Starting project 5.3 Flooring I found Measure. It is American flooring estimation software. It handles estimating and layout of carpet, tile, laminate and hardwood flooring for projects of all sizes. They have free 30 days trial version, that is enough to get familiar, to try it for my project and to keep it in mind in case if I need it in the future. I will do my project by hands as required, but it is good to know the easiest way to do the job :).
