Carlo and Danna bought a prime lot in Ayala Alabang Village, Muntinlupa, where they decided to have a house built for the family they were going to raise. A big fence was temporarily built around the property to avoid the construction from getting interrupted and to prevent neighbors and outsiders from taking pictures of its progress. The construction of the 3-storey house commenced and was completed in 6 months. When the fence was about to be replaced by permanent gates, the village association officials of Ayala Alabang Village saw the 3-storey house for the first time. They immediately presented the Ayala Alabang Village rules to Carlo and Danna which limited the size or height of the residences to 2 stories. In this situation, what are the obligations of Carlo and Danna?
