The former agricultural building is prominently located in the centre of Kressbronn, close to the village's town hall and festival hall.
Steimle Archiekten preserved the old barn's character whilst converting it into Kressbronn Library.
The studio also built a new forecourt and outdoor terrace to connect it to the nearby buildings.
Originally the agricultural building featured a steeply pitched roof with overhanging eaves sheltering a threshing floor above a storage space and stables.
These two levels have been preserved for the community centre and library.
"By maintaining the existing urban structure, with no external addition and no change to the striking, deeply overhanging saddleback roof, the preservation-worthy historical building fabric was strengthened," said Steimle Archiekten.
Modern materials are used but designed to evoke the original construction.
Between the roof and the concrete base, the barn's traditional horizontal clapboard siding has been replaced with vertical wooden slats that are rotated in varying degrees.
The slender angled boards allow diffused daylight to enter the library and create a dynamic effect across the building's facades.
The ground floor's stone walls have been replaced with an insulated concrete base.
Deep reveals in the base evoke the solidity of the earlier structure.
Large, glazed openings inserted into the concrete surfaces allow more daylight to reach the interior.
A concrete core connects the multipurpose ground-floor lobby with a library on the first floor and an open gallery tucked in beneath the preserved timber trusses.
"The library on the first floor, with its media and magazine gallery and its reading stations, offers surprisingly open views though the entire building," the studio added.
"Here in particular, the old and the new enter into an exciting dialogue. The balance of past and present becomes the building's special quality, not only from the outside but especially from the inside."
