The makeover of One Soho Square has snared the offices of MAC, a cosmetics company.

MAC has signed a lease for 86,000 square feet on the western side of the property that will include splashy new glass penthouse floors and roof deck, The Post has learned.

Sources said the firm will move to the 10th floor along with the dramatic glass penthouses on the 11th through 13th floors that were just added to the original manufacturing building.

Located at Sixth Avenue and Spring Street, the double building overlooks the Soho Square triangular park.

The asking rent was $125 per foot.

MAC was repped by a CBRE team led by Steve Siegel, Greg Tosko, Lewis Miller and Sacha Zarba.

Owner Larry Gluck’s Stellar Management was represented by a Newmark Grubb Knight Frank team of Brian Waterman, Andrew Peretz, David Malawer and Brent Ozarowski.

Stellar has also added a new glass lobby and center elevator core to the two adjoining buildings.

Negotiations were revealed last fall by the Real Deal, but the floors weren’t specified.

The building was purchased in 2012 for $200 million. Stellar bought out partner Rockpoint earlier this year, revaluing the building at $650 million.

Other tenants include Warby Parker. Last week, Trader Joe’s announced it will open a store there.

But longtime tenant Springer Science Business is battling to retain a 100,000-square-foot space, with a trial scheduled for later this month.

Now owned by Estee Lauder, a favorite of professionals and consumers, the makeup company has small offices on Prince Street. It has sales in more than 120 countries.
