The British studio led by Magnus Ström designed the two dwellings, named Pyrus 9 and Pyrus 10, for the property developer Imola Förvlatning.
The imagery released to accompany the proposal is the latest in a series of photo-realistic renderings of Ström Architects' future projects and was created by 3D visualisation studio nu.ma.
The two almost-identical villas will be differentiated by their cladding and interiors, with one featuring blackened-timber cladding both inside and out, and the other ashy-grey.
The slightly larger of the two houses will be covered in the black-stained wood, while the smaller house will have the shell of lighter-toned wood.
"The two villas share a common design language, yet they have their own identity," explained Ström.
While each property will be three storeys tall, the hillside plot means just a small portion of the upper floor will be visible from the street, where two driveways will be separated by a low board-marked concrete wall and framed by planted borders.
But at the northern end of the site the full scale of the two rectilinear blocks will be exposed, where they cantilever out over a small concrete wall.
A tiered garden set between the two properties will step up in the centre to screen patios adjoining the glazed living spaces and guest bedrooms. These will be located on the top floor of each home, alongside an entrance hall and cloakroom.
Ström Architects, which ranked 126 on Dezeen Hot List, frequently works with highly skilled architectural visualisers such as nu.ma and The Boundary on their projects.
Earlier this year the studio completed a retirement home in the English countryside, a project that Henry Goss of The Boundary created atmospheric renderings of back in 2014
