Slim Sliding Doors for a Sustainable Cornwall House 

Stone Haven is a highly sustainable new build home set into a south facing slope on the Cornish coast. Designed to replace a former farmhouse within an Area of Outstanding Natural Beauty, the project balances contemporary architecture with a deep sensitivity to landscape and materiality. Local slate, sustainably sourced Shou Sugi Ban timber and slim, precision engineered glazing define the external character of the home. 

As part of a comprehensive architectural glazing package, the property incorporates multiple installations of slim sliding doors for the sustainable Cornwall house, using minimal windows® systems to achieve slender sightlines, expansive openings and panoramic coastal views. The home has been widely recognised for its environmental performance and refined design quality, winning the International Property Award for Best Residential Property.

Designing a Contemporary Coastal Home Rooted in Sustainability 

The architectural concept for Stone Haven was shaped by the site’s unique coastal setting and the ambition to create a home with exceptional environmental integrity. Woodford Architecture designed the building to sit quietly within the landscape, moulding it into the existing slope and using locally sourced materials to reduce embodied carbon. 

Inside, the home embraces generous volumes, warm textures and abundant natural daylight. Flexibility and comfort were prioritised, expressed through open plan living spaces framed by large areas of glass. This connection to nature was central to the brief, and minimal windows® played a critical role in achieving unobstructed, wide spanning views of the Cornish cliffs and sea. The slim framing enhances the calm architectural language of the interior while maximising the presence of natural light.  

Navigating Coastal Conditions, Solar Exposure and Heritage Constraints 

The project required careful resolution of environmental challenges associated with coastal architecture. The exposure to sea air meant that durability, corrosion resistance and long-term performance were essential considerations. The south facing aspect also introduced significant solar gain, requiring a glazing specification that could control heat while maintaining clarity. 

The planning context within an Area of Outstanding Natural Beauty meant that the house needed to integrate seamlessly with its surroundings. This influenced the decision to embed the building into the hillside, use natural materials and rely on slim framed glazing that would visually recede against the stone and timber envelope. Large openings were essential to the architectural experience, yet they needed to be detailed to withstand coastal climate conditions.  

How the minimal windows® Systems Delivered Performance and Design Precision 

minimal windows® sliding door systems offered the exact combination of durability, slim sightlines and environmental performance needed for Stone Haven. Their aluminium framing, finished in marine grade polyester powder coating, provided resistance to corrosion and ensured reliable long-term operation along the exposed Cornish coastline. Solar control coatings were applied to all external glazing to moderate internal temperatures and minimise glare throughout the year.  

Slim 21 millimetre sightlines were particularly important in the living room and master bedroom, where uninterrupted sea views formed a defining element of the architectural concept. In these rooms, large three pane minimal windows® doors were specified, enabling wide openings and providing a seamless transition between indoor spaces and the coastal landscape. 

The doors were strategically positioned to frame key views, enhance natural light and create strong visual continuity across the home. With multiple sliding configurations installed across both floors, the minimal windows® systems supported the building’s architectural rhythm while ensuring robustness and weather performance in a demanding environment.  

A Landmark Coastal Home Showcasing Slim Sliding Doors for a Sustainable Cornwall House 

Stone Haven exemplifies how contemporary coastal architecture can combine environmental responsibility with refined design. The home’s composition of natural materials, sculptural volumes and slim glazed elevations results in a place that feels both anchored in the landscape and enriched by its views. 

The use of slim sliding doors for a sustainable Cornwall house is integral to its architectural identity, enabling a level of openness, light and connection to nature that defines the experience of the property. For architects, developers and private clients seeking a premium glazing solution that excels in coastal conditions, Stone Haven demonstrates the capability, elegance and performance of minimal windows® systems at their best.
