A home addition is a good investment because it increases your home’s resale value while increasing your usable space. Whatever the reasons for your need for extra space, there are several home addition ideas to help you gather insights to start your next home improvement project. Read on. 

Kitchen Additions

A big kitchen is a great way of increasing the house’s sale value. You can undertake a bump-out addition by cutting down an exterior wall or building an outdoor kitchen on a deck or patio. Other kitchen home addition includes a completely new kitchen or converting the existing small kitchen into a pantry or a small room for dining. 

Kitchen home addition is one of the cost-intensive home renovation projects because of the cost of plumbing, additional appliances, and new countertops. This should cost you somewhere between $6000 to $20,000. 

Bathroom Additions

Similar to kitchens, bathroom additions can be expensive because of the plumbing, countertops, floors and electricity costs. Bathroom home addition design ideas can include a new bathroom or expand an existing one. 

Having a bigger bathroom is beneficial for large families. Adding a small halfbath or water closet in the space under your stairs can also become another alternative. Revamping your small master bathroom can allow you to accommodate a soaking tub or a large vanity with two sinks. 

Furthermore, one of the convenient small home addition ideas is transforming your unused closet into half-bathroom for your guests.

This type of home addition plans ideas can add add a substantial square footage to your home and nearly doubles your home’s value when it’s time to sell.

When you embark on this addition, make sure to hire a remodeling company to help you with your plans, designs and advise you with any structural alteration. 

Extra Dining Room

If other relatives will be coming over to your house, there’s a chance that your current dining room won’t be enough. That said, it’ll be worthwhile for you to get a dining room addition. This is perfect for large family gathering during special occasions like Thanksgiving, Christmas, or a Pre-wedding celebration.

Here are some of the things we can include for your dining room addition:

  • New flooring
  • Pendant lighting
  • Dining table and chairs
  • Windows


This is a good home addition during mild weather. A glass enclosed space that functions like your living room is perfect for cool season. Natural light can come in and illuminate the space, adding coziness and warmth to your sunroom.

Here are the kinds of sunrooms for you to choose from:

Sunroom or Solarium

This is a glass-enclosed living room space that it attached to your house. You have a door inside the house to access your sunroom. This room type is not hooked up to the air ventilation system of your house, so during summer or winter, it will feel uncomfortable there.

Four Season Room

This one is like a sunroom but it has an air conditioning and heating system. This can be used as a living room extension for all seasons. You can add ornamental plants, sofa, and other upholstered furniture to add comfort to this home addition.


This is like the sunroom but with a mesh screen to cover the space. It allows fresh air to come in and out, so it’s most suitable during Spring and Summer. 

Garage Additions

Most garage doesn’t have a second story, you can create an extra space for your family’s need over your garage. This is a perfect location to add a guest bedroom and bathroom. They will be able to enjoy their own privacy while in your home. The space over your garage can also be a great place to add an teenager suite or an in-law suite.

Creating a studio apartment with a bathroom and small kitchen, and rent the place can help generate a source of income. Likewise, you can use it for paying storage unit across your town. 

Before taking on your home addition plans, make sure to check with your builder if the foundation and structure of your garage can support the weight of a second floor.  

Master Suite Additions

Besides your master suite, you can add another one, and allocate that when your in-laws visit. This is one of the best home addition ideas we have done for our clients. Below are some of the things included for this home addition:

  • Walk-in closet
  • Large bedroom

Adding a home office would also be great, especially if you’re on a work-from-home set-up. The two best places to have that will be in your attic or basement. But you can also let your remodeling contractor build it outside of your house, if this is the most feasible option.
