What AW Architektur does
AW Architektur, operating since 2018 as a sole proprietorship under founder Anna Wollenberg and rebranded in 2026 to Wollenberg Architekten BDA, is a Düsseldorf-based boutique architecture and interior design practice specializing in "Bauen im Bestand" (building in existing structures). The firm's core service is full architectural planning delivered across all HOAI phases (LP1–8), spanning feasibility studies, concept development, permit strategy, execution planning, and construction supervision, with a thematic focus on the renovation, adaptive reuse, and heritage-sensitive (Denkmalschutz) transformation of residential, commercial, industrial, and cultural buildings rather than demolition and new construction. Its service portfolio is organized into three lines: Architecture, Interior Architecture (workspace, gastronomy, hotel, exhibition design), and AWA Beratung, a consulting arm offering workplace/New Work advisory, permit and building-law strategy, and project management.
The firm operates as a project-based professional services business charging fees per the German HOAI statutory ordinance, calculated as a percentage of construction costs, with custom quotes per engagement and multi-year contract cadences. Go-to-market is consultative and direct ("Beratung vor Planung"), with no intermediaries or marketplaces; clients engage via the firm's website, referrals, and earned media exposure. Customer segments span enterprise (e.g., thyssenkrupp Steel Europe, Bungartz, Metropol Kino Düsseldorf), private homeowners and SMBs (residential renovations, listed-building conversions), and municipal/investor clients pursuing commercial-to-residential repurposing. The firm is bootstrapped and founder-owned with no external investment, holds professional liability insurance of €1M (property/financial) and €3M (personal injury), and operates exclusively in the Düsseldorf / North Rhine-Westphalia region with project work extending to Duisburg, Leverkusen-Hitdorf, Krefeld, and Bochum. Anna Wollenberg, the founder and Geschäftsführerin, was the youngest member admitted to the Bund Deutscher Architekten (BDA) at induction in 2018 and was elected to its board in 2021.
