Whittier Choice Neighborhood | 1158 Tremont Street | Roxbury

I am guessing the 8 stories above podium are cold-formed steel framing (hard to tell), potentially Type IIB construction which might allow for this. Interesting strategy whatever the case is.
 
It would be required to be of "noncombustible" materials for the most part. If I had to guess they utilized a prefabricated metal framing system (such as the late Presceint company) in which the wall panels are loading bearing. This is in Nashville, but the metal framing was utilized above a podium and they did 10 levels of load bearing steel studs.

The proportions of the red squares looks absolutely horrendous for some reason. If all of that was removed and you just had the grey facade underneath it appears like it would have looked fine. It comes across like at the last second they remembered that in boston we have a mandatory unwritten staggered windows requirement so they slapped this red stencil over top of the facade and called it good. If they wanted to add color they should have just made a couple of the vertical facade lines red instead, that would have come across much better.

Can anyone shed any light onto why this building is in the 10-12 storey range? I thought that was like, the worst of both worlds from a construction cost perspective.

It's "steps down" from the 22 stories at International Village to the 3 stories in the rest of the neighborhood and some urban designers really feel that is vitally important for some reason.

Theres not a ton of construction pics but if you go back a page it appears to be some type of prefab construction. They built it like a 5 over 1 only as an 8 over 2 with these prefab metal box sections that they stacked on each other above 2 CIP concrete floors. So it appears thats where the cost saving would come from. Instead of building an entire cast in place structure, or pouring a cast in place core and framing structural steel around it for 10 floors like you would a normal skyscraper, they built it as a prefab 8 over 2. Id imagine you cant go much taller then this with this type of prefab structure but for a 10 story tower this would be a lot cheaper than the other methods.

-I looked through the project documents and on Dimeo’s website and there wasnt really any information there but it looks very similar to other modular highrises that are going up around the world. Apparently the manhattan ac marriott was built this way and is the US’s tallest modular hotel at 26 stories.
