how it works

From Sketch To Life

3D Design is the process of creating digital, three-dimensional models that visually represent real or conceptual objects and spaces. In the context of interior design, it’s a tool that allows designers to transform a flat floor plan into a realistic, interactive visualization of a room or an entire building’s interior.

  • Visual Clarity – Shows clients exactly how their space will look before construction or renovation starts.

  • Cost & Time Efficiency – Prevents costly mistakes by allowing changes in the digital stage.

  • Creative Flexibility – Enables testing multiple layouts, color schemes, and furniture arrangements quickly.

  • Better Communication – Aligns the vision between designers, clients, and contractors.

The cost of interior design work depends on several factors, including the project size, scope, location, designer’s experience, and the quality of materials used. Interior design pricing usually covers two main parts: Designer’s Fees and Execution Costs.

The time you’ll spend on planning an interior design project depends on the project size, complexity, and how quickly decisions are made, but for most projects, planning takes 20%–30% of the total project timeline.

Here’s a breakdown for a typical interior design process:

1. Initial Consultation & Concept Development1 to 2 weeks.
2. Detailed Planning & Design Finalization2 to 6 weeks.
3. Procurement Planning – 1 to 2 weeks.

Absolutely — you can create a custom design for your interior, and in fact, that’s one of the biggest advantages of working with an interior designer or using 3D design tools.

Custom interior design means your space is planned and built specifically for your needs, taste, and lifestyle instead of using generic, ready-made layouts or furniture.
