“We renovated our home in Sherman Oaks and the project was handled very professionally. Drew kept everything organized and on track from start to finish. The job site ran efficiently and communication was clear. Foundational Builders made it easy.”

Common questions
- One. Design fees roll into the construction contract once plans are approved, so you only write checks to one team.
- Typical single-family remodel: 6–10 weeks from kickoff to permit submittal.
- We'll review them free of charge and either build to them or flag anything that'll cause permitting or budget pain.
