Durham County Human Services Complex: Terracotta Rainscreen Façade
The Durham County Human Services Complex in Durham, North Carolina, brings public health, social services, mental health administration and other county programs together within a unified civic facility. Designed around a central courtyard, the building uses an Argeton terracotta rainscreen façade to establish a strong urban presence while creating a warm, welcoming environment for employees, visitors and community members.
Located on East Main Street in downtown Durham, the complex consolidates departments that had previously operated from several separate and inadequate buildings. The new facility improves coordination between county agencies while providing a more convenient and dignified experience for the thousands of people who use its services. The most frequently visited programs are located on the lower floors, while administrative departments occupy the upper levels. In addition to the primary public entrances, strategically located access points accommodate employees, specialized programs and other county functions.
How Does the Courtyard Design Support the Building’s Users?
The Durham County Human Services Complex was designed as a full-block courtyard building, with exterior façades facing the surrounding streets and an internal landscaped courtyard at its center. This O-shaped configuration gives the building a substantial civic presence while creating a protected outdoor gathering space within the urban setting. The courtyard provides employees and visitors with a quieter environment that contrasts with the activity of the surrounding streets.
Primary circulation areas face the interior courtyard, bringing natural light and exterior views into the building. Offices and public spaces are arranged to take advantage of daylight while maintaining privacy and security for people accessing health and social services. The central courtyard also serves as an architectural symbol of the project’s larger purpose by bringing multiple county agencies together around a shared, welcoming space.
Constructing the Complex in Two Phases
Because the new complex occupied the site of an existing Durham County public health facility, construction had to be carefully phased to keep essential services operating. The first phase was constructed along Queen Street, allowing Public Health employees to move into the new building before the older facility was demolished.
Following that move, the existing building was removed and the remaining portions of the complex were constructed along Dillard Street and Main Street. The interior courtyard was also completed during this phase. This carefully coordinated approach allowed Durham County to maintain access to critical public services throughout construction.
A Contemporary Interpretation of Durham’s Architectural History
The building’s massing fills the urban block, bringing the three- and four-story structure to the edges of the site. Its central courtyard and red terracotta exterior draw inspiration from the historic tobacco warehouses of downtown Durham, many of which are characterized by masonry façades and enclosed or semi-enclosed courtyards.
Rather than copying these industrial buildings, the design reinterprets their defining materials and forms for a contemporary civic facility. Red terracotta was selected as the primary exterior material to reference Durham’s traditional brick architecture while giving the complex a modern identity. The consistent use of terracotta also visually wraps the building’s different departments and program areas within a single architectural expression.
This unifying design reflects the purpose of the Human Services Complex. Public health, social services, mental health administration and other county programs are brought together in one location to create a more coordinated environment for care and community support. The terracotta façade gives this large and complex program a cohesive exterior identity.
How Does the Terracotta Rainscreen Façade Work?
A back-ventilated rainscreen system was selected to provide dependable thermal performance and help manage water and moisture within the exterior wall assembly. Unlike a barrier wall that relies primarily on its outer surface to resist water, a rainscreen allows moisture that passes through the exterior cladding to drain and evaporate through a ventilated cavity behind the panels.
The Argeton terracotta rainscreen system combines durable terracotta panels with an engineered support system. The noncombustible terracotta cladding protects the underlying wall assembly while providing the natural color, texture and visual depth needed to connect the contemporary complex with Durham’s historic masonry architecture.
The ventilated cavity behind the panels supports long-term moisture management, while the exterior cladding helps shield the air barrier and insulation from direct exposure to weather. Together, these components create a high-performance façade designed to support durability, energy efficiency and reduced maintenance throughout the life of the building.
Terracotta Rainscreen Design and Technical Support
Telling Architectural Systems worked closely with The Freelon Group, now part of Perkins&Will, during the design and specification of the terracotta rainscreen system. The collaboration included discussions about terracotta tile layouts, substructure requirements and the selection of materials for the complete exterior wall assembly.
This early coordination helped the design team integrate the façade’s visual pattern with its technical requirements. Terracotta panel dimensions, joint locations, attachment methods and transitions all needed to be coordinated with the building structure, insulation, air and moisture barrier, windows and other exterior components.
Todd Case, project architect with The Freelon Group, described the collaboration:
“The support we received from Telling has been very good throughout the project. We are particularly happy with the way the Telling technical people worked closely with the installer. The results have been very good so far.”
Installation Support from Design Through Completion
Telling’s technical services team also worked closely with Advanced Exterior Systems, the project’s façade installer, from the bid stage through construction. Regular coordination helped the project team address the building’s unique conditions and maintain the design intent as the terracotta rainscreen moved from drawings and specifications into installation.
A Telling Field Technical Manager visited the project site to provide guidance and oversight for the installation crews. This direct support helped the installer resolve technical questions, coordinate project-specific details and complete the specialty façade system successfully.
