A system of modular assembly comprising a plurality of structural members. Each of the plurality of structural members comprises at least two slots along a lengthwise side. A first one of the at least two slots defines a first outside slot which is located nearest to a first widthwise side and a second one of the at least two slots defines a second outside slot which is located nearest to a second widthwise side. The distance between the slot axis of the first outside slot and the first widthwise side is a predetermined slot-to-side distance, and the distance between the slot axis of the second outside slot and the second widthwise side is a whole-number multiple of the predetermined slot-to-side distance. The distance between each of the slot axes of the at least two slots along one of said lengthwise sides is a whole-number multiple of the predetermined slot-to-side distance. The plurality of structural members comprises a first vertical structural member, a second vertical structural member, a first horizontal member and a second horizontal structural member. The first outside slot of the first vertical structural member is detachably connected slot-to-slot to the first outside slot of the first horizontal structural member, the second outside slot of the first vertical structural member is detachably connected slot-to-slot to the first outside slot of the second horizontal structural member, the first outside slot of the second vertical structural member is detachably connected slot-to-slot to the second outside slot of the first horizontal structural member, and the second outside slot of the second vertical structural member is detachably connected slot-to-slot to the second outside slot of the second horizontal member such that the first vertical structural member is substantially parallel to the second vertical structural member and substantially perpendicular to the first horizontal structural member and the second horizontal structural member.
