Building Out... and Forward

Conversion an Attic Space into Something Functional

An attic conversion is the process of transforming an unused or underutilized attic space into a functional and livable area, such as a bedroom, office, or storage space. This often involves adding stairs, insulation, electrical and plumbing systems, and windows to make the space comfortable and usable.

Cost of an Attic Conversion

The cost of an attic conversion depends on a variety of factors, including the size of the attic space, the complexity of the job, and any additional features required. The cost can range from $35,000 for a basic attic conversion to over $100,000 for a more complex job. This cost typically includes all the necessary materials, labour, and permits needed to complete the job. It is important to remember that the cost can vary depending on the size of the project and any special features that may be required. Additionally, the cost of any additional features, such as Velux windows, skylights, and insulation, should also be taken into consideration when budgeting for the project.
