India Sotheby’s International Realty and Interiors With Art Ltd have formed a strategic joint venture to raise the benchmark for ultra-luxury living in India. The partnership will offer bespoke end-to-end design and architecture consultancy for ultra high net worth individuals (UHNIs) and high net worth individuals (HNIs) across the country’s expanding luxury residential market. India Sotheby’s International Realty (India SIR) will combine its leadership in the Indian luxury real estate sector with Interiors With Art Ltd (IWA), a UK-based design practice. IWA brings over 24 years of experience in the United Kingdom and a reputation for delivering world-class interiors for global billionaires and royal families across Europe, the Middle East and India. The studio’s leadership includes creative director Shailja Vohora, who has more than 35 years of international design experience, and Sanjay Sharma, who provides strategic and operational leadership informed by global commercial experience. The firm also expects a next generation direction under Shreya Vohora, who focuses on wellbeing-led design, technology integration and digital strategy. Amit Goyal, managing director of India SIR, said the collaboration is intended to bring a new dimension of luxury to clients by blending international aesthetics with local craftsmanship and market insight. IWA leadership described the expansion into India as an opportunity to curate residences that reflect clients’ lifestyles, emphasise artisanal traditions and support long-term wellbeing. Sanjay Sharma noted the firm’s emphasis on discretion, craftsmanship and operational rigour when delivering high-value projects. The partnership comes as the Indian luxury housing segment experiences strong growth and buyers seek global standards of sophistication, technology and personalisation. India SIR is part of the Sotheby’s International Realty network present in 84 countries and territories with 1,100 offices and 26,100 sales associates, achieving a transaction volume of United States dollar (USD) 157 bn in 2024.
