What Dekleva Gregoric Architects does

Dekleva Gregoric Architects is a Slovenian architectural studio founded in 2003 and based in Ljubljana, operating as a privately held limited liability company (Dekleva Gregorič arhitekti, projektiranje d.o.o.) under founders Aljoša Dekleva and Tina Gregorič. The studio delivers architectural design services across four practice areas — Houses, Housing, Public buildings, and Exhibitions/Research — for private residential clients, public and institutional clients (municipalities, universities, healthcare operators, national housing trusts), and selected international private clients. It has completed or is progressing on over 70 projects ranging from 43 m2 micro-houses to 200,000 m2 urban master plans, with completed work in Slovenia, the USA, Portugal, Austria, Germany, and Croatia.

The studio's technical foundation rests on systematic and parametric design approaches, including the patented Dowel-Laminated Timber (DLT) construction system (developed with IQwood), modular housing catalogues (HOUSE SYSTEM+ for 2023 Slovenia flood relief), the open-source Xh System House (released 28 October 2016), and the prefabricated Monohouse system (14-25 m2). These products sit alongside core architectural services (concept design, competition entries, master planning, sustainable construction consulting) and are supported by research and exhibition work. Notable commissions include Housing Novo Brdo (46,600 m2, 500 homes), the Infectious Diseases Clinic for UKC Ljubljana (25,500 m2), University Campus Livade (51,650 m2), the Emergency Operations Centre Ljubljana (15,000 m2), and the Slovenian Pavilion for Expo Osaka 2025.

The business model is professional services-based, with fees negotiated per project and not publicly disclosed. The studio's go-to-market is reputation-driven, combining participation in open and invited architectural competitions (the primary acquisition channel for large public and institutional projects) with direct commissions from private clients. Marketing is conducted almost entirely through earned media in leading international architecture publications (Wallpaper*, ArchDaily, Dezeen, Designboom, Architectural Review) and through competition wins. The firm has received multiple Mies van der Rohe Award nominations (2013, 2015, 2023), several Golden Pencil awards, the Plečnik Medal, and Architecture Masterprize 2025 recognition. Revenue is not publicly disclosed, and there are no external investors, funding rounds, or subsidiary entities.

Revenue model

1. Architectural Design Services: Revenue is generated through fees for architectural design services on commissioned projects, open competitions, and invited competitions. Projects range from small residential commissions to large-scale public and housing developments. Competition wins (open and invited) serve as primary acquisition channels for larger public and institutional projects.
2. Open-Source Design Licensing: The Xh System House is released as open-source architecture, freely available to anyone to build and customise. This represents a non-traditional revenue approach where the design is freely distributed rather than commercially licensed.
