Ecologically safe constructional materials, and particularly large-sized constructional structures such as wall plates can be economically produced. Wood or another vegetable material ground to the particle size of not more than 2x10-3 m, dried to 9-11% moisture content, heated by heating the press-mold to the 200 DEG to 220 DEG C. temperature and adding ground material heated at least 120 DEG C., and loaded it into the press-mold for 1 to 1.5 min. per 1x10-3 m of produced pressed material. After that, pressing is done in a hermeticly sealed press-mold at this temperature at a pressure of not less than 30.0 MPa with exposure to this pressure for 1 to 1.5 min. per each 1x10-3 m of produced pressed material followed by cooling of press-mold without depressurization at full pressure.
