Modelli architettonici: la guida definitiva

C 1.1: La definizione dei modelli architettonici

Sappiamo tutti che le competenze degli architetti sono essenziali per il successo di qualsiasi progetto di modellismo.

Ma il design non è l'unico aspetto cruciale. Anche la comunicazione durante il processo di progettazione è essenziale per il progetto di costruzione.

Gli architetti devono considerare come il progetto verrà tradotto dal progetto alla realizzazione vera e propria.

Pertanto, i modelli architettonici fisici 3D possono essere utilizzati per esprimere i progetti degli architetti.

Un modello architettonico è un oggetto fisico 3D che mostra versioni in scala di edifici esistenti o storici.

È considerato anche un oggetto di bellezza.

C 1.2: La storia dei modelli architettonici

Architectural models have been used for thousands of years, although their purpose has changed considerably over time. Early fired-clay building models dating to around 4600 BC were often symbolic or funerary objects rather than design tools.

Pottery building models also appeared in Han dynasty China. During the Renaissance, physical models became increasingly important for studying and presenting architectural proposals, particularly as buildings became more complex.

By the twentieth century, architects were also using conceptual models to explore form, space and experimental design ideas.

Today, physical models continue to support architectural design and communication, but digital design, laser cutting, CNC machining and 3D printing have significantly changed how professional models are developed and fabricated.

C 1.3: L'evoluzione dei modelli architettonici

I modelli architettonici sono strumenti eccellenti per concretizzare i progetti.

I modellisti scelgono i materiali in base ai dettagli precisi della facciata e realizzano gli spazi interni in modo autentico.

Alcuni modellisti creano modelli astratti per mostrare progetti irrealizzabili di proposte visionarie.

Questi modelli soddisfano i desideri visivi del pubblico, come la Endless House di Kiesler.

Al giorno d'oggi, insieme al Computer Aided Design e all'ingegneria del software per modelli architettonici avanzati.

Ad esempio, le macchine per il taglio laser e la stampa 3D possono realizzare modelli ad alta fedeltà con un livello di dettaglio e una precisione senza pari.

I modelli architettonici costituiscono un linguaggio artistico contagioso ed espressivo.

In particolare, è possibile utilizzare i modelli di presentazione nella progettazione urbanistica e architettonica.

Questi includono il case, resort, modello scolastico e altre strutture ed edifici pubblici, ecc.

Un modello di presentazione può essere utilizzato nella pianificazione urbana.

Per far fronte al rapido sviluppo della diversificazione del settore edile, questi modelli mostrano ai clienti le caratteristiche progettuali.

Ad esempio, la struttura, l'ambiente circostante, l'illuminazione e la ventilazione all'interno dell'edificio.

Come realizzare un modello architettonico senza errori sta diventando una necessità urgente.

Inoltre, dopo aver considerato gli attuali problemi ambientali globali e lo sviluppo sostenibile.

È importante sviluppare tecnologie verdi, compresi i materiali per la lavorazione dei modelli e i metodi per la realizzazione di modelli architettonici.

I risultati e le applicazioni dei modelli architettonici continuano a migliorare e innovare.

Ciò significa che la creatività architettonica continuerà a utilizzare modelli architettonici.

Architectural models support different decisions at different stages of a project, from early design review to sales, public communication, investment discussions and planning.

C 2.1: Comunicazione e panoramica

Architectural models help design teams and clients understand massing, spatial relationships, building form and site context in three dimensions. They can also make design issues easier to identify before later project stages.

C 2.2: Vendite e marketing

For real-estate developments, a physical model can help potential buyers and investors understand the building, unit locations, entrances, landscaping and surrounding environment before construction is complete.

C 2.5: Approvazione e permessi per progetti di costruzione

Where a physical model is requested or useful, it can help planning authorities and project stakeholders evaluate a proposal in relation to its site, neighbouring development and wider context.

C 2.6: Idea architettonica astratta e futura

Conceptual models allow architects and designers to explore forms, spatial ideas and proposals that are still evolving or may not yet be intended for immediate construction.

