Mass timber architecture is moving beyond the familiar beam-and-column floor plate through three related innovations: hybrid mass-timber/steel frames, connections that reduce or remove steel reinforcement, and two-way-spanning floor or roof panels. Together they give designers more choices about grids, exposed wood, connection detailing and beam-free space, but they do not offer a universal cost or carbon solution. The best option depends on panel dimensions, fire and vibration requirements, available fabrication, connection engineering and the building’s plan.
These approaches and the projects below come from Tom S. Chung’s May 2024 article in Building Design + Construction. Its project statuses, production counts and height records are historical snapshots, not verified 2026 updates.

The three approaches are: retain a conventional steel frame while replacing concrete-and-metal-deck floors with cross-laminated timber (CLT); engineer connections that use much less steel or, in some cases, no steel connectors; and design CLT or mass-plywood panels to span in two directions so floors and roofs can bear directly on columns.
| Approach | Primary design opportunity | Main constraint to resolve |
|---|---|---|
| Mass timber–steel hybrid | Familiar grids and beam depths with wood floor panels and potentially exposed ceilings | Coordination among steel, panels, fire protection, acoustics and vibration |
| Reduced-steel or all-wood connections | Less visible steel and a lower-steel connection strategy | Bespoke engineering, fabrication complexity and cost |
| Two-way-spanning panels | Point-supported, beam-free floors or roofs | Panel width, manufacturing capability, loads, deflection and punching-shear design |
How does a mass timber–steel hybrid work?
A hybrid system keeps a steel frame’s familiar column grid and beam depths while using CLT floor panels instead of a composite metal deck and concrete slab. Chung cites a 30-by-30-foot steel office grid as an example of a layout that can be retained while changing the floor assembly. Where the structure and code strategy permit, the underside of the CLT can become a visible wood ceiling rather than being concealed behind a suspended system.

The practical attraction is interchangeability. Engineers and contractors accustomed to steel framing can continue to coordinate columns, beams and floor openings in a recognizable way, while the panel supplier provides a largely prefabricated floor element. The choice also affects the whole assembly: acoustic layers, topping slabs, fire-resistance strategy, mechanical distribution, moisture protection and the tolerances between steel and timber all have to be resolved early.
Which projects illustrate the hybrid approach?
The examples identified in the source are 901 East Sixth in Austin; Engineering West 2 at Penn State; North Hall Residence at the Rhode Island School of Design; and Cornell’s CIS building. They are examples of the design direction, not a measured comparison of cost, schedule, embodied carbon or operational performance.

A hybrid floor can be especially useful when a project has a planning module inherited from commercial steel construction or when the owner wants a wood finish without committing every part of the gravity system to timber. It may be less advantageous where panel spans, floor-to-floor heights, vibration limits or fire-protection requirements force extensive additional layers that erase the intended simplicity.
Can mass timber connections eliminate steel reinforcement?
Some designers are developing connections that transfer forces through timber components and geometry rather than relying on conventional steel plates, rods or brackets. The goal is not merely visual: reducing steel can change the detailing sequence, the amount of exposed hardware and the material mix. However, Chung characterizes all-wood connection approaches as bespoke and expensive, so the concept should be treated as an active design direction rather than a proven general cost reduction.

All-wood joints require careful attention to splitting, crushing, withdrawal, rotation, moisture movement, fire performance and installation tolerances. A connection that works in a laboratory or a singular architectural project may not be economical at a different scale, species, load level or fabrication plant. The engineering package should document load paths, concealed fasteners if any, inspection requirements and replacement or repair procedures.
What are Tamedia and Heartwood examples of?
Chung points to Tamedia in Zurich as an example of an advanced timber connection strategy and describes Heartwood, a Seattle workforce-housing project he says was completed in 2023, as designed with no steel connectors. He credits atelierjones with the design and Timberlab with detailing. The article presents Heartwood’s approach as promising for cost efficiency, but it does not establish a measured result that applies to every mass-timber building.

1Clear out junk files and repair common Windows errors2Fix the driver behind crashes, sound loss and screen glitches3Repair Windows errors before they cause bigger problemsFor most projects, the realistic question is not “wood or steel?” but where steel is structurally or economically justified. A hybrid connection may use small, standardized steel fasteners in concealed locations while reserving all-wood details for repeated, accessible joints. Early prototyping, mock-ups and shop-drawing reviews are important because connection tolerances often govern the erection sequence more than the panel itself.
How do two-way-spanning CLT and mass-plywood panels create beam-free space?
Conventional CLT floors are commonly treated as one-way elements supported by beams or walls. Two-way panel action allows loads to travel in both directions, opening the possibility of point-supported floors and roofs in which panels bear directly on columns. That can remove deep beams and simplify a ceiling plane, but the system is governed by panel geometry, connection behavior, deflection, vibration and punching around supports.

