Studio Peregalli practices one of the more intellectually rigorous forms of interior design working today, and its lineage matters here: both principals trained under Renzo Mongiardino, whose scenographic, theatrically layered approach to interiors remains one of the most influential and difficult-to-replicate design philosophies in the field. What Peregalli produces isn't decoration so much as invented history, interiors deliberately constructed to feel as though they accumulated organically over centuries, achieved through genuinely painstaking means: hand-painted walls, antique materials sourced rather than reproduced, custom boiserie, and sustained collaboration with specialist artisans practicing traditional crafts increasingly rare elsewhere. That level of ambition requires multi-year project timelines and correspondingly serious budgets, which is an honest trade-off for work this considered rather than an inflated markup. The two Rizzoli monographs, The Invention of the Past and Grand Tour, have documented and elevated the studio's reputation within design circles specifically, cementing its status among peers rather than relying purely on commercial visibility. This is design for clients who genuinely want narrative depth and craft authenticity over quick transformation, and value should be judged accordingly, as a serious artistic and historical investment rather than conventional interior decorating.
