Most commercial spaces aren’t move-in ready. Tenant finishing — the construction work that adapts a space to a specific business — ranges from a bare shell to a fully furnished suite, and knowing where your project falls shapes your budget and timeline.
Madden Construction handles the full spectrum: white box, clean rooms, furniture set up, office furniture moving, and turn key delivery.
What Is Tenant Finishing?
Tenant finishing (or tenant improvement) turns a landlord’s base-condition space into a finished office — walls, flooring, ceilings, electrical, and HVAC built around how the business operates. A law firm, medical practice, and tech startup need very different layouts from the same shell.
White Box: The Starting Point
A white box, or “vanilla shell,” is brought to a basic, neutral condition but not yet built out. It typically includes paint-ready drywall, a drop ceiling grid, subfloor ready for finishes, electrical and HVAC distributed but not finished to rooms, and code-compliant restrooms with no interior partitions.
This gives tenants a clean starting point without paying for finishes they’d tear out. Madden Construction builds the interior layout — offices, conference rooms, workstations — from there. The term isn’t standardized, so confirm exactly what your landlord is delivering.
Clean Rooms: Controlled Environments
Medical offices, labs, dental practices, and some tech or manufacturing tenants need clean room construction — spaces built for strict air quality and contamination control. That means specialized HVAC with HEPA filtration, seamless non-porous surfaces, sealed joints and gasketed doors, and compliance with standards like ISO cleanliness classes or healthcare codes.
Clean rooms require tighter coordination between the contractor, mechanical engineers, and your compliance requirements. Madden Construction works directly with your vendors and regulators so the space passes inspection the first time.
Furniture Set Up
A built space isn’t functional until it’s furnished — workstations, seating, conference tables, storage, and reception furniture. Timing matters: furniture delivered too early gets damaged or blocks trades; too late, it delays move-in. Because Madden Construction manages both construction and furniture install, delivery is sequenced to arrive exactly when the space is ready.
Office Furniture Moving
Many projects are relocations or phased renovations, not new builds. Office furniture moving covers disassembly and reassembly of workstations and systems furniture, safe transport between locations or floors, phased moves that keep teams working, and reconfiguring existing furniture for a new layout. Handling this as part of the overall project — not a separate vendor — keeps the schedule tight and furniture undamaged.
Turn Key: One Contractor, One Schedule
A turn key project means Madden Construction manages design coordination, permitting, construction, furniture, and the final move under one contract. That means one accountable party, fewer scheduling conflicts between trades and vendors, faster overall delivery, and a single point of contact for issues and change orders. For owners without bandwidth to juggle multiple contracts, turn key is typically the fastest path from empty shell to move-in ready.
Choosing a Contractor
Look for experience with your specific space type, in-house furniture and moving capability, a clear process for coordinating with your landlord, an itemized timeline from permitting to final walkthrough, and references from similar recent projects.
Frequently Asked Questions
What’s the difference between white box and turn key?
White box is a starting condition — a basic shell. Turn key is a delivery model, where one contractor manages construction, furniture, and moving through to a finished, move-in-ready space. A project can start at white box and finish turn key.
How long does tenant finishing take?
A standard office buildout from white box typically runs 8 to 16 weeks including permitting. Clean rooms and larger or more complex spaces take longer. Furniture set up and moving are usually scheduled in the final 1 to 2 weeks.
Does my office need a clean room?
Only if you have medical, dental, lab, or manufacturing equipment with air quality or contamination requirements. Standard professional offices don’t need one. Madden Construction can confirm what your space requires.
Can one contractor handle construction, furniture, and the move?
Yes — that’s a turn key project. Madden Construction coordinates all three under a single schedule, so nothing falls through the gaps between vendors.
