A General Contractor Reveals Secrets to Addition Building

I created these room addition plans to transform my general contractor experience into information people can use to make these complex renovations a lot simpler to research and eventually build. My mission is to simplify the process of building on to your house. There are a lot of scattered articles all across the internet, but many of them are written by webmasters and bloggers instead of actual contractors. I decided to give people access to the correct method of addition building as well as provide them with access to my archive of home addition plans, that I used to actually renovate people's houses in Connecticut. The room additions above are the most popular projects being built in America today. 

You could look elsewhere, but why would you get your remodeling advice from a writer or blogger?
