All3 vs Strong by Form
Two offsite companies that pair computational design with automated timber fabrication, at different scales. All3 is a vertically integrated housing builder: its Real Time Architecture platform uses AI agents to generate and score multi-storey timber building designs, robotic factories make the components, and its Mantis robot assembles them on site. Strong by Form makes Woodflow timber components, a structural floor slab system (Woodflow-core, still in validation) and 3D cladding (Woodflow-skin, market-ready), by steering wood fibers along stress lines with computational design and additive manufacturing, and sells components rather than whole buildings.

| AI role (our label) | AI-first | Not AI-first |
| What it does | Vertically integrated construction technology company for multi-storey timber housing that uses AI agents to generate and score building designs. Its Real Time Architecture (RTA) design platform uses AI agents to generate massing, layouts, and circulation options, scores them on usable area, cost, daylight, and code compliance (it cites DIN standards), then builds a component-level structural model using genetic algorithms and parametric optimisation, with automatic fire, acoustic, and thermal checks. All3 says a coordinated model takes about nine hours versus months conventionally (vendor claim). The model feeds bills of materials and robotic production programmes; components are made in robotic factories the vendor says run at 90% automation, and assembled on site by Mantis, its autonomous construction robot. Pilot factory in Belgrade. Architects can import DWG and export DWG or BIM; All3 says some software features can be used on their own but the system is designed to run as a whole. Re-checked Oct 19, 2026: an Oct 7, 2026 post unveils the second-generation Mantis, a 135 kg electric four-legged robot that All3 says carries up to 100 kg while walking, climbs stairs up to 35° with its 45 kg arm attached, narrows to pass a 900 mm doorway, applies about 900 N of thrust to drive 80-120 mm structural screws, and runs on two hot-swappable battery packs; it says Mantis found and drove screws into eight of eight pilot holes in repeated runs and is designed against a catalogue of 68 construction operations. All3 says machine learning is used in walking, planning and perception, kept separate from a deterministic control loop for force and emergency stops. Cost, time and CO2 percentages on the homepage are vendor claims and are not repeated here. Re-checked Oct 21, 2026: homepage unchanged in substance (AI-powered design platform, robotic factories, Mantis on-site assembly); its news list adds an Oct 8, 2026 post from its mobile robotics team and an Oct 14, 2026 podcast episode. The homepage cost, time and CO2 percentages remain vendor claims not used here. Re-read Oct 22, 2026 for a compare: homepage, Real Time Architecture page and FAQ unchanged in substance (AI agents generate massing, layouts and circulation and score options on developer metrics, end-user quality and compliance; component-level structural model by genetic algorithms and parametric optimisation; automatic fire, acoustic and thermal checks; output to bills of materials and robotic production programmes; DWG import and DWG or BIM export; architects can drive the system with prompts). The FAQ says All3 delivers end to end from design to approved buildings (fit-out optional), focuses on multi-storey residential and mixed-use on constrained urban sites, runs a pilot factory in Belgrade, and can set up a dedicated factory in a large client's market, typically within six months; it says buildings will meet DGNB Platinum and projects will achieve BREEAM Outstanding and LEED Platinum (stated intent, not verified). Timber supply, cost, time and CO2 figures remain vendor claims not used here. | Develops Woodflow, which aligns wood fibers with stress lines to make complex, lightweight timber components by additive manufacturing. Woodflow combines computational design, proprietary fiber-steering software, and an industrial additive manufacturing process. Woodflow-core structural slabs are claimed to be carbon-negative, 90% lighter than concrete, and cost-competitive at scale (vendor claims); the FAQ says Woodflow-core is at TRL 6, in advanced prototyping and validation. Woodflow-skin 3D cladding is described as market-ready. The vendor also lists integrated design software for simulating performance and optimizing material distribution, and applications in vehicles and mass transit. The site does not describe AI. Re-checked Oct 19, 2026: a Sept 10, 2026 post says it closed a US$6.6 million first tranche of a Series A to install a pilot plant in Spain (Basque Country or Castilla y León under evaluation, target late 2027) to certify its structural floor panel and run first commercial projects with European builders; it currently runs a plant in Santiago, Chile, with four robots and laser cutting machines. The homepage also names BMW, Talgo and NS as mobility partners. Still no AI described, so the Not AI-first tag stays. Re-checked Oct 20, 2026: a Sept 25, 2026 news post says it showed Woodflow