2020 ALTON is a brand new green home currently under construction in Miami Beach, FL. 2020 Alton is pursuing a LEED rating of Platinum. It will be the first home in South Florida that we know of to achieve this status. 2020 Alton's conception was a joint effort between architect Ari Sklar, developer Matt Lahn, and general contractor Robert Arkin. On a lot size of 58' x 120', the city imposed restrictions of a single family home limited in size to 3,200SF. Due to the setbacks imposed by the city, the resulting buildable area is only 32FT wide. The allowable height is also approximately 32FT.
