There is disclosed a door or wall construction which comprises vertically spaced upper and lower horizontal frame members and horizontally spaced vertical side frame members coupled with the upper and lower frame members to define a rectangular frame. A panel is joined with the lower frame member and side frame members to define a lower door portion. All of the frame members comprise elongate channels having substantially identical transverse, U-shaped cross sectional-dimensions and are oriented with open faces of the U-shaped cross sections facing inwardly, which open faces are dimensioned for embracing at least outer edge portions of the panel. A novel grill structure is also disclosed which forms an upper door portion. The grill structure comprises a plurality of vertically oriented, horizontally spaced elongate rods and a pair of elongate, U-shaped channels dimensioned for embracing and overlying the respective inwardly facing surfaces of the upper frame member and the second intermediate frame member. The channels include a plurality of spaced apart sleeves for receiving and retaining opposite end portions of the rods.
