Today around the world there is a trend in the construction of mostly spherical and more rounded forms of houses. This is due to the fact that in distant times, our ancestors identified various round forms with divine creatures. For this reason, it was round and spherical forms that became the most favorable design, which was fraught with positive energy. Throughout the time, how many people are familiar with architecture, he used spherical forms in his buildings: minaretes, churches and mosque. Nowadays, builders of many prestigious and famous companies are ready to offer a completely new building building, which deserves special attention of a potential consumer. Of course, this technology is not so new, but rather a well -forgotten old. The construction of “round” buildings originated in ancient times, when the first groups of people lived in a rounded -form dwellings. These are houses such as yurts, plague, wigwams or tents. These dwellings had a close connection with nature and were inextricable with it. If you have never encountered spherical buildings, it may seem that the structure always has small sizes. In fact, despite the external visual compactness, such houses are quite spacious inside, and on average they have an area of 50 square meters. The movers who are engaged in the drift and delivery of furniture are always perplexed how many things can place such a spherical house inside. In Western countries, the construction of a dome is widely practiced, the diameter of which is about 8 meters, and the walls are expelled to four meters. Such sizes are optimal and make it possible to realize absolutely any layout inside the house. You can give free rein to your fantasy and implement the most daring design projects in full. Spherical houses have the possibility of completing the second floor, and directly under one arch. The most important unique direction in the construction of “round” houses is that the walls are being erected exclusively from foam. The material is selected by the highest density. Such houses received their extraordinary name – “Houses of the 21st century”. Unlike metal or wood, the polystyrene does not neighing over time, it will not rot, it will not attract insects in a colony. Foam has high thermal insulation properties, and this will largely help reduce heating costs in the cold season.
