What HNP architects does

HNP architects ZT GmbH is a Vienna-headquartered, privately held architecture and engineering firm (ZT GmbH) founded in 1973 by Heinz Neumann. The firm operates as an integrated architectural practice offering architectural design, general planning (Generalplaner), and engineering services across commercial office, mixed-use, residential, hotel, heritage-conversion, and urban-quarter typologies. Its portfolio includes landmark Vienna projects such as the UNIQA Tower, Euro Plaza (c. 170,000 m², six phases, ÖGNI Platinum), Ares Tower, the BahnhofCity Wien West, the Park Hyatt Vienna (heritage-listed bank conversion, BREEAM), and Office Park 4 at Vienna Airport (c. 28,000 m², ÖGNI Platinum, ÖGNI Kristall Award). The firm employs roughly 60 staff across approximately 20 active projects and operates under a three-partner governance structure (Heinz Neumann, Florian Rode, Oliver Oszwald).

The technical foundation is a proprietary Building Information Modeling (BIM) standard developed in-house, supported by dedicated BIM moderators and small-group training. This BIM-enabled methodology underpins the firm's general planning role across multi-disciplinary teams and contributes to its repeated delivery of sustainability certifications (ÖGNI Platinum for Office Park 4 and Euro Plaza, DGNB Platinum pre-cert for QBC 1+2, ÖGNI Gold for Square Two, BREEAM for Park Hyatt Vienna). Recent and ongoing commissions include QBC 1+2 (~44,000 m², DGNB Platinum) and QBC 5 hotel (577 rooms) for UBM Development and S Immo AG, the Mandarin Oriental Vienna heritage revitalization for the Brisen Group, the TwentyOne Central Hub, Am Seebogen in Seestadt Aspern for ARE, and two buildings within the VILLAGE IM DRITTEN (~1,900 residential units, completion 2026).

The business model is professional services: project-based fees negotiated per commission, acquired via architectural competitions (e.g., 2017 Office Park 4, 2003 BahnhofCity Wien West), direct commissions from real estate developers and property companies, and long-standing repeat-client relationships with enterprises such as Flughafen Wien AG, UBM Development, S Immo AG, ARE Austrian Real Estate Development, CKV Gruppe, and STRABAG. Customer segments span real estate developers and property companies (primary), residential developers and housing associations, hotel operators and hospitality investors, and urban development bodies and municipalities. Geographic focus is domestic (Vienna and Austria), with limited international exposure through the Swiss-based Brisen Group hotel commission. Distribution is direct, with no resellers or partner channels; marketing is predominantly earned-media via press releases, the LinkedIn company page, and ÖGNI industry association involvement.
