Ton Barn
Barn-Style Passive House in Cranborne Chase National Landscape
Nestled within the serene and protected landscape of the Cranborne Chase and West Wiltshire Downs Area of Outstanding Natural Beauty (AONB), this new barn-style dwelling exemplifies environmentally conscious design and sensitive integration with the rural surroundings. Overcoming stringent planning constraints, the project is a testament to collaborative design and sustainable building practices.

Commissioned by a private client, the project sought to create a contextually sensitive dwelling while achieving planning consent on a traditionally complicated site. The client also prioritised a design that adhered to Passivhaus principles, ensuring both energy efficiency and long-term comfort.
The site is surrounded by rolling hills, open countryside, and a rich mosaic of woodlands, hedgerows, and farmland. The rural character of the area is characterised by traditional agricultural buildings and barns, which inspired the project’s architectural language. The climate and topography required a design that could withstand seasonal variations while remaining unobtrusive in the landscape.
The internal layout is designed to maximize functionality and comfort, with clear zoning between public and private spaces. Living areas are positioned to take advantage of natural light and views, while service areas are discreetly tucked away. The open-plan design fosters a sense of spaciousness, while the use of large openings connects the interior with the surrounding landscape.
By adhering to Passivhaus principles and sustainable building standards, the design not only respects the landscape but also offers a forward-thinking approach to rural living. Key design choices, such as the use of Structurally Insulated Panels (SIPs), reinforce the narrative of a home that is both contemporary and environmentally conscious. This methodology not only optimises energy efficiency but also reduces the home’s carbon footprint. The prefabrication of SIPS minimises construction waste and time on site, while ensuring high levels of thermal insulation and airtightness—key components of the Passivhaus standard.
The project faced significant planning constraints due to its location in an AONB and proximity to a Conservation Area. Balancing the client’s aspirations with the need for contextual sensitivity required careful negotiation and collaboration with local authorities and agencies. The exposed rural site also presented challenges related to material durability and energy efficiency.
