Kast Kaeppeli Architekten

What Kast Kaeppeli Architekten does

Kast Kaeppeli Architekten GmbH is a Swiss architecture firm founded in 2008 by Adrian Kast and Thomas Kaeppeli, operating from two offices in Bern (Gerberngasse 23) and Basel (Stapfelberg 7). The firm delivers comprehensive architectural services spanning competition design, planning, project management, and construction supervision, with documented work in educational buildings (Volksschule Kleefeld, Enge, Spitalacker, Doppelkindergarten Sissach), cultural institutions (Bernisches Historisches Museum extension), residential projects (Jurastrasse, Zähringerstrasse), and recreational facilities (Ka-We-De bath renovation). Technical specialization includes sustainable construction methods, with VS Kleefeld cited as one of Switzerland's pioneer projects for CO2-enriched concrete and timber-construction expertise recognized through Prix Lignum.

The firm's business model is professional services revenue through architecture fees calculated as a percentage of construction cost or fixed project rates. Go-to-market is exclusively sales-led and competition-driven: projects are acquired through Swiss public architecture competitions, juried selection procedures, and selective tender processes, with the firm participating in and frequently placing (1st, 2nd, 3rd ranks) in competitions organized by municipalities, cantons, and federal agencies. Customer concentration skews heavily toward Swiss public-sector clients, including Hochbau Stadt Bern, Immobilien Stadt Bern, SBB Immobilien, Bundesamt für Bauten und Logistik (BBL), Burgergemeinde Bern, and Bernisches Historisches Museum; private developers and housing cooperatives form a secondary segment. Marketing is conducted through competition participation, recurring features in Swiss architectural journals (Hochparterre, Tec21, werk, bauen + wohnen), Open House Bern events, and an Instagram channel launched in February 2024.

The firm has accumulated multiple industry recognitions, including best architects Gold (2021, Jurastrasse 58), best architects 24 (VS Kleefeld), best architects 26 (Parkcafé Kleine Schanze and Volksschule Enge, 2025), SUPERHINK 2025, and Landscape of the Year 2024. The legal entity is a privately held GmbH with no external investors, parent company, or disclosed funding events; it operates as an independent partnership between the two named founders.
