121 East 22nd -- which is OMA's first ground-up project in Manhattan -- recently finished up construction at the corner of E 23rd St and Lexington Ave (the site continues through to E 22nd St, where there is basically a 2nd building). I wrote about the project over two years ago, here.
Below is a photo by Laurian Ghinitoiu, via Dezeen, of it completed:

The defining feature is its "prismatic corner", which, I understand from this interview with David Von Spreckelsen (President of Toll Brothers City Living), was largely an outcome of the site's restrictive zoning. There was a requirement to have constant street walls. That minimized what could be done architecturally on the project's main elevations.
The solution is two contextual street walls -- the punched windows are designed to match the rhythm of their adjoining buildings -- coming together and creating dramatic visual interest only at the point where they intersect. Below is a rolled out elevation from OMA. Note the gradient created by the windows as they converge toward the corner (center in the drawing below).

The other interesting thing about this project is that it reminded me just how different the built form of Manhattan can be compared to Toronto. In the case of 121 East 22nd, the streetwalls rise 150 feet without any stepbacks. There is then a 10 foot stepback before the building rises another 60 feet -- similarly without any additional breaks.
I love the grandeur.

London is currently running a 12-month pilot on its first ever 3D zebra crossing. The objective is to improve pedestrian safety by making the crossing more visible to drivers. A 3D zebra crossing stands out by appearing to float above the road.
Here's a photo (image credit to Gusti Productions):

While this is the first of its kind in the UK, similar crossings have already been installed in Iceland, India, Taiwan, and other countries. According to the trials in India, they do appear to have a meaningful impact on vehicular speeds. They also feel like public art.
If this first one proves to be successful, the plan is to roll out these 3D crossings across the entire borough of Westminster. Assuming they do actually work, I'm surprised there hasn't been more noise around them here in Toronto.
A London-based software company is also working to completely rethink the zebra crossing for today's smartphone world. Their system imagines LEDs embedded into the street so that a crosswalk can be triggered basically anywhere.
Perhaps this is something that might work with the street paving that Sidewalk Toronto is piloting.

This is not exactly a new project. The hotel, pictured above, opened in 2016 and was the brand’s second location (their first opened in São Paulo in 2001). But I like the story and how it was executed.
Hotel Emiliano is the work of husband and wife team Gustavo Filgueiras and Andrea Colli Filgueiras. He is a hotelier. And she is a jewelry designer. Both wanted to pay homage to the glory days of Rio’s Copacabana Beach.
Designed by Arthus Casas and Chad Oppenheim – who, by the way, recently built himself a stunning home in the Bahamas – the 90-room hotel is clad in white shutters that can be used to modulate the Brazilian sun.

On the roof is an infinity pool with a glazed side. Here is a screen grab from the hotel’s website:

And here is an aerial view of the pool taken from Dezeen:

The uniforms for the hotel were designed by Barbara Casasola and a custom jewelry collection was created by Andrea Colli.
