"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!"

"We bought our home a few months ago, and I just want to say how much we?ve appreciated the way we?ve been treated. From day one, we felt like we weren?t just another sale. The team has been kind, responsive, and really there for us whenever we needed something. They truly care about making sure everything is right and that we?re happy. Mr. Shtienmetz is someone you can tell genuinely loves what he does. He?s involved, he listens, and he stands behind his work. It?s not just business for him, you can feel that he does this with heart. That kind of dedication is hard to find, and we?re very thankful for it. We wholeheartedly recommend them to anyone looking to purchase a home. If you want to work with people who truly care and stand behind what they do, you will be in very good hands."

"I have not completed this project yet. I am still in the beginning stages but so far Hudson valley Home source has been wonderful. Brian Hitt is very knowledgeable and competent in everything he does. I expect everything to be complete around November or December. Feel free to contact me then and I will be more than happy to give my opinion."

"I was very happy with the price and the work that was done to create the room. There were three estimates and this price was what I wanted to spend. I was pleased with the workers who came to complete the project, everyone was very friendly and answered any questions that I asked. A porta potty was placed outside so the workers did not have to come into the house, and it was great that I didn't have to be home when they were working downstairs. They entered and exited through the egress window. At the beginning of the project there were two mistakes made but as soon as I mentioned them to the contractor they were immediately corrected. They notified me through a phone call each day that they were coming and almost always were on time. I would definitely recommend this company,"

"Malik runs a very professional operation. From the time of initial phone contact with Malik (yes, he does answer his own phone) to the final post-job cleanup, this was a hassle-free project for me. Malik's crew showed up promptly each morning, and under the supervision of Malik or his equally capable foreman ("Mr. Z"), every detail of this work was performed in a skilled, highly competent and precise manner. Once begun (except for rain days), the job was continued through completion. Worth noting also is the fact that, although he was aware of my budget limitations, Malik was able to deliver a first-class job which the quality of the finished product reflects. I would enthusiastically recommend him to any Angie's List member (and will be contacting him myself for all future work on my house).

"112 Home Improvement was recommended to me by my cousin.  They had remodeled his home and he was very happy.   We called John about a year before we wanted to begin.  We didn't even know exactly what we wanted.  He offered to come out and help us plan this project.  Once we figured out what we wanted to do John brought out his architect (Tom) and we started the process.  Plans, permits, surveys, variances the list is endless.  I am glad we did this well ahead of time.  Finally 9 months later (thanks town of brookhaven) we had everything needed to begin.  The work began in March and continued through June.  Everything went as good as can be expected.  There were some problems here and there but nothing that we were not prepared for.  In the end our home is beautiful.  We extended and remodeled our kitchen and created a great room, finished our basement, added a master bathroom, replaced our roof and our siding as well as added a deck.  My family and I could not be happier.  We absolutely love our home.  Thank you John and company!!"

Home Building FAQs, answered by experts

The average build timeline for a home is between six and 12 months, with timelines pushing toward the upper end of that range if you’re creating a custom design or need a lot of land preparation before getting started. Hiring a general contractor or a custom homebuilder will help speed up the process, as you’ll see fewer delays between different parts of the build process getting done.

There are energy-efficient options when building a cottage. Select green building materials, high-performance insulation, and energy-efficient windows when designing your cottage. Options such as solar panels, efficient HVAC systems, and LED lighting can lower your utility bills and reduce your environmental impact. Many builders offer energy-efficient upgrades as part of the design process.

Historically, Tudor homes originally stemmed from the 15th and 16th centuries, while Victorians appeared during Queen Victoria's reign in the 19th century. The design and structural differences are significant as well. The many types of Victorian architecture—such as Italianate architecture—typically feature ornate trim, wood siding, wraparound porches, and tall towers on top, such as belvederes. On the other hand, Tudor-style homes feature white stucco exteriors with exposed wooden rafters marking the house frame both inside and out.

Green homes are often more expensive to build, averaging around $200 per square foot compared to the $150 per square foot you’d spend to build a standard home. However, green homes can save you money on your utility bills by consuming less energy or creating energy using solar panels or wind turbines on-site. They’re more expensive to build, but they often end up costing less in the long run.

Local regulations dictate how big an ADU can be, and there may also be restrictions on the percentage of the main residence’s square footage an ADU can have. In most cases, an ADU must be smaller than the main residence, but check with your local building authority to confirm restrictions on ADU size.
