The latest round of mandatory gender pay reporting in the United Kingdom has delivered a mixed picture for the architecture sector — and a particularly unflattering one for Zaha Hadid Architects (ZHA). After reaching a record low median hourly pay gap of 6.3 percent in the previous cycle, the firm saw that figure more than double to 14.5 percent. For every pound earned by a middle-ranking man at the studio, a middle-ranking woman earns just 86 pence. The regression is notable not only for its scale but for its timing: it arrives as several rival practices report movement in the opposite direction.

Foster + Partners and Allford Hall Monaghan Morris both reported narrowing gaps this year. The divergence raises uncomfortable questions about what separates firms that are closing the disparity from those that are not — and whether the architecture profession's particular structure of advancement makes sustained progress inherently fragile.

A structural problem, not a pay-rate problem

ZHA's defense — that "women and men in equivalent roles are paid equally" and that compensation is "wholly factored on merit" — is a familiar refrain across knowledge-economy employers. It is also, in a narrow sense, likely accurate. The UK's gender pay gap reporting framework does not measure whether men and women in the same job title receive different salaries. It measures the distribution of men and women across pay quartiles within an organization. A firm can pay identically for identical roles and still post a wide gap if men dominate the upper quartiles.

This is precisely the pattern the ZHA data suggests. The firm's mean hourly pay gap — the average across all employees rather than the midpoint — has remained essentially frozen at 22 percent for three consecutive years. Stagnation at that level points to a durable structural imbalance: men continue to hold the vast majority of the most senior, highest-compensated positions. Meanwhile, the median figure, which is more sensitive to small shifts in personnel composition, has swung sharply from year to year, making it a less reliable indicator of underlying change.

The bonus gap reinforces the picture. Women's median bonuses trailed men's by nearly 34 percent, a disparity that typically reflects the same seniority skew, since performance-related pay in architecture practices tends to scale with project leadership responsibility.

The industry's wider reckoning

The UK's mandatory gender pay reporting regime, introduced in 2017 for employers with 250 or more staff, was designed to create exactly this kind of transparency. Architecture, as a profession, has long exhibited a well-documented attrition pattern: women enter the field in roughly equal numbers to men at the graduate level but leave — or plateau — at disproportionate rates before reaching senior design and leadership positions. Long project timelines, a studio culture that often rewards sustained physical presence, and informal mentorship networks that tend to replicate existing hierarchies have all been cited as contributing factors.

The fact that some firms are narrowing their gaps while others are not complicates any single-cause explanation. It also suggests that firm-level decisions — around promotion pipelines, flexible working, and the composition of leadership teams — matter at least as much as sector-wide dynamics. A practice that promotes several senior women in a given year can see its median gap shift substantially; one that loses a handful can see it widen just as fast. The volatility of ZHA's median figure across recent cycles may reflect precisely this sensitivity.

What the data cannot reveal is intent or trajectory. A widening gap in a single year does not necessarily indicate a deteriorating workplace for women; it may reflect hiring patterns, departures, or restructuring that temporarily distort the distribution. Equally, a narrowing gap at a competitor does not guarantee that the underlying culture has shifted. The numbers are a snapshot, not a verdict.

The tension at the core of this debate remains unresolved across the profession: whether meritocratic frameworks, applied within structures that were not designed with equity in mind, can produce equitable outcomes without deliberate structural intervention — or whether the architecture of the firms themselves needs redesigning before the architecture of pay can change.