Un modello astratto

In genere, oggigiorno è possibile classificare i modelli architettonici in tipologie in base al loro utilizzo.

C 3.1: Modelli architettonici classificati per usi

C 3.1.1: Modello concettuale in scala

Conceptual models are used during the early stages of design to explore massing, proportion, spatial relationships and the relationship between a proposed building and its site.

They are usually simplified so that ideas can be tested and changed quickly rather than presented as finished architecture.

Materials such as board, foam and other easily worked materials may be used when speed and flexibility are more important than fine detail.

The value of a conceptual model is not realism. Its purpose is to help the design team compare ideas and understand the overall direction of a project.

Un esempio di modello concettuale

C 3.1.2: Modelli in scala funzionante

Working models are used as a design develops. They allow architects and project teams to test particular relationships, forms, façade treatments, components or construction ideas in greater detail than a conceptual model. Because they may be handled, modified or reviewed repeatedly, their materials and construction are often more durable than those used for quick early-stage studies.

A working model does not need to look like a finished presentation model. Its value lies in helping the team investigate a design problem, compare alternatives and refine decisions before the final design is presented.

C 3.1.3: Modelli in scala di presentazione

Presentation models communicate a developed architectural proposal to clients, decision-makers, buyers or the public. Compared with conceptual and working models, they normally place greater emphasis on finish, accuracy and the visual information needed for the intended presentation.

Depending on the project, a presentation model may include detailed façades, landscape, lighting, interior elements, roads, people, vehicles or interactive features. The appropriate level of detail should be determined by the model’s scale, viewing distance and presentation purpose rather than by adding as much detail as possible.

Un esempio del modello di presentazione, Ain Dubai

RJ Models’ Ain Dubai model is one example of a presentation model used to communicate a major development through a physical three-dimensional representation.

C 3.2: Modelli architettonici classificati per funzioni

C 3.2.1: Modello di piano generale

Master plan models show how buildings, roads, landscape, infrastructure and development zones relate across a larger site. They are useful for urban planning, development presentations, public consultation and real-estate marketing, where the relationship between individual buildings and the wider environment is more important than fine façade detail. RJ Models’ Doha City Planning Model was produced at 1:1000, measuring 26,000 × 26,000 mm, to communicate the future development of Doha, including new landmarks and the relationships between different districts.

Modello di piano generale

Some city and master plan models incorporate interactive features when the presentation requires them. These may include controlled lighting, touchscreens, projection or zone-based illumination. For example, RJ Models’ Istanbul Urban Planning Model was designed to synchronize with a projector to help viewers understand the city’s layout. Interactive features should therefore be selected according to the presentation purpose rather than treated as a standard requirement for every city model.

 

C 3.2.2: Modello di edificio per uffici

Office building models are used to communicate tower form, façade design, building entrances, podiums and the relationship between commercial buildings and their surroundings. Depending on the presentation purpose, they may also include lighting, landscape and interior indications. RJ Models created the 1:100 Swiss Re Tower model for Foster + Partners, measuring 500 × 500 × 1500 mm. The model focused on the tower’s distinctive curved form and complex multi-layered glass façade.

C 3.2.3: Modello di edificio residenziale

Residential building models help developers, architects and buyers understand building form, apartment locations, entrances, amenities, landscaping and the overall living environment. They are commonly used for design presentations and real-estate marketing. RJ Models’ 1:100 Opus Hong Kong model, measuring 1200 × 1200 mm, reproduced Frank Gehry’s distinctive residential tower design while using façade materials and landscaping to communicate the architectural character of the project.

C 3.2.4: Modello di villa

Villa models are usually produced at relatively large scales so that viewers can understand both the exterior architecture and, when required, interior spaces. Removable roofs, lighting, furniture, swimming pools and landscaping can be added according to the presentation purpose. For a villa project in KSA, RJ Models produced a 1:25 model measuring 1200 × 1200 mm, including detailed interiors, lighting, a swimming pool and surrounding landscape to communicate the residential experience.

