Sustainable New Build in Cornwall with Large Glass Doors

Frameless effect glazed systems were used to full effect in this unique sustainable new build home in Bodmin, Cornwall. The house nestles against a grassy slope overlooking the Cornish coastline and uses natural, complementary materials that integrate with the surrounding Cornwall countryside.

One half of the home is clad in Cornish slate, while the second half uses sustainably sourced timber to create a beautiful rustic aesthetic. The beauty of these materials is enhanced by minimally framed and frameless architectural glazing solutions. 

A minimal glazed link bridges the gap between the two buildings, which both feature large fixed frameless windows and slim sliding glass doors to capture the stunning views of the surrounding coast and sea. The simple glass box that protrudes from the house uses timber posts to structural glass walls, contrasting the Cornish slate to tie the two halves of the home together.

Minimal sliding glass doors run the length of a large open plan living area on the ground floor of the timber section, giving seamless access to the external decking area, which is dotted with lounge chairs for the homeowners to soak up the sun on warmer days. The extensively glazed elevation created by the ultra-slim framed sliding doors also ensures that the living space is flooded with natural light all year round.

Meanwhile, large vertical fixed aluminium casement windows run along the upper floor to provide a steady influx of natural light into the bedrooms. Using such a large amount of glazing on the south-facing elevation maximises the hours of sunlight enjoyed by the occupants during the day.

In order to counteract any excessive solar gain produced by receiving so much natural light, a solar control coating was applied to each of the glazed units, preventing the internal living spaces from overheating during the sunniest parts of the day.

Timber detailing was designed to surround some of the architectural glazing, following a seamless design where the glazing sits within the timber posts. The minimal glass box extension uses timber posts to structural glass walls for an effortless combination of materials and the IQ team of designers focused on the global alignment of timber elements with the glazing.

On the stone-clad section of the property, the small glass box extension protrudes out onto the grassy slope to create a cosy seating area that benefits from panoramic views or the breathtaking Cornish landscape.

Two of the three glass walls are made up of IQ’s Invisio thermally broken structural glazing, while the third elevation is a set of minimal sliding glass doors that allow easy access to the decking and garden area outside. Using timber posts allowed all glazing fixing details to be concealed, creating a frameless glass effect that contrasts the warm timber tones.  

Around the corner, the square end of the building features a further two sets of sliding doors that run the width of the upper and lower floors, taking advantage of the breathtaking views looking directly across the sea.


Frameless structural glass balustrades were installed across the sliding door opening on the first floor, to create a Juliette balcony arrangement that allows the homeowners to enjoy the full ventilation created with the doors fully opening, while still ensuring their safety.
