Barn renovation project with minimally framed double-height sliding doors

Frameless Courtyard Glazing Between Existing Brick Structures

To the kitchen and guest accommodation building, IQ Glass designed a combination of frameless structural glazing and sliding doors positioned between the original brick piers. Three large fixed structural glass panels occupy the central openings, creating uninterrupted views across the courtyard while maintaining the rhythm of the historic masonry.

At either end of the elevation, slim sliding doors were engineered to slide discreetly behind the existing brick pillars. This arrangement preserves the appearance of the original building while allowing direct access to the courtyard. By positioning the glazing within and behind the existing structure, the architecture retains its agricultural character while benefitting from contemporary levels of light and transparency.

The result is a highly restrained approach to barn renovation glazing, using glass to enhance rather than dominate the retained fabric of the Northamptonshire property.

Double-Height Sliding Doors Within Historic Barn Openings

The most significant glazing elements of the project are the two double-height sliding doors installed into the former barn openings of the principal farm building. Positioned on opposing elevations, these large, glazed openings provide access from the courtyard and gardens directly into the dining area.

Rather than infilling the openings with conventional windows or doors, IQ Glass designed oversized slim framed sliding systems that exploit the full height of the existing barn apertures. Each installation reaches approximately 4.5m in height, preserving the scale and drama of the original openings while allowing daylight to enter from both sides of the building.

Because the historic openings had moved out of plumb over time, bespoke pressings were carefully detailed and recessed into the surrounding walls to create clean transitions between glazing and masonry. This attention to detail ensures that the new interventions feel integrated within the retained structure rather than applied to it.
