"We have worked with Anthony from TAS Construction since 2006. He built a 2nd story addition on our home and completely remodeled the first floor. His work and crew are professional and courteous and you see right away that Anthony cares about his clients. After Hurricane Sandy destroyed the 1st floor of our home, Anthony was there to help us repair the water damage almost immediately. Fast forward to August 2020, and Anthony made time to give us an estimate for some recent storm damage in a few hours. He knows his stuff and has a great eye and ideas that look amazing when implemented. We constantly get compliments on our home and never hesitate to recommend him ."

"Mack Rubio does fantastic woodwork. He and Juri responded within minutes of my request for new porch stairs and railings, as well as replacement of rotted fascia and siding. His work is solid, fast, and precise. Excellent skill and craftsmanship. His estimates are affordable and his team are always punctual and professional. This is my first home purchase and it is a fixer-upper, so I will definitely be calling Mack again for assistance with all of our home improvement projects. I highly recommend Handy Mack for all home repairs and renovations!"

This is the 2nd major project I contracted Art DeRosa & Co for.  The 1st being 4 years ago a major living room/family room renovation which was hugely successful.  That 1st experience led me to award Art (after several other competitive quotes) this 2nd and far larger & more complex project.







Overall it went well but this was a complicated project encompassing all the typical trades and expertise of building a new luxury house but far more complicated because it was a renovation performed while we were living in the home. Dust partition walls with wood framing had to be erected in several locations in the house which included temporary doors for entering and egress in certain areas of the remaining living areas of the house in order to protect the remaining house from dust and demolition , as well as, provide privacy for us during construction. 

Experience, Experience, Experience and Professionalism, Professionalism, Professionalism are the hallmarks of Art DeRosa and company.  He is a seasoned performer and pretty much seen it all.  Art has such a vast amount of home construction experience in both hi-end and medium end homes that he can draw upon a wealth of knowledge in all construction disciplines to implement a fine finished result.  As a former tool and die maker his penchant for hi-precision finish work yields highest quality appearances to things like moldings; trim; windows; doors; floors; etc. etc. 

This complex renovation project lasted 7 months which was within the initial time estimate given at the beginning and Art DeRosa and team were here every single day, day in and day out,  bright and early during that time frame. He did not start any other projects and stayed on the job day-in and day-out even when other sub-contractors such as plumbers and electricians were on the job site excluding his people from doing any other work. Art DeRosa and team were here every single day until final signoff.

I would not hesitate to recommend Art DeRosa & Co for any planned New House and/or House Renovation of any kind.

"Mike and his crew came in, they were organized,professional,skilled at their jobs. We put addition on house and they opened up the roof, did the work and had the house covered. They planned it between all the rain storms we were having at the time. Took a while to start because of the rain but when weather opened up they came in and did a great job. The quality was great. Mike walked us thru various stages so that he was completing it as we wanted. He was here every day his guys were when I know most companies drop guys off to fend for themselves and the homeowner has no idea what’s going on or who to talk to. I would defiantly hire this crew to do any future modifications."

Barndominium Builders FAQs, answered by experts

Prefab sheds can be worth it, depending on your needs and goals. If you want to build the shed yourself or have a quick project turnaround, then a prefab shed will likely be worth it. If you want something more customized, then starting from scratch may help you achieve your goals better than a prefab could.

You don’t typically need a permit to build a shed, but it’s best to check with your local city clerk to make sure before you start the project. Every town, city, and municipality can have different rules when it comes to any home improvement project. Homeowners associations sometimes have restrictions on the materials you can use on your property as well.

Generally speaking, building a swing set is cheaper than buying a prefabricated one, but this assumes you have all the tools and knowledge to complete the project. The average cost to build a swing set is $514, but you should also factor in the time and effort it will require—if you don’t want to give up your weekend, it’s worth considering buying instead of building.

Whether you should choose a flat roof or a sloped roof depends on your particular situation. Flat roofs tend to be less expensive to install. However, sloped roofs have longer lifespans and stand up better to heavy snow and other inclement weather.

Keep in mind that even a flat roof needs to have a slight slope, usually around 1/2 inch for every foot. If it is completely flat, water will pool and cause damage, either from weight or leakage or rot.

This answer varies based on where you are, but most states require that all homes are greater than 320 square feet. Remember that four walls are not the only requirements—windows, closet space, minimal ceiling heights, and indoor air quality are also factors. Each state and municipality differs, though, and as some don’t consider tiny homes permanent shelters, you’ll need to check to ensure you aren’t violating any local or state laws with your build.
