Jonny Sin has launched Sin&Co, a new boutique studio headquartered in London.

Sin&Co specialises in premium hospitality and lifestyle senior living environments, with studios in London and Auckland and strategic partnerships in Spain.

The studio designs elegant, functional spaces that respond to their context, often drawing on local communities, craftspeople and culture, while balancing creativity with operational performance.

Founded in 2025, Sin&Co brings together deep sector expertise and a global perspective. The studio offers full architectural services, strategic consultancy and client-side representation for developers, operators and brands seeking an experience led, performance driven approach.

Sin brings over 20 years of experience delivering high-profile developments across the UK, Europe, the Middle East, Australasia and East Asia. Over the past 14 years, he has worked exclusively in the hospitality sector, serving as a Board Director at ReardonSmith Architects where he led major projects for clients including The Dorchester Collection, Grosvenor Estates and The Reuben Brothers, as well as collaborating with global brands such as Rosewood Hotels & Resorts, Mandarin Oriental and Wanda Vista.

Sin&Co is supported by strategic collaborations with trusted international partners, including BAT – Bilbao Architecture Team – one of Spain’s leading multidisciplinary architecture firms, with over 40 professionals across architecture, interior design and construction. BAT serves as the strategic and technical partner for the UK studio, providing Sin&Co with a powerful project delivery platform.

As part of this collaboration, Peru Cañada and Xabier Arranz, partners at BAT, work closely with Sin&Co, strengthening the studio’s reach across the UK and international markets.

Originally from New Zealand, Sin draws on this personal and professional heritage to inform the studio’s global outlook and values. Sin&Co blends international insight with local expertise to deliver projects that are both refined and responsive.

“Sin&Co is a studio built on precision, clarity and care,” says Sin. “We are intentionally boutique, strengthened by strategic partnerships. Our value lies in rigorous design thinking, close collaboration and the ability to navigate complexity while delivering work that performs creatively, commercially and operationally.”
