What Gigon/Guyer does

Gigon/Guyer is a privately held Swiss architecture practice founded in 1989 by Annette Gigon and Mike Guyer, headquartered in Zürich. The firm operates in the built-environment sector, offering services across three stated practice areas: infrastructure, rebuilding (renovation/reuse), and urban planning. As a for-profit private firm with 11–50 employees, it sits in the small-practice segment of the Swiss architecture market, where studios typically compete on principal-level design authorship rather than scale.

The firm's positioning is grounded in the reputation of its two named founders, whose identities constitute the brand. No specific products, technology platforms, proprietary tools, or packaged service offerings are documented in the available data; delivery is consistent with a conventional professional-services model in which architects are commissioned on a project basis to produce design, planning, and oversight deliverables. No information is available on pricing models, fee structures, project pipelines, or customer segments, indicating the firm's public commercial footprint is limited to its website (gigon-guyer.ch) and any project portfolio it chooses to disclose.

No information is available on ownership structure beyond the named founders, no parent company or subsidiaries are recorded, no funding rounds have been disclosed (consistent with a self-funded professional services firm), and no M&A, partnership, or leadership-change activity is documented in the input. The available data is sparse overall: most structured data fields are empty, and the only referenced third-party source returned a loading page with no substantive corporate information. The picture that emerges is of a small, founder-led, long-tenured Swiss architecture studio with stable but largely opaque commercial signaling.
