The Average Cost of a Loft Conversion

A loft conversion typically involves remodeling an unfinished attic space in a home into a variety of uses such as an extra bedroom, a separate apartment for older children or renters, or extra storage. Loft conversion construction costs vary widely on the uses of the space, materials and complexity.

Average Costs

In general, remodeling an attic into a bedroom can cost between $40,000 and $90,000. According to Hanley Wood, a real estate media company, the 2008-2009 national average cost to build an attic bedroom in the U.S. was $48,393. This was for a mid-range remodeling, including converting an unfinished attic space into a 225-square foot bedroom, with a small bathroom, windows, closet space, carpeting and other features.

Components

According to Remodel or Move, the most costly parts of an attic remodel will be a structural reinforcement if needed, structural renovations to provide access to the attic (such as a new stairway), carpentry, drywall, plumbing, electrical installation, materials and labor.

Considerations

According to the U.S. Energy Information Administration, the average loft in the U.S. is between 600 square and 900 square feet, and there is typically limited living space. Hanley Wood reported that the average U.S. attic bedroom remodeling in 2008 and 2009 achieved a resale value of $35,694, about 74 percent of the $48,398 project cost.
