Need more space?  Thought about building a new home, but love the one your in?  You might consider adding on to your existing home.  DeCosta Construction can help find you and build you an alternative that gets you that much needed space without the expense of starting from scratch.We can add to the side, or we can build up, as shown in the home to the left.  We took the roof off of this little ranch, added a second floor, and turned it into a nice cape cod style home with two dormers on the front and a full dormer in the rear.  And best of all, we did this in the most economical fashion, saving the homeowner thousands of dollars.So, if expansion is in your sights, then Contact Us and we can sit down with you and explain how we can meet your needs.
