"I recently moved to a new home and needed help installing a mailbox. I reached out to Bill from Mason Carpentry and he was quick to respond and willing to assist. He came to my home only a couple of days later to install it. Bill was great, incredibly friendly and professional. As a new homeowner, I need all the help I can get and I will absolutely be using Bill again for other projects. I would definitely recommend Bill!"

"It was a pleasure dealing with Star Dynasty from start to finish in the reconstruction of our deck. Their estimate was done professionally and the work progressed quickly, professionally and completely. We are very pleased with the outcome and do not hesitate to recommend them to anyone interested in having work done on their property."

"

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.

"The roof of my metal shed collapsed during the last big snowstorm. I called several companies for estimates and Ben came same day right away. We spoke about options, he explained what needed to be done, and how he would proceed, He was detail oriented and knowledgeable. I felt comfortable with his approach. I highly recommend Dynamic Exteriors! The final product is a very strong, well built product that will withstand any storm for years to come!! Thanks Ben and Cesar!!"

Barndominium Builders FAQs, answered by experts

It can, especially with the rising popularity of treehouses that go beyond the ones designed for kids. Adults can now use them as office spaces, yoga studios, or quiet treetop retreats. That said, a treehouse can appeal to families with children or adults who might want to convert it into a space of their own. Depending on the buyer, they may be willing to pay extra for the unique feature.

Technically, most states allow tiny homes, but it depends on the definition of tiny and whether the structure is permanent. Zoning laws regarding home size and construction are significant factors. For instance, a tiny home may be legal as a recreational vehicle in most areas, but you may only install it on a property if it complies with building and zoning codes.

It’s much less expensive to build a house with wood. This is because wood is relatively inexpensive, strong enough to endure decades or even centuries of weathering and pressure, and is easier to replace if there are issues. The cost of stone houses are incredibly expensive, heavy, time-consuming to build, and difficult to repair. 

There's no simple answer to which is less costly: wood or metal-framed homes. In most cases, metal building components cost more than wooden ones, while entire metal buildings cost less than wooden versions. However, regardless of the exterior framing or structure, each must meet similar building codes. This means that the costs are about the same, even considering that wood will require more maintenance than metal over time.

Whether a prefab home is worth it or not will depend on your personal needs and preferences. Overall, prefab homes tend to cost less than traditional homes, although they also tend to have lower resale values. Another thing to consider is that prefab homes usually last 50 to 60 years or longer, while traditional homes last 50 to 100 years or more.
