When I was referring to the earliest skyscrapers what I had in mind was the 10 story Home Insurance Building in Chicago (1885) or the 10 story Wainwright Building (1891) in St. Louis, which may be considered true skyscrapers because they had elevators to transport people to the higher floors.

We have lost a number of fine buildings in Liverpool but I think that Oriel Chambers is safe and that its importance in the development of building technology is now recognised. In fact, it has recently been refurbished and is considered quite a prestige address.

Benson Industries from Portland Oregon.

Who is they?

Good progress on 1WTC

Gooderham building in Toronto was well before the Flat Iron.

Yes, except for one building over 100m (that I know of) in the world that has no load on the outside of the building:

Oops double post

Ehhh. I wish they would have just rebuilt the original twin towers. I think the new 1wtc looks good, but I like the original way more.

What you describe is a "tree" structure. Although I have seen many on paper, including a mile high tower designed by Frank Lloyd Wright, I have seen very few actually built.

The problem is, like trees, they sway far too much in the wind. They just aren't rigid enough.

Tower One is a "tube/tree hybrid" the core being the tree part and the tube is the perimeter, also called "Wind Frames" consisting of the columns and spandrel beams with moment connections at all beam to column connections.

The Twins were a "Tube" structure. The Sears Tower is a "Bundled Tube" design.

I wonder why the slow down on the cladding? Maybe they weren't happy with the alignment?

this building rocks! and i have to say its quite an improvement to the old world trade centres which were quite boring... although they were a great symbol of economic power when it came down to the looks of them they were quite drab...this is a step on the right direction. i wish they hadn't come down the way they did though :'(

This tower is looking real good now...

I love how New York is going to beat Taipei at its own game by having a huge spire, like when it passed the Sears Tower and Twins by putting up a decorative spire. Eat it

you mean the petronas towers? Taipei 101 beats them both by roof height as well as pinnacle height.

I think he means the original WTC twins....

Yeah, I know about the mile hight tower..I was reading about it in the Wright's books...Gotta say this "tree" structure is really interesting and challenging...I saw a few proposals on this forum too...I hope we'll see more of it in the future...
