What SH/OT Architecture does

SH/OT Architecture is a Paris-based boutique interior architecture firm co-founded by Stéphanie Otto and Aurane de Saint Hilaire. The firm delivers full-service interior architecture and renovation design, encompassing spatial planning, material selection, custom furniture integration, and project execution for affluent private residential clients and select commercial customers. Its core offering centers on the complete renovation of family apartments and lofts in Paris, with project sizes documented between 70m² and 300m² across the VIII, XVI, and XVII arrondissements and Neuilly-sur-Seine. The firm has also extended into commercial space design, exemplified by the DL La Suite hair salon project.

The firm's value proposition rests on the complementary creative perspectives of its two co-founders, who blend French savoir-faire with culturally diverse materials to produce individualized project outcomes. A standing partnership with Santillane Design extends delivery capacity on certain residential and commercial engagements. The firm maintains an active website portfolio as its primary marketing channel and relies on direct client engagement rather than intermediary distribution.

Commercially, SH/OT operates a project-based professional services revenue model. Each engagement is a one-time contract with bespoke pricing quoted per project; no standardized pricing, retainers, or subscription structures are disclosed. Customer acquisition is driven by the visible portfolio, word-of-mouth referrals, and direct inquiries via the firm's website. The firm is privately held by its two co-founders with no external institutional investment, no parent company, and no disclosed headcount, revenue, or funding. Geographic activity is concentrated in the Île-de-France region, with no evidence of broader international expansion.
