Dormers transform unused attic space into full, livable square footage.
A dormer extends vertically from your existing roofline, allowing for:
- Increased ceiling height
- Additional bedrooms
- Expanded bathrooms
- Office or living space additions

Full dormers are one of the most popular renovation projects on Long Island due to lot size limitations and zoning regulations.
Every structure is engineered and built to meet Long Island building codes and your specific needs.
