I have changed my thinking on the preservation of sf lots in metro Vancouver. I don't think affordability is ever coming back for this housing type.

I live in a sf detached house in Richmond, an area which is seeing 30-40 year old housing stock bulldozed and replaced with large luxury homes.  Lots sell for just under two million, and then add on the cost of the new build.

Many of these huge houses are either never occupied, occupied only part of the year, or occupied by only a handful of people.  No trees, no gardens, paved front yards with only a token amount of landscaping.

I would much rather see more affordable row housing or  townhouses replace it.
