SONAR Modular stainless steel System
SONAR is a handmade sculptural and high quality modular furniture system made from 2 mm brushed stainless steel, combining minimalist design with architectural presence.
The system consists of two precisely crafted elements — the SONAR Cube (open module) and the SONAR Body(closed module) — which can be used individually or combined into a versatile sideboard or larger architectural furniture structure.
SONAR Cube – The Heart of the System
The SONAR Cube is the core element around which the entire system can be built.
It is open on one side and closed on the back, offering practical space for vinyl records, books, and personal objects. The outer surfaces are brushed, while the interior is hand-finished using Scotch to achieve a matte, subtle texture.
Every Cube is fully welded, finely ground, and brushed by hand — resulting in clean edges, consistent surfaces, and a refined, characterful finish.
Because of its proportions and construction, the Cube integrates naturally into almost any configuration. Most modular combinations leave at least one open position where a Cube can be added — often in ways even we haven’t fully explored yet.
The Cube is also available as a standalone piece, functioning as a side table, display unit, or sculptural object.
Cube Dimensions:
Height: 40 cm
Width: 50 cm
Depth: 35 cm
SONAR Body – The Architectural Core
The SONAR Body is the most intricate and labor-intensive element of the system.
All edges are manually welded, ground, and brushed — a process that demands a high level of skill and expertise, especially when working with stainless steel. The result is a closed, monolithic form with crisp geometry and seamless transitions.
The Body slides halfway into the Cube to create a hybrid structure of balance, tension, and stability — forming a clean, architectural block when combined.
It can also be purchased individually, for use as a side table, console block, or sculptural furniture piece.
Body Dimensions:
Height: 50 cm
Width: 75 cm
Depth: 35 cm
Modular Design
SONAR is designed to adapt to the space and the person using it:
-
Use the Cube and Body independently
-
Combine them into a clean, architectural sideboard
-
Expand the system with multiple Cubes and Bodies
-
Create your own sculptural compositions with open and closed volumes
Each module is handcrafted in our own workshop, ensuring precision, durability, and a finish that celebrates the material itself — stainless steel as a statement of clarity, longevity, and understated strength.
