Hawkins\Brown has emerged as the only one of the UK's largest architecture practices with a gender pay gap better than the country average.
Collectively the 14 architecture practices that have reported data have a median gender pay gap – the common way of reporting pay disparity – of 18.4 per cent. This compares to the countrywide average of 9.7 per cent.
But Hawkins\Brown reported a pay gap of 2.6 per cent.
Foster + Partners reported a pay gap of 10.5 per cent last month, while Zaha Hadid Architects recently reported paying female staff 19.6 per cent less than men.
Pay gaps range from 2.6 per cent to 31 per cent
From tomorrow, the UK government requires all organisations with 250 or more employees to publish gender pay gap data annually.
Overall Dezeen found 14 architecture firms that have now reported their gender-pay disparity figures through the governmental portal. The median pay-gap figures range from 2.6 per cent to 31 per cent.
Along with Foster + Partners, Zaha Hadid Architects and Hawkins\Brown, other major practices to report figures include Allford Hall Monaghan Morris (AHMM) and Allies and Morrison.
Zaha Hadid Architects pays its female staff 19.6 per cent less than men, bringing the practice out in the middle of the list. Women make up 40 per cent of the overall workforce and 35 per cent of senior management at the London-based firm.
At Allies and Morrison and Foster + Partners, women are paid a median hourly rate that is 10.5 per cent less than male employees, while at AHMM there is a gap of 12.3 per cent.
NPS Group comes out bottom of the list with a median hourly rate disparity of 31 per cent.
Dezeen understands another practice, AHR, has a staff of 400. We have contacted the office for its gender pay gap figures.
Calculator helps practices calculate pay gap
As part of our Move the Needle initiative to tackle gender equality in architecture and design we've created an online calculator to help practices calculate how differently they pay male and female employees.
The tool calculates the percentage difference between the mean average salary of a firm's female and male staff – one of the two key metrics requested by the UK government to identify the gender pay gap. The second figure, the median, compares the wage of the middle male and female earner.
