456 development group, llc is developing an exclusive property on some of the most desirable waterfront in the United States. The project will develop a single-family waterfront property named “100 Crescent” on eastern Long Island in New York. The home will be outfitted with all the luxury amenities a homeowner would desire.


The team at 456 is headed by two motivated individuals in the prime of their careers who are seeking to establish a new standard of high-end home development, while maintaining a careful eye on budget and schedule. Often times lack of experience or creative confidence creates conditions in the final product that are unsightly. The primary assets brought to this project by 456 development group that give high confidence are:

  • The team's proven track record of high-end design and construction backed by satisfied clientele
  • The ability to value engineer without the unknown quantities of external subcontractors
  • Experience in large-scale job management & problem solving guaranteeing an efficient construction schedule with the absence of cost overruns

The goal of this project is to use diligence, decisiveness and sophistication to manage all phases of design and construction with a high priority being placed on quality without compromise. 456 development group is comprised of developers, construction managers and design professionals with extensive experience in high-end design and construction. Often times projects of this nature are commissioned to a variety of consultants and subcontractors that can increase overhead costs and affect quality control; 456 development group is a fully integrated, self-supporting entity that limits the use of “out of house” services in achieving its goals. Less dependence on outside subcontractors & consultants focuses the budget on the product.

Keeping it simple while executing at a high level is the team’s focus.
