A landscaping structure, comprising: at least two stacked modules, each module having top and bottom timbers joined at overlapping corners, a plurality of the bottom timbers being arranged in a first layer forming at least one straight-sided geometrical shape, a second layer of a plurality of the top timbers overlying the first layer with overlapping timbers at each corner of the shape, each bottom timber having two spaced parallel blind corner holes provided transversely near a first end and one blind corner hole parallel to the other two blind corner holes provided near a second end, each top timber having two spaced parallel corner holes provided transversely through the top timber near a first end and one corner hole parallel to the other two corner holes provided transversely through the top timber near a second end, the corner holes and blind corner holes being spaced so that alignment of corner holes with blind corner holes is obtained between top and bottom timbers overlapping at the corners, each timber having at least one intermediate joiner hole provided parallel to said corner hole or blind corner hole spaced from the first and second ends of the timber so that alignment of intermediate joiner holes is obtained between the overlying adjoining bottom and top timbers of stacked modules; and hardwood dowels being snugly fitted through the aligned corners and intermediate joiner holes of overlapping timbers and stacked modules so that an overlying top timber is joined to two underlying bottom timbers at each corner of a module, and an overlying bottom timber of one module is joined to an underlying top timber of another module, thereby to form a structure.
