Why Get a Secon-Story Addition
Adding a second-story ADU is a smart way to increase your living space without expanding your home's footprint. This is especially helpful in urban areas like Los Angeles, where land is limited and property sizes can restrict outward growth.
We create additional, private living areas that can serve multiple purposes. Whether you want a rental unit, a workspace, or extra family quarters, a second-story ADU offers flexibility without sacrificing yard space.

Key benefits include:
- Efficient use of limited land
- Increased privacy for occupants
- Minimal impact on outdoor living spaces
- Potential for rental income or multi-generational housing
- Streamlined permitting and construction on existing foundations