David Wheeler, COO of Advanced Exterior Systems, commented on the partnership:
“AES is very pleased with the quality and support given by the Telling group and Argeton as the manufacturer. The unique project conditions required a partner that could lead us through completion. Telling offered a professionalism and reliability which helped us deliver a quality product on time to our client. This result expands the possibilities of owners and architects to design their buildings incorporating specialty products with confidence.”
Sustainability and LEED Certification
Sustainable design principles influenced the building’s exterior enclosure, site planning and interior environment. The Durham County Human Services Complex earned LEED Silver certification, reflecting strategies intended to reduce environmental impact, conserve resources and create healthier spaces for employees and visitors.
The central courtyard, abundant natural light and access to exterior views contribute to a more comfortable interior environment. The terracotta rainscreen supports the performance of the building envelope by helping manage moisture and protect the underlying thermal and air-control layers. Other sustainable site features include water-efficient landscaping, native and urban-tolerant plants, stormwater-management measures and a cistern used to collect roof runoff.
At the Durham County Human Services Complex, sustainability also relates to the building’s social purpose. Many visitors come to the facility seeking services that help them care for themselves and their families. By providing comfortable, dignified and well-designed interior and exterior environments, the building supports both environmental responsibility and the long-term well-being of the community it serves.
The Completed Durham County Human Services Complex
Completed in 2013, the Durham County Human Services Complex demonstrates how a civic building can combine public service, sustainable design and a strong connection to its local architectural context. Its full-block massing reinforces the surrounding streets, while the protected courtyard introduces natural light, exterior views and landscaped gathering space into the center of the complex.
The red Argeton terracotta rainscreen gives the large facility a unified identity and provides a contemporary reference to the brick tobacco warehouses associated with Durham’s history. At the same time, the back-ventilated façade supports moisture management, thermal performance and long-term durability. The result is a civic complex that feels substantial and permanent without losing the warmth and accessibility appropriate for a community-focused building.

Frequently Asked Questions About Terracotta Rainscreen Façades
What is a terracotta rainscreen façade?
A terracotta rainscreen façade is an exterior cladding system in which terracotta panels are installed over a ventilated cavity, insulation and a weather-resistant wall assembly. The outer panels protect the building from direct weather exposure, while the cavity allows incidental moisture to drain and promotes ventilation behind the cladding.
What are the benefits of terracotta rainscreen cladding?
Terracotta rainscreen cladding combines durable exterior protection with natural color, texture and architectural flexibility. When incorporated into a properly designed wall assembly, the system supports moisture management, continuous exterior insulation and long-term façade performance. Terracotta is also noncombustible and can be used to create both traditional masonry-inspired façades and contemporary building designs.
How does a back-ventilated rainscreen manage moisture?
A back-ventilated rainscreen creates a cavity between the exterior terracotta panels and the underlying wall assembly. Water that passes through the panel joints can drain through this cavity, while air movement helps the assembly dry. This approach reduces reliance on the exterior cladding as the building’s only defense against water infiltration.
Can terracotta rainscreen be used instead of traditional brick?
Terracotta rainscreen can provide the warmth, color and visual character associated with traditional masonry while functioning as part of a lightweight, ventilated façade system. It is especially useful when a project calls for larger-format panels, custom layouts, continuous exterior insulation or a more contemporary interpretation of brick architecture. At the Durham County Human Services Complex, red terracotta connects the modern civic building with the historic brick tobacco warehouses of downtown Durham.
Is terracotta rainscreen suitable for civic and public buildings?
Terracotta rainscreen is well suited for civic buildings, schools, healthcare facilities and other high-use public projects because it provides a durable exterior finish with strong design flexibility. The material can help a large institutional building feel more welcoming while supporting the moisture-management and thermal-performance goals of the exterior wall assembly.
Can terracotta rainscreen support energy-efficient building design?
A terracotta rainscreen can contribute to an energy-efficient façade by accommodating continuous insulation outside the primary structure and helping protect the wall’s thermal and air-control layers. The cladding does not create energy efficiency on its own, but it forms part of a coordinated building envelope designed to reduce thermal bridging, manage moisture and maintain consistent interior conditions.
What design options are available with terracotta rainscreen panels?
Terracotta rainscreen panels are available in a range of colors, finishes, profiles, formats and installation patterns. Architects can use variations in panel size, orientation, joint alignment and surface texture to create façades ranging from uniform masonry-inspired elevations to highly articulated contemporary designs.
When should a terracotta rainscreen manufacturer or supplier become involved?
The terracotta rainscreen supplier should ideally become involved during the early design and specification stages. Early technical coordination can help the architect evaluate panel sizes, tile layouts, substructure requirements, attachment methods, wall transitions and integration with windows and other façade materials before construction documents are finalized.
What technical support does Telling Architectural Systems provide?
Telling Architectural Systems works with architects, contractors and façade installers throughout the design and construction process. Support can include assistance with terracotta panel selection, tile layouts, substructure coordination, wall-assembly considerations, project-specific details and installation guidance. On the Durham County Human Services Complex, Telling collaborated with both the architect and installer from design development through construction.
