For our latest lookbook, we've chosen 10 residential glass extensions that create airy, light-filled and modern additions to homes.
Glass is a popular material for house extensions as it is durable, weather-resistant and – thanks to its transparency – adds light and brightness to a space.
While glass extensions are common in cities all over the world, many examples in this lookbook are found in homes in London, where demand for extra space continues to increase.
The transparent extensions have been constructed to provide additional space to an existing building and are often used by residents for socialising, dining and entertaining.
This is the latest in our lookbooks series, which provides visual inspiration from Dezeen's archive. For more inspiration see previous lookbooks on homes framed by shutters and louvres, interiors with cork walls and homes that make use of board-formed concrete.
Tower House, UK, by Dominic McKenzie Architects
The lofty structures often found in rural Italy informed Dominic McKenzie Architects' brick extension for this home in Islington, London.
The studio added black glass-panelled French doors that open out onto a sunken garden, while a rectangular skylight above allows light to filter into the dining area from overhead.
Only minor changes were made elsewhere in the home. The pre-existing joinery was repainted and a Carrara marble fireplace was installed in the living room at the front of the house.

Floating Farmhouse, US, Tom Givone
Designer Tom Givone hoped to combine archaic and modern elements in his renovation of Floating Farmhouse, a two-storey home in rural New York that overlooks a picturesque creek.
After installing a large wall of glass at the front of the waterside kitchen, he finished the space with a polished concrete floor and a wood-burning stove, while the original colonial touches such as exposed beams and white-painted timber cladding were left intact.

London-based architecture studio HÛT removed this home's existing brick extension and replaced it with what the architects described as a "jewel-like glass box extension" that opens onto a sunken patio.
"The glass box helps bring daylight deep into the centre of the house where the kitchen is located and gives views into the lovely garden," the studio said.
In the rest of the property, the architects decided to keep the original historic features wherever possible, in particular making a statement with the listed building's staircase.
