President Donald Trump has showcased another major construction project at the White House, putting the spotlight on a new granite helicopter landing area being built on the historic South Lawn.

Trump gave reporters a closer look at the nearly completed helipad on Wednesday, August 19, highlighting the materials and design while presenting the project as both a functional upgrade and an improvement to the White House grounds.

The new landing zone is designed to accommodate the more powerful VH-92A Patriot helicopters used for Marine One. Trump has said the aircraft’s powerful exhaust was damaging the White House lawn, prompting the decision to replace the traditional landing area with a more durable granite surface.

During his tour, Trump even signed a granite slab that is expected to become part of the helipad. The landing area will feature an elaborate presidential seal carved into the granite, adding a distinctive ceremonial touch to the project.

The president also revealed another renovation: an asphalt driveway on the south side of the White House was replaced with white granite, another change Trump said better matches the appearance and significance of the presidential residence.

The helipad was first publicly confirmed in July, when Trump said helicopter manufacturer Sikorsky would finance the project. At that time, he estimated its cost at up to $6 million.

The project joins a growing list of changes Trump has pursued at the White House, including renovations to the grounds and the much larger ballroom development connected to the East Wing.

With the granite helipad now nearing completion, Trump is once again placing his background in real estate and construction at the center of his efforts to reshape parts of America’s most famous residence.
