Located in a designated conservation area in Rutland, the dwelling has a principal wing dedicated to everyday use, and a smaller second wing with three bedrooms for visitors.
It was designed by Featherstone Young so that the guest zone would only be opened up and heated when the extra space is required, ensuring flexibility and limiting energy consumption.
"The client wanted a house that was both adaptable and energy efficient," explained the London studio's co-founder Sarah Featherstone.
"Their sons were teenagers when the project commenced so they knew that when the house was complete they would no longer be living permanently at home," she told Dezeen.
"This meant they wanted a house that was comfortable and worked well when only the two of them there but when their sons and their future families visited it needed to be able to accommodate them all."
Stonecrop measures 347 metres squared, and its angular wings fold around a central circular courtyard.
The main wing branches off a buffer wall on the rear side of the house, which is built from local limestone rubble and forms part of the dwelling's hybrid masonry and steel structure.
Stonecrop's striking aesthetic was developed to ensure the home complemented its surroundings – appearing as though it emerges out from inside the landscape.
Similarly, its materiality nods to its rural setting, dominated by the Clipsham limestone quarried a few miles away from the house.
"It is important that, being located within a village, the house is sympathetic to its character and that its design captures the sense of place," explained Featherstone.
"By this I don't mean copy the style of houses already there, but understand and interpret the local vernacular to create a new house rooted in place, but of its time."
The buffer wall's textured finish and limited windows is intended to "convey the sense of protection" while providing thermal mass.
It is contrasted with the guest wing of the house that is clad in the same limestone but with a smoother finish with larger windows.
Stonecrop's principal wing slots in between this buffer wall and the guest zone, where it emerges out and extends upwards with a white-rendered facade.
On its tallest side, it reaches five metres in height and opens out with large glazed areas that look out over the surrounding landscape.
Inside, Stonecrop's focal point is an open plan living area on the ground floor, with glossy red partition walls that are "treated like pieces of furniture" rather than extending to the ceiling.
Here, the external material finishes extend inwards where they are teamed with faceted cedar-clad ceilings and walls that feature throughout the house.
The home's more utilitarian spaces such as a the utility room and larder are housed in pod-like structures that extend out from the buffer wall.
This also includes a study, which is cantilevered from the highest floor to evoke an eyrie – the large nest of a bird of prey found high in trees or cliffs.
"Our clients have an interest in astronomy and love of trees, so we created a tree-house type eyrie located at the highest level of the house cantilevered off the stone buffer wall," said Featherstone.
"This space nestles within the surrounding trees and offers magnificent views across the surrounding farmland."
A visual connection to the outside is present throughout the entire house, offering occupants views out onto the series of different gardens.
Landscaped by John Dejardin, these gardens each are positioned all around the house and each serve different purposes such as planting or relaxing.
Featherstone Young is a London architecture studio founded in 2002 by Featherstone and Jeremy Young.
Other projects by the studio include a house cantilevered over a river in Wales, a day centre for homeless people in east London and a residential building within an old board-game factory.
