This study addresses symmetry as a compositional resource in the work of Italian architect Andrea Palladio, and aims to verify the formal, spatial and perceptual developments, caused by the use of symmetry in the domestic architecture of Palladio, represented here by the Villa Foscari (Malcontenta di Mira, 1559). Three - dimensional models are generated with the objective of verifying the transformations caused by the symmetry; these represent the geometric shape of space. As a result we evaluate the potential of three - dimensional models to represent the consequences generated by use of symmetry.
