Bury Gate Farm

Bespoke replacement dwelling in the South Downs

Triple Glazed Windows in the South Downs for a Bespoke Replacement Dwelling 

Bury Gate Farm is a bespoke replacement dwelling situated within the South Downs National Park near Pulborough in West Sussex. Designed by Sandy Rendel Architects, the project replaces a dilapidated 1950s bungalow with a contemporary interpretation of a country house set within a parkland landscape. IQ Glass was appointed to design, supply and install an extensive architectural glazing package, including large elevations of triple glazed windows in the South Downs, slim sliding glass doors and frameless structural glazing. Together, these elements play a defining role in shaping the home’s relationship with its landscape while delivering high levels of thermal performance. 

Landscape Context and Planning Challenges 

The site sits on rising ground at the edge of mature oak woodland, with expansive views opening out across the South Downs to the south and west. As part of a protected National Park, the design was subject to strict planning scrutiny, requiring a landscapeled approach and careful control of scale, massing and materiality. 

The architectural intent was to create a modern villa or small country house that drew on local parkland precedents rather than traditional farm buildings. This approach demanded a strong formal southern elevation, articulated through a twostorey colonnade, while ensuring the building remained visually calm within the wider landscape. Large areas of glazing were essential to frame views and bring light deep into the plan, but these had to be carefully balanced with energy efficiency, wind loading and longterm durability in an exposed rural setting.

Triple Glazed Windows as a Primary Architectural Element 

IQ Glass engineered and installed a wide range of oversized triple glazed windows in the South Downs, including fixed, tilt and turn and casement configurations distributed across both floors of the house. These windows are deliberately large in scale, with many extending floor-to-ceiling to reinforce the building’s relationship with the surrounding parkland. 

The firstfloor windows mirror the glazed openings below, helping to establish a generous doubleheight hall at the centre of the house. On the north and east elevations, floortoceiling tilt and turn windows maximise daylight to circulation spaces while ensuring controllable ventilation and comfort. All window systems were specified with thermal break technology and triple glazing to support the project’s ambition for a lowenergy, allelectric home. 

Slim Sliding Glass Doors and Structural Glazing Integration 

Along the primary southern elevation, IQ Glass installed a series of slim framed sliding glass doors opening onto the colonnaded terrace and gardens beyond. These doors create a seamless transition between interior and exterior spaces, allowing the principal living rooms and bedrooms to engage directly with the landscape. 

Several of the sliding door installations incorporate oversized glass units and flush threshold detailing, enabling uninterrupted movement between inside and out. Above the main dining space, frameless structural glass was installed to form a large, fixed window within the doubleheight void, aligned precisely with the sliding door geometry below. This alignment reinforces the architectural rhythm of the colonnade while allowing daylight to penetrate deep into the heart of the house. 

High Performance Glazing, Exposure and Craftsmanship 

Given the site’s exposed position within the South Downs, the glazing package was engineered to withstand high wind loads without compromising slim sightlines or visual clarity. Triple glazing was selected not only for thermal efficiency but also to support comfort and stability yearround in a rural environment. 

The glazing works contribute to a broader environmental strategy that includes high levels of insulation, renewable energy generation and mechanical ventilation with heat recovery. Within this context, the architectural glazing enables generous openness and transparency while remaining consistent with the calm, ordered character of the building. The project demonstrates how triple glazed windows in the South Downs can be used at scale in a landscapesensitive setting without visual heaviness.
