NEW YORK | 540 West 21st Street | 250 FT | 20 FLOORS

Is there any news, renderings, or info regarding the Architectural design?
I have not seen much in that regard…

This job site is now humming with activity: construction workers, materials, and equipment all coming together on this newly expanded job site.

I say expanded because they have now moved the construction barrier out to cover half of 21street. The work site looks a lot more spacious now.

The site now suddenly seems dormant; being this photo was taken during weekday afternoon. I doubt this project has stalled: this is most likely the ‘quiet before the storm’.

One thing for sure, no views (or few views) are forever in NYC. Take a look at all the windows facing the lot line. Those residential apartments all have very good waterfront views looking over the Hudson River; all looking north the toward the GWB and beyond.

On another random observation. I noticed most of those windows are NO MULLION windows: which is growing in popularity lately. Perhaps they seem to be growing in popularity because I just started noticing them lately. I do - however - think they are in fact growing in popularity generally speaking.

I asked Grok 3 for some input on the appeal, and advantages of NO MULLION windows in residential apartment buildings.

My Question to Grok 3: Why are the no-mullion windows gaining popularity in residential apartment buildings.
Grok 3 response: No-mullion windows, featuring single, uninterrupted panes of glass, are gaining popularity in new apartment buildings for several reasons:

• Aesthetic Appeal: These windows create a sleek, modern look with clean lines and unobstructed views, aligning with contemporary architectural trends that emphasize minimalism and open spaces.
• Maximized Natural Light: Without mullions dividing the glass, more sunlight can enter, making interiors feel brighter and more spacious, which is highly desirable for residents.
• Improved Views: Uninterrupted panes offer clearer, panoramic views, enhancing the connection to the outdoors, especially in urban settings with scenic skylines.
• Energy Efficiency: Advances in glass technology, like low-E coatings and insulated glazing, allow large single panes to be energy-efficient, reducing heat loss or gain without needing mullions for structural support.
• Structural Advancements: Modern engineering and stronger glass (e.g., tempered or laminated) enable larger panes to withstand wind loads and other stresses, eliminating the need for mullions as structural dividers.
• Reduced Maintenance: Fewer components mean less upkeep, as mullions can collect dirt or require sealing and repairs over time.
• Cost Efficiency in Design: While large panes can be expensive, streamlined designs with fewer window components can reduce labor and material costs in some cases, appealing to developers.

These factors combine to make no-mullion windows a preferred choice for both aesthetic and practical reasons in modern apartment construction.
