Mat Barnes, founder of the London-based practice CAN, has emerged as a distinctive voice in contemporary British architecture, advocating for designs that embrace individuality and eccentricity over prevailing trends of minimalism and restrained aesthetics. His approach challenges the conventional wisdom of domestic architecture, emphasizing a joyful, “weird” character that reflects the quirks and personalities of the people who inhabit the spaces.

Barnes first gained wide recognition with his project Mountain View, a comprehensive renovation of a neglected Edwardian terrace in south London. The house, named after its location, features bold design choices such as an intersecting plywood box ceiling and a rooftop gable inspired by Disneyland’s Matterhorn. Rather than pursuing the understated Scandinavian or Japandi styles popular over the past decade, Barnes embraced maximalism, producing a home that critics noted seemed to embody the joy and playfulness often missing from architecture. Mountain View was longlisted for House of the Year, attracting attention from television presenter Kevin McCloud and praise from architecture commentators.

Barnes traces his architectural ambitions back to an unconventional path. Raised in Cardiff to a nurse and a haematologist, he initially resisted vocational expectations and a conventional career route. After an unfulfilling stint shadowing a veterinary clinic and a foundation course in art and design, Barnes combined an interest in creative disciplines with a practical compromise in architecture. His architectural education began with initial setbacks—failing to gain entry to Nottingham University—but eventually led to study in London, where he gained hands-on experience at Paul Archer Design. There, he learned the technical realities of building construction while grappling with the limitations of client-driven projects steeped in minimalist aesthetics.

Dissatisfied with the elitism embedded in architectural commissioning and the homogeneity of prevailing styles, Barnes sought alternative avenues to express his vision. Collaborating with artists, sculptors, and set designers on competitions and small projects, he gradually formed CAN in 2016 alongside partner Eddie Blake. Their early work included a sensitive extension for a Grade II-listed townhouse in Highbury and experimental furniture pieces like a Concrete Canvas bench in Silvertown.

Barnes describes CAN’s philosophy as rooted in collaboration and interdisciplinarity, rejecting sterile uniformity in favor of designs infused with personality and humor. He places particular emphasis on accommodating the “peculiarities” of occupants and making architecture accessible and emotionally engaging to the general public. Barnes laments the structural barriers young and small practices face, particularly in public procurement systems that prioritize experience with similar projects over innovation. He underscores how these constraints reinforce existing power dynamics, limiting opportunities for experimental firms to influence larger, more public-facing architecture.

While openly critical of industry institutions such as RIBA for failing to support emerging architects and condemning exploitative working practices in the profession, Barnes remains optimistic about the potential for architecture to inspire. He believes buildings that incorporate unexpected, “weird” elements can create meaningful connections with their users, offering moments of surprise and delight reminiscent of artworks.

Looking ahead, Barnes aims to extend his approach beyond affluent private commissions to a broader range of building types accessible to diverse publics. Despite ongoing challenges related to workload, compensation, and institutional inertia, his work and outlook suggest a shift toward an architecture that values joy, inclusivity, and individuality—qualities he views as overdue in the British architectural landscape.
