The main principle of repair in an apartment or house is a design project or interior design. Start repairs in an apartment without a project is very risky, unworthy and unreasonable. And the quick execution of the project is in doubt about the skill and literacy of a construction company or construction team. Judge for yourself whether excellent specialists will begin to start work in their business without a clear and approved action plan, which is provided by the customer? Obviously, no. And start repairs without a approved project is a case of non -professional.
