How Much Does a New Addition Cost?

What does it cost to add on to your home? That’s not an easy question to answer. It depends on a number of factors and on whatever extras you want to incorporate into your home. 

The Full Addition Starts With the Foundation

A full addition includes some type of foundation with or without ground beams. The ground beams can hold your addition in place when tornadoes hit. With the way that Oklahoma soil is, a strong slab foundation is necessary. If you are one of the rare homes in this state that has a basement, you will need to dig a basement for the addition before you begin construction above ground. The slab, ground beams, etc., typically add to the final cost of the addition by several thousands of dollars. Square footage price for concrete is the biggest reason for this price.

Size of the Addition

Is it one story, two stories, or three? In most cases it is one or two stories. A second story doubles the price of building a first story because you will have to pay for supports and materials to make it durable. Total square footage of the new addition is usually priced by the footage.

The going rate is based on current market materials for construction and the costs of labor. At any rate you are looking at tens of thousands to over a hundred thousand dollars or more. Sometimes the cost of building an addition is greater than just building another home.

Base Price to Maximum Price

You want to get a ballpark figure for an addition. Start around $70,000 and go as high as a million. Most of the average-sized middle-class homes in this state have additions built on the lower end of that spectrum. Be prepared for variations in estimates.
