Professional Interior Design Process for Various Styles

To create outstanding interior designs, the architects at HAC SAN work professionally and passionately. The professional interior design process includes 7 important steps as follows, depending on the design style:

Step 1: Receiving Customer Requests

We begin by receiving information and requests from our customers, including the type of project (townhouse, apartment, villa, restaurant, showroom, etc.), size, preferred design style, intended use, investment budget, and other specific factors. This helps us understand the customer’s needs.

Pricing for Interior Design Services

Step 2: Site Survey

Our design team conducts a detailed survey of the project. We measure floor dimensions, inspect door systems, take photos, and note concrete columns, and other details to understand the current state of the project.

Step 3: Contract Signing

After discussing and negotiating with the customer regarding design elements, we signed a contract to agree on pricing, timelines, and responsibilities for both parties.

Pricing for Interior Design Services

Step 4: 2D Floor Plan Design

We proceed with the 2D floor plan design to allocate space and position interior elements within the project.

Pricing for Interior Design Services

Step 5: 3D Rendering Design

Once the 2D floor plan design is accepted, we create 3D rendering drawings to simulate the actual interior furnishings and design space.

Step 6: Design Presentation

We present a detailed design proposal to the customer and listen to their feedback, making adjustments and revisions as necessary.

Step 7: Product Handover

Finally, after completing the design documentation, we hand over the product to the customer and proceed with the interior construction. We always ensure that the final product matches the 3D design drawings, guaranteeing quality and customer satisfaction.

Note: In this process, changing interior design styles does not affect the overall workflow.

What is interior design?

According to the definition from Wikipedia Encyclopedia: “Interior design describes a group of various related projects that involve turning the interior space into effective settings for the range of human activities that are to take place there. Interior design is also a profession that combines creativity, technical knowledge, and business skills. Interior designers work with clients and other design professionals to develop safe, functional, attractive design solutions that meet the needs of the users of the space.”

In simpler terms, interior design is the arrangement and organization of objects, furniture, and spaces to create a unified whole that satisfies both the functional and aesthetic needs of the users. The main goal of interior design is to create a comfortable, functional living space that reflects the owner’s unique sense of style.

Pricing for Interior Design Services

Many people often confuse interior design with interior decoration. However, these two concepts are entirely different. While interior design involves shaping the space and arranging the interior elements, interior decoration deals with the placement and adornment of smaller details within that space. Interior decoration focuses on the aesthetic aspects, while interior design must ensure both aesthetics and functional usability.

Important Elements in Interior Design

To create a perfect interior design, there are several crucial elements to consider. These elements include space, lines, shapes, lighting, color, materials, and patterns.


Space is the foundation of interior design. It’s an element that cannot be easily altered and must be utilized to its fullest potential. Space is divided into solid space and void space. Solid space is where objects and furnishings are placed, while void space is where there are fewer or no objects (often pathways). Achieving a harmonious balance between these two types of space is essential in creating a well-balanced interior space, avoiding overcrowding or emptiness due to too much or too little furniture.


Horizontal, vertical, and dynamic lines shape the form of interior spaces. Horizontal lines from surfaces like tables, chairs, and beds create a sense of stability and make the space appear more expansive. Conversely, vertical lines created by elements like windows and doorways give a feeling of height. Dynamic and curved lines, such as winding staircases, add focal points and bring positive energy to a room.


Shapes apply to both rooms and the objects within them. In interior design, objects within the same space often have similar shapes to create harmony and balance. Excessive diversity in shapes within the same space can lead to visual confusion and complexity.


Lighting is an incredibly important element in interior design, directly affecting the mood of the space’s occupants. Naturally lit spaces tend to feel cheerful and bright, whereas poorly lit spaces can create a sense of gloominess.

Lighting in interior design encompasses both natural light and artificial light (electric lighting). Balancing these two light sources is crucial in creating the perfect interior space. Natural light is typically prioritized because it brings positive energy and comfort.


Color has the power to evoke emotions and strongly influence mood. Color choices can alter perceptions of a space’s size; lighter colors like white, beige, and cream can make a space appear larger than darker colors like brown or black.

Color can also stimulate the visual senses and create various emotions. Colors like blue, green, and pastel shades can induce a sense of tranquility and softness, making them popular choices for bedrooms.


Materials are another critical element in interior design. Choosing quality materials can create a sense of sophistication and depth in a room. Each type of material and surface offers a unique feel, so material selection should be carefully considered.

Pricing for Interior Design Services


Patterns add focal points to a space. They appear on many interior furnishings such as curtains, rugs, sofas, wallpaper, and various other places. Types of patterns include horizontal stripes, vertical stripes, polka dots, and various other designs. Choosing suitable patterns can create focal points in a space without overwhelming it.

The Importance of Interior Design

Nowadays, people are paying more attention and investing more in interior design, indicating its significant importance in every construction project. Interior design plays a vital and diverse role in various types of buildings:

  • In the realm of residential properties, interior design goes beyond creating aesthetically pleasing and visually appealing living spaces. It also caters to the practical needs and preferences of homeowners. A well-designed interior not only enhances the comfort and relaxation of the occupants but also contributes positively to improving their overall quality of life. Thoughtful and scientific interior design optimizes utility and convenience in daily life.
  • For commercial projects such as shops, showrooms, entertainment venues, and restaurants, interior design serves the purpose of optimizing the use of space and creating interesting focal points. It attracts customers and establishes a unique brand identity, enhancing competitiveness and making a business stand out in the market.
  • In public buildings, offices, and workplaces, interior design must create a conducive environment for comfortable work, boost employee morale, and reflect the cultural ethos and style of the organization or business.

In summary, interior design is not just a valuable companion but also the “soul” of every construction project, playing a multifaceted role in enhancing functionality, aesthetics, and the overall experience of the space.
