Abstract: A universal bracket system can be used to create multiple interlocking bracket assemblies for construction of buildings, dwellings, structures and other objects. A primary planar bracket plate member has flange extensions and holes for bolts or other fasteners. Multiple supplementary bracket plate members are variations of the primary bracket plate member. A ridge bracket plate member is provided. Primary and supplementary plate members, as well as the ridge bracket plate member, can be combined in multiple interlocking configurations to create brackets for connecting structural members into many different connection joints.

Abstract: A set of novel architectural design blocks is disclosed. The design blocks may be used for education, instruction, and design purposes. Generally, the blocks contain a post member positioned in a generally upright position. Also, a beam member cooperating with the post member is provided and the beam member is positioned in a generally lateral position relative to the post member. Additionally, a rafter member cooperating with the post member and the beam member is included, with the rafter positioned in a sloping position relative to the post member. The post member comprises a 3 unit by 3 unit lateral surface area such that 9 unit members are formed therein with said center unit member being void so that 8 unit members are formed by said post member. The rafter will have in the preferred embodiment an 12 unit run by 8 unit rise.
