Randy Alcorn discusses the topic of Heaven on the Janet Mefferd Show. March 2010.

I believe the New Jerusalem is right now in the present (intermediary) Heaven because of my understanding of Revelation 10.

The city’s exact dimensions are measured by an angel and reported to be 12,000 stadia, the equivalent of 1,400 miles or 2,200 kilometers, in length, width, and height (Revelation 21:15-16).
