BT45 — with the self-description "German Kitchen Tailors" — is a luxury kitchen brand developed by BauTeam, a German lifestyle business group headquartered in Frankfurt am Main. BauTeam operates as a brand portfolio company managing different product segments under independent labels: BauBasic, BauLux, BauCloset, BLV and BT45. The company traces its history to 1921. All BT45 components are manufactured in Germany and fully assembled in Germany — using laser-scanning technology for precise quality assurance. Supplies are sourced exclusively from European suppliers to the strictest quality criteria. Lead designer is Natasha Shtapauk, who shapes the brand's aesthetic vision: reference to the design principles of modernism — "ornament is crime" and "form follows function" — combined with the desire to make individuality tangible.
