Russia has a rich vernacular and classical scene with both creative heights and pastiche. Most but not all interesting projects are in the twin capitals Moscow and Sankt Petersburg. What is interesting is the ongoing experimentation with the classical tradition thus trying to move it forward. Many projects take inspiration from Art Nouveau, a style that seems especially loved in the country.
Ukraine has a lot of classical inspired projects but few truly classically trained architects. While there are good projects, one problem is that developers are allowed to add to many floors to projects thus distorting the classical proportions.
