SECOND FLOOR ADDITIONS
Full Story vs. Dormer vs. Attic Conversion
Expanding your home’s living space can significantly enhance its functionality, aesthetic appeal, and overall value. When considering second-floor additions, homeowners typically have three main options: Full Story Additions, Dormer Additions, and Attic Conversions. Each offers unique benefits and challenges. Let’s delve into each to help you make an informed decision.

- Expanding Primary Suites: Creating spacious master suites.
- Maximizing Space: Especially on smaller lots where expanding outward isn’t an option.

Key Considerations:

DORMER ADDITIONS
Dormer additions extend a portion of the roof to create additional headroom and usable space within the attic. They are perfect for adding bedrooms or bathrooms, resolving egress issues, and enhancing upper-floor functionality.
