A building wall construction installed on a building comprises a plurality of successive window units and at least one corner window unit disposed between two adjacent ones of the window units and having a preformed corner angle identical to that of a corner of the building where the corner window unit is positioned. The corner window unit is joined to the adjacent window units by attachment projections positionally adjustably fitted in recesses, respectively. The corner window unit may be of a salient or re-entrant corner angle. |
