Arena Stage’s Mead Center for American Theater in Washington, D.C., used engineered wood as part of the building’s primary structure—not merely as interior finish. Eighteen large parallel strand lumber (PSL) columns carry both the transparent façade and steel roof trusses, while PSL muntins, support arms, and spring-loaded stainless-steel cables support the glazing. The result was a 500-foot cantilevered roof and a large, acoustically separated glass enclosure around the existing theaters.
The project, completed in 2010, is a historical example of how a timber façade can be engineered to handle gravity, wind, movement, fire review, acoustic requirements, and complex connections. The dimensions, test procedures, cost comparison, and carbon figures below are reported by the Building Enclosure case study attributed to US WoodWorks; they are not an independent engineering review.

What was Arena Stage’s Mead Center designed to solve?
Arena Stage’s earlier Washington complex contained the Fichandler and Kreeger theaters, both treated as historic structures. The organization needed additional space, updated technical facilities, and better separation from outside noise. Aircraft activity near Reagan National Airport and nearby road traffic could interfere with performances.
The design team kept the existing theaters, wrapped them in a new insulated glass wall, and used the space between the old buildings and the enclosure for a lobby and offices. A third, smaller theater—the Cradle—was added within the composition. The completed center enclosed about 200,000 square feet beneath a large roof, creating a new public interior without demolishing the historic theater volumes.

Bing Thom Architects led the design. Fast+Epp served as base-building structural engineer, Clark Construction was the general contractor, and StructureCraft Builders Inc. designed and built the specialty timber façade. The case study reports a 500-foot cantilevered roof, a façade extending roughly 650 feet, and a project completion date of 2010.
How did the timber façade carry both glass and roof loads?
The perimeter structure uses 18 elliptical PSL columns spaced 36 feet apart. Each column is reported as 45 to 63 feet tall. Unlike a decorative wood screen, these members were part of the load path: they supported the glass wall and also received loads from steel roof trusses, some as long as 170 feet.
The case study reports roof reactions of up to 400,000 pounds at the columns. The central Cradle theater walls helped brace the roof, which allowed the designers to avoid diagonal cross-bracing along the long, transparent façade. That decision preserved the open visual character of the lobby while making the theater mass part of the building’s lateral-stability strategy.
The columns were described as unreinforced solid engineered wood, with no internal steel support. Their elliptical shape reduced their apparent bulk while still providing the section properties needed for bending and compression. The structural concept therefore combined a relatively light-looking perimeter with a very substantial roof and façade load path.
What is PSL, and why was it suitable here?
Parallel strand lumber is made from long veneer strands aligned in the same direction and bonded with adhesive. The material is commonly used for long-span beams, heavily loaded columns, and members that need high bending strength. Those characteristics made it a candidate for tall, slender columns exposed as part of the architecture.
For Arena Stage, PSL slabs were laminated into billets. The billets were shaped on a lathe, sanded, and clear-coated before installation. This process produced the smooth, elliptical columns required by the design while retaining the predictable, engineered properties needed for structural calculations. It also allowed the timber to be fabricated as a precise architectural element rather than assembled as a conventional rectangular post.
Using PSL did not eliminate the need for steel or other materials. Steel roof trusses, aluminum connection plates, ductile-iron castings, glass, and stainless-steel cables all form part of the system. As StructureCraft business development engineer Brian Woudstra explained in the case study, “The beauty is that wood works well with other materials—for Arena Stage, we integrated wood with the steel roof trusses and cables, with the aluminum connection plates, with the ductile iron castings and the glass curtain wall, and with other connections.”

