Reside in "Poqr/Central" Yerevan ... only for the rich $$$
Sure there is North(ern) Avenue, which includes more than a dozen new residential buildings, but there is also the Main Avenue project, which will probably include another dozen or more new buildings, plus all the other new buildings being built around the city.
Right now, I can think of about 40 or more new residential buildings going up right in the center. (Imagine, 40 buildings, 8 floors each and 4 apartments/floor = almost 1,300 new apartments. This is a big underestimate, considering many of these buildings are double in size... 16 floors + 8 apartments/floor.)
Most locals seeking new apartments can't even bother looking into these places, which cost anywhere from $650-1,000/square meter (on North Avenue ($1,400+++) ... UNFINISHED ... meaning you have to paint; do the floors; install all the inside doors; kitchen appliances and cabinets; washroom sinks, showers and toilets; etc. Apartments are between 90-160 square meters (and sometimes more.) Ultimately, a one bedroom 90 square meter finished apartment (not furnished) will cost over $70,000, and believe me, 90 square meter apartments are rare in these buildings. The majority start from 140 square meters.
According to the people at Elite Group Real Estate, almost all of the apartments in the 5 or 6 buildings they are currently building are sold out, mostly purchased by Russian-Armenians.
The first pic is an unusual looking business building being built close to Congress Hotel on Khorenatsi; this second one is one of my most favourite new buildings, which is being built on Main Avenue right next to Charentz's Museum on Mashtots.
