Thinking about expanding your home in Washington DC? Whether you need more space or want to upgrade your living areas, understanding the costs is a big first step. From kitchen expansions to second-story additions, this blog covers all you need to know about home addition costs and design ideas.
Let’s dive into a few of the most common home additions and see how you can transform your living space!
This might sound like a silly question, but there are two main types of additions for you to think about when you want to add a new space to your D.C. home.
An addition can either be within the existing footprint of your home or involve adding extra square footage. Adding square footage typically means building out the foundation and roof, which naturally increases the cost.
A professional and trustworthy design-build team can assess your home, learn to understand your goals, explain the process with transparency, and help you decide if adding square footage is necessary to achieve your design to give you the space you need.
Let’s explore the different types of home additions and their costs in the DC area.
(Pro Tip! If you don't see the addition you would want for your home on this list, we've included a few more ideas below, and you could reach out to us to find out about what your unique design could cost.)
Feeling a little cramped in your kitchen? Maybe your cabinets are overflowing, you desperately need more natural light, or you're tired of living a life sans a kitchen island. Expanding your kitchen within your home’s existing footprint can cost around $180K.
A kitchen expansion can afford you and your family more cooking space, a back kitchen, extra storage, a larger dining area, or a cute little breakfast nook.
This type of remodel can include new and additional cabinets, more counter space, new appliances, and even that coveted kitchen island.
The sanity a larger kitchen can give you and your family is invaluable. From your everyday routines to entertaining dinner guests and hosting special occasions, a larger kitchen just makes everything easier.
Adding a primary bathroom to your home typically costs between $200K and $225K. This type of remodel is going to add to your home's square footage and your quality of life.
This addition can transform your primary bedroom into a luxurious suite. Imagine morning routines starting off the way they're intended—peacefully, well-lit, and with everything in its place with plenty of storage.
Design ideas include:
Adding a full bathroom within your home’s footprint can cost between $65K and $90K, while adding square footage to create the addition can range from $200K to $225K.
An additional full bathroom is often necessary for growing families or homes with frequent guests. Morning routines with multiple children will go smoother, your guests won't have to share a bathroom with the kiddos, and you'll have more storage so bathrooms can (hopefully) stay neat and tidy.
Design ideas include:
Mudrooms and laundry rooms are must-have additions for any home. Adding these rooms within your home’s existing footprint can cost between $30K and $50K, while building out can range from $200K to $250K.
Mudrooms keep dirt and mud from being tracked further into the home. No longer should you find little piles of random items, backpacks, leashes, or dirty shoes strung about the house. At least, that's the goal. And don't get the wrong idea with the name; a mudroom can be a very stylish space with finishes that complement the rest of your home.
Mudroom design ideas include:
Laundry rooms are far superior to the laundry closet in every way. Having a complete room with enough space to store, fold, stack, sort, and hang will keep your hallways free from baskets. Many homeowners prefer to have their laundry room near the kitchen, and it's easier and less expensive to place plumbing lines near where they already exist.
Laundry room design ideas include:
Converting your attic into a livable space typically costs around $250K in D.C. If your attic sits empty—except for that collection of cobwebs—you're missing out on a lot of livable square footage! Just like an unfinished basement, converting your attic can give your family that space you've been wanting.
Design ideas include:
Adding a second story to your home is a major project and starts at $400K and can go up from there. There are three main types of second-story additions: a partial second story, a full second story, and a two-story addition (extending the home vertically and horizontally).
If your family is growing, you're planning to move in an older relative, or you've simply always wanted more breathing room, a second-story addition opens up a whole world of possibilities!
These addition ideas can significantly enhance your home’s functionality. Cost averages aren't available for these specific additions because they're often part of a larger remodel, like a whole home remodel, basement remodel, or attic conversion.

Yes, you will definitely need a permit to build an addition in Washington D.C. Permits ensure that your project complies with local building codes and regulations, making sure your space is safe and upholds the highest quality standards.

Working with a knowledgeable design-build contractor can help navigate the permitting process smoothly, ensuring all legal requirements are met without you having to do a load of homework to stay on top of it.
Absolutely! Home additions generally offer a high return on investment (ROI), especially for key areas like kitchens and bathrooms. Besides financial gains, additions enhance your quality of life by providing extra space and improved functionality. Whether it’s for a growing family or increasing your home’s market appeal, an addition is a wise investment for value and quality of life.
Finding a reputable company for your home addition is a big deal. Here’s how to ensure you choose the right one:
Review the company’s portfolio to see examples of their past projects. This will give you an idea of their style, capabilities, and attention to detail, ensuring they can handle your project and give you the design and function you're looking for.
Check online reviews and testimonials to learn about the experiences of past clients. Look for consistent positive feedback on quality of work, reliability, and customer service. You'll want to read more reviews than you think you need to in order to find patterns in other homeowners' experiences.
Meet with potential contractors to discuss your project. This will help you gauge their professionalism, expertise, and how well they understand your vision. Arrive with a list of questions and take notes to keep things straight. Pay attention to your instincts; this is a team you'll work with for months, so you'll want to ensure you will be able to build a foundation of trust.
