How Do You Add an Addition to Your House?


When adding an addition to your house, it's important to consider the type of room you need and its ideal location. For instance, a kitchen or family room is best suited for a bump out on the main floor, where it can easily connect to existing living spaces. Bedrooms and bathrooms are often added by building up, utilizing the space above the ground floor.

If you’re looking to create a private retreat or a functional workspace, converting an attic or garage can be an excellent choice. Each option offers unique benefits, and the right choice will depend on your specific needs and the layout of your home.

Expand Your Kitchen:

A kitchen expansion is perfect for homeowners who love to cook, entertain, or simply need more space for their family. Consider adding a spacious island with seating, smart appliances, and ample storage to make your kitchen both functional and stylish.

This addition can be achieved with a bump out, extending your kitchen into your backyard or side yard, seamlessly blending with your existing layout. With an expansion, you can gain extra counter space for meal prep, a dedicated area for casual dining, and top-of-the-line appliances that make cooking a joy.

You can also incorporate features like a walk-in pantry, custom cabinetry, and elegant lighting to enhance both the aesthetics and functionality of your kitchen. Through expert design, a kitchen expansion can transform the heart of your home into a welcoming and efficient space for family and friends.

Create a Primary Suite:

Adding a primary suite provides a luxurious retreat within your home, offering privacy and comfort. Your primary suite could include a spacious bedroom with a walk-in closet and an en-suite bathroom featuring a soaking tub and double vanity.

This addition can be created by building up, adding a new level to your home, or as a bump out to your main floor, ensuring you have a serene space to unwind. Picture yourself unwinding in a beautifully designed space with high-end finishes, custom storage solutions, and a tranquil atmosphere.

Your primary suite can also include a sitting area, a fireplace, or even a private balcony to really feel like a retreat right within your home. With careful planning, adding a primary suite can significantly elevate your living experience and add substantial value to your home.


Add a Bathroom:

Adding a bathroom can greatly enhance your home’s convenience and value, especially for growing families or frequent guests. Design ideas include a walk-in shower, elegant fixtures, and plenty of storage. Bathrooms can be added as a bump out near existing bedrooms or converted from unused spaces like closets or portions of larger rooms.

Consider features like heated floors, a double vanity, and modern, energy-efficient fixtures to create a comfortable and stylish bathroom. Adding a bathroom not only reduces the morning rush but also provides a private, well-appointed space for guests. This addition can transform the functionality of your home, making it more accommodating and enjoyable for everyone.


Add a Sunroom:

A sunroom offers a bright, relaxing space where you can enjoy the outdoors year-round. Think of floor-to-ceiling windows, comfortable seating, and a design that brings in natural light and scenic views.

This addition is typically done as a bump out, extending from your living room or kitchen into the garden, creating a perfect spot for morning coffee or evening relaxation. You can personalize your sunroom with features like skylights, ceiling fans, and climate control to ensure comfort in any season.

Add lush plants, cozy furniture, and a soothing color palette to create a serene atmosphere that feels like a true escape. A well-designed sunroom can become a favorite retreat for reading, entertaining, or simply enjoying the beauty of nature from the comfort of your home.

These rooms can serve as a dedicated drop zone for coats, shoes, and bags, making your daily routine more efficient.

Imagine skylights for natural light, built-in storage solutions, and a comfortable layout tailored to your specific needs. Add stylish finishes and personalized touches to create a unique and inviting retreat. This transformation not only adds square footage but also enhances your home's overall charm and usability.

What Additions Add the Most Value to a Home?

Some of the most common additions just so happen to also fetch a handsome return on investment (ROI). In some cases, you can count on an addition to deliver a great ROI, but it also depends on the specifics of your home. 

A home with too few bathrooms compared to bedrooms, a cramped kitchen, or one that lacks an outdoor living space will gain the most ROI with an addition or expansion when it comes to market value. Older homes tend to lack a primary suite, making this addition very valuable. Adding more livable square footage to your home with an attic conversion will also give you a sizable ROI. 

However, a great ROI isn't the only thing to consider when choosing the kind of addition or where to place it. If you plan to stay in your home for the foreseeable future, the addition you need to live comfortably or creating a space that brings joy is the most important consideration of all.
