FACTS:

Mother-in-law  offered  a  lot for  the  construction  of  house  by  the  spouses.  Here comes Sarmiento, alleging himself to be the owner of the land.  The trial court ordered Sarmiento to exercise option and there was failure to do so.  The spouses then consigned the amount in court.
 

HELD:

The  landowner  cannot  refuse  both  to  appropriate  or  sell  the  land,  and  to compel the builder to remove it from the land on which it  is  located.  He is entitled to such demolition only when after having chosen to sell the land, the other party fails to pay for the same.
