Sculptural suite in Berlin combines travertine, steel and curved walls

Inside AM TACHELES, the large urban development designed by Herzog & de Meuron in Berlin’s Mitte district, Berlin based practice LOTTO Studio has conceived a series of domestic vignettes that blur the boundaries between interior design, installation, and contemporary living. Curated by Garth Roberts, SUITE 04 41 transforms the apartment into a carefully staged environment where furniture, architecture, and atmosphere operate as a continuous spatial dialogue.

Rather than imposing a decorative layer onto the existing apartment by Grüntuch Ernst Architekten, LOTTO Studio approached the interiors with restraint. The furniture arrangement avoids conventional domestic hierarchies, proposing instead a softer and more ambiguous way of inhabiting space. Communal and individual activities overlap through a layout that feels simultaneously residential and curatorial.

Across the apartment, custom furniture pieces are defined by subtraction as much as form. Bent and cut aluminum surfaces create tables, shelving, and display elements that appear lightweight yet architectural. Open gaps, perforations, and cutouts become spatial devices connecting floor, ceiling, furniture, and artwork into a continuous visual system.

These negative spaces also frame the apartment itself. Materials already present within the architecture are revealed rather than concealed, allowing the intervention to remain in conversation with the existing structure. The result is an interior language where furniture acts less as isolated objects and more as instruments for spatial relationships and future inhabitation.

The living room unfolds as the first curated scene. A custom wool rug produced with CC-Tapis anchors the space, pierced by a floor to ceiling lamp constructed from industrial aluminum heatsink extrusions. Nearby, a butter yellow leather daybed faces the window in dialogue with a burled maple chair, while artworks by Lucia Bachner introduce another layer of material tactility.

Moving toward the kitchen, an American walnut chair is paired with a varnished aluminum table punctuated by LOTTO Studio’s characteristic cutouts. Above, modular electroplated stainless steel shelving assembled through exposed rivets reinforces the project’s balance between industrial precision and crafted detail.

The bedroom adopts a quieter atmosphere. A low mattress rests on an aluminum frame backed by large metallic panels, while a sculptural cutout within the headboard frames artwork by Berlin based artist Anne Steinhagen. Opposite the bed, a curved stool carved from Emperador marble introduces a heavier material presence within the otherwise lightweight composition.

Throughout the suite, LOTTO Studio combines industrial materials with warmer domestic textures. Burled maple, American walnut, wool, aluminum, marble, and translucent drapery create a layered palette that feels simultaneously raw and refined. Curtains developed with Cure-tain and mounted using systems by IMRI Curtain Systems soften the interiors while reinforcing the scenographic quality of each room.

The project ultimately proposes a different vision of luxury, one rooted not in excess but in precision, atmosphere, and spatial sensitivity. Across the apartment, furniture, objects, and architecture remain deliberately incomplete without the presence of future inhabitants, allowing the interiors to function as open frameworks for living rather than fixed stylistic statements.
