You’re Unique, And So Is Your Home Addition Project

How much does having more room in your home improve your life? Think of an area in your home impacted the most by not having the desired space:

  • Perhaps you have dreamed of having a “man cave,” craft space, game room, or larger family room?
  • Think a primary bedroom with spa-like bathroom addition could change how you feel about your home?
  • Maybe you need to build an Accessory Dwelling Unit (ADU) or in-law suite for an elderly parent?
  • Starting a new business and need a Home Office or Den?
  • Need additional workspace in the garage?
  • Dream of being closer to nature via a new sunroom or porch?

No matter the use, Enterprise Contracting’s years of experience building additions and highly skilled craftsman make it the perfect partner for any home remodeling project.

Featured Project

Two Story Addition

The clients were thrilled!
