The final beam was placed Wednesday at the new Ronald McDonald House in Baltimore.
The organization held a topping off event to celebrate the milestone in the construction.
The new house is being built in the historic Jamestown neighborhood in east Baltimore.
Wednesday’s event included a beam signing and a countdown by an 8-year-old boy who is a returning guest at the house.
The beam was raised with 563 dangling hearts, to represent the number of families turned away from the current house in 2017 due to limited space.
The $30 million, 60,000 square foot house will be able to serve twice as many families.
"It’s a pretty emotional day but in the best way possible. There's no coincidence that its Valentine's Day, we call this the house that love built so it’s a perfect day to top it off and this time next year we'll have our first families moving in,” said the President and CEO of Ronald McDonald House Charities Baltimore Sandy Pagnotti.
The new house will have 54 guest rooms, including nine suites designed for bone marrow transplant patients.
Construction is on schedule and should be complete early 2019.