C 3.2.5: Modello di centro commerciale

Shopping mall models help explain entrances, circulation, retail zones, façades, public spaces and the relationship between the mall and surrounding development. Lighting and selected interior elements can strengthen sales and investment presentations. RJ Models’ 1:150 Suzhou Center Shopping Mall Model measured 2000 × 800 × 800 mm and reproduced Benoy’s distinctive undulating glass canopy, using 3D printing and integrated lighting to communicate the project’s architectural identity.

Modello di centro commerciale

C 3.2.6: Modello di hotel

Hotel models can present the relationship between guest buildings, landscape, pools, recreational facilities and surrounding environments. The appropriate scale depends on whether the presentation focuses on the architecture, the resort master plan or detailed hospitality spaces. RJ Models produced the Madinat Jumeirah Hotel Model in Dubai at 1:400, measuring 2600 × 2600 mm, combining detailed resort buildings, landscaping and lighting to communicate the character of the development.

Modello di hotel

C 3.2.7: Modello dello stadio

Stadium models help communicate overall building form, roof structures, seating arrangements, entrances, surrounding facilities and the relationship between the venue and its site. Lighting and miniature spectators can also help demonstrate how the stadium operates during events. RJ Models produced the 1:500 RTA Stadium Model, measuring 2800 × 1500 mm, with separate interior and exterior lighting systems and approximately 3,000 miniature figures to create a realistic event environment.

Modello dello stadio

C 3.2.8: Modello di parco a tema

Theme park models combine architecture, landscape, attractions, circulation and storytelling within one physical display. Because visitors need to understand both the overall park layout and individual attractions, lighting, water features and moving or interactive elements may be incorporated where appropriate. RJ Models’ Dubai Park model was produced at 1:400, measuring 4800 × 4800 mm, and represented more than 100 attractions together with running and flashing lighting effects.

Modello di parco a tema

C 3.2.9: Modello museale

Museum models can be used for architectural competitions, design review, exhibitions and public communication. Depending on the design, the model may focus on overall form, structural geometry, internal galleries or the relationship between the building and its site. RJ Models created the 1:300 Yinchuan Museum Model for WAA, measuring 1200 × 1100 mm. Its monochrome presentation emphasized the building’s complex ribbon-like, double-curved architectural form rather than surrounding detail.

Modello museale

C 3.2.10: Modello industriale

Industrial models explain facilities, production areas, equipment, circulation and operational relationships that can be difficult to understand from drawings alone. They may be used for exhibitions, technical presentations, training or stakeholder communication. RJ Models produced the 1:120 Macallan New Distillery model in Scotland, measuring 2500 × 1400 mm, using advanced fabrication methods to reproduce the project’s distinctive flowing, grass-covered roof and its relationship with the surrounding landscape.

Modello di fabbrica

C 3.2.11: Modello di cantiere navale

Shipyard models show how workshops, warehouses, docks, slipways, vessels and other production areas work together across a large industrial site. They can support public presentations, operational explanation and development communication. RJ Models produced the Baku Shipyard Model in Azerbaijan at 1:750, measuring 2700 × 1500 mm. The model was developed from project drawings and reference photographs and used to communicate the shipyard development in a public-display setting.

Modello di cantiere navale

C 3.2.12: Modello di aeroporto

Airport models can focus on terminal architecture, passenger circulation, airport infrastructure or the relationship between an airport and the wider city. The required scale changes significantly depending on the information being presented. RJ Models created a 1:5000 model of Abu Dhabi International Airport’s Midfield Terminal Complex for KPF, measuring 1600 × 1500 mm. At this scale, roads, traffic systems, airport-city development and landscape were prioritized while the terminal architecture was carefully simplified.

Modello di aeroporto

C 3.2.13: Modello interno

Interior models allow viewers to understand room layouts, circulation, furniture, finishes and spatial relationships that may be difficult to judge from plans or renderings alone. Larger scales are normally used when interior details are important. RJ Models produced a 1:40 clubhouse interior model in Mumbai, measuring 2000 × 1600 × 800 mm. The model included detailed recreational spaces, lighting and a lift-up function that allowed viewers to inspect the interior arrangement of different floors.

