President Trump is discussing plans to install a helipad at the White House to prevent powerful new Marine One helicopters from damaging the South Lawn, according to people familiar with the plans. The helipad would be the latest renovation to the historic White House grounds since Trump began his second term. The president has paved over the Rose Garden, installed a black granite walkway along the West Wing Colonnade, redesigned the Oval Office, placed two large American flagpoles at the front and back of the White House and demolished the East Wing to make way for his 90,000 square-foot ballroom. Trump, a former real-estate developer, has been involved in every detail of his construction and renovation projects, and has discussed the design of the helipad with associates.
