A former Acme supermarket could become a preschool, one of Greenwich's most recognizable estates could be torn down, and a century-old North Street home is one step closer to historic protection after a busy Planning and Zoning Commission meeting Tuesday.

Here's what residents should know:

Former Acme could become Goddard School

The vacant Acme at 160 W. Putnam Ave. could be converted into a Goddard School serving up to 216 children from infancy through age 5.

Plans call for 10 classrooms, a gym, kitchen and outdoor playground. The applicant says staggered drop-off and pickup times would help reduce traffic on West Putnam Avenue.

Former Trump estate slated for demolition

The owners of 21 Vista Drive want to replace the property's existing mansion — once owned by Donald and Ivana Trump — with a new luxury home.

The proposal includes a roughly 17,000-square-foot residence, pool, tennis court, guest quarters and other amenities on nearly six acres. The property sold for $31.5 million in 2024.

Historic status considered for North Street home

The commission also began reviewing whether the 1917 William B. Tubby Jr. House at 352 North St. should receive local historic designation.

The Tudor-style home was designed by noted Greenwich architect William B. Tubby Sr., who also designed the original Greenwich Hospital and Hamilton Avenue School.

Neighbor objects to Cos Cob ADU

A proposal to convert an accessory building into a dwelling unit at 21 Grove St. in Cos Cob drew objections from neighboring property owners, who questioned the structure's history and its location near the property line.

No votes were taken on the projects Tuesday. Most will return to the commission for public hearings or future review in the coming weeks.