Modello interno

C 3.2.14: Modello del paesaggio

Landscape models place greater emphasis on terrain, vegetation, water features, paths and outdoor spaces than on architectural detail. They can help designers and clients evaluate how buildings interact with the natural and designed environment. RJ Models produced a 1:100 residential landscape model in Dubai, measuring 2400 × 2200 mm, featuring waterfalls, infinity pools, artificial lakes, rockwork and extensive vegetation to communicate the project’s tropical landscape concept.

C 4.1: How Professional Model Makers Choose Materials

Architectural models rarely rely on a single material. Material selection depends on the model’s purpose, scale, required level of detail, surface finish, lighting, durability, handling and transportation requirements. Professional model makers therefore combine different materials according to the role each component must perform rather than selecting materials only by appearance.

C 5.1: Scelta delle scale dei modelli architettonici

È possibile riconoscere nei modelli in scala una necessità per la professione architettonica.

Esistono molte scale diverse di modelli architettonici.

In genere, un modello architettonico fisico è solitamente ridotto in scala rispetto alle dimensioni effettive dell'edificio.

Choosing the right architectural model scale is not simply a matter of making the model fit on a table. Scale determines the physical size of the model, the amount of detail that can be represented, how viewers experience it, and how easily the finished model can be transported and installed.

The appropriate scale should therefore be selected according to the model’s purpose, the real dimensions of the project, the required level of detail, viewing distance, display space, delivery route, budget and deadline. A larger scale can show more detail, while a smaller scale is usually more suitable for presenting large sites, master plans and urban relationships.

How Architectural Model Scale Is Calculated

Model dimension = Real dimension ÷ Scale denominator

For example, a 100 m building would be represented at approximately 1 m at 1:100, 500 mm at 1:200 and 200 mm at 1:500.

Note: 1:50 is a larger scale than 1:500. A larger scale uses a smaller denominator and allows more physical space for visible detail.

How Scale Changes What the Model Can Show

Scale Range	Typical Purpose	Information Priority
1:10–1:50	Interior, façade and detail models	Materials, furniture, components and fine architectural detail
1:50–1:200	Building presentation	Façades, openings, building form and landscape
1:200–1:500	Development and site models	Building relationships, roads, podiums and site context
1:500–1:1000	Master plans and large sites	Massing, infrastructure, landscape and development zones
1:1000+	City and regional models	Urban relationships, planning structure and major landmarks

Scale, Model Size and Transport

Scale also affects how an architectural model can be packed, transported and installed, but the scale ratio alone does not determine the logistics. The finished model dimensions are often more important. Historical RJ Models commercial records include a 1:250 model approximately 2.8 × 5 m specified for air-freight delivery to Istanbul; a 1:300 model measuring 1750 × 730 × 680 mm with delivery by two model makers and installation in Dubai; and a 1:500 master plan model measuring 1600 × 1280 × 930 mm with two technicians together with flight and excess-baggage arrangements. These examples show why logistics should be reviewed before the final scale and model footprint are fixed.

For large models, packing dimensions, modular construction, transport method and installation requirements should be reviewed before production begins.

C 5.2: Scalabilità guidata dallo scopo

In genere è possibile realizzare modelli architettonici a seconda delle esigenze di rappresentazione.

In altre parole, lo scopo principale della scelta della scala giusta è quello di rendere il modello il più convincente possibile.

I clienti devono chiarire la fase del progetto per la quale è necessaria la rappresentanza.

Per la fase di progettazione si consiglia di studiare modelli architettonici.

Working models are useful during design development, while presentation models are more suitable for the final design stage.

C 5.3: Considerazione delle condizioni e dei costi del modello architettonico

C 5.3.1: Esperienza visiva

Innanzitutto, un altro aspetto importante da considerare è il luogo in cui verranno presentati i modelli architettonici.

