Interior design professionals in Kenya rely heavily on physical models to communicate spatial ideas, experiment with design concepts, and present proposals to clients and stakeholders. Model making transforms two-dimensional plans into tangible, scaled representations that provide deeper insight into residential space layouts and finishes. This chapter focuses on producing different types of models, beginning with residential space model making, a core skill for interior designers working on homes, apartments, and other dwelling units across Kenya’s diverse housing market.

2.1 Residential Space Model Making

Residential space models are essential tools in interior design to visualize and evaluate the arrangement of rooms, furniture, and finishes within a home. In Kenya, where clients often require detailed presentations to understand design proposals, physical models bridge the gap between abstract plans and lived experience. These models assist in decision-making about space utilization, lighting, and aesthetics before costly implementation begins.

2.1.1 Purpose and Importance of Residential Space Models

The purpose of residential space models extends beyond simple visualization; they serve as interactive tools for both designers and clients.

Purpose of Residential Space Models

• Visualization of spatial arrangement: Models provide a three-dimensional perspective that helps clients and designers grasp the layout of rooms and circulation paths more clearly than flat drawings.
• Design communication: They facilitate clearer communication of design intent to clients, contractors, and suppliers, minimizing misunderstandings during project execution.
• Evaluation of design alternatives: Physical models allow designers to test different layouts, furniture placements, and finishes, identifying practical and aesthetic issues early.
• Client engagement: Interactive models enable clients to engage with the design, providing feedback that can be incorporated before finalizing plans.
• Budget control: By reviewing a tangible model, clients can make informed decisions about costly elements, helping to manage project budgets effectively.

Importance of Residential Space Models in the Kenyan Context

• Cultural relevance: Models help integrate traditional Kenyan spatial concepts, such as courtyards or multi-generational living spaces, ensuring designs reflect local lifestyles.
• Client diversity: With a range of clients from urban middle-class families to rural homeowners, models tailor communication to varied levels of technical understanding.
• Project approval: County governments and housing authorities often require detailed presentations, where models enhance the credibility of design submissions.
• Material selection: Models assist in showcasing locally available materials and finishes, which influence cost and sustainability.
• Training and education: Interior design students and apprentices in Nairobi and other regions use model making as a practical learning tool for spatial reasoning.

2.1.2 Types of Residential Space Models

Residential space models vary depending on the stage of design and the level of detail required. Understanding these types helps interior designers select the appropriate model for each project phase.

Conceptual Models

• These are quick, simple models made early in the design process to explore general spatial relationships and massing.
• They are often constructed from inexpensive materials such as cardboard or foam board.
• Conceptual models focus on form and flow rather than detailed finishes.
• They help clients visualize the overall layout before committing to detailed plans.
• In Kenyan residential projects, conceptual models may incorporate local architectural features like verandas or traditional roofing styles.

Presentation Models

• Presentation models are highly detailed and refined, intended for client approval or stakeholder presentations.
• They feature scaled furniture, textures, and color schemes to simulate the finished space realistically.
• Materials such as basswood, acrylic, or 3D printed components may be used for precision.
• These models demonstrate lighting effects and furniture arrangements vividly.
• For developments like gated communities in Nairobi, presentation models help market properties by showing prospective buyers the interior layout.

Working Models

• Working models are functional tools used during the design development phase.
• They allow designers to test and modify spatial arrangements, furniture layouts, and circulation.
• These models are durable and easy to alter, often using modular components.
• They assist in coordinating with contractors and suppliers for measurements and specifications.
• In Kenyan residential construction, working models can help address challenges like limited space in urban apartments by experimenting with multifunctional furniture.

Scale Models

• Scale models represent the residential space at a reduced scale, typically 1:50 or 1:100.
• They maintain accurate proportions to allow precise spatial analysis.
• These models can be either conceptual or presentation types, depending on detail.
• Scale models are essential for integrating interior design with architectural plans.
• For example, a scale model of a townhouse in Mombasa can help visualize airflow and natural lighting.

2.1.3 Materials and Tools for Residential Space Model Making

Choosing the right materials and tools is crucial for producing effective residential models that are both accurate and visually appealing.

• Foam board is preferred for walls and large surfaces due to its stability and ease of cutting.
• Cardboard is cost-effective and ideal for early-stage models where rapid changes are expected.
• Basswood enables fine detail work, such as creating miniature furniture or intricate moldings.
• Acrylic sheets simulate glass elements, essential for realistic window and door representations.
• Precision tools like craft knives and cutting mats ensure clean edges and professional finishes.

2.1.4 Steps to Produce a Residential Space Model

Producing a residential space model requires careful planning and execution to ensure accuracy and clarity.

1. Review design plans and measurements: Gather all architectural drawings, furniture layouts, and specifications to establish scale and dimensions.
2. Select appropriate scale: Choose a scale that balances model size with detail visibility, commonly 1:50 for residential interiors.
3. Prepare base and walls: Cut foam board or cardboard to represent floors and walls, ensuring precise dimensions according to scale.
4. Assemble structural components: Use glue and pins to fix walls to the base, maintaining perpendicular angles and alignment.
5. Add interior elements: Construct and position furniture, cabinetry, and fixtures using basswood or cardboard, paying attention to spatial relationships.
6. Incorporate finishes and textures: Apply paint, fabric swatches, or printed materials to surfaces to simulate real finishes.
7. Detail openings and lighting: Use acrylic sheets for windows and add miniature light fixtures, if applicable, to enhance realism.
8. Review and adjust: Inspect the model for accuracy, making modifications to improve clarity or correct errors.
9. Present model: Use the model as a visual aid during client meetings or project reviews, inviting feedback.
