2D digital design required a different kind of knowledge than traditional blueprints. Rather than having to have an understanding of every detail of building a house, designers now needed to know how to control a computer program. These design programs are effective in ruling out man-made design errors, helping reduce the cost of correcting these errors once the house was in construction.

Once quite expensive, 2D digital design is now the most common and affordable design method. Designers now have endless supplies of house plans stored on their computers, making it virtually unnecessary for clients and designers to have to start designing a house from scratch.

2D design programs are now affordable and said to be user-friendly enough for consumers to design their own homes. Designers are still recommended because what is considered “easy” and “user-friendly” is highly subjective.
