Hammond Residential Real Estate’s Dana DeSimone, a senior sales associate with the company’s South End office, has been named exclusive listing agent for 121 West Newton St., a new residential development in Boston’s South End neighborhood.

121 West Newton St. is a five-story building that will consist of a penthouse duplex and a parlor triplex. Each unit will measure approximately 1,665 and 2,536 square feet, respectively, and feature high-end finishes such as designer kitchens and bathrooms, remote controlled environments and new mechanical systems. The property is currently under construction and slated for completion this spring.

"Having previously marketed renovated townhouses in the neighborhood on behalf of Renaissance – 26 Milford St. and 34 Dwight St. – I can attest to the high-level of quality, craftsmanship, and detail that 121 West Newton St. will feature," DeSimone said in a statement. "In a market where supply is low, we anticipate a great deal of interest in these units."
