New York’s decades-old pipe-and-plywood sidewalk shed just got its first real-world challenger. Outside the Department of Buildings headquarters in Lower Manhattan, city officials have installed two brand-new shed designs from global engineering firm Arup — marking the first time any New Yorker can walk under one of these redesigned structures on an actual public sidewalk, rather than just see it in a rendering.
From Renderings to the Real Sidewalk
Deputy Mayor for Housing and Planning Leila Bozorg and Department of Buildings Commissioner Ahmed Tigani unveiled the installation in person, giving the public its first close-up look at what the DOB hopes will eventually replace the hunter-green sheds that have lined city blocks since the 1980s. The two models on display — the Flex Shed and the Rigid Shed — will remain up for 30 days so residents, contractors, and design professionals can see and walk through them before wider rollout begins later this year.
It’s a milestone nearly two years in the making. The city brought Arup on board back in February 2024, alongside architecture firm PAU, to reimagine how sidewalk protection could work without the tunnel-like feel New Yorkers have put up with for generations. Arup’s design team — which also includes KNE Studio, Reddymade, and CORE Scaffolding Systems — unveiled renderings of its three concepts to the public in November 2025. This installation is the first time any of those designs have actually gone up outside a design studio.
What’s Different About These Two Sheds
The Flex Shed is built for lighter-duty jobs — maintenance work, emergency repairs, and shorter-term projects. Its roof height and column placement can be adjusted on site to work around real obstacles like street signs and bus shelters, something the current standard shed handles poorly at best. An optional transparent deck lets natural light reach the sidewalk below, addressing one of the most common complaints about existing sheds: the dim, enclosed feeling they create at street level.
The Rigid Shed is the heavy-duty option, designed for larger renovation and new-construction projects. It’s engineered to skip the cross-bracing that clutters current sheds, allowing longer spans between vertical supports. The result is a structure strong enough for major work while still leaving pedestrians with a more open, less boxed-in walking experience.
Both designs are part of a set of six total concepts the city plans to roll out — three from Arup (Flex, Rigid, and the fully building-anchored Air Shed) and three from PAU (Baseline, Wide Baseline, and Speed Shed). Once DOB finalizes the rulemaking process, contractors and design professionals will be able to permit any of the six the same way they currently self-certify the standard green shed — meaning adoption should scale quickly once it starts.
Part of a Bigger Push to Change How NYC Handles Sheds
This installation doesn’t exist in isolation — it’s one piece of the city’s broader “Get Sheds Down” initiative, which has already resulted in more than 15,200 sidewalk sheds being removed citywide since mid-2023. Alongside the new designs, the city has also:
- Shortened shed permits from a full year down to 90 days, requiring proof of active repair progress to renew
- Lowered the threshold for the DOB’s Long-Standing Shed enforcement program from five years to three
- Introduced new penalties, including monthly fines of up to $6,000 for sheds that sit past 180 days without active work, starting in 2026
Commissioner Tigani framed the shift plainly: sidewalk sheds serve a real public safety purpose, but that doesn’t mean the city has to keep accepting the pipe-and-plywood eyesores that have swallowed sidewalk space for decades. With Mayor Zohran Mamdani’s administration continuing to push the initiative forward, this Lower Manhattan installation is meant to be a preview — not a one-off.
What This Means for Property Owners and Contractors
If you’re planning a facade repair, renovation, or new construction project that will require pedestrian protection, it’s worth knowing these new options exist — even before they’re fully available citywide. As DOB works through the rulemaking process, working with a scaffolding contractor who already understands both the current code requirements and where these design changes are headed will keep your project ahead of the curve instead of scrambling to catch up once the new designs become standard.
