Bauart Architekten

What Bauart Architekten does

Bauart Architekten is a sole proprietorship architecture firm operating under Dipl.-Ing. Architekt Friedhelm Birth from a single office in Hannover, Lower Saxony, Germany. The firm provides comprehensive architectural services across the full nine Leistungsphasen defined by the German HOAI fee ordinance, deliverable either as complete project packages or as individual phase services (Teilleistung). Its core technology stack is human architectural expertise augmented by domain-specialized credentials: Passive House planner certification from Passivhausinstitut Darmstadt, KfW Effizienzhaus 70 accreditation for energy-efficient renovation, proKlima Hannover quality assurance, SiGeKo safety/health coordination, and heritage-conservation (denkmalgerechte) restoration competency.

The service portfolio covers new construction, conversion, extension, renovation and modernization for residential, commercial, administrative, and industrial buildings, alongside adjacent offerings in energy consulting, building defect and damage analysis, expert appraisal reports, project development for Baugruppen (collective housing groups), and environmental/health protection planning. Distribution is exclusively direct: clients engage through consultation meetings with no intermediaries, marketing channels, or digital sales infrastructure beyond a basic informational website. Pricing is governed by the statutory HOAI fee structure rather than market-based negotiation, and the firm holds no patents, trademarks, public funding, or external investors.

Customer segments are horizontally diversified across private residential owners, small commercial clients, renovation/heritage property owners, and Baugruppen collectives, all served primarily within the Hannover/Lower Saxony region. The firm is registered with Architektenkammer Niedersachsen (#11.664), operates under VAT-ID DE317178169, and is GDPR-compliant. There are no subsidiaries, no parent company, no public listing, and no disclosed financial figures.
