According to a history of North Beach prepared by historian Carolyn Klepser for the City of Miami Beach Planning Department, the first two parts of the subdivision, platted in 1919, originally stretched from 75th Street to 87th Terrace and encompassed both sides of Collins Avenue. The current neighborhood of Altos Del Mar is slightly smaller, running from 76th to 79th Street east of Collins and taking up the east and west sides of the private road called Atlantic Way.
Originally, the Tatum brothers smartly planned expansive 250-foot by 125-foot-long lots. The 12 Lots on the beach continue to be expansive at approximately 16,000 square feet. Some of the remaining historic single-family homes date back to the mid-1920s and late 1940s, and range in style from Mediterranean Revival with stucco walls and barrel-tile roofs to Moderne with curvy lines and understated details.
General Real Estate's redevelopment plan promised to upgrade utilities and pave Atlantic Way. Any concerns nervous neighbors expressed that new structures might be oversized or incompatible with the character of older homes were unfounded. Altos Del Mar had been designated historic locally back in 1987, meaning a modicum of control over the design of new homes would be exerted the City of Miami Beach Historic Preservation Board by city boards. Ultimately, a dozen homes will be constructed on two lot configurations (6,250 square feet and 16,000 square feet). And by the looks of those already underway, an interesting neighborhood is taking shape. Brand new contemporary-style homes share the area with Bermuda-style, and Mediterranean-style properties.
And if having the Atlantic Ocean at its doorstep isn't enough, Altos Del Mar, similar to nearly every neighborhood in North Beach, will have a park. Altos Del Mar Park will be redeveloped to a statement park with new landscaping, walkways and direct access to the Ocean Terrace redeveloped hotel, restaurants and retail stores.
