PROBLEM TO BE SOLVED: To easily improve an ALC external wall by securing a reinforcing furring strip to the surface of the existing ALC external wall and fixing a new dry type wall material to the reinforcing furring strip to reinforce the ALC external wall. SOLUTION: In an existing wall surface in which a horizontal material B and an ALC external wall C are secured successively to a vertical material A forming a frame of a building, a reinforcing furring strip D comprising a belt-shaped flat plate is placed on the surface of the wall C in parallel with the vertical material A and a fastenerαis driven into the horizontal material B to fix the strip D. And a dry type wall material E, as an external facing material, comprising a siding material, in which the opposite sides of a core material are covered with a thin metal plate, a synthetic resin plate, etc., is secured to the strip D by means of the fastenerα. Belt-shaped reinforcing materials comprising a thin metal plate may be obliquely arranged on the wall C so as to intersect to one another to form braces. Further, buffer layers are stacked on the underside of the strip D to absorb the irregularity of the wall C. Thus a new external facing material can be provided by reinforcing an existing ALC external wall.
