Dynamic determination of building fit on lot parcels

A system for dynamically determining lot-fit, comprising:

• a computing device including at least a processor, an electronic graphic, and a memory, the computing device configured to:
• display on the electronic graphic a menu of baseline building designs and permit a user to select one of the baseline building designs, the baseline building designs having corresponding digital design files saved in the memory, the digital design files including baseline footprint sizes of the baseline building designs;
• display on the electronic graphic a menu of building modification options linked to the selected baseline building design and permit a user to select one of the building modification options, the digital design files including as-modified footprint sizes of the baseline building designs with each of the building modification options that is linked to the respective baseline building design;
• using the processor to compare the as-modified footprint size of the selected building modification option for the selected baseline building design to one or more permissible build envelopes of one or more lot parcels, the lot parcels having corresponding digital lot files that are saved in the memory and contain the permissible build envelopes;
• display on the electronic graphic whether the selected baseline building design with the selected building modification option fits within the one or more permissible build envelopes of the one or more lot parcels;
• and
• extract elevation data from one or more of the digital lot files, generate one or more lot topographies for the one or more lot parcels based on the elevation data, and display a three-dimensional graphic of the selected baseline building design with the selected building modifications on the one or more lot topographies and within the one or more permissible build envelopes.
