What is an Addition?

An addition is an entirely new structure that is added to your home’s exterior to expand the conditioned livable square footage. Seem pretty straightforward right? When considering this type of home improvement, know that it is viewed as new construction and not a renovation. There may be a few things more that go into your addition project than a typical remodel. 

– Framing

– Structural Reinforcements

– Foundation

– Code Upgrades

How to Build an ADdition in Denver

Building an Addition is not like your typical home improvement project. With remodels and renovations, most of the work are cosmetic finishes. But when building additions, you are creating an entirely new structure and attaching it to your home. Therefore beyond simple framing, drywall, and flooring; building an addition require:

– Excavation

– Foundation and Drain

– Structural Improvements

– Framing

– New Utilities


WHat is the cost to build an ADdition?

If you are looking to expand on your property or simply maximize your space – ADU construction might be the best solution. However, building an entirely new and detached dwelling unit is a large undertaking. Homeowners should understand that this type of project is typically more costly than remodeling. ADU construction costs can vary widely due to finish selections, scope of work, existing site conditions, and more. Every property is unique so contact Sustainable Design Build for a free consultation!
