A latticework structure (26) providing a composite curved appearance is formed from slat elements (25) each having a shape defined by a waveform curve repeating about a longitudinal axis (35), the waveform defined by a wavelength (D5) and a magnitude (D6), each of the first slat elements having a substantially constant and common width (W) orthogonal to the defining curve. Such elements are arranged into two levels with axes of symmetry of the slat elements are parallel, and the width (W) of the slat elements (25) in one level at maxima points positioned to overlap the width of minima points of the slat elements on the other level (67), and the elements are joined at the areas of overlap (59, 61, 63). In a preferred embodiment, the elements (25) are wooden slats, and in other embodiments other materials are used, such as plastic and metal. Joining methods are selected appropriate to the materials used. In an alternative embodiment, the slat elements (100, 101) on one level are parallel in one direction, and in the other level slat elements (103, 105) are parallel in a crossing direction to the direction of the axes of the first slat elements, providing a structure of increased strength exhibiting increased economy of manufacture. In both side-by-side and in crossing patterns, panels are provided with notches (113, 117) at the overlapping areas, producing panels with the thickness of a single slat element.
