UNISON Design

What UNISON Design does

UNISON Design is a Hamburg-based, sole-proprietor interior architecture and design studio offering full-service interior design for residential, commercial, and public spaces. Founded in 2013 and reorganized in 2024 under Managing Director Alexander Klein following a merger with AYVEE, the firm operates with 1-10 employees and a project-based professional services model, charging quote-based fees for concept development, spatial design, furniture and lighting design, contractor coordination, construction supervision, and handover.

Its core offerings span five project categories — Gastronomie (restaurants/bistros), Büro (offices), Wohnraum (residential), Retail, and Nachhaltigkeit (sustainability-focused projects) — supported by service modules in custom furniture (Möbeldesign), lighting design (Beleuchtung), and Healthy Design Coaching grounded in Cradle-to-Cradle methodology. The studio positions itself as independent (no supplier binding) and coordinates directly with trade partners such as Tischlerei Trede for joinery.

The firm's go-to-market is sales-led, relying on direct client engagement, referrals, and design partnerships with architecture and design firms, most notably BFGF GmbH & Co.KG (long-standing), Being Born, and lnset Group (Sydney). The client roster is horizontally diversified across hospitality, beauty retail, corporate office, law firms, and high-end residential customers in Hamburg and selective international projects (Sydney, Munich, Fayence). Marketing is primarily organic via the firm website, Instagram, and LinkedIn showcasing a project portfolio that includes heritage brands (Shiseido, L'Occitane, Benefit Cosmetics, Elizabeth Arden) and Hamburg-based SMEs. The firm has no disclosed external funding and operates as an independent sole proprietorship.
