What are the benefits of a home addition?

The benefits of a home addition not only include receiving a high end renovation to meet your aesthetic and practical needs, but you’re also adding value to your home that offers a great return on investment.  Washington DC and the surrounding counties are a strong, central hub for home appreciation, so any addition to square footage can be beneficial.  Plus, you get to make the space exactly how you want it based off of how it will be used and your aesthetic preferences.

Home additions come in a few basic types to address homeowners' needs for living space, cost, and style.  The following are different types of additions in Washington DC priced according to older homes with aging plumbing, electrical systems, settlement, etc issues. on the higher end and projects in newer homes to be on the lower end of the indicated figures.

With all construction parties being on the same team, it brings total accountability to the firm.
