There are many types of housing additions that can rejuvenize a home, and conventional house add-ons are the most popular option. These consist of upgrades such as kitchen expansion and adding a master bathroom to an existing bedroom.

Attic, Basement, Or Garage Conversions


Many people opt for these types of housing additions as their first step during a renovation. Since a core structure is already in place, less work has to go into this process, equating to a cheaper project overall. Homeowners typically use these housing add-ons for in-law suites or additional rooms.

Room Addition Or Bump-Out


A room addition or bump-out is built onto a part of the house to expand an existing room. Homeowners often choose this avenue to add a bathroom to a bedroom or meet zoning laws for converting an attic or garage into suitable living quarters.

These home expansions are detached from the home. They’re their own structure entirely, with their own electrical, plumbing, and HVAC equipment. They can be significantly more expensive than room additions to the existing as a result. But these types of housing additions make great art studios, in-law units, offices, or guest homes.

How Much Does It Cost to Add an Extra Room to Your House?

Average home expansion costs range from  $20,000 to $80,000. A handful of factors can alter this price, including the size of the expansion, the type of extension, building materials, and your home’s location.


Size & Type of Extension


There is a significant difference in price depending on the types of housing additions you choose. For example, constructing a small sunroom will cost significantly less than building larger housing add-ons like a master suite.

Contractors often charge by the square foot for labor and material costs. And the fee of required materials differs dramatically from project to project.




It’s vital to factor in your community when budgeting for any type of home addition. If you live in a city or suburban area, there are likely to be many qualified carpenters available at a reasonable price.

However, your city’s zoning fees, permits, and inspections will amount to a hefty price. Alternatively, those in rural communities may be subjected to call-out fees and transport costs, which can drastically increase as you move farther away from populated areas.


Is It Cheaper to Add On or Build Up?

Each project is unique. Whether it’s cheaper to complete a house add-on or a vertical build-up will depend on the following factors:

  • Time commitment
  • Material costs
  • Number of laborers needed
  • Location
  • Zoning permit costs

In most cases, a home expansion will most likely cost more. It usually requires digging, pouring concrete, and building the foundation.

When building up, your foundation is already there, which is generally less costly. Plus, it allows your home’s footprint to remain the same.

Those who have trouble deciding between a house add-on or a vertical build-up may want to consider adding a sunroom. Sunrooms are much more affordable than committing to a full-room addition.

Sunrooms are typically made from pre-fabricated materials, such as steel windows and thermally broken glass. Alternatively, they can be constructed with lumber, concrete, and other materials that provide a similar look and feel to the rest of the home.