Assicuratevi che i modelli abbiano uno spazio adeguato per essere visti durante le mostre, evitando però un'esposizione eccessivamente scarsa.

C 5.3.2: Trasporti

In alcuni casi è necessario spostare frequentemente i modelli architettonici da un luogo all'altro.

La scala e il peso dei modelli sono quindi particolarmente importanti.

I modelli architettonici per il marketing dovrebbero adattarsi bene a una suite di marketing.

C 5.3.3: Bilancio e scadenza

Budget and deadlines are important when selecting a scale because highly detailed models generally require more production time and cost.

C 5.4: Selezione della scala e delle dimensioni

La scala determina il livello di dettaglio che può essere presentato.

I modelli architettonici su larga scala presentano un livello di dettaglio molto visibile.

Più piccolo è il numero dell'indicatore di scala, più grande è il modello e ciò significa che è possibile illustrare più dettagli.

Inoltre, molti elementi scenografici sono pre-prodotti dalle fabbriche industriali.

Utilizzo di elementi scenografici pre-prodotti

Pertanto, è opportuno valutare se la scala selezionata corrisponderà alle scale standard utilizzate nel settore del modellismo.

C 5.5: Common Architectural Model Scale Ranges

1:10–1:50 — Detail, Interior and Façade Models

At these larger scales, individual architectural components can be represented with greater clarity. They are suitable when the viewer needs to understand façade materials, windows, doors, furniture, interior finishes or construction details. The available level of detail still depends on the model’s purpose and physical size rather than scale alone.

Modelli interni

Interior models are generally produced at larger scales when room layout, furniture, finishes and spatial relationships need to be clearly understood. Scales around 1:5 to 1:25 can provide enough physical space to represent detailed furniture, fixtures, materials and interior features, while smaller scales may be used when the primary purpose is to communicate the overall layout rather than individual finishes.

The appropriate scale should depend on what the viewer needs to understand. A sales presentation may require realistic furniture and lighting, while a design-review model may focus more on circulation, room relationships and removable walls or roofs.

For projects where the arrangement of an entire floor is more important than detailed finishes, layout models at approximately 1:50 to 1:100 can provide a clearer overview of room organisation and circulation.

1:50–1:200 — Building, Section and Presentation Models

These scales are commonly suitable for individual buildings where architectural form, façades, openings, landscape and selected interior elements need to remain visible. Section models can also use this range when the purpose is to explain internal spatial relationships, floor levels or structural organisation.

1:200–1:500 — Development and Site Models

At these scales, the emphasis begins to shift from individual components to the relationship between buildings and their surroundings. Roads, podiums, landscape, neighbouring buildings and overall site organisation become increasingly important, while very small façade details may need to be simplified.

1:500–1:1000 — Master Plan and Large-Site Models

These scales are suitable when the model needs to communicate a large development, campus or master plan within a manageable physical footprint. Building massing, roads, infrastructure, landscape and development zones normally take priority over detailed architectural components.

1:1000 and Smaller — City and Regional Models

For city-scale or very large planning models, the primary purpose is usually to show urban relationships rather than individual building details. Major landmarks, road networks, development areas, terrain and planning structure can remain identifiable, while smaller buildings may be simplified into massing forms.

These ranges are practical starting points rather than fixed rules. The final scale should be selected only after considering the project dimensions, information to be communicated, display space, transport requirements, budget and programme.

C 5.6: How to Make the Final Scale Decision

The right architectural model scale should be selected by working backward from what the model needs to communicate. Start with the project’s real dimensions and presentation purpose, then determine the level of detail viewers need to see. From there, check whether the resulting model dimensions are practical for the available display space, packing, transportation and installation.

A larger scale is not automatically better. If the model becomes too large for its purpose, the additional detail may create unnecessary production, transport and display constraints. Conversely, a scale that is too small may remove information that is essential to the presentation.

The final decision is therefore a balance between purpose, detail, physical size, viewing experience, logistics, budget and deadline.