How were the glass panels supported and allowed to move?
The façade includes 324 custom PSL muntins and 216 support arms. These timber members carry the glazing’s weight and transfer forces back to the perimeter columns and roof-and-floor structure. Fifty-four spring-loaded stainless-steel cables run between the roof and floor, adding support while allowing the façade to accommodate movement rather than forcing brittle glass connections to absorb it.
The cables were pre-tensioned. The case study says that, as the glass was installed and loads were applied, the glazing and cables settled into their intended positions. This sequence matters because a transparent wall attached to a large, flexible roof must be designed for deflection, not only for its unloaded geometry.
Fast+Epp principal-in-charge Gerry Epp described the approach as follows: “We engineered an economical system for a sensitive glass façade subject to large out-of-plane deflections using spring-loaded cables and wood muntins, which carry the dead load of the glass.” He also reported that the team developed and tested a nearly invisible connector for the muntins, which had to carry bending moments as well as axial forces.
The system was therefore more demanding than a standard curtain wall hung from a rigid steel frame. Connections had to transfer multiple force types, remain visually discreet, and tolerate movement from wind, roof deflection, fabrication tolerances, and erection. The timber members were structural framing, glazing supports, and part of the architectural expression at the same time.
How was the unusual structure verified before construction?
The case study reports two major verification exercises. First, the team produced a scale model and conducted a wind-tunnel test in London, Ontario. Second, StructureCraft built a five-panel-wide, full-height façade mock-up that Clark Construction tested in a Pennsylvania laboratory under hurricane conditions.
Those tests were used to refine connection details and erection procedures. They should be understood as verification steps reported by the project team, not as a substitute for an independent review of the underlying engineering reports. The published case study does not reproduce the test data, acceptance criteria, or laboratory reports.
Fast+Epp project manager Julien Fagnan summarized the modeling challenge in the source: “First principles are always important, but this type of complex system required careful modeling.” In practice, the combination of flexible roof framing, spring-loaded cables, wood members, glass, and concealed connectors required the team to study how the parts behaved together rather than checking each component in isolation.

How were the PSL columns and façade parts fabricated?
Fabrication was tied to a parametric three-dimensional model. The model coordinated the changing geometry of the elliptical columns, muntins, support arms, connection hardware, and glazing interfaces. Components were prefabricated off site, reducing the amount of shaping and fitting required around the operating theater complex.
The muntins and support arms used a tight-fit dowel connection system. Because these joints had to resist both axial force and bending while remaining nearly invisible, their tolerances were significant. The full-height mock-up helped the contractor and specialty fabricator establish an erection sequence before the production façade was installed.
Off-site fabrication did not make the project simple. It shifted effort toward digital coordination, machining, quality control, transport, and field alignment. The reported process illustrates why a highly customized timber-and-glass enclosure needs the architect, structural engineer, general contractor, specialty fabricator, and glazing team involved early.
How did the design address theater acoustics?
The new glass enclosure was intended to provide acoustic separation from aircraft and road traffic while creating shared lobby and office space around the existing theaters. The acoustic goal influenced the overall building form: the insulated glass wall created a protective outer envelope instead of leaving the historic theater volumes exposed directly to outside noise.
What’s actually slowing this PC down?
Pick the symptom - the matching free tool is one click away.
Inside the Cradle theater, the case study describes a poplar slat wall intended to absorb and disperse sound in the oval-shaped room. Stained poplar was also used for the lobby ceiling soffit, where it helped absorb sound. These interior timber surfaces complemented the structural PSL façade but served a different purpose. The PSL columns and muntins carried loads; the slatted and stained poplar elements helped shape the acoustic environment.
What fire and life-safety questions did exposed timber raise?
District of Columbia code officials raised concerns about exposed heavy timber. The project team responded with a fire report and smoke study and used computer modeling and char analysis in discussions with officials. Charring analysis is relevant to heavy timber because a predictable char layer can protect the remaining wood section for a period of time, but the case study does not provide the underlying calculations or independently verify the authorities’ conclusions.
For a contemporary project, the practical lesson is that exposed structural timber must be addressed through the applicable building code, fire-resistance design, smoke movement, egress, fire-service access, and approval process. A successful precedent does not automatically establish approval for another building, occupancy, jurisdiction, or timber product.

