Killian is an accomplished interior & architectural designer whose work bridges forward-thinking architecture and richly layered interiors. With over a decade of professional experience across leading global design practices, Killian brings a refined eye for colour, spatial flow, and curated materiality to every project he touches.

Beginning his career in architecture and design in 2012, Killian has amassed diverse experience in both architectural and interior roles — from early architectural assistant positions at respected firms to senior design roles shaping complex, high-end interiors. He has contributed to projects that balance functionality with poetic design expression, always attentive to how people live, work, and feel within a space.

Most recently, Killian worked as an Associate at Martin Brudnizki Design Studio (MBDS), an internationally acclaimed interior architecture and design practice based in London and New York. MBDS is widely recognised for creating bespoke interiors that exude craft, charisma, and experiential richness — from luxury hotels and refined residences to celebrated hospitality spaces worldwide.

At MBDS, Killian headed up their residential department in New York and has played a key role in developing concept and design strategies across large-scale residential and hospitality environments, contributing to spaces that balance narrative depth with layered materiality. His design approach emphasises the integration of colour, texture, and proportion to craft curated interiors that feel both intentional and uniquely personal.

Before his tenure at MBDS, Killian held senior design positions at practices such as Dowen Farmer Architects and Bryan O’Sullivan Studio, where he was involved in Interior design, architectural detailing, strategic planning, and design development across residential and mixed-use projects.

Killian’s work is rooted in a belief that great design is both functional and evocative — that colour can enhance mood, that space should feel intuitive, and that every element in an interior should be purposefully curated. Whether reimagining a city residence or shaping a bespoke hospitality experience, his designs reflect a commitment to thoughtful composition, refined craftsmanship, and memorable spatial narratives.
