Some Examples of Popular House Addition Cost

There are plenty of spaces that you could add into your house as a house addition but there are three additions that are very popular. Adding an addition is one of the most creative ways to maximize the space in your place.

1. Single Storey Addition

Although this type of addition only takes up one storey, the end result is always the best one. You can get creative if you truly want the best result for this addition in order to maximize your space without making it look crowded when you have people in your place. In addition to that, the right choice of materials and design is a big impact too. This type of addition usually costs between $46,000 and $54,000 depending on the materials, design and the cost of labor.

2. Double Storey Addition

This type of addition became very popular because it truly maximizes your place creating more rooms for your house. Although this type of addition may be a major undertaking, the outcome can be amazing. The cost for this type of addition is between $55,000 and $68,000. The cost may still vary depending on your preferred design, materials used, and the labor.

3. Garage Conversion

This type of conversion became very famous because it allows a new space to surface without losing any part of your yard. However, it also has limitations on what kind of room it will be used for and depends on which part of the house it is located. The cost of an addition of this type is around $10,000 and $50,000 though the price will still depend on what type of room will it be, the type of your property, the materials that will be used and of course the cost of labor.

Cost of Addition per Square Foot

The cost of an addition mostly depends on the size of the room. Below is the average cost per square foot of a room.

Square Footage of Room Average Total Cost
20×20 $32,000 – $80,000
12×12 $11,520 – $28,800
10×12 $9,600 – $24,000
400 $32,000 – $80,000

600 $48,000 – $120,000
1,000 $80,000 – $200,000

Things to Consider in House Additions

Upon building the addition the home owners are required to have the approval of their local government (usually city or, in unincorporated areas, county building agencies) and the requirements for this are structural integrity, fire safety, energy efficiency, damp proofing, ventilation and other aspects of the building codes. Another thing to consider is knowing how big your addition will be. Next is finding the best designer that will meet your expectations. And, finally, you need to consider what will be the consequences of having a construction project on your property, for instance your neighbor’s take on the noise that comes from your place.
