Reimagining a Medieval Structure for Modern Living
A stunning project that redefines what it means to live within history. We were invited to develop the overall scheme and interior design for this extraordinary medieval Cotswolds Stone barn, located in the grounds of a listed Manor House. Fowler Architecture & Planning had achieved planning consent to convert the structure into habitable space, and the client brought us in to ensure the concept and detailing fulfilled the full potential of this ambitious transformation. The aim was to breathe new life into a long-disused agricultural building, while preserving its integrity and poetic simplicity.
Respecting the spirit of the original:
The key to the brief was balance: to respect the age, scale, and inherent character of the building while introducing a quietly modern sensibility. The design sought to honour the barn’s organic materials, its weathered limestone walls and hand-hewn timber trusses, without overwhelming them. Our approach was one of lightness and restraint: to let the building’s history speak, and to frame its beauty through proportion, texture, and natural light.
A sculptural centrepiece:
At the centre of the project sits a dramatic self-supporting sculptural staircase, conceived as both structure and artwork. The client had envisioned a statement piece in stone, and the collaboration with master stonemason Ian Knapper was a defining aspect of the process. Crafted from French limestone, each tread was individually sculpted, spiralling upward with grace. The rusted wrought iron balustrade sweeps through the space, catching light and shadow as it leads to a mezzanine lounge and home office beyond. This staircase gives the interior a sense of movement and permanence, a sculptural gesture that anchors the open volume.
Material honesty and craft:
We designed bespoke joinery throughout in band-sawn oak of random widths, echoing the barn’s agricultural heritage. The oak grain was left expressive, textured rather than polished, to retain a sense of handcraft and authenticity. Flooring in reclaimed oak follows the same principle, laid in random widths to avoid modern uniformity and to celebrate imperfection. These elements bring warmth and rhythm to the stone interior.
Light as a design material:
Lighting was a critical part of the design. We treated light not simply as illumination but as an architectural material, one that reveals surface, scale, and time. Carefully positioned fittings highlight the texture of the ancient stone walls, while concealed lighting washes the gable end and timber beams in a soft, atmospheric glow. During the day, large glazed openings draw natural light deep into the interior, tracing the passing of the sun across stone and timber. The result is an interior that feels alive, serene, timeless, and always in conversation with the weather outside.
Continuity between eras
Our design philosophy for the barn echoes much of what we explore in our residential work: the dialogue between heritage and modernity, between material permanence and the lightness of contemporary living. The barn’s original fabric was retained and revealed wherever possible, while new insertions were expressed honestly as contemporary layers. The suspended wood-burning stove at the heart of the main space embodies this duality as it is traditional in spirit, yet minimal and sculptural in form. The hearth of the fireplace is crafted from the same french limestone as the staircase, it’s design is a nod to a traditional mill stone.
The result is a project that unites architecture, craft, and landscape. It remains unmistakably a medieval barn, yet one that now feels inhabited, human, and alive again, a place to experience light, weather, and material beauty throughout the seasons.
