Interior renovations are planned for Sunset Publishing Corp.'s previous headquarters at 80 and 85 Willow Road in preparation to house new tenants of the office space.

According to Carol Donnelly, spokesperson for Embarcadero Capital Partners, the current owners of the property, applications for permits have been submitted to the city of Menlo Park and renovations are expected to be completed at 85 Willow Road in April and at 80 Willow Road sometime in May.

The property, which was acquired by Embarcadero Capital Partners in December 2014, now shares partial ownership interest with Deutsche Asset Management, a move announced Jan. 13.

Deutsche Asset Management and Embarcadero Capital Partners have partnered before as office space developers of the Clearview business park in San Mateo, where GoPro's offices are located.

The two former Sunset buildings, together called "Willow Park," contain 85,732 square feet of office space in a large park-like setting, according to Catherine Wooters, spokesperson for Deutsche Asset Management. The building at 80 Willow Road was designed by Cliff May, described as the "father of the California ranch-style home."

"We strongly believe that (Willow Park) will benefit from a cosmetic and mechanical upgrade focused on preserving the unique character and the amenities that make this property so attractive," said Todd Henderson, Deutsche Asset Management's real estate head.

Ms. Donnelly said the footprints of the buildings will not change, and that the renovations are intended to "marry some of the historic elements with modern bits." The gardens are still being maintained.

They're actively marketing the building to new tenants, she said.
