We're planning to extend and renovate our 100-year-old house, and all the plans that make sense involve removing an enormous poplar tree. The prospect makes me want to cry, as the tree is probably 100-150 years old and healthy and straight, but it's either remove the tree or abandon our plans.

It occurred to me that a possible consolation would be to have the tree milled into lumber and used to build the extension. This seems more environmentally conscious and less wasteful than simply chopping it up for firewood. But is it practical? Is it cost effective? What is poplar wood suitable for: framing, flooring, doors, paneling, cabinetry, trim, etc.? Any recommendations for arborists and lumber mills in the Northern New Jersey area?

Any help or advice would be appreciated.
