The architecture firm Atelier Sunder-Plassmann designed the "Hof Ahmen" holiday home, a residential space integrated into a listed historical estate with surrounding meadows in Kopperby, a quiet district of Kappeln, Germany.

Hof Ahmen, characterized by a rectangular courtyard surrounded by meadows, features the main house at its center—defined by a thatched roof, a coppery beech tree, and centuries-old trees—and to the east of the main house are independent roofs conceived as an open timber structure for the former sheepfold. The holiday home is an extension of these independent roof structures, to which a fifth, floating roof has been added. 

The Hof Ahmen holiday home, designed by Atelier Sunder-Plassmann, is built around a floating, glazed platform that forms the main living space. Visitors enter the house via a terrace on the east side. This space serves as an outdoor area in summer and is an extension of the interior. From here, a large sliding door leads into the main living area.

The main living area is divided into three sections by a wall, without completely separating the space. The dining area is located in the southern section, and the living area in the northern section. In the central section, a built-in unit integrates the bathroom and visually separates it from the main living area, while opposite the wall unit, the kitchen is presented as a freestanding volume.

Two enclosed wooden cubes are inserted into the glazed platform, housing the private spaces and opening onto the main living area through sliding doors.

Project description by Atelier Sunder-Plassmann

The design for the vacation home Hof Ahmen goes back to the seemingly simple and yet essential question: How do I complement a unique, listed farm with surrounding grassland and integrate the new building into the “genius loci” of the farm, while at the same time developing an independent modern architectural language for the new building?

Hof Ahmen as an ensemble is characterized by a rectangular courtyard surrounded by permanent grassland, which is separated by the typical local bends. In the middle of this rectangle stands the listed, thatched main house with a copper beech and lush, historically grown trees. To the east of the main house are the detached roofs of the sheep barn, which was built in 1990 as an open wooden construction and in its pro- portions and roof shape correspond to the typical local „Drempel barns“.

The cottage forms an extension of these freestanding roof structures and a fifth, floa- ting roof is added. The new building incorporates the „genius loci“. A floating platform, which is inserted under the roof, forms the main space of the cottage and a threshing floor is created. This platform is completely glazed and the boundary between inside and outside becomes blurred. The interior space expands to the exterior space and a garden house is created. Analogies to the classics of modernism, the "Glass House“ by Phillip Johnson and the „Farnsworth House“ by Mies van der Rohe emerge.

The occupant becomes an observer of nature and the environment becomes the main pro- tagonist of the interior. A staging of nature; slightly elevated from a kind of pedestal, the resident observes the surroundings, the constant interplay of cloud formations, the seasons and the grazing of sheep in front of the cottage determine the atmosphere and character of the cottage and the surroundings become a scenery, a backdrop.

The complete beauty of nature opens up to the user
The visitor enters the cottage through a terrace, which is located in front of the cottage in the east. This serves as an outdoor area in summer and is an extension of the interior. From here, through the large sliding door (2.4m x 3.4m), one enters the main room. In its proportions (4 x 10m, 4.1m clear height) based on the barns of classic longhouses, the cottage seeks here the dialogue between, on the one hand, rural, typical local typologies and classical modernism.

The main room is subtly divided into 3 areas by an inserted wall element, without dividing the space in its entirety. The southern area, which gets sun all day long, is the dining area with its generous free-standing table. The northern area, where the sun shines from 5 o‘clock in the evening, is the living area. In the central area, the furniture element integrates the wet area and visually separates it from the main room. In front of the set wall unit, the kitchen floats as a free, mirrored volume.

Two wooden cubes are inserted into this fully glazed platform, which accommodate the sleeping berths. These closed volumes form a retreat in contrast to the open main space and convey a sense of security. The cubes can be opened to the main space through generous sliding doors, allowing flexible uses of the sleeping berths (daybed, couch) in conjunction with the main space.

The border between integration and segregation, between landscape and architecture, between rural and modern, between open and modern and the careful balancing of these elements determines the design and let the cottage together with the lush nature become a unique place.

Atelier Sunder-Plassmann is a young architecture office based in Berlin and Kappeln, influenced by the Nordic background of its founder, Malte Sunder-Plassmann.

After graduating with a Master of Arts from UdK in Berlin, Malte Sunder-Plassmann gained his first work experience at Sou Fujimoto Architects in Tokyo, Studio Barozzi Veiga in Barcelona, Nieto Sobejano Arquitectos in Berlin, and by collaborating with the architect Alfred Sunder-Plassmann.

The journey of Atelier Sunder-Plassmann started in 2022 when the first project, the holiday house Hof Ahmen, was completed. This tiny house, addressing the boundary between nature and architecture, was nominated for many architecture and best young office awards in 2022. The project was published in several magazines and books.

The second project of Atelier Sunder-Plassmann was also completed in 2022: the aichermagazin, a temporary exhibition pavilion in Isny im Allgäu showcasing the work “the city in black and white” by Otl Aicher. The aichermagazin was nominated for the German Design Award 2022. Starting with these two projects, Atelier Sunderℙlassmann expanded the scale of its projects and is currently working on various projects in Germany.

The focus point of the work remained on housing, with several projects currently in design development or under construction. In addition to that, hotel and cultural projects became a center of attention.

Furthermore, Atelier Sunderℙlassmann participated in several competitions, such as the awarded Schleidörferzentrum Boren and the Arolsen Archive.
