ABOUT US

Upright Contractors is our name and Inside Additions are our specialty as well as our official trademark. We have hundreds of completed lofts and room additions. We are the highest rated loft addition builder in Southern California with an exemplary A+ rating by the Better Business Bureau. No one builds loft additions better than Upright. We are the quality leader in our field with 100% customer satisfaction for our entire 10 year history.

Whether your addition is simple or fully custom, a great addition starts with clear visual design plans. We use both floor plan view and 3D graphics to show you every aspect of your new addition before it is ever built.
