If you are someone who has just decided to start a home-based interior design business and wonders if hand rendering is something you need to learn, then this is a good place to catch up with information.

What Interior Hand Rendering does?

An interior design drawing’s goal is to show a concept or representation of an interior with a new layout of a new or existing space with its design details.

The interior design hand rendering shows the placement of furniture, fixtures, appliances, décor, and other design elements. The colors and textures are also presented in a hand rendering interior design. In-house hand sketches are often used in combination with other computer drawing-rendering methods.

 

“Hand rendering is one of the first known techniques used by interior designers and architects to visualize spaces in three dimensions. One of the positives of hand rendering is the credibility and authority perceived by the client. Hand rendering sketch or demonstrating at client’s  meeting always looks impressive.”

George Nicola (Expert Stager)

Interior Design Hand Rendering Techniques a must have?

Interior Design hand rendering is a must-have if you are an interior designer. Even though computer-generated renderings have become the standard platform for delivering 3D simulated built environments, nothing beats the value of a hand-drawn rendering in addition to the spectacle and impression that are left with the client.

 A display of authentic art and technique is highly advantageous for a visual artist to start with the basics of hand rendering before diving into digital techniques.

This enables renderers to conceptualize ideas faster and have a useful skill on hand whenever computer generation fails to deliver.

In-house hand sketches are used often used in combination with other computer drawing-rendering methods in client meetings for quick annotation and further detail translation.

It takes creativity and skill to produce a working interior design hand rendering, and with this, designers can satisfy and express their artistic skills.

In a practical sense, interior sketching is still needed as a basic tool for presenting on-the-spot conceptualization to clients.

However, dedicating to hand renderings for clients nor with computer-aided designs solely is not a practical choice.

Thus, knowing both worlds is a must-have as it brings designers flexibility and freedom in their presentations.

In interior design hand drawing, there are a number of techniques and mediums that can be used. 

Interior design hand techniques

# Monochromatic Renderings

For monochromatic renderings usually black or one color is used for the entire image. Light and shadow are the main concerns when it comes to your monochromatic representations.

Suggested Tools to be used for monochromatic renders include:

# Hatching

For freehand renderings the basic rendering strokes include:

Tones are created by a series of tightly spaced parallel lines of regular or irregular marks in an area. The primary notion is that the number, thickness, and spacing of the lines alter the overall image’s tonal values, emphasizing shapes rather than just the shape.

# Crosshatching

For crosshatching renderings the basic rendering strokes include:

 

Layers of parallel linear lines overlapping or changing directions are drawn.

They can be drawn vertically, horizontally, or at an angle diagonally.

# Scribbling

For scribbling renderings the basic rendering strokes include:

 

The most prevalent sort of scribbling is circular scribbling.

Filling in a drawing with scribbles is a quick and easy way to do it.

Due to its quickness and lack of detail, this style is most typically seen in sketches.

# Stippling

For stippling renderings the basic rendering strokes include:

 

Dubbed as the “dot matrix”, it’s a shading technique in which dots are used to shade an area. The darker it seems, the closer the dots are and the more populated an area of the image is.

This method takes the longest and looks best from afar.

Hand Rendering Technique vs. 3D Interior Technique

How do you find if your hand-drawn sketches (assuming you’re good at them) or interior 3D renderings are the right choices for your one-person army interior design team?

Both are unquestionably significant and can set up entirely different courses for your interior practice if used well. 

Both hand-drawn sketches and 3D renders should be presented to the client. Each of them, however, should be given at distinct stages of the project.

Hold on for a bit!
We’ve published a very interesting guide in Developing an interior design team; go check it once you reach the bottom of this text.

Colored Hand Rendering

Freehand rendering in color for interior design utilizes the 4 basic strokes for rendering using colored ink and pencil. Still, there is a wide range of rendering techniques depending on your medium.

The most common is the use of watercolor, oil paint, colored pencil, magic marker, and water-ink. You can combine two or three of these mediums except for oil paint. To make it even easier to compare, we’ve put a number after each method with the average number of designers using it to make this easy.

# Water Color

colored hand rendering

A medium that needs fast delicate strokes and creates an almost translucent quality to an image. The basic techniques include wet-on-dry, dry-on-dry, dry-on-wet, flat wash, and gradated wash.

2 out of 10 designers use this approach on average today.

# Magic Marker

Unlike water and oil-based mediums, the magic marker is a convenient medium without the need for the intricate process of preparing colors. Therefore, this medium is a practical choice for quick illustrations as well as for full renderings.

5 out of 10 designers use this approach on average today.

# Oil Paint

The oil-based paint is a medium that can create impactful renderings with its full-color and opaque quality

1 out of 10 designers use this approach on average today.

# Colored Pencil

Similar to your magic marker, the colored pencil is a convenient medium to create quick but visually impactful hand renderings with color.

1 out of 10 designers use this approach on average today.

# Water-Ink

The Water-ink technique is a very well-known rendering method but not widely used by designers due to its messy nature.  The renderings comes out with pleasant colors to the eye.

1 out of 10 designers use this approach on average today.

Hybrid model 3D + Software

When it comes to the sections and elevations of interior renderings, things sit very differently. The nature of these sketches is to demonstrate technical constraints and relation to their immediate environment and how they link to each other.

Because of how well the 3D rendering software got developed over the years, elevation hand-renderings are quicker to produce with almost similar results.

 

We’ve written a really good article about Why Interior designers pick CGI as a method for rendering?

Conclusion: What is Interior Design Hand Rendering?

When it comes to deciding whether to go freehand or computer-generated renderings, it boils only to the end-user. Thus, knowing both skillsets is advantageous and offers more flexibility for both the client and the designer.

So, if a client needs an on-the-spot rendering of your vision, you can easily sketch as you explain in real-time while having a 3D simulation that provides more project perspectives which are useful during final presentations.

VIRTUAL STAGING EXPERT / After eight years+ working in high-end design and property business I realised that we are missing a critical part of the property business. We were not providing enough value to these old and empty properties. Not every buyer would have the opportunity to see the potential of vacant property or in a bad state. The idea of Virtual Furniture Staging the property gives the buyer and seller an incredible chance in seconds of taking the critical decision.
