Structural design, independent verification, and specialist work in temporary, tensile and acoustic structures — delivered in four languages, from Porto to wherever your project stands.
Clear analysis, traceable calculations, and a recommendation you can act on — engineering as a service, not a black box.
One point of contact for design, checking and specialist structures — from permanent buildings to structures that stand for a weekend.
Steel, aluminium and timber structures designed to Eurocodes — from concept to fabrication drawings.
Third-party checking of structural designs — calculations reviewed, assumptions challenged, sign-off you can rely on.
Stages, grandstands, towers and tents — engineered for fast assembly and certified safety.
Form-finding, patterning and analysis of fabric and cable structures.
Acoustic design and assessment for venues, events and building envelopes.
Detailed finite-element modelling for complex geometries, dynamics and non-standard structures.
Engineering oversight during construction — inspections, method statements and on-site problem-solving.
Qualified engineers to reinforce your team — by the project or seconded on demand.
From permanent buildings to structures that stand for a weekend — we work where performance, speed or geometry make engineering matter.
From first sketch to signed calculation, every structure is checked against the codes that keep it standing.
Computation changes the result in two concrete ways — both under full human verification.
We test far more design options than a deadline usually allows — driving down mass, material and cost, with every option checked against the Eurocodes.
Automation handles the repetitive calculation work, so you get options, iterations and answers faster — without cutting corners.
Every result is verified by a human engineer and signed. See the Sellium Protocol.
We turn the calculations that eat our time into fast, Eurocode-based tools — the same computational edge, packaged. First releases coming soon.

Four commitments on every project — whatever the size.
We use computation and automation to move fast — but no tool output reaches you without an engineer's review.
Every number in our deliverables can be traced to a code clause, a test, or a stated assumption.
Independent internal checking before anything is issued — the same gate for a stage roof or a building.
Responsibility is not delegated to software. An engineer signs, and stands behind, every deliverable.
Sellium is an engineering practice led by a structural engineer with international project experience across Europe, the Middle East and Asia — from event structures for global brands to long-span and specialist work.
We work directly with architects, contractors and manufacturers — clear communication, fast turnaround, and calculations you can take to any checker, authority or client.
A small research line explores deployable structures for extreme environments — the same lightweight, fast-assembly engineering that drives our event work, taken further.
A lead engineer who signs and stands behind every deliverable — backed by a network of specialists engaged per project.
International project experience across four continents — the USA, Brazil, Peru, India, Saudi Arabia, Australia, Africa and Europe — from event structures for global brands to long-span and specialist work.
A short brief is enough to start — drawings, loads, deadline, and what you need from us.
