What material is cheaper to build a house?

Before starting the construction of the house, anyone wonders about the material that is more profitable and cheaper to use to build its future "fortress." Basically, the people, in the old manner, builds a brick house for themselves, considering them the most reliable, but the construction of such a house, today, is one of the most expensive!
Scientific progress does not stand still and today the modern building materials market offers a wide selection of raw materials to build houses that are significantly cheaper than standard bricks!
So:
1. Foam concrete - It is convenient to operate, moisture-proof and most importantly inexpensive. When building this material, the insulation of the walls is not required. Construction of foam concrete occurs much faster, but without the outer decoration of the walls can not do.
2. Wood. The house from a wooden bar will cost very expensive, but there is an inexpensive alternative - it is a frame-boiled wooden houses. Externally, such a structure will be almost impossible to distinguish from homes from a solid bar. The advantage of construction from the proposed material is its fast assembly - month, and maybe less. But there is a danger of poor-quality "stuffing" panels, at best, the house can become prey for Misha and insects, in the worst - to be fire hazardous. The purchase of panels for the frame-shield house must be made only at well-known and proven manufacturers.
3. Sandwich panels. Such panels are very close in design to frame-shield, however, they are a two-sided cement-chip plate with a thickness of 5 to 10 cm., With a small gasket of foam. The resulting material is not lit, does not twice, it is not afraid of rot, insects and rodents. The cost of "square" to $ 400-500.
The choice is yours! In any case, let your new home be beautiful, durable, safe and unbreakable!