Chung cites Brock Commons Tallwood House at the University of British Columbia, where repetitive CLT panels are supported on glulam columns at spacing of about nine feet. He notes that the spacing reflects panel-width constraints and suits the narrow student-room plan. The example shows both the opportunity and the limit: two-way behavior can enable a beam-free layout, but manufacturing dimensions and the room module still shape the architecture.
The KPNC Environmental Education Center at Auburn University is described as exploring cantilevered CLT panels on glulam columns for a beam-free roof. Cantilevers increase demands at the support and require a detailed check of rotation, connection stiffness, uplift, weathering and construction-stage stability. A roof that appears structurally simple may therefore require more sophisticated analysis and temporary works than a conventional beam-supported roof.
What must be checked before choosing point support?
- Panel capability: Confirm the product’s thickness, layup, maximum practical dimensions, openings and available machining.
- Support behavior: Design the column-to-panel interface for compression, shear, moment transfer, uplift and punching or localized failure.
- Serviceability: Check deflection, vibration and acoustic performance under the actual occupancy and finishes.
- Construction sequence: Verify temporary bracing, lifting points, weather protection and access for inspection and fastening.
- Fire and durability: Coordinate charring assumptions, encapsulation where required, moisture control and long-term movement.
How do the three approaches compare?
They solve different problems rather than forming a simple ranking. Hybrid framing prioritizes compatibility with familiar structural grids; reduced-steel connections prioritize material and visual refinement at the joints; two-way panels prioritize spatial freedom and fewer beams.
| Decision axis | Hybrid steel–timber | Reduced-steel connections | Two-way panels |
|---|---|---|---|
| Best fit | Projects with established steel planning modules | Architecturally expressive joints or repeated connection families | Beam-free floors, roofs or point-supported layouts |
| Coordination priority | Steel tolerances, floor build-up and exposed ceilings | Joint engineering, fabrication and erection tolerances | Panel dimensions, column spacing and support zones |
| Evidence in the source | Four cited building examples | Tamedia and Heartwood examples | Brock Commons and Auburn’s KPNC exploration |
| Evidence limitation | No apples-to-apples cost or carbon comparison | All-wood solutions described as bespoke and expensive | Spacing and form remain constrained by panel capability |
Why is mass timber expanding?
Chung reports that more than 1,000 mass-timber buildings were planned and hundreds realized when his May 2024 article was published. He also reports Wood Innovation Network figures showing zero U.S. building-grade CLT fabrication plants a decade earlier and more than a dozen CLT plants in North America at publication, alongside major European producers establishing a regional presence. Those figures describe the market at that date, not a current 2026 census.

The article records a related rise in professional interest: fewer than 300 people attended the International Mass Timber Conference in 2016, compared with more than 3,000 attendees the prior year (2023). It also notes that North America’s tallest mass-timber building rose from eight stories in 2014 to 25 stories at the time of publication. Height records and attendance counts should not be treated as proof that one structural system is universally better; they show how quickly the field’s capacity and visibility were changing.
“The objective is to expand mass timber architecture beyond the conventional use of a one-way floor span supported by beams and columns.” — Tom S. Chung, FAIA

How should an owner and design team select an approach?
Start with the project’s non-negotiables, then test each structural concept against them rather than selecting a system by appearance alone.
- Set the planning module. Record column spacing, room widths, façade rhythm, service zones and any existing steel or concrete constraints.
- Define the visible-wood goal. Decide whether wood is exposed, partly exposed or fully encapsulated; this affects fire, acoustics, finishes and inspection.
- Engage the fabricator early. Confirm panel sizes, CNC capabilities, lead times, species or layups, allowable openings and moisture-protection procedures.
- Compare complete assemblies. Include topping, membranes, acoustic treatments, fire protection, connectors, temporary works, crane operations and site tolerances—not just the timber volume.
- Model serviceability and life safety. Require documented checks for vibration, deflection, fire resistance, egress, progressive collapse where applicable and durability.
- Plan procurement and substitutions. A design dependent on one panel size or one connection fabricator needs an explicit alternative before construction documents are issued.

Frequently Asked Questions
Is mass timber always cheaper than steel or concrete?
No. The cited article supplies no apples-to-apples cost study. Prefabrication and lighter assemblies may help a particular project, while fire protection, acoustic layers, specialized connections, transportation and erection can add cost.
Can CLT panels be used without a concrete topping slab?
Sometimes, but the decision depends on fire, acoustics, vibration, moisture, finish and structural requirements. A topping slab may be part of the required floor assembly even when CLT replaces the metal deck.
How far apart can columns be in a two-way CLT floor?
There is no universal spacing. Brock Commons is described with roughly nine-foot spacing, constrained by panel widths and its narrow student-room plan; another building may require different dimensions after engineering and fabrication review.
Are all-wood connections available as standard products?
The source characterizes all-wood connection approaches as bespoke and expensive. Standard steel fasteners or concealed hardware may still be selected for repeatability, inspection and code documentation.
