Additive Forms

Architects can develop complex structures by combining forms — this is known as creating space by addition, or “additive forms.” Forms can be added in many ways, from edge-to-edge contact to interlocking relationships. The additive approach can be regular — forms arranged sequentially in a row — or irregular, with clustered forms.

The additive approach to space often works from the inside out and creates structures that might seem irregular but can cope with changes in internal function easily.
 

Click 1, 2, 3, or 4 on the left to view examples of buildings constructed with additive forms. Click the "2D Exercise" or "3D Exercise" tabs to create your own additive forms. To do so, add forms by clicking on the desired shape's thumbnail, and then rotate, scale, or move the forms using the transformation tools.
