Cross-cutting topics

Furniture, large open floors, hidden costs: three cross-cutting levers that determine the real success of an office fit-out project.

These three guides share the same logic: avoiding decisions taken too late, on false assumptions or on biased comparisons. Furniture shapes the daily posture of 100% of employees, the large open floor structures internal flows, and hidden costs (HVAC engineering, low-current systems, acoustic corrections) account for 8 to 15% of the overall budget. Kytom brings a senior perspective: we cost the trade-offs before signing, we compare the Vitra, Herman Miller or equivalent European ranges on their 7-year TCO, and we frame zoning by measured usage, not by generic standards. The objective remains constant: aligning the investment decision, real comfort and the tertiary decree trajectory.

Frequently asked questions about this category

Which guide should you start with?

If your project is at the budget framing stage, start with the guide on hidden costs: it avoids 80% of later unpleasant surprises. If you are working on a floor larger than 1500 m², the large open floor guide structures zoning first. The furniture guide ideally comes in after usage has been defined, that is 6 to 8 weeks before delivery, never before.

Is signature furniture always worthwhile?

Not systematically. For an operational workstation used 1800 hours per year, a Vitra or Herman Miller chair at 1100 €, amortised over 10 years, comes to 0.06 €/hour, compared with 0.09 € for an entry-level model replaced every 4 years. The calculation reverses for touchdown workstations. Our guide details the thresholds by workstation type.

How do you avoid the warehouse feel on a large open floor?

Three levers documented by ANACT: breaking the space into clusters of 8 to 12 people, varying perceived ceiling heights (suspended light fittings, 1.80 m planted partitions), and creating distinct visual landmarks for each zone. On 3000 m², plan for 4 to 6 differentiated atmospheres. The large open floor guide provides the precise ratios and the associated acoustic references.

What are the most common hidden costs?

The five most underestimated line items according to our 1200+ projects: HVAC adjustments for densification (3 to 6% of the budget), additional low-current systems (2 to 4%), post-delivery acoustic treatment (1 to 3%), removal and recycling of old furniture (1 to 2%), and health and safety coordination on occupied-site operations. The dedicated guide offers a schematic design checklist to factor them in from the initial costing.
