WASHINGTON — Despite opposition from many local residents, the Trump Organization on Thursday received approval in Scotland for what will be the largest new company-financed real estate development project since President Trump was elected: a major expansion of its golf resort near the northeast port city of Aberdeen.

The plans call for the construction of 500 homes, 50 hotel cottages, and sports and retail complexes next to the Trump family’s Aberdeen golf club, which has struggled financially since the company purchased the property more than a decade ago. A second 18-hole golf course is also planned on the 1,500-acre site, north of Aberdeen.

The first phase of this project is more modest: about 80 homes and five hotel lodges, documents show.

But unlike most of the recent Trump projects, this is not simply a matter of selling the Trump name or hotel management services. The Trump Organization would be the real estate developer on the project, which could cost an estimated $180 million if it is entirely built out as approved this week.

The Trump Organization is already attempting to sell these new homes, as part of what it intends to call Trump Estate, with the highest-end homes not far from the North Sea coastline selling for prices of more than $1.6 million.
