Church Hill Barn | A multi award-winning Grade II Listed barn conversion

Church Hill Barn is an award-winning Grade II Listed barn conversion set within the Suffolk countryside on the Essex/Suffolk border. Designed by David Nossiter, a recognised specialist in the sensitive transformation of historic agricultural buildings, the project reimagines a former model farm as a contemporary rural home.

Award-winning recognition for Church Hill Barn

Winner of best restoration in the Sunday Times’ British Homes Awards and shortlisted for the Daily Telegraph Homebuilding & Renovating Awards and the Architect’s Journal Retrofit Awards, the barn was originally part of the Assington Hall Estate. The cruciform barn and its surrounding outbuildings once accommodated multiple farming activities beneath a single roof. Today, the cathedral-like central volume, rising to eight metres with exposed timber trusses, forms the heart of a remarkable self-build home.

Retaining character whilst adding light

From the outset, the ambition was to retain the raw historic character of the barn while introducing expansive, light-filled living spaces. As a Grade II Listed structure, the scheme required close collaboration with conservation officers. Existing openings were preserved wherever possible and glazed – with glass deliberately set back from the external wall line to maintain the visual contrast with the brickwork. For IDSystems, the project demonstrates how carefully specified glazing can become a defining architectural element of a listed barn conversion, unlocking light while respecting heritage constraints.

Transforming the interior design

Glazing plays a pivotal role in transforming the interior, with fixed frame picture windows and the large panels of Grand Slider II sliding doors open the central space onto the courtyard and surrounding fields. These large glazed elements frame rural views while allowing for a seamless transition between inside and out. The aluminium frames contrasting with the brickwork and exposed timber roof structure, allowing the original architecture to remain visually dominant.

Interior daylight is further enhanced by two rooflights, positioned to draw natural light deep into the tall central volume. These rooflights help to light up the historic roof trusses and emphasise the barn’s height – whilst also reducing the reliance on artificial lighting.

Enhanced performance and efficiency

Achieving modern performance standards within a historic envelope was equally important. The roof was refurbished using a warm roof construction, placing insulation above a new timber deck so the original structure could remain exposed internally. External walls were insulated with sheep’s wool and clad in naturally weathering larch, while reclaimed materials from other agricultural buildings on site were reused wherever possible. High-performance glazing works in conjunction with underfloor heating and a mechanical ventilation with heat recovery system, ensuring thermal efficiency despite the large expanses of glass.

Church Hill Barn stands as a benchmark for contemporary barn conversions. It demonstrates how architectural glazing, when thoughtfully integrated, can reconcile heritage sensitivity with modern living — revealing rather than competing with the historic character of a listed rural building.