train ceiling panels at InnoTrans 2026 in Berlin on the Europe for Rail stand. The homepage carries two weight comparisons on different baselines: one paragraph says its carbon-negative slabs and components cut emissions by up to 75% and weigh 59% less than CLT, while the construction line still says Woodflow-core slabs are 90% lighter than concrete (vendor claims, not verified; neither figure is sourced on the page). Still no AI described. Re-checked Oct 21, 2026: the homepage no longer shows the paragraph with the 75% emissions and 59%-lighter-than-CLT figures; it still says Woodflow-core slabs are 90% lighter than concrete and cost-competitive at scale, adds a mobility line (7% lighter than aluminum, 90% less CO2) and adds maritime to the FAQ's industry list. The Woodflow-core page describes a prefabricated structural system for long spans and high-rise buildings with 10 m+ spans; its headline says 90% lighter than reinforced concrete slabs while its comparison table says 92% lighter (flagged; vendor claims, not verified). Still no AI described. Re-read Oct 22, 2026 for a compare: the homepage again shows the paragraph with the up-to-75% emissions and 59%-lighter-than-CLT figures alongside the 90%-lighter-than-concrete line (vendor claims, not verified), and still carries lorem ipsum placeholder text in one section. Its news list adds a Woodflow-skin installation in the departures hall of Quito's international airport in Ecuadorian balsa wood with 3A Composites and Corporación Quiport. The Woodflow-core page describes a strand-based formulation that can use low-grade wood and spans of more than 10 m for commercial and office use; the FAQ still puts Woodflow-core at TRL 6 and Woodflow-skin as market-ready. Still no AI described. |

Where the vendor descriptions differ
- What you buy: All3 describes an end-to-end service from initial design to approved, ready-to-use buildings, covering design, structural engineering, robotic off-site fabrication and on-site assembly, with fit-out optional; it focuses on multi-storey residential and mixed-use buildings on constrained urban sites, and says some software features can be used on their own but the system is designed to run as a whole. Strong by Form sells components: Woodflow-core, a prefabricated structural slab system for long spans (more than 10 m for commercial and office use) and high-rise buildings, and Woodflow-skin cladding, distributed in the US through The Wood Veneer Hub; it also makes parts for rail and other vehicles.
- Design software: All3's Real Time Architecture takes zoning plans, building codes, height limits, access and context, has AI agents generate massing, layouts and circulation, scores options on developer metrics, end-user quality and compliance, then builds a component-level structural model with genetic algorithms and parametric optimisation and checks fire, acoustic and thermal performance automatically; output goes straight to bills of materials and robotic production programmes, and architects can import DWG, export DWG or BIM and drive the system with prompts. Strong by Form describes proprietary fiber-steering software and computational tools that generate double-curved forms, in a design-to-fabrication workflow where architects and engineers simulate performance and optimize material distribution.
- AI: All3 is tagged AI-first (AI agents in design; it has said machine learning runs Mantis's walking, planning and perception, kept separate from a deterministic control loop). Strong by Form is tagged Not AI-first: its pages describe computational design and software but not AI.
- Material and production: All3 builds in mass timber (its FAQ cites CLT fire testing to EN1995-1-2 and ASTM E119), makes components in robotic factories with a pilot factory in Belgrade, and says it can set up a dedicated factory in a large client's market, typically within six months. Strong by Form uses a strand-based formulation that can take low-grade wood, chips or veneers in an industrial additive manufacturing process; it runs a plant in Santiago, Chile, and said in Sept 2026 that a US$6.6 million first Series A tranche will fund a pilot plant in Spain (target late 2027) to certify its structural floor panel.
- Readiness (vendor statements): Strong by Form's FAQ puts Woodflow-core at TRL 6 (advanced prototyping and validation) and Woodflow-skin as market-ready, with a balsa installation in Quito airport's departures hall. All3 unveiled its second-generation Mantis in Oct 2026, and its FAQ says its buildings will meet DGNB Platinum and projects will achieve BREEAM Outstanding and LEED Platinum (stated intent).
- Pricing (checked Oct 22, 2026): neither publishes prices. All3's /pricing returns not found and its calls to action are Cost your project and Request a consultation. Strong by Form's /pricing returns not found and Contact us is the call to action.
- Not used here: All3's cost, time, CO2, automation and nine-hours-versus-nine-months figures and timber supply numbers, and Strong by Form's weight, emissions, cost-competitiveness and margin figures (vendor claims). Neither tool has been tested by Means & Methods Lab.
