Highrise floorplate size.

[trust]

Couple questions for the experts:

1. What is the average floorplate size for a highrise ranging from 20-40 stories? I believe they are roughly 15,000 square feet although not 100% positive.

2. Are these floorplates typically square, or more rectangular in shape?

3. Lastly, I know some highrises done here are on lots with a very narrow frontage. What is considered a narrow frontage? 60 feet? And what is consider a typical size or "do-able"? 100 feet?

Much appreciated.

Thanks

Office or Residential???
There is a difference.
Office generally has a large floorplate.

Office - 25,000 sf plates are common and can be sqaure or rectangular. Usually depends on the layout of the site.

Residential - Less than 10,000 sf for most new buildings in the City. The City pushes for less than 8,000 sf as part of their tall building guidelines.

Narrow Sites - 60' is a very narrow site. I know of a couple that have been designed recently but I'm not sure if they were built. 60' is the wdith of a single parking module, so often the issue is getting multiple levels of parking below the structure without ramps.

Hope this helps.
