resolve in line with the proposal’s main goals, Concrete Texture, Finish especially to expose the structure and celebrate the strong and solid qualities of Color, civic architecture. Light Taupe, Acidmullion Etched, Velvet Finish (Flat) The columns will be entirely cast in place concrete that give the appearance of a structural Light Taupe, Trowel, Velvet Finish (Flat) when interfaced with the curtain walls. In reference to the wall connections to the floor and ceiling, Taupe, Acid Etched, Velvet Finish (Jagged) there will be a divot in the vertical direction to give the appearance that the floor Light and ceiling are Light Taupe, as Medium separate parts. This furthers our goals of creating a commons and utilizing the commons a Exposed civicAggregate, Polished Finish (Flat) Light Grey, Sand Blasted, Velvet Finish (Flat) agent in that the floor appears as a durable platform for the community.
