Building virtual architecture for more than 10 years. Creating extraordinarily atmospheric and detailed imagery of yet-to-be-built architecture is our core competence, alongside digital set design, 3D animation and post production. rendertaxi was founded by the architects Alexander Pfeiffer and Felix Volland based in Germany, both with over a decade experience in architecture and visualization. Since 2013 we have a second base in Barcelona managed by Roberto Valls. He worked for several years in the office in Aachen before becoming office leader and partner in Barcelona.
