It is a shameful that some practices and practitioners still live in the 1950's. You would think that their education alone would nullify such attitudes - or is just the herd mentality? Some of the best firms I worked with were those with a good male:female balance and just happened to be in London. These had an edge and a dynamic that made a studio feel vibrant. I am certain the architecture produced arose from this mix. Working in the provinces, as I do now, the balance and dynamic is difficult to achieve as the supply of women Architects appears to be significantly less in the sticks.
