The first human buildings and residential shelter already in ancient prehistoric times was treated not only by the roofing, so important to protect against rain, snow, wind and other manifestations of the weather. A natural part of the shelter was also the space under the roof, after which the fire was being divided, where they slept, cooked, and many other everyday activities.
How it went
First only a place, deprived of plants, stones and dirt, later already a specially formed area of dirt, sometimes sanded. Just a floor. Then came the stone buildings, and also the ground floor was lined with stones, paving, later planks, much later concrete, parquet, linoleum, PVC and finally DECs, and today finally modern floating floors. Durable, quality, handsome, practical.
