MMB

What MMB does

Modellbau Milde Berlin (MMB) is a Berlin-based, privately held precision model-making company founded around 1970 (firmographics indicate 1975), operating continuously for over 50 years from a workshop in the Berlin-Weißensee district. The company designs, fabricates, and delivers custom physical models and exhibits for four primary customer segments: architecture and real estate developers (competition models, presentation models, interior and urban planning models, real estate marketing models), museums, exhibitions, and trade shows (exhibits, reproductions, and educational displays), contemporary artists and art institutions (fabrication of sculptural installations and art objects), and — to a lesser extent — industrial design studios requiring prototypes and small production runs.

MMB's product portfolio is organized into five service lines: Architekturmodelle (architecture models), Designmodelle (design models and prototypes), Exponate (exhibits), Interaktive Modelle (interactive models with LED lighting, touchscreen control, and motion), and Kunstrealisation (technical realization of art projects). The underlying technology stack combines traditional craftsmanship with digital fabrication: 2D/3D CNC milling, 3D printing, laser cutting for detailed facade elements, and integration of multi-material assemblies using Corian, acrylic glass, polystyrene, resin, wood, aluminum, steel, and natural stone decors. The interactive model line, demonstrated by the 2022 Referenzkraftwerk Lausitz commission for Energiequelle GmbH, embeds approximately 1,600 individually programmable LEDs in Corian surfaces and synchronizes them with touchscreen control systems for energy-flow visualization and animated lighting effects — a technical differentiator at the high end of the market.

The business model is project-based, sales-led, and entirely custom: clients (architects, real estate developers, museums, corporate enterprises, and artists) commission bespoke projects on a one-time basis, pricing is not publicly disclosed, and acquisition is driven by portfolio referrals and direct outreach rather than paid marketing. Revenue is generated per project, with no recurring subscription, licensing, or productized offering. The company is owner-operated by Dipl. Ing. Constantin Unterberg, supported by a small interdisciplinary team of approximately six named professionals and a broad external partner network used to flex capacity on complex commissions. Distribution is direct and regional (DACH-region core, with selected international projects in Switzerland, Monaco, the Netherlands, and global contemporary art contexts); there is no retail, e-commerce, or digital self-service channel.

Core offering

Modellbau Milde Berlin (MMB) manufactures bespoke physical models for architecture, design, museums, exhibitions, trade shows, and contemporary art. Their work ranges from traditional wooden and plastic models to complex interactive exhibits integrating LED lighting, touchscreen controls, and motion. They serve architects, real estate developers, museums, artists, and industrial designers across Germany and Europe.

Product overview

MMB (Modellbau Milde Berlin) is a precision model-making company with over 50 years of experience, offering custom architectural, design, and artistic models. The company's core product portfolio comprises five main service lines: Architekturmodelle (architecture models for interiors, presentations, real estate, competitions, and urban planning), Designmodelle (design models, prototypes, and small series for product development), Exponate (exhibits for museums, exhibitions, and trade shows including reproductions), Interaktive Modelle (interactive models with lighting, control systems, and movement capabilities), and Kunstrealisation (art fabrication and project realization services for artists). Together, these offerings enable clients from architecture, real estate, design, museums, and the art world to visualize, present, and test their concepts through physical models ranging from traditional wooden models to complex interactive exhibits.

Direct peers

• Heatherwick Studio: Design and architecture studio with strong fabrication capability for sculptural, exhibition, and architectural-scale physical models. Direct analogue in combining architectural vision with hands-on model-making and material experimentation.
• Atelier Brückner: German design studio specializing in museum, exhibition, and brand-space scenography. Comparable to MMB in producing high-craft, interactive physical installations for cultural and commercial clients.
• Modellbau Weisser: Long-established German precision model-making workshop also focused on architectural, design, and museum models. Direct competitor in the same niche, serving architects and cultural institutions with comparable CNC/3D-printing workflows.

Emerging players

• Shapeways: On-demand 3D-printing marketplace that supplies architectural massing models, prototypes, and design objects. Adjacent competitor in the lower-cost, digitally-fabricated model segment.
• Local Projects: US-based experience design firm that builds interactive museum and exhibition installations. Comparable in the interactive/exhibit segment where MMB's LED- and touchscreen-driven models compete.
• Materialise: Large-scale industrial 3D-printing service provider with dedicated architectural and prototyping offerings. Represents the digital-fabrication competitor encroaching on traditional model-making workflows.

Broad incumbents

• BIG (Bjarke Ingels Group): International architecture firm with significant in-house model-making capacity for competitions and client presentations. Comparable in the sense that MMB supplies the kind of bespoke models BIG produces internally.
• Foster + Partners: Major global architecture practice that operates an in-house model shop. Overlaps with MMB's architecture-model work but at much larger scale and as part of a full design practice rather than a specialist model-making firm.
• Ralph Appelbaum Associates: Largest dedicated museum exhibition design firm globally, producing physical models, interactives, and interpretive installations. Overlaps with MMB in museum model and exhibit fabrication for cultural institutions.
• Herzog & de Meuron: Swiss architecture practice with a dedicated in-house model workshop (Modellbau). Functions partly as an internal model shop but engages external specialists for complex, interactive, or competition-scale projects similar to MMB's offerings.
