Mount House

Frameless glass link links one dwelling to another

Mount House features a frameless glass link in Kent, connecting a traditional red brick country home with its contemporary extension. Located within the High Weald National Landscape, the property underwent a major renovation to create additional living accommodation and improve connections between the buildings.

IQ Glass designed and installed the structural glass link using its in-house developed Invisio system. The wider glazing package included an internal glass pivot door, Sieger aluminium casement and sliding doors, and fixed gable end glazing. Project partners included Marshall Carley Architects and Ciel Interior Design.

A transparent connection between the original house and extension

The renovation required a sheltered connection between the original dwelling and its extension that would retain views of the existing red brick architecture. Frameless structural glazing provided a transparent enclosure, allowing the original external walls to remain visible through the new corridor.

The frameless glass link in Kent uses glazed walls and a glass roof to introduce daylight into the connecting space. Its minimal appearance allows the traditional house and contemporary extension to retain their individual architectural character.

Inside the corridor, the same floor finish continues from the main living accommodation. This continuity helps connect the spaces visually, while the clear glazing maintains views through the link and towards the surrounding property.

Invisio structural glazing with an internal pivot door

IQ Glass used its Invisio structural glazing system to create the link’s minimal glass enclosure. The thermally broken system supports an insulated connection between the buildings while keeping visible framing to a minimum.

A frameless internal glass pivot door provides access between the corridor and the main living accommodation. Its transparent design maintains sightlines through the connection when closed, with the pivot mechanism providing the opening movement.

Sliding doors and fixed glazing complete the gable elevation

The extension combines Sieger slim sliding doors with fixed gable end glazing, creating a glazed elevation that follows the pitched roof form.

The sliding doors use a two-pane arrangement, with one pane sliding behind the other when opened. Above them, triangular fixed glazing brings daylight into the upper part of the living space.

The doors provide direct access to the outdoor seating area. A flush threshold detail supports movement between the extension and patio, allowing the homeowners to use the internal and external living spaces together.

Performance considerations

Thermal insulation was important to the frameless glass link in Kent because it forms an enclosed route between the two buildings. The Invisio system’s thermal breaks reduce heat transfer through the structural glazing connections, supporting the link’s integration with the internal accommodation.

A separate Sieger aluminium casement door provides another external entrance. Its thermally broken aluminium framing combines a slim appearance with insulation at this opening.

The glass roof and walls introduce daylight into the corridor, while the extension’s gable glazing admits light above the sliding doors. Opening the sliding doors provides ventilation and access to the garden, with the flush threshold reducing the level change at the doorway.

Technical details

  • Structural glazing system: Invisio, developed in-house by IQ Glass.

  • Glass link: Frameless structural glass walls and roof with thermally broken system connections.

  • Internal opening: Frameless glass pivot door.

  • External casement door: Sieger slim aluminium casement door with thermally broken framing.

  • Sliding doors: Sieger slim sliding doors in a two-pane configuration, with one pane sliding behind the other.

  • Gable glazing: Fixed triangular glazing above the sliding doors.

  • Threshold detail: Flush threshold at the extension’s sliding doors.

The completed frameless glass link in Kent provides Mount House with a sheltered connection between its original accommodation and contemporary extension. Transparent glazing retains views of the red brick exterior, while continuous flooring creates visual continuity through the corridor.

Within the extension, sliding doors and fixed gable glazing bring daylight into the living space and connect it with the garden.
