Let’s face it—you’re not just expanding your space. When you’re looking to add square footage to your home, you’ll want to ask the right questions about the addition. You’re increasing your home’s value, enhancing your lifestyle, and creating an area that works best for you. But before you start knocking down walls—or putting new ones up—consider your answers to the questions below. 

1. What type of space are you interested in adding to your home?

A sunroom addition is a very different project from a home office, which is why this question is important in the initial consultation with a professional contractor near you. If you’re interested in a garage addition that can double as a home gym, your contractor may work out a plan that addresses both. Make a list of the top three types of rooms or spaces you’re looking to add, and your contractor can tell you what’s possible. 

2. When do you need this work done?

Are there visitors arriving next year? Then you’ll likely want the addition done beforehand. Maybe the home addition coincides with a new addition to your family—whatever the case may be, talk to your contract about timelines. The more specific you can be about your expectations, the better. Take your local climate into consideration as well, as a project is likely to be delayed if there is a blizzard.

3. How would you describe this project?

It’s possible your addition project needs the bare minimum— framing, drywall, paint, and texturizing. On the other hand, specific design features such as a fireplace, custom tile and molding, and other details may require a different level of craftsmanship. It helps to have inspirational photos to show your contractor exactly what you have in mind. Your preferences can impact your budget and timeline.

4. What kind of addition do you want?

Are you adding a garage or expanding your home to have another level? The complexity of the addition can significantly change the scope, timeline, and price of the project. So long as you are definitive about the type of addition you’d like, you can expect your contractor to provide examples of similar work they’ve done and ask follow-up questions about your needs. 

5. How would you describe your design style?

The answer to this question can change what type of contractor you hire, as some may specialize in specific design styles. If you don’t have the architectural savvy for specific terms, look to Pinterest or Instagram for images of rooms you like. Concrete examples allow your contractor to make your dream addition a reality.
