Architectural identity: creating consistency between image and use

Every office architectural identity is built on resolving 3 pairs of opposing constraints:

• Distinctiveness versus urban integration: the architecture expresses the occupant’s personality while respecting the volumes, materials and rhythms of the surrounding built context.
• Brand expression versus flexibility of use: visual codes must support 2 to 3 major reconfigurations over an average occupancy cycle of 9 to 12 years.
• Visual impact versus energy performance: choices of glazing, thermal inertia and solar shading determine consumption over 30 years, within a regulatory framework setting reduction targets per decade at the 2030, 2040 and 2050 deadlines, in relative or absolute value (CSTB).

The prioritisation depends on the occupancy profile. A single-tenant headquarters favours a strong signature, noble material, identifiable architectural gesture. A multi-tenant building favours adaptability of the fit-out, with floor areas per tenant generally between 500 and 1,500 m² depending on the asset’s positioning. A mixed-use building (offices, services, catering) combines a shared programmatic base with differentiated floors.

When this strong-signature approach does not apply: on rental floors below 600 m² intended for rapid tenant turnover (standard 3-6-9 lease, successive multiple tenants), an identifiable architectural approach is counterproductive. The cost of neutralisation at each turnover exceeds the perceived value, and a neutral, modular and reconfigurable architectural vocabulary again becomes the rational choice. The identity signature finds its return on investment from 1,200 m² single-tenant or on firm leases longer than 9 years.

Kytom’s position, running counter to part of the profession’s conventional wisdom: the architectural signature is not a universal good. A significant share of office programmes would benefit from embracing a claimed neutrality rather than a forced identity. Neutral-approach operations tend to generate lower rental reinstatement costs than strong-identity operations, a trade-off that asset management departments increasingly factor into their selection criteria. Strong identity is an investment, not a standard.

For the asset management department and the asset manager: where identity creates or destroys asset value

The identity question reframes itself in financial terms. On an office asset held directly or via a property company, 3 parameters drive the trade-off: holding period, tenant profile (single or multi), resale liquidity.

• Long holding + single-tenant + firm lease over 9 years: the architectural signature reinforces use value and the signature premium at resale. The initial extra cost is amortised over the headline rent differential and tenant stability.
• Short holding + multi-tenant + 3-6-9 turnover: the signature destroys value. Each turnover triggers a neutralisation cost (removal of signature elements, reinstatement for the next tenant) that weighs on net cash flow. The tertiary regulation also imposes an energy trajectory that takes precedence over aesthetic choices in CAPEX trade-offs.
• Mixed-use asset with a services base: the design approach focuses on the shared base (lobby, catering, shared services) and frees the rental floors from a constraining signature.

The Kytom reading: identity consistency is an asset management decision before being an aesthetic one. The recurring mistake is to leave the matter to the project team alone, without framing from the owner on target holding period and leasing strategy.

3 recurring mistakes: catalogue effect, rigidity, neglected interfaces

Kytom’s experience feedback, accumulated since 2006, highlights 3 pitfalls that compromise identity consistency:

1. The catalogue effect: multiplying stylistic references without a guiding thread produces a blurred identity, complex maintenance and asset management costs significantly higher than projects built around clear invariants.
2. Programmatic rigidity: designing overly specialised spaces (fixed auditorium, heavy masonry partitioning) limits reconfigurations and blocks organisational evolution over 5 to 7 years, a horizon that our experience feedback since 2006 confirms as critical.
3. Neglect of interfaces: underestimating the transitions between public, semi-public and private spaces creates breaks in use and degrades the readability of circulation routes.

The safeguard lies in an approach based on invariants: defining 2 to 3 strong identity elements (signature material, recurring geometry, lighting treatment calibrated to the illuminance levels required by use) deployed flexibly according to functions. The invariants are documented in a set of architectural specifications issued at the end of the study phase, enforceable during subsequent fit-outs and transmissible to successive tenants in the event of a sale.

Kytom method in 4 steps and adoption ratios

Developing the identity follows a 4-phase sequence. The behavioural audit (2 to 3 weeks) maps current and target practices. The architectural approach (3 to 4 weeks) translates values into spatial principles, formalised by a physical model at 1/100 scale. The programmatic deployment adapts the approach to functions (reception, collaboration, concentration) via guide plans by typology. The interface prototyping tests transitions and circulation routes on a 1/1 mock-up in a pilot zone.

The usable floor area ratio per workstation commonly stands between 8 and 12 m² in open-plan and between 12 and 18 m² in an individual or enclosed office. Physical and digital modelling significantly reduces modifications during the construction phase, limiting change orders and their associated extra costs. Post-delivery feedback consolidated across the 11 agencies in France and Spain shows an adoption period of 3 to 6 months.
