Las Terrenas and its surroundings has building zones. Every zone has its specific requirements and limits. Most important is the building density, which is counted in bedrooms per hectare / ha / 10,000 m2.
Example on a 2,000 m2 lot in Playa Coson:
the building density is there 30 bedrooms per ha. 2,000 m2 is 1/5 from a ha. So the density number is 30/5=6. That means you can make a total from 6 bedrooms. In whatever configuration.
You can make 3 villas with each 2 bedrooms or 6 villas with each 1 bedroom or apartment building or hotel with a max. from 6 bedrooms. Permit is not talking about salons or kitchens.
Creative architects can assist you in converting your idea's in what you want.
Here under 3 links to maps from the new zone law. This is part from the building permit. The area you can view is from El Catey to Playa el Valle. The maps are from the Ministry of Turism Dominican Republic, april 26, 2012.
