Hello Tresha,
It appears you did not have the property checked by a lawyer before buying it. There are so many things associated with properties regarding ownership, location (If by the sea, there will be a restricted construction zone a certain distance from the high tide line), stability of soil if at the edge of a ‘level drop’, whether zoned as farm land (In such a case, only a farmhouse can be allowed for construction), whether zoned as a single family/multi family plot (The plot coverage and maximum built up area will be defined by the Municipality/Local authority) … So many things to consider. Some plots may be declared as 'green zones (No construction can come up there except maybe temporary by nature e.g container house, eco-house OR, no habitation whatsoever!).
It is good that atleast now you have a lawyer representing you (and also an architect). They should be able to study the legalities of the process and advise you better. Once the plot is cleared for construction, and you have the Floor Area Ratio (FAR)/ Plot Coverage defined, only then can you start the design effort. I could be of more help to you at that time. I pray that all goes well with the process. Keep in touch!
