Eight homes where internal windows and partitions maximise light
In this lookbook, we have collected eight projects that use internal glazing and partitions to create brighter home interiors and increased connectivity between spaces.
While the primary use of windows is for daylight access and ventilation, they can also play a key role in visually connecting spaces within the home.
Adding internal windows enables more interaction between adjacent rooms, while allowing light to penetrate further into the home – creating bright and spacious interiors.
While similar, internal partitions offer a unique opportunity to simultaneously increase connectivity and enhance privacy through the demarcation of a home's internal spaces.
Below are eight examples that showcase the versatility of internal openings and partitions, ranging from a colourful home extension featuring playful, circular windows in London to an open-plan kitchen punctuated with brass-lined portals in Toronto.
This is the latest in our lookbooks series, which provides visual inspiration from Dezeen's archive. For more inspiration, see previous lookbooks featuring creative guest rooms that accommodate visitors in style, home interiors brightened with colourful window frames and hotel interiors characterised by eclectic designs.
