At the beginning, when Chen Xinhe's group Friends of survival group designed the shelter, the most ideal solution proposed was to use missile silos or abandoned military air raid shelters to transform the shelter and build it into a small community.

But the plan was abandoned because of China's policy and economic problems, and everyone turned to build their own private shelters.

In the initial idea, we actually had many ideas about the design of the shelter.

Some of these ideas are very practical, such as planting greenhouse, water circulation system, air filtration and communication facilities, but some are unrealistic, but they can also play a role.

For example, it's a good idea to build a library and bring a large number of paper books into the shelter. After all, paper books can last longer than electronic products. When reading, as long as you cherish books, a book can be read for decades.

Of course, this is a very practical idea, but it's a pity that before the disaster, with the development of the Internet, people rarely read physical books. Even the bookstores that used to be all over the streets have disappeared for many years, and it's very difficult to buy physical books.

In addition, everyone brought electronic products into the shelter, so the library was not so necessary. So when Chen Xin built the shelter, he left out the library.

When they first referred to the design of some foreign refuges, they saw other people's refuges, such as cinemas, supermarkets and swimming pools. In fact, they had some ideas in mind.

It's just limited by the actual situation, because it's not the community model originally envisaged, so the supermarket is useless directly, and the cinema can prepare its own home theater in the living room, which is just fine.

As for the large area of the swimming pool, it also consumes precious water resources. If the weather is too cold, we have to prepare a constant temperature equipment for the swimming pool. It's too luxurious and troublesome. It's better to prepare a big bathtub. No one really builds a swimming pool.

In addition, there are bars only owned by Mo Qingyan's family, billiards rooms of some group friends who used to like playing billiards in the urban area, and VR experience rooms of group friends who used to play VR. These functional facilities belong to only one or two talents, which are also yearning but not available to others.

Although Chen Xin later provided himself with functional facilities such as fish ponds and medical rooms through material exchange, he still did not have some things.

Now, however, Chen Xin feels that he can build some facilities to improve his quality of life, so that he can lead a better life and a more comfortable life.

For example, the frozen wine in Mo Qingyan's cellar, Chen Xin was discussing with Mo Qingyan when to get the wine out.

If he can get that batch of wine, Chen Xin thinks he can build a wine cellar and bar in the shelter.

Moreover, although he built a hot spring bath, he didn't think it was any good to use it alone before. Now that there are more people in the shelter, Chen Xin still feels that it is necessary to expand it. At least, men and women should be separated. It's not necessary to say that every time he wants to use the bath, he has to divide the time between men and women.

In addition, since it is necessary to carry out research and manufacture things, Chen Xin feels that the original workplace is a little smaller and should be adjusted.

With the emergence of Chen Xin's many ideas, the refuge on the drawing has become quite different.

Not only a few more spaces have been created, but the overall floor area is even larger. Not to mention, the main part of the shelter, which was originally buried underground and had a drop of tens of meters from the entrance, has also been adjusted on the drawings. The drop between the two is now only one floor high.

This height difference is not a problem in terms of building structure and protection performance. Originally, Chen Xin buried the main body of the refuge so deep, mainly to cope with the meteorite impact and subsequent disasters.

Now that the disaster is over, there is no need to live underground.

As for the water, electricity, heating and air filtration facilities, Chen Xin separated them from the main part of the building and set up a separate space to place them. In this way, these facilities no longer need to be placed in the main area of the refuge, and any problems will not affect the residents in the refuge.

After some adjustments, it can be said that the overall planning of the refuge is more clearly differentiated, and several new production and living facilities are added, with more perfect functions.

However, looking at the somewhat messy layout of the refuge, Chen Xin thinks that it should be adjusted.

Although we don't have to worry about the difficulty of construction and the lack of space, we should make the planning of the whole refuge more reasonable.

Thinking of this, Chen Xin remembers a video he saw before about the federal rich transforming the shelter with abandoned missile silos. The shelter transformed from the missile silos in it is really good. Both the comfort level and the function perfection are very satisfactory, and the design is also very reasonable.

So after thinking about it, Chen Xin decided to readjust the layout of his refuge.

First of all, there is no need to lay out the newly added functional areas of the refuge, which can be stacked completely. The whole refuge is designed as a multi-storey structure, which can be up and down through elevators and stairs. In this way, the layout of the building can become compact and more convenient and practical.After all, in the shelter, going up and down stairs and turning around a few corridors are totally different experiences.

Moreover, Chen Xin also plans to adjust the current four square shelter structure into a circular shape, following the example of a shelter transformed from a missile silo.

This is not to say that Chen Xin is copying or imitating, but because the circle is relatively more efficient in space utilization and can be more convenient for layout.

Of course, there is another point that the structural strength of the circular structure is stronger, and it saves more materials. Of course, Chen xinlai doesn't care about this.

Therefore, after some adjustments, the whole refuge has become a multi-storey cylindrical structure, which is still connected to the entrance of the refuge through the corridor, but it no longer needs to go down dozens of meters through the elevator to enter the interior of the refuge.

Instead, it can reach the first floor of the main part of the refuge directly, and then go down to the lower floor through the elevator or stairs in the center of the circular structure.

As for the main part of the refuge, Chen Xin separated the living room, kitchen and hot spring bathroom, which were originally connected with the bedroom. They were separately placed on other floors, and the bedrooms were concentrated on the first floor to increase the living area.

After this adjustment, everyone can have a single room and a more comfortable bed, no longer need to sleep in high and low beds.
