StructureCraft

This new multi-use building in Abbotsford is the headquarters for the BC Conference of the Seventh Day Adventist Church. Nestled into the slightly sloping site by @sitelines_architecture . the 3-storey space consists of mass timber supported by glulam post and beam, on top of a reinforced concrete walkout basement. Engineered and built in collaboration with @quantumproperties.ca , Site Lines Architecture, and @seventhdayadventistsda .

We lifted the bending-active Assembly Atlanta timber gridshell into place last week! Likened to a timber trampoline (and a Pringle), the two gridshell layers (4x4 dimensional lumber) were laid out in flat adjacent to the doubly curved glulam ring beam and lifted in a matter of 1.5 hours. It was incredible seeing how light and flexible the grid was - even at an 82ft clearspan. The structural concept is a Chebyshev gridshell created with elastically bent members supporting two layers of plywood - almost acting as a temporary formwork. The two-layer lattice shape was form-found through a series of computational and physical model exercises, including 1:80, 1:50, and 1:10 scale models built using our in-house 3D and laser printers. Working with our engineering team, StructureCraft's carpenters devised in-house glulam presses in order to achieve each of the 6 different doubly curved ring beam segments from singly curved billets, and then hand-planed them into the chamfered shape you see. The structure uses Alaskan Yellow Cedar for durability. We are honoured to be the structural engineer of record, fabricator, and installer for the superstructure, working alongside an incredible team: Client: @assemblyatlanta , @graymedia , Gibson Company Architect: @smithdalia.arch Contractor: Bailey Construction Singly curved glulam: @westernforestproducts Precast concrete plinths: @sanderson.concrete Media: @flor.projects #gridshell #structurecraft #structuralengineering

If you're in London this week, Lucas Epp will speak both at @iabsehq (Annual Lecture 2026) and NXT BLD, urging a reunion of design and construction through the use of technology. @lucasepp will give this year's IABSE Annual Lecture on May 14 at the @istructe_official Headquarters, reviewing our latest work with materiality and structure, including the bending-active Chebyshev timber gridshell for FIFA / Gray Media in Atlanta, the new Gelephu International Airport, and the Barbados National Performing Arts Centre. At NXT BLD, he will give a talk titled "Structural Design at the Speed of Thought": generating structural options takes too much time – yet is critical to understanding both cost, carbon, and systems integration in any building. Lucas's software startup, @branch.3d , unlocks this by enabling realtime analysis and design of structures in all materials, with a deep understanding of structural systems, manufacturing, and carbon. ➡️ IABSE Registration(almost sold out): .uk/event/iabse-annual-lecture-2026-lucas-epp/ ➡️ NXT BLD Tickets: /tickets/ #iabse #structurecraft #structuralengineering #lecture

Join us next week for a tour of the 280ft-clearspan Upper Macungie Township Community Lifestyle Center in Pennsylvania! In collaboration with Shannon Williams of @woodworksusa , Peter Epp of StructureCraft will lead attendees through an up-close look at the design and construction challenges the architect, engineer, and contractor overcame to achieve a timber span of this scale. When: May 8 @ 12:00 pm - 1:30 pm EDT Where: 340 Grange Road, Allentown, PA Register at the link in our bio. @flor.projects #structurecraft #structuraldesign #masstimber

Upper Macungie Township Community Lifestyle Center, currently under construction in Pennsylvania, USA, is a recreational facility designed for large span indoor sports including soccer and basketball. The structure is defined by hybrid timber steel portal frames spanning 85 meters across the main hall. Glulam members form the primary system, combined with steel tension bracing to stabilize the structure and control lateral forces. The long span trusses are prefabricated in three segments to match crane capacity during erection. Construction relies on preassembly and sequential installation, where structural elements are positioned efficiently on site. The project demonstrates how mass timber can achieve clear spans while working with steel for structural performance. © @structurecraft_ ; @uppermactwp ; @hka5architecture 📍 Pennsylvania, USA #ArchitectureLab #MassTimber #HybridStructure #Glulam #StructuralEngineering #SportsArchitecture #Construction

Reimagining mass timber as curved shell elements: 2026 Pavilion at the Mass Timber Conference. Designed in collaboration with our long-time partners, @lakeflato , the pavilion comprises three self-supporting curved DLT panels spanning 30 feet in the weak axis, fabricated flat and bent into shape at the Oregon Convention Center atop shaped DLT walls. When StructureCraft began planning for the @masstimberconference with Lake Flato, we established one rule: Don't just build a box! Push innovation in design and material use. What if curved geometry was simple? The key structural principal was that the panels get their rigidity from curvature, not depth or mass. Timber performing as a shell, not a beam. Shell construction has belonged to concrete and steel for over a century, and this would be a first of its kind worldwide. StructureCraft kicked off R&D in January in our Abbotsford shop, which included a test fit of a scaled-down version of the booth. The door was the most difficult part of the process: a section of curved wall panel that peels away and hinges open on its own dowels. The bendy door stole the show. Visitors pulled it open, felt the flex and spring, and watched solid timber swing like fabric. One highlight was a visit from celebrated Japanese architect Kengo Kuma, who stopped by and was photographed smiling and interacting with the bendable door. The structure will also be featured at the The American Institute of Architects (AIA)'s national Conference on Architecture in San Diego next month. Come see it once again!

Optimization studies: purlin-plywood roof panel layout for Columbia River Maritime Museum. For the Mariners Hall Expansion project with @opsis.architecture , our task was to rationalize the curving roof geometry into something buildable and cost-effective, while maintaining the architectural expression... building light, like a boat. Glulam ribs span up to 60ft across the gallery space, rationalized into three segments: leaning columns on the north, curved in the middle, and cantilevered southern tails. These support purlin-plywood panels, often a budget-friendly alternative to mass timber for these spaces. The challenge was to optimize the layout of these prefabricated pieces, both for shop assembly & install.
