To solve the problems that a natural solid wood needs to be chemically treated using a resin or by acetylation in order to deal with a hygroscopic action and unless this treatment is performed, cracking, warpage, contraction and the like occur due to a change in the moisture content of the wood, and that many working and treatment steps for holding for wiring and embossing of the conventional processing method need to be simplified.

The cracking, warpage, contraction and the like of the natural solid wood as qualitative defects are prevented from occurring to the maximum possible extent with the adoption of drying technique and assembling technique such a cutting or bonding of the woody material. In addition, the role of the hollow arrayed pillar wall adopting the air layer introduced into the assembled pillar to be played in a residential architecture, is diversified and the effect of the role is considered significant. Further, since a residence adopting the hollow arrayed pillar wall necessarily uses a larger quantity of woods, compared with the residence built using a conventional technique, the indoor living environments are upgraded with the addition of acoustic/ sound insulating properties, heat insulating properties and moisture-conditioning performance. Besides, the building period using said pillar wall can be widely cut, compared with the conventional building period.
