Frequently Asked Questions

Essential answers regarding steel construction, energy targets and project delivery.

Each country has specific energy performance regulations (e.g. GEG in Germany, RE2020 in France, Part L in Ireland). We design our steel envelope to comply with your local code requirements.

Statutory permits, local planning submissions, and national structural certification must be signed by a registered local architect or engineer in your jurisdiction.

Steel frame kits and building materials are packed into shipping containers or trucks. Transport and customs clearance terms (Incoterms like DAP or CIF) are detailed in each quote.

Yes. We offer experienced erection supervisors who oversee local assembly teams to ensure structural alignment and airtight envelope execution.

Yes. For Scandinavian and Alpine regions, wall insulation thicknesses can be increased up to 300-400mm with U-values down to 0.10 W/m²K.
