Well, 'no-DIT', it's interesting you should ask that.
It could be called inflation but, as the architectural recruiting agencies apparently charge 15% of employees salaries, it isn't really increasing the costs.
The real shortage in the current boom is in skills, both among builders and professionals. With regard to architects, there is an apparent shortage of people with between six and say twelve years' experience - largely because these people qualified during a recession and a large proportion emigrated. The end result is questionable quality of design/workmanship on many projects under construction.
But the most important thing is money. It's about time people paid architects properly. Let's hear it for architects. A great bunch of fellas! Hurrah!
