What Is an Interior Fit-Out—and Why Does Your Business Need One?
An interior fit-out involves completing or renovating the interior of a commercial or industrial building to make it functional, efficient, and habitable. Whether you’re finishing a newly built shell or refurbishing an older space, a fit-out transforms empty or outdated interiors into productive, brand-aligned environments.
Typical interior fit-out elements include:
- Framing and partitioning – Dividing offices, retail, or service areas
- HVAC installation – Room-appropriate heating, ventilation, and air conditioning
- Electrical and plumbing – Lighting, outlets, and fixtures
- Ceilings and floors – Suspended ceilings, acoustic tiles, resilient flooring
- Wall and surface treatments – Paint, drywall, paneling, or specialty coatings
- Custom millwork – Reception desks, cabinetry, shelving, and service counters
- ADA compliance – Accessible pathways, restrooms, and fixtures
- Fire integration – Sprinklers, exit signs, alarms, and life safety systems
Each project is tailored to your business’s needs and location-specific code requirements.
Knollmeyer fully complies with the Massachusetts State Building Code (780 CMR), delivering safe, functional interiors designed to help your business thrive.
