Unless the house is being designed with a more modern or loft-type feel, I would just go with a standard wood railing. 

@Jay HinrichsThis is very generous of you for giving back to the society, although you technically disqualified all out of state investors :).Thanks again for your generosity and ecnouragement to all new invstors to which I count myself as part of..you cluld have sold the property and given the proceeds to charity but you chose this route to encourage the community...This singular is most appreciated.....Merry Christmas!

We are debating doing it in an 80 yr old SFH that we are taking down to the studs and giving it a very modern aesthetic. 

One is  in North Tacoma and looks turnkey.The others are occupied but at the right price and modern enough that they need little work once empty.

We added 800 SF and updated all electrical and plumbing and completely renovated with contemporary elements typically not found in historic neighborhoods, such as open floor plan, large closets and master suites (both up and down) and gave the house a modern aesthetic. 

While I won't defend him on run down rentals I think it is unfortunate that society wants to hold him responsible for vacant properties and drug trade which he did not create.

However, you reach a point where you start paying a premium for the installation, as roofers have to use jacks & tethers to stay on the roof.Since a good quality, well installed flat roof system - even those installed 20-years ago - should have had a usable lifespan of 20-years (modern systems, well installed, should be expected to last 30 - 40 years), I would seek a new roofer.  

Adds a good modern touch

In addition, the absolute hottest trend in housing is modern houses.

Real estate is a necessity for society, it is not a luxury item, (can be) but in fills a basic human needs.
