Frequently Asked Questions

Naturally, you want to start by considering what rooms will be expanded or created with the addition’s construction. What are you hoping to accomplish? How will it enhance your experience and family life inside the home?

Ask yourself how big you want the addition to be. How many square feet you plan to add will impact many things about the project from the scope to the cost to the impact it has on your life when completed

Consider not just the space you will be adding, but how it will experientially and physically flow from the original floor plan into the space you’re creating with the addition. Whether you are opening up a great room or adding additional rooms to the home.

If you live in an HOA community as so many do, there are going to be specific regulations about what your home can look like externally and certain features you can add. Be sure to check with the neighborhood policies before you begin.

Remember to consider that additions don’t appear overnight. They take months to plan, then open up the house and build. Your homelife will inevitably be disrupted. The only question is by how much, for how long, and what you will do to maintain a functional routine during construction.
