From Concept to Creation

About the project

The interior design process is a structured, multi-step approach that transforms a space from an initial idea into a fully realized home. At Colossus Mfg., an interior design studio based in Encinitas, California, each phase is thoughtfully considered to ensure the final result is both beautiful and highly functional.

Below is a breakdown of the interior design process, from the first conversation to the final styling.

Step 1:

Initial Interior Design Consultation

The first step in the interior design process is the initial consultation. This is where the designer and client align on goals, lifestyle needs, budget, and overall expectations for the project.

This phase is essential. We take the time to understand how clients live in their space, what inspires them visually, and what functional challenges need to be solved. A strong foundation at this stage ensures the project is both aesthetically successful and practical long-term.

Step 2:

Concept Development and Design Direction

After the consultation, the next step is concept development. This is where the creative direction for the project takes shape.

In this phase, we develop a clear design concept that reflects the client’s personality, lifestyle, and goals for the space. This concept acts as the guiding framework for the entire project and is revisited throughout the process to ensure consistency. A strong concept ensures the design feels intentional, cohesive, and uniquely tailored to the client.

Step 3:

Space Planning and Layout Design

Once the concept is established, the focus shifts to space planning. This step determines how the room or home will function day to day.

Based on the client’s needs, we create detailed floor plans that lay out furniture, circulation paths, and key functional zones. Advanced tools and 3D modeling are often used so clients can visualize the space and understand how everything will work together before construction begins.

Step 4:

Material and Finish Selection

Material selection is one of the most impactful stages of the interior design process. This includes choosing finishes including flooring, paint, wall treatments, lighting, furniture, and textiles.


Colossus Mfg. approaches this step with great care, selecting materials that support the overall concept, reflect the desired mood, and stand up to real-world use. Materials are chosen not only for their appearance, but also for durability, comfort, and how they interact with one another.

Step 5:

Design Development and Visualization

During design development, the concept and selected materials are refined into a fully detailed design. This is where ideas become tangible.

The design gets translated into comprehensive drawings and 3D visualizations, allowing clients to see and experience the space before it’s built. This phase helps eliminate uncertainty, align expectations, and ensure every detail, layer and material feels intentional.

Step 6:

Construction and Project Management

The next phase is construction and project management. During this stage, the interior designer works closely with builders, contractors, subcontractors, fabricators and vendors to ensure the design is executed correctly.


We take a hands-on project management approach, coordinating timelines, budgets, and on-site decisions to keep projects running smoothly and efficiently. Clear communication during construction is key to delivering a successful final result.

Step 7:

Installation and Final Styling

The final step in the interior design process is installation and styling. This is when the space truly comes to life.

Furniture, lighting, artwork, textiles, and decorative elements are installed and styled to create a finished environment. This stage is treated with a seasoned eye and is an iterative process until the space feels comfortable, cohesive, and complete.

A Thoughtful Approach to Interior Design

The interior design process is about more than selecting furniture or finishes. It’s a collaborative journey that balances creativity, functionality, and execution.

By following a clear process—from consultation through installation— we create interiors that feel personal, intentional, and designed to be lived in.
