Treberspurg & Partner Architekten

What Treberspurg & Partner Architekten does

Treberspurg & Partner Architekten ZT GmbH is a Vienna-based architecture firm founded in 1996 by Martin Treberspurg as an Austrian Ziviltechniker GmbH (civil engineering company) headquartered at Penzingerstraße 58 in Vienna's 14th district. The firm specializes in sustainable, resource-oriented architecture with emphasis on passive house standards, solar architecture, and energy-efficient construction methods. It operates with 11–50 employees and has completed over 70 projects since inception spanning residential, educational, civic, and cultural categories across Vienna, Lower Austria, Upper Austria, Styria, and Burgenland. Notable documented outcomes include heating energy reductions of approximately 90% through passive house retrofits and operational energy consumption as low as 9 kWh/m²a.

The firm's technical differentiators include two proprietary systems developed through a long-standing research partnership with BOKU Wien: the MAFA (Multi-Active Facade) — a prefabricated, ventilated glass facade with integrated photovoltaics and heat recovery — and the PV-Dachgarten (PV Roof Garden), a semi-transparent PV pergola enabling triple-use of roof space. Service offerings encompass new construction, renovation, heritage restoration, and specialized sustainable-building consulting. The firm has won the 1999 UIA Sir-Robert-Matthew Prize (world architecture) and the 1993 Upper Austrian Landeskulturpreis für Architektur. Leadership transitioned in 2020 when Christoph Treberspurg assumed the Managing Director role; senior partners include Bernhard Kollmann and Doris Österreicher.

The business model is professional-services based, generating revenue from architectural planning, general contractor supervision, and project management fees negotiated per project. Client acquisition is event-driven: the firm primarily wins work through architectural competitions (Wettbewerbe) at municipal, regional, and national levels, supplemented by direct commissions and repeat engagements with public institutions and housing cooperatives. Key clients include the City of Vienna, Wiener Wohnen (municipal housing), BOKU Wien (university), OMV, Volkshilfe, and housing cooperatives including Neues Leben and Wien-Süd. The firm is privately held with no disclosed external investors or parent company.
