SPEC Toolbox has replaced CLT Toolbox. CLT Toolbox just made an exciting announcement about its renaming. It is a move that reflects the current construction tech landscape’s growing diversification. This move represents the platform’s growth from a specialised mass timber tool to a complete, multi-material design infrastructure intended to close the gap between structural engineers and product makers. It is much more than just a name change.
Coinciding with this rebrand is a significant operational milestone: the major expansion of its free offering in Europe. For the first time, engineers across the continent can unlock the platform’s entire suite of calculators at no cost when designing with products from SPEC Toolbox’s global network of supply chain partners.
One of the primary friction points in modern construction is the “specification bottleneck.” Engineers often spend hundreds of non-billable hours creating custom, unverified spreadsheets to interpret technical data buried in manufacturer PDFs.
SPEC Toolbox addresses this by providing transparent, Eurocode-compliant calculations. Unlike “black box” software that hides the logic behind results, SPEC Toolbox provides full visibility into formulas and intermediate steps.
While the company’s roots are firmly planted in Cross-Laminated Timber (CLT), the new brand reflects a platform that has grown to encompass eight distinct product categories, including:
The driving philosophy behind the rebrand is to make cutting-edge building materials as easy to specify as traditional steel or concrete.
“Our mission is simple: to make innovation easy to specify,” says Adam Jones, CEO of SPEC Toolbox. “Product manufacturers drive industry innovation, and passionate engineers are seeking solutions that challenge the norm. By providing free access to our tools for our partners, we are putting incredible manufacturer solutions directly into the hands of engineers.”
Jones, who previously served as a Technical Manager at XLam and a specifier at WSP, understands the pain points of both sides of the supply chain. This “by engineers, for engineers” approach has already attracted over 5,000 global users and established partnerships with 30 major industrial suppliers.
The European construction market is currently facing a dual challenge: a shortage of specialised timber engineers and an urgent need to decarbonise the built environment. SPEC Toolbox is positioning itself as the “common infrastructure” to solve both.
By removing the financial and technical barriers to high-performance material specification, SPEC Toolbox is enabling engineering firms—from boutique practices to global consultancies—to scale their capacity for sustainable design.
Headquartered in Melbourne but operating across five continents—including key technical hubs in Addis Ababa and Semarang—SPEC Toolbox brings a unique perspective to global code compliance. The team’s diversity ensures that the software is not only technically robust but also adaptable to different regional regulations, including the latest drafts of Eurocode 5.
As the platform moves into 2026, the roadmap includes further expansion into North American markets (USA and Canada) and the continued integration of AI-driven optimisation tools.
The transition from CLT Toolbox to SPEC Toolbox signals a broader shift in the construction industry: a move toward open, transparent, and collaborative design environments. By aligning the needs of the manufacturer with the precision of the engineer, SPEC Toolbox is ensuring that the “materials of the future” are no longer the hardest to build.
