If you’re looking to boost your home’s value, adding more space is a great way to do it. Finishing a basement, building over your garage, or adding a sunroom can make your home more comfortable and more appealing to buyers.
Some projects are simple and budget-friendly, while others take more planning and investment. But no matter your budget, there’s an option that can work for you.
Here are nine home additions that can give you more space—and a higher home value.
Room Extension (Bump-Out)
Cost Estimate: $10,000 to $50,000+
A room extension, or bump-out, adds extra space by either expanding an existing room or adding a new one. For example, you could extend your kitchen for a breakfast nook or add a guest bedroom. It’s a great option for more space without a major remodel. Costs vary based on size and plumbing needs, but it’s an affordable way to increase your home’s value if you have the space.
Sunroom Addition
Cost Estimate: $5,000 to $80,000+
A sunroom gives you extra space and plenty of sunlight without the hassle of bugs, rain, or scorching heat. It’s a bright, comfortable spot for morning coffee, family game nights, or even a home office. There are two types of sunrooms: three-season and four-season. A three-season sunroom is a little cheaper but not great in extreme hot or cold weather. A four-season sunroom costs more because it’s insulated and has heating and cooling, so you can use it all year.
One way to save money? Build your sunroom over an existing deck—as long as the deck is strong enough to hold it.
Turn Your Garage into a Space You’ll Actually Use
Cost Estimate: $6,000 to $30,000+
If your garage is just sitting there, why not turn it into something useful? With a little work, you can create a home gym, game room, or workshop. If you add insulation and get the right permits, it could even become a guest suite or in-law apartment.
The best part? You don’t have to change your home’s layout. Since the garage is separate, the renovation is less messy, less disruptive, and usually cheaper than building an addition.
Building Above Your Garage
Cost Estimate: $10,000 to $45,000+
If you’re running out of space inside your home but don’t want to expand outward, building a room over your garage is a smart solution. This home addition can be anything from a cozy guest suite to a home office or even a small rental unit, depending on your area’s building codes. Keep in mind that garages often lack proper insulation, so you’ll need to add it to make sure the new room stays comfortable in any season.

Finished Basement
Cost Estimate: $4,000 to $80,000+
Got an empty basement? Turning it into a usable space can really increase your home’s value. With a few simple updates, like adding flooring, drywall, and a ceiling, you can create a playroom, home office, or even a home theater. If you want to turn it into a bedroom, just make sure to add an exterior door or egress window for safety.
Turning Your Attic into Living Space
Cost Estimate: $7,500 to $40,000+
If you need more space but can’t afford a full second story, turning your attic into a usable room might be a great option. You can transform it into an extra bedroom, a home office, or even a walk-in closet. The first step is to check what kind of space you have up there. Have a contractor take a look to see what’s possible. It’s a cost-effective way to add value to your home without a big remodel.
Extra Living Unit (ADU): More Space, More Options
Cost Estimate: $60,000 to $350,000+
An accessory dwelling unit (ADU) is a separate living space on your property. It can be a guest house, in-law suite, or rental—built as a standalone unit or added onto your home. What makes an ADU different? It’s fully self-contained, with its own kitchen, bathroom, and living area. This makes it perfect for long-term guests, elderly parents, or extra rental income. Before building, check local rules—some areas have restrictions.
Traditional Home Extension
Cost Estimate: $50,000 to $600,000+
A traditional home extension is a big way to add space to your home. You can add new rooms, like extra bedrooms, bathrooms, or living areas. This kind of addition can be connected to the main house or set up as a separate living space, like a guest suite. Keep in mind, that it requires a decent amount of room on your lot and a good budget since the foundation is usually the most expensive part.
Adding a Second Story
Cost Estimate: $100,000 to $400,000+
If you don’t have much land but need extra room, adding a second story is a great option. This kind of project can be costly because your home needs extra support to handle the weight. But it can be worth it for a growing family who needs more bedrooms or a bathroom. You can even save money by adding just one extra room on the second floor instead of several, depending on your space and needs.
