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.
