Interior Design Project: How It Works, What to Include, and the Top Trends of the Year

Do you know exactly what an interior design project involves? Think of it as a journey that transforms empty spaces into environments full of personality.

This phase is a cornerstone of any building project, the point where all efforts culminate in functionality, comfort, and aesthetics.

It’s when the designer and the client collaborate to shape everything from materials and colors to furniture and lighting design.

It’s the point where the space truly comes to life,  with style and personality. But to make it all work as planned, it’s essential to understand how an interior design project unfolds.

In this article, Blocks walks you through every stage of the process, from concept to completion. Let’s take a closer look.

What Is an Interior Design Project?

Basically, an interior design project is a detailed plan for the organization and design of interior spaces.

A professional interior designer considers function, comfort, aesthetics, and ergonomics to craft environments that are both beautiful and livable.

It all starts with a deep understanding of the client’s needs and preferences, followed by a smart spatial layout that optimizes flow and usability.

A well-designed project is also adaptable, evolving with the occupants’ lifestyle and needs.

Ultimately, it should mirror the personality and lifestyle of the people who will live in and enjoy the space.

How Does an Interior Design Project Work?

So, how does an interior design project work? It typically follows a series of steps designed to make sure everything comes together smoothly. Here’s what the process looks like:

  1. Briefing: The designer meets with the client to understand their needs, preferences, and budget.
  2. Site Measurement: The space is measured and its features and limitations are assessed.
  3. Concept Development: A creative design direction is established to guide decision-making.
  4. Layout Planning: A functional layout is developed, defining spatial flow and furniture placement.
  5. Material Selection: Finishes, colors, and textures are chosen.
  6. Furniture & Accessories: Furniture, lighting, and décor items are defined.
  7. Visualizations: 3D renderings or mood boards are presented to help the client envision the final design.
  8. Budgeting: A detailed cost estimate is prepared based on the selected elements.
  9. Implementation: The project is executed with the designer supervising to ensure everything stays on track.
  10. Final Review: Once completed, the space is reviewed to guarantee quality and client satisfaction.

These are usually the main stages of how an interior design project works. But, keep in mind that these stages can vary depending on the designer, project scope, or client expectations.

What are the must-haves in an interior design project?

Now that you know how the process works, let’s look at what an interior design project should never be without:

1. Layout Plan

At the core of every successful project lies a well-developed layout plan.

It determines furniture placement and spatial organization, directly influencing how comfortable and functional a space feels.

An effective layout should ensure a natural flow of movement, free from obstructions.

It also plays a key role in establishing distinct zones  — for  work, relaxation, and socializing — ensuring each area is equipped to serve its purpose.

2. Reflected Ceiling Plan (RCP)

Next up is another key element in an interior design project: the Reflected Ceiling Plan (RCP). It lays out how the ceiling will be designed and detailed in each room.

It details the placement of lighting fixtures, decorative soffits, moldings, and other functional or aesthetic elements that  form part of the ceiling design.

A well-executed RCP enhances the lighting quality of the space and can even be used to create natural light effects.

It also serves to conceal electrical installations and HVAC systems, ensuring a clean and polished finish.

3. Lighting Design

Another essential element of an interior design project is lighting design, — because lighting has the power to completely transform a space.

With strategically placed light points, interior designers can create distinct atmospheres and highlight architectural and decorative elements within the project.

A well-planned lighting design should balance functionality, aesthetics, and energy efficiency.

That’s why it’s important to define the different types of lighting: ambient, task, and accent. Each serves a specific purpose within the space.

4. Floor Plan

Fourth on the list is the floor plan, a fundamental part of any interior design project. It serves as a visual map that guides the spatial layout and furniture placement throughout the environment.

Essentially, it’s a graphical representation of the arrangement of rooms within a building, shown as a horizontal section at approximately 1.2 meters above the floor level.

When developing a floor plan, it’s important to consider circulation, functionality, and spatial harmony. You should also define shared areas, private spaces, and service zones.

This ensures a logical and organic flow between different parts of the interior.

5. Furniture Planning

All of the previous steps are essential, but furniture planning is what gives the interior design project its final touch.

This is the stage where the space gains personality. It’s when the client can select furniture, décor, artwork, and more.

However, before selecting any items, it’s essential to understand the function of the space: this will help determine which pieces are necessary. Ask yourself: What purpose will this space serve?

Once you have a clear answer, you and your client can define the furniture and décor that will bring the space to life.

6. Landscape Design

Many people focus heavily on certain areas of an interior design project, like furniture and lighting, and end up overlooking the landscape design.

Yet landscape design plays a key role in complementing the overall interior project.

Today, it’s especially important, as more people seek a connection with nature, even in small ways.

In addition to enhancing outdoor aesthetics, landscaping also promotes biodiversity and improves the well-being of users.

7. Sections and Elevations

Seventh on the list, we can’t forget sections and elevations, essential tools for understanding the spatial layout of a project. 

Sections are vertical sectional drawings that reveal the internal distribution of the space and the relationship between different levels.

They allow designers to visualize ceiling heights, furniture placement, and even construction details like ceiling structures and soffits.

Elevations, on the other hand, are horizontal views, as if you’re looking directly at the walls.

They’re crucial for understanding the layout of each space, showing the position of doors, windows, lighting points, and electrical outlets.

Curious about what’s shaping interior design this year? Two key concepts are leading the way: minimalism and sustainability. Let’s take a closer look!

Nature-Inspired Color Palettes

Color palettes that reflect the natural environment like green, beige, and brown are taking center stage.
