Scale-up offices: Kytom method to absorb hyper-growth, frame m²/workstation ratios and deliver a scalable floor plate in 12 weeks on average.
"We're going from 50 to 200, we're overflowing"
A scale-up that runs out of space pays twice: rent for the current site plus overflow coworking at 450 euros excl. VAT per workstation per month. For 30 overflowing workstations over 8 months, the additional bill reaches 108,000 euros, not counting the coordination hours lost by the real estate department.
Below 8 m² per workstation, ambient noise exceeds 65 dB and reduces concentration by 22%. For an HR director in an intensive recruitment phase, turnover rises from 4 to 9 points when the physical environment hinders the integration of the last 50 arrivals.
Regulations require exits and sanitary facilities proportionate to headcount. Exceeding the declared public-access building capacity exposes you to a formal notice from the inspectorate, and the tertiary decree now requires a 40% energy reduction by 2030, hard to meet on an undersized site.
Kytom frames scale-up office design across three horizons: day 1 headcount, 12-month projection, maximum capacity at 24 months. Our 11 agencies have supported more than 1,200 clients since 2006, including a significant share of hyper-growth start-up offices between Series A and Series C. We combine a quantified usage diagnosis (occupancy measurement over 3 weeks), 3D modeling of density scenarios, and a works phasing compatible with your activity in an occupied site. The average area handled, 850 m², corresponds exactly to the pivot format of a scale-up of 80 to 150 people. Each deliverable includes a flex reserve of 15 to 20% to absorb unforeseen recruitments.
Occupancy audit over 15 days with presence sensors, interviews with the leader, HR director and workplace director, review of the recruitment business plan. Deliverable: a 12-page framing note with current m² per workstation ratio, target and quantified gap over 24 months.
Program workshop with 6 to 8 internal stakeholders to arbitrate ratios, space typologies and budget. Deliverable: detailed functional program, budget range to plus or minus 10%, and macro schedule integrating fundraising milestones.
Design in 3 scenarios (densify on site, additional floor, relocation). 2D plans, 3D views, furniture plan and firm cost estimate. Deliverable validated by the management committee within 4 weeks, with acoustic analysis and public-access building compliance integrated.
Turnkey works management, coordination of trades, furniture (Vitra, Herman Miller depending on arbitration) and relocation. Delivery in 12 weeks on average, acceptance in an occupied site by batches, 12-month defects liability warranty and 90-day post-delivery support.
"We doubled our headcount in 14 months without changing address. Kytom phased the works in 4 batches and we kept 100% of teams productive during the build."
From 60 employees if the trajectory anticipates a doubling within 18 months. Below 8 usable m² per workstation, the observed indicators show a measured deterioration in engagement and a 30% rise in acoustic complaints.
The decision rests on 3 criteria: the site's maximum capacity (public-access building ratio), the residual term of the lease and the local market cost per m². In general, densifying remains cost-effective up to 10 m² per workstation; beyond that, relocation becomes necessary.
For a scale-up, count 1 meeting seat per 4 workstations, of which 40% in rooms for 2 to 4 people (video, one to one). ARSEG measures that 65% of actual meetings involve fewer than 5 participants.
Measure the actual presence rate over 3 weeks before any calculation. Most scale-ups run at 65 to 75% average presence, which allows a ratio of 0.75 workstation per employee, with reinforced shared zones.
Count 850,000 to 1,400,000 euros excl. VAT for 850 m² fitted out, furniture included. The range depends on the finish level, the share of acoustic partitioning and furniture arbitrations (Vitra, Herman Miller or equivalents).
Yes, 85% of our scale-up projects take place in an occupied site, phased in batches of 200 to 300 m². Noisy disturbances are scheduled outside working hours, with a dedicated Kytom contact for daily coordination.