Did the integrated wood system cost less than a conventional alternative?
The case study reports that the integrated system cost less than the conventional alternative considered for this project. That alternative used steel columns to support the roof and a separate aluminum curtain-wall system. The comparison is project-specific; it does not prove that timber façades generally cost less than steel-and-aluminum assemblies.

One set of columns carried both roof and façade loads, the timber framing formed part of the visible architecture, and the custom system avoided a separate line of façade structure. Against those benefits were the costs of engineering, digital fabrication, mock-up testing, specialized connections, transport, and erection. On another site, different spans, labor markets, code requirements, fire strategy, or procurement routes could change the balance.
What carbon benefit did the case study report?
The US WoodWorks case study, reproduced by Building Enclosure in 2014, reports 8,800 cubic feet of panel and engineered wood products in the project. It estimates that the wood stored 215 metric tons of carbon dioxide and that using the wood avoided 460 metric tons of greenhouse-gas emissions. The source combines those figures into a total potential carbon benefit of 675 metric tons of CO₂.
The same source equates that potential benefit to taking 129 cars off the road for one year or supplying the energy to operate a home for 58 years. Those are the source’s equivalencies, not independently checked conversions. The published article does not include enough of the life-cycle inventory, product-boundary assumptions, transportation data, end-of-life treatment, or calculation methodology to independently assess the estimates.
Accordingly, the figures are useful as source-attributed project reporting, but they should not be presented as a universal carbon advantage for every timber façade. A current project would need its own material quantities, environmental product declarations, structural substitutions, construction impacts, and end-of-life assumptions.

Arena Stage demonstrates that engineered wood can be a primary structural participant in a transparent enclosure when the load path, movement strategy, connections, fabrication, and approvals are designed as one system. The project did not treat timber as a finish applied after the structure was complete. Its PSL columns, muntins, and support arms were integrated with steel roof trusses, cables, aluminum plates, castings, and glass.
It also shows why visual simplicity can conceal technical complexity. The finished façade appears open and lightly detailed, yet it carries large roof reactions, supports heavy glazing, accommodates out-of-plane deflection, and avoids visible cross-bracing. Wind-tunnel work, a full-height hurricane-condition mock-up, parametric fabrication, and a carefully sequenced erection process were all reported parts of making that appearance possible.

For designers considering a similar approach, the transferable principle is not a particular column size or cable count. It is the need to establish performance requirements early: structural load sharing, acceptable movement, glass limits, acoustic targets, fire strategy, connection visibility, inspection access, fabrication tolerances, and the authority-having-jurisdiction’s approval path. Arena Stage is a valuable precedent, but its custom details remain specific to the Mead Center.

Frequently Asked Questions
Is parallel strand lumber the same as ordinary solid-sawn timber?
No. PSL is manufactured from long veneer strands aligned parallel and bonded with adhesive, giving it engineered and relatively consistent structural properties. Its manufacture also permits large, shaped members such as Arena Stage’s elliptical columns rather than limiting the design to naturally available solid-sawn sections.
Why did the façade need spring-loaded cables instead of only rigid mullions?
The cables helped support the glazing while accommodating movement from roof and façade deflection. A cable-supported arrangement can share load without forcing every glass connection to behave as if the surrounding structure were perfectly rigid.
Can the Arena Stage carbon estimate be used in a life-cycle assessment for another project?
Not without rebuilding the calculation with that project’s quantities, products, transport, construction impacts, and end-of-life assumptions. The published Arena Stage figure is a 2014 case-study estimate, and the article does not provide enough underlying methodology to reproduce or independently validate it.
What should a team investigate before proposing an exposed timber curtain wall?
Start with the authority-having-jurisdiction’s fire and smoke requirements, then define allowable façade movement, glass limits, connection inspection, fabrication tolerances, acoustic targets, and erection sequencing. A project-specific mock-up and structural and wind analysis may be needed before finalizing the details.
