Before, before we had market relations in the economy, construction was much easier. Presented several drawings, they were approved and you can start building an object. Layouts were used rarely, and even then exclusively by the architects-designers who wanted to see how their design will look outwardly.

Now the production of mock-ups became a necessity. Why? It's all about investing. After all, no matter how wonderful the project of the most beautiful building or a beautifully planned park, without getting money, construction can not begin. And to do this, you need an investor who agrees to invest their own money in the business so that, after making a profit.

The layman does not understand anything in the drawings (even the most detailed ones). Investors, in principle, do not particularly care about the drawings (they will be checked by hired people separately), but how it looks like a new house looks very much even worries. And here architectural models allow you to look at the whole object from the side. This is a kind of advertising project and the better and more detailed it is, the better the advertisement. This means that the chances of getting an investment are much higher.
