"Dave Nessel and his stellar company, Unique Construction NY Inc. are the BEST. Allow me tell you why- On May 15th 2022 at 5:45 p.m., my house was hit by, what electrical engineers later estimated, was at least 80,000 volts of lightning. That huge, direct surge of energy destroyed all the systems and contents that made my house more than four walls and a roof. In addition to the bolt of lightning destroying all the systems in the house, it caused a violent, destructive fire. Thankfully I was home at the time of the incident, or the house would have quickly burned down all the way down and my pets would have suffered a terrible fate. Still, after all was said and done what had been my home for seventeen years was reduced to nothing more than an outer shell. I was immediately forced into the position to find, hire, and organize tradesmen from all specialties, negotiate the endless complexities of homeowners insurance, all while trying to find a place to live and continuing my self-employed full-time work schedule. It quickly became clear I needed the services of a general contractor. I interviewed a couple, but as soon as I met Dave I knew he was the man for the job. Dave was always on time or early. He went through the house with a fine tooth comb for hours, noticing things and problems from the destruction I hadn't noticed. His expertise of every level of construction and understanding of all aspects of housing systems (electrical, plumbing, etc) was unmatched by anyone else I had interviewed. Additionally he had an understanding of the homeowner insurance protocols and was able to interject as a supporting role (only when needed, Dave never undermined me -I'm a single female homeowner-) with professional, easy to read, paperwork, accurately demonstrating all costs. I'm confident his detailed documentation made the long slog of negotiations with my insurance representatives a little easier. Under his expert guidance, his company gutted and rebuilt my old house to beautifully modern standards while maintaining its historical charm. The rebuild came in precisely on budget and two weeks early. Dave's company Unique Construction handled my complex situation with upstanding processional skill, old fashioned kindness, and outstanding forthrightness. Dave and his crew treated me with respect, rebuilt my home, and provided a little hand holding & TLC when it seemed I needed it and I'm eternally grateful. Anyone reading this should hire Unique Construction!"

James Phillip Golden Architect
High end architect specializing in making a house feel like home! I make people’s dream homes a reality. There is nothing more satisfying to me then improving the quality of life for my clients and giving them a house that they are able to make into their homes. I have been a licensed architect since 2015 and am currently registered in Rhode Island, Connecticut, New York, Maine and Massachusetts. With my NCARB certificate I am able, if necessary, to obtain reciprocal licensure throughout the country in a short time period. I am inspired by our local built environment, humble materials, classical building forms and traditional building details. I have a strong interest in the reinterpretation of classical building forms, blended with contemporary open floor plans. I have a stronger interest in helping to guide my clients to ways of improving the quality of their lives through adapting the built environment to meet their needs.
