Developer White Box: Keep, Rework, or Replace

Developer White Box is pre-finish: walls and floor are prepared, utilities partly routed, but there is no final layer yet. The format can shorten renovation time but does not guarantee quality for your scenario. Before finishing, audit what to keep, demolish, or reinforce. In a typical 60 m² apartment, common rework includes electrical, bathroom waterproofing, and adjusting locations for furniture and appliances.

What White Box means in practice

Developers use the term differently. In the contract and specification, look for a concrete scope, not a marketing label.

Element	Often included	What to check
Walls	Plaster or drywall ready for paint	Flatness, 90° corners, cracks, drying
Floor	Cement screed	Level deviations, voids, moisture, strength
Ceiling	Unfinished or basic prep	Height, levelness, light fixture provisions
Electrical	Panel, some outlets and drops	Circuits, wire gauge, RCD, load match
Plumbing	Drops for fixtures	Diameters, pressure, slopes, access to inspection points
Doors	Sometimes entrance and interior	Opening geometry, door leaf quality
Windows	Usually from developer	Separate from White Box, but must be checked

Compare White Box with rough and turnkey in Rough, White Box, or Turnkey. New-build context: renovation in a new building.

What you can keep

Keep only what passes inspection and matches the project.

Walls

If flatness is within tolerance for your finish (paint, wallpaper, tile on prepared zones), there are no cracks, and primer holds — developer plaster can stay. Refine corners and reveals locally.

Floor screed

Keep it when level deviation is within the flooring manufacturer's requirements, with no crunch or delamination. Self-leveling floors and large-format tile need tighter tolerances.

Entrance door

If sound insulation, locks, and appearance are acceptable, replacement is optional. Still verify openings for interior doors.

Radiators

If heating matches the project and appearance is acceptable, they can stay until finishing. For concealed routing or non-standard solutions, agree in advance.

What to rework or reinforce

Electrical

Typical developer wiring rarely matches your kitchen, appliances, lighting scenarios, and charging zones. Common reasons for rework:

• insufficient circuits and lines;
• outlets in the wrong place for furniture and appliances;
• weak panel without proper protection;
• no drops for exhaust, AC, underfloor heating.

Rework is cheaper before finishing, while walls are not closed.

Waterproofing and bathrooms

Wet areas are high risk. Check:

• full floor and shower-wall waterproofing;
• correct slopes;
• accessible inspection points;
• drops match the plumbing plan.

If the developer did "minimum for handover," rework is often justified.

Walls under heavy tile and furniture

Kitchen backsplashes, TV panels, and wall cabinets need strength and flatness checks. Weak prep leads to tile failure and fixing problems.

Ventilation

Confirm ducts are not sealed, draft is adequate, and exhaust locations match kitchen and bathroom plans. Otherwise tile and ceilings must be opened later.

Sound insulation

White Box rarely includes proper floor and wall acoustic layers. If comfort matters, plan a separate layer before finishing.

Steps after receiving White Box

1. Handover with a report (if not yet signed).
2. Technical audit — measurements, moisture meter, electrical and bathroom checks.
3. Project alignment — outlets, lighting, plumbing, furniture locations.
4. Decision per layer — keep / refine / demolish.
5. Staged estimate for rework and finishing.
6. Finishing only after MEP and substrate issues are closed.

White Box inspection checklist

Zone	Check	Red flag
Walls	2 m rule, corners, cracks	Wave beyond wallpaper/paint tolerance
Floor	Level, moisture	Beyond flooring tolerance, damp substrate
Electrical	Panel, circuits, grounding	No RCD, thin wire, one circuit for everything
Bathroom	Waterproofing, slopes, drops	No insulation, wrong locations
Openings	Door sizes	Out of square, no adjustment margin
Ventilation	Duct passage	Sealed ducts, weak draft
Windows	Sealing, reveals	Drafts, condensation

Common mistakes

Mistake	Result
Trusting the "White Box" label without inspection	Rework during finishing
Starting tile and paint without electrical audit	Chasing finished walls
Ignoring screed moisture	Floor blisters, mold
Skipping bathroom waterproofing	Leaks to neighbors
No location plan	Outlets behind kitchen, wrong lighting
Comparing estimates only by price per m²	Hidden demolition and extras

Questions to ask the contractor

1. What do you keep from developer finish and what do you remove — and by what criteria?
2. How do you audit White Box before the estimate?
3. What tolerances for walls and floor do you use for our finish?
4. Do we need electrical rework in our case and at what stage?
5. How do you handle extras if developer defects appear during opening?
6. What is the timeline including rework, not only finishing?
7. Do you take photos of concealed layers after bathroom and electrical rework?

What Profmaster can check

• White Box audit after handover: walls, floor, electrical, bathrooms, ventilation.
• Alignment with your living plan — outlets, lighting, plumbing, furniture.
• Layer recommendations: keep, refine, rework.
• Staged estimate for rework and finishing without end-of-project surprises.
• Rework acceptance against a checklist before starting the final layer.
