Double Height Lightwells and Sliding Glass Doors

Double the Height, Double the Light

An inherent characteristic of untreated glass is its natural transparency and light transmission. It’s main purpose when used within architectural and building design is to introduce high levels of natural light into a space and to allow vision out of the house to promote a feeling of openness.

This is apparent in modern architecture’s trend towards large glass facades in contemporary design. Always the aim here is to give the feeling of being outside, to merge the boundaries with the garden and living spaces and promote healthy living using natural light.

In basement spaces where access to natural light is limited architects have to be inventive about the use of glass to allow this much needed resource into these sub ground level spaces. Here the use of glass light wells flourish. By introducing courtyards walled with glass recessed into a basement you can allow hours of natural light into these dark areas.

Obviously the call here is for minimal framing and large glass faces. IQ have used our sliding glass doors on a number of these light wells, these minimally framed opening doors mixed with clever use of frameless balustrades and structural glass, allow as much light to enter a basement space as possible.

On a recent project in Wandsworth IQ Glass used our sliding glass doors to the full rear elevation of the rear extension added. But below this large Victorian family home a large basement spanned the entire sub ground floor.

Here, to allow natural light into the windowless space, the minimally framed sliding glass doors extended downwards another floor creating a double height façade of this minimal glass.

Down in the basement these sliding glass doors now created a two sided light well made of near frameless sliding glass doors. These doors open to allow access to the courtyard and garden.

Frameless glass balustrades provide a safe barrier around the void both inside and outside without shading the much needed light well.
