The Architect & Interior Expo 2026

The Architect & Interior Expo 2026 (BIG3 Architect & Interior Expo) is one of India's most established and influential design and specification platforms, returning for its landmark 10th edition at the Chennai Trade Centre from 25 to 28 June 2026. Organised by BIG3 Exhibitions, the event has built a decade-long reputation as a focused, high-quality marketplace that connects architects, interior designers, developers, builders, and premium brands shaping the future of the built environment in South India and beyond.

The expo is purpose-built as a specification platform, meaning it is designed to bring decision-makers and influencers in the design and construction community face to face with the manufacturers and brands whose products they specify and recommend. This targeted focus distinguishes the event from generic trade fairs and ensures that exhibitors meet a highly relevant audience of professionals with genuine purchasing and specification power.

Across four days, the exhibition showcases an extensive range of products and solutions spanning the entire interior and architectural spectrum. Visitors can explore surfaces and finishes, flooring, tiles and stone, modular kitchens and wardrobes, lighting and electrical solutions, sanitaryware and bathroom fittings, doors and windows, facades and cladding, furniture, decor, smart-home technologies, and a wealth of building materials and finishing products. The breadth of categories makes it a comprehensive sourcing destination for anyone involved in designing, building, or furnishing residential, commercial, and hospitality spaces.

A defining feature of The Architect & Interior Expo is its emphasis on design excellence and innovation. The show floor typically features curated displays, brand experiences, and live product demonstrations that allow visitors to engage directly with the latest materials, technologies, and aesthetic trends. This hands-on experience helps designers and specifiers stay ahead of evolving client expectations and discover solutions that combine functionality, sustainability, and visual appeal.

The event also serves as a vibrant networking and knowledge-sharing hub. Through seminars, panel discussions, and presentations, leading architects, designers, and industry experts share insights on emerging themes such as sustainable design, biophilic and wellness-focused interiors, smart and connected spaces, and the integration of technology into modern architecture. These sessions provide valuable professional development and inspiration, helping attendees translate trends into practical project applications.

Chennai's position as a major hub for architecture, real estate, and design in South India makes it an ideal host city. The region's dynamic construction sector and growing appetite for premium, design-led interiors create strong demand for the products and partnerships on offer, drawing visitors from across Tamil Nadu and neighbouring states as well as national and international exhibitors.
