Diamond Bar Home Remodeling
There are a fair many homes in beautiful Diamond Bar communities that have a unique feature called open-to-below. This is when you have a two story home and a portion of the square footage has been left vacant. That's right! Empty space over head or otherwise known as a high cathedral ceiling. Those big open spaces are great for making your home feel big and open and majestic, but many homeowners have figured out when space really matters you can fill in the missing floor and gain a whole new bedroom addition or open loft, or move the laundry room upstairs where it belongs. 

Truplans has specialized in designing this unique type of room addition for more than 22 years now. Watch for more homes being converted in different nearby cities. So popular that every city is now getting it's own page. Remodeling company Diamond Bar for this specialty is no exception. New project being posted to this page beginning in March 2026.
