Hi Andy,

Ask the laywer for a copy of the nota simple (he must have one if he handled the previous sale). In the nota simple you will find a description of the buildings.

If he had the buildings legalized in 2003 there is not only made a certificate by an architect, but also a new escritura with the "declaration de obra nueva" to register the buildings in the registro de la propiedad. In this document there also is a description of the buildings.

Hope this helps,
Mark
