Frequently Asked Questions

The timeline for your home addition project will vary from project to project. There are several factors that go into this timeline, including the size of the home addition project, the permitting process, and the selections process to name a few. A home addition project can take anywhere from 3-12 months depending on the many factors that are involved. Allow 4-12 months for the design and permitting process, and 6-12 months for construction.

To start the home addition process you should have a vision for how you want to use the space, and how you want the space to look. The initial stage of your home addition process will consist of an initial phone consultation with one of our Creative Director who will learn more about your project and help you determine the next steps. From the initial phone call you will have an in-home consultation with one of our Senior Designers who listen carefully, discover your core needs, and align them with your vision for the project. Once we have decided to work together you will meet the rest of your design build team, including your Project Manager who will oversee the construction process.

Financing a home addition will mainly depend on two things: desired value to add to your home and your personal valuation. However, with the DMV area being a central hub for home appreciation, the search for financing should not be a problem and that’s where we come in. We are more than happy to help you find multiple local banks and mortgage lenders that will thoroughly explain the process and options you have readily available. One of the ways we help many clients in Washington DC enjoy their homes sooner, is through flexible, secure, and affordable payment plans. Our financing programs cannot be found at your local bank and are often not available to “Chuck in the Truck” or your average contractor. Enjoy a range of programs that include absolutely NO money down and even NO monthly payments for up to 18 months, your Hammer design consultant will be able to find a promotional plan that makes your project completely affordable.
