A skylight is a window placed on a roof, which is generally positioned at an angle so that natural light from the sky can illuminate the interior space below it.
Architects and designers often use skylights in their projects as an alternative to traditional windows, whether it is for the purpose of giving a building a greater sense of privacy or simply as a decorative source of light.
A similar effect can be reached by installing clerestory windows, which are windows that sit very high up on walls.
From a weekend retreat in Norway to an Australian island home, we have collected 10 residential interiors with striking skylights.
This is the latest in our lookbooks series, which provides visual inspiration from Dezeen's archive. For more inspiration see previous lookbooks showcasing compact bedrooms, innovative room dividers and self-designed studios by architects and designers.
The curved openings were carved out of the property's white plaster ceiling, while rectilinear glass doors also contribute to the home's airy atmosphere.
Called Oculi House, the project was shortlisted for a 2019 Dezeen Award in the house interior of the year category.
Norweigan studio Line Solgaard added darker cabinets and flooring to the kitchen, which contrast with the shafts of natural light that flood the space and create dramatic shadows.
A mid-century armchair and rounded Muuto coffee tables sit beneath clerestory windows at Casa X, a home on Australia's Phillip Island by Branch Studio Architects that also has a number of large skylights.
"Three 'pop-up' high-level windows or light-catchers allow northern light to penetrate deep into the house throughout the day," explained the studio.
Pops of colour brighten up the spacious interior. In the kitchen area, a teal-hued, funnel-shaped extractor fan is suspended above a long marble counter.
Natural light enters this Chelsea apartment via an angled skylight that illuminates the dwelling, which is located on the ground floor despite its name, Photographer's Loft.
Architecture studio Yoshihara McKee removed the apartment's existing full-height partitions in order to make the most of the skylight, which frames sculptural furniture in neutral shades.
The multicoloured glass was added to the building's triangular timber roof in a position that means that light is cast all over the interior spaces.
"As the angle of the sun changes throughout the day and season, so do the visual effects within the living space, creating a vibrant show of coloured light throughout," explained Tres Birds.
Chilean architect Rodolfo Cañas also inserted a floating metal staircase into the volume, which leads to the roof. Monochrome furniture was chosen to mirror the palette of steel and exposed concrete used throughout the house.
Each of these openings is arranged above five cement-clad volumes that are positioned within the minimal project, which is aptly named House with a Light Void.
Casa Boavista is a Porto townhouse located on a busy street, which was renovated to include skylights on multiple levels to afford the property a sense of privacy.
Pablo Pita Architects added an extension to the back of the house as well as a new storey on top of it, while a trio of skylights illuminate the neutral interiors in three different places.
A bold colour palette takes centre stage in every room of this Victorian London home that was livened up by local practice R2 Studio.
Central to the renovation is one of two feature staircases, which has a bright orange hue accentuated by a skylight that adds warmth to the already colourful interiors.
