My close friend and I bought plots of land in the Leningrad region and decided to build. I never regretted for a moment that I turned to a construction company (at my wife's insistence) instead of going to questionable builders, who constantly overcharge and use poor-quality materials, causing the house to fall apart before your eyes (as happened with my aforementioned friend). The construction company Dachnik did a great job, quickly helping us decide on the layout, choose the necessary materials, and patiently working according to our wishes. In the end, we built an excellent frame house, 6 by 6 meters, sturdy, made of good materials, and, so to speak, "for ages," all in line with our "whims." I strongly advise against looking for the cheapest options and resorting to dubious builders; instead, go with a proven company. If you're going to build, build for the long term—don't repeat my friend's mistake with his crumbling house.
