Graduate Diploma Program in Interior Design - 1-Year Course at IDeA Worldwide

Fundamentals of Design & Drawing

This module builds the visual base every interior designer needs. You'll learn elements and principles of design, how colour works (including colour psychology), and how to create balance, contrast, and rhythm in a space. Shading and still-life composition help you understand light, depth, and texture.

You also learn one-point and two-point perspectives and composition techniques such as the rule of thirds and the golden ratio. This helps you progress from basic sketches to drawing clear perspective views of rooms and interiors.

You will learn to:

• Apply design principles to create balanced interiors

• Use colour theory to build mood and style

• Draw perspective views for space understanding

• Improve presentation through shading and composition

Materials, Construction & Building Elements

Interiors are not just about looks, materials decide durability, comfort, and maintenance. In this module, you study timber, stone, bricks, partitions, wall panelling, metals and alloys, and materials like glass and plastics. You also learn how building elements work together, including parts of a building that influence interior decisions.

The focus is on practical understanding: where each material fits best, its pros and cons, how it behaves over time, and how it affects cost and design.

Key material decisions you'll handle:

• Choosing materials based on durability and maintenance

• Matching finishes to style and budget

• Balancing cost, performance, and aesthetics

Space Planning, Anthropometry & Interior Concepts

This module teaches you how to plan spaces for real people, not just for drawings. You learn anthropometry (human dimensions), movement flow, and zoning so layouts feel comfortable and functional. Furniture history adds context to styling and design language.

You'll also learn basic Vaastu guidelines as an informative layout reference (practical, not superstitious), along with landscape and decorative design concepts. Doors and windows typologies help you understand how openings influence space planning and light.

By the end of this module, students can:

• Plan living rooms, bedrooms, kitchens, and office layouts

• Create better movement flow and functional zoning

• Apply ergonomic planning using human dimensions

• Consider context factors like views, openings, and layout logic

Lighting, Ceilings, Finishes & Furnishings

Lighting and finishes are what make a space feel complete. This block teaches how to build mood and comfort using lighting, false ceiling concepts, colour, textures, and fabric choices. You'll understand how to coordinate finishes for different styles, minimal, luxury, modern, and different budgets.

You also learn how each finish affects maintenance and cost, so your design choices stay realistic.

Key finish categories covered

• Flooring: tiles, wood, stone---what works where and why

• Wall finishes: paint, textures, wallpapers---style and durability

• Upholstery: comfort, cleaning, and texture coordination

• Soft furnishings: curtains, cushions---adding warmth and balance

• Ceilings & lights: ambience, placement, and visual impact

Graphics, Projects & Portfolio

This is where your learning becomes portfolio-ready work. Students complete two major projects and create presentation drawings and graphics that reflect professional interior design outputs. You learn how to take a concept and turn it into a complete project set, including plans, elevations, perspectives, mood boards, and material boards.

Projects you complete:

• Project 1: Office Design -- layout planning, zoning, lighting and presentation

• Project 2: Residence Design -- room-wise planning, finishes, furniture and styling

These projects become the core of your portfolio, important for internships, interviews, and freelance work.

Interior Design Software & Visualization

Software skills are a big part of today's interior design industry. This module trains you on AutoCAD, SketchUp, Photoshop, render engines, and 3DS Max so you can produce professional drawings and visuals.

You learn to draft accurate 2D plans, build 3D models, apply materials and lighting, and create realistic renders that help clients approve designs faster. Photoshop supports mood boards, presentations, and clean final outputs.

Digital outputs you create:

• 2D plans and drawings in AutoCAD

• 3D models in SketchUp / 3DS Max

• Rendered views and walkthrough-style images

• Presentation boards, mood boards, and material boards
