Frequently Asked Questions

Yes, you likely can transform your attic into a bedroom, but it requires proper finishing or remodeling first. To ensure it’s safe, comfortable, and compliant with building codes, it’s crucial to have it professionally assessed and updated. 

An attic renovation can add charming and functional living space to your home. If you’re interested in exploring this possibility, we recommend scheduling a consultation with experienced attic remodeling contractors in Portland who can guide you through the process.

Adding value to this space often depends on its functionality and how it complements your lifestyle. Common features include creating a multi-purpose family room, adding a home office, and/or designing a guest suite. We often see clients creating mixed-use spaces to maximize the area. High-quality finishes, good lighting, and moisture control are also key. However, the value of a basement renovation largely depends on your specific circumstances and what you’re hoping to gain with it.

The exact price varies widely depending on factors such as the size of the space, the structural modifications needed, the materials you choose, and the complexity of the new attic design. Insulation, ventilation, access, and many other considerations can also impact the cost. For a precise estimate, it’s best to get in touch with COOPER Design Build, leading experts in attic remodeling in Portland, and ask them for an assessment and a detailed cost breakdown.

Planning a basement renovation should always start with thinking carefully about what you would like to achieve with this project. Think about the purpose of the space – whether it will continue to be a storage area or if you’re transforming it into an entertainment room, an additional bedroom, or a home office.

Next, get in touch with a professional basement remodeler, like us, to assess structural requirements, moisture control, and insulation needs. A skilled team can help you design the space and handle all aspects of construction, ensuring a smooth transformation.
