For over a decade, WebUrbanist has featured a wide range of innovative and inspiring urban art and design projects from around the world. The website has attracted more than 500,000 subscribers and been visited over 100,000,000 times since it was launched in 2007. And while WU will remain online, we are not currently planning to publish new pieces going forward. We greatly appreciate your readership and hope you will continue to explore the site and enjoy the thousands of articles in its archives.

The main page of WebUrbanist features a curated series of resource-rich articles covering some of the site’s most popular and timeless themes — these are intended to be a jumping-off point for diving deeper into topics of interest. Or seek out specific subjects like adaptive reuse, vertical farming, cargo container architecture and space-saving design using the search box.

Kurt Kohlstedt, the founder of WebUrbanist, is currently focused on his work as a writer, editor and digital director at 99% Invisible, a radio show and website about design. With over 500,000,000 downloads to date, 99pi is one of the most popular podcasts in the world. These media projects have a lot in common, so fans of WU are encouraged to check out more articles on 99pi and subscribe to the show.

Kurt was a big fan of 99pi long before joining the show in 2015 and has since become a regular voice on the podcast. He has gone on tour with the show, given talks and participated in panels on subjects ranging from how the invention of Kindergarten fundamentally shaped Modern art and design to the improbable rise of tree-covered skyscrapers.

In 2020, currently co-authored a National Bestselling book with 99pi host Roman Mars: The 99% Invisible City:A Field Guide to the Hidden World of Everyday Design. You can also follow Kurt for semi-regular tweets about design, cities, urbanism and synanthropes.  From the start, WebUrbanist was about making urban architecture, art and design more accessible and engaging to all kinds of people. As you continue to explore the world around you: stay curious, fellow urbanists.

Previously an ongoing publication, WebUrbanist is now a passive archive made up of over 5,000 articles written across 30 categories between 2007 and 2020. The site covered urban architecture, art, design, exploring built environments around the world and reaching a total audience of over 100,000,000 visitors.

Creator and Contributors:

Kurt Kohlstedt founded WebUrbanist before launching a series of other design-centric publications including Dornob, Gajitz and WebEcoist — these days, he is focused on his work at 99% Invisible, a popular podcast and website about design. He also co-authored The 99% Invisible City with 99pi host Roman Mars.

Contributing authors included SA Rogers, Delana Barnes, Steve Levenstein and others over the years. The gifted designer/developer duo of Duck Brigade crafted the current version of this website as well as the snazzy logo.  Mike Waggoner has tenaciously kept the site up and running through good times and bad.

Press and Publicity:

Over the years, WebUrbanist and Kurt Kohlstedt have been featured on a number of other media outlets and popular blogs including The Guardian, The BBC, CNN, NPR, TIME, ArchDaily, Architizer, Atlas Obscura, BoingBoing, BuzzFeed, Citylab, Curbed, Streetsblog, FOX, Gawker, Gizmodo, Martha Stewart Living, Mental Floss, MSNBC, Neatorama, WebWare and Wired Magazine.

Through WU, Kurt became known for his coverage of abandoned places, uncanny graffiti, urban camouflage, transforming furniture, container architecture, modular housing, vertical farming, cycling infrastructure, big-box reuse, street markings, planning history, and civic design commentary. This in turn set the stage for him to write a National and New York Times Best Seller in 2020.

In Newark, New Jersey, a large and deceptively nondescript building is redefining the Garden State, producing millions of pounds of food per year just outside of Manhattan. This 70,000 square foot facility has the equivalent yield of over 5 million square feet of traditional farmland. Inside, a year-round, closed-loop aeroponics system employs no pesticides and requires 95% less water than field farming. This branch of AeroFarms is not alone — it’s part of a food production revolution with projects ranging from at-home and in-store micro-farms to massive facilities set up in old factories and warehouses around the world.

Technically, vertical farming can be done outside, too, by stacking planters in natural sunlight, but indoor vertical farms offer a range of advantages. Inside, there are no seasons and specialized LED lights make it possible to grow plants continuously and cycle through various crops more easily. The controlled environment and standardization of these systems also makes automation easier. In Japan, approaches have gone predictably high-tech, with endeavors like the Vegetable Factory, which is operated entirely by robots.

Spatial containment makes recycling more efficient, mitigates spoilage and reduces the risk of diseases and pests spreading beyond a specific facility. Transportation costs and energy requirements are also reduced for farms that move into old factories and warehouses right in and around cities, putting them closer to consumers. Aeroponics in general also require less material input — mainly mist and air with minimal water and soil — leading to a lighter footprint.

What started in large and independent facilities has begun to spread into mainstream grocery stores and supermarkets, too. A few years back, Target started testing direct retail micro-farms, beginning with leafy greens before moving to tomatoes, peppers and more. Since these kinds of retail spaces are climate-controlled already for the sake of both shoppers and products, less added energy is required to maintain ideal conditions.

In Berlin, a company called INFARM recently partnered with local shops to provide similar in-store services, cutting down on farm-to-table distance right in the heart of a major European metropolis. Meanwhile, in Tokyo, vertical creepers, rice paddies and broccoli fields were integrated into the design of an otherwise Modern-looking office building, brightening up the place while also providing food for the employee cafeteria.

Taking vertical integration a step further, projects like the ReGen Villages aim to incorporate stacked farms directly into residential communities. It may sound impractical or even Utopian, but at its root the idea is relatively traditional: backyard gardens and community gardening are nothing new. Coupled with walkability and density, these kinds of green-centric towns have a lot in common with New Urbanist ideas that go back decades.

Still, it is generally wise to maintain a healthy skepticism when it comes to fresh green architectural trends and technologies and eye-catching renderings. Skyscrapers covered in greenery (or treescrapers), for instance, have proven to be popular but also problematic in practice (catchy conceptual earthscrapers, groundscrapers and sidescrapers, too, for that matter). Sometimes, more practical organic solutions are hiding in plain sight. Take wood, for instance, a historically popular green building material now finding new forms and reaching new heights in tall buildings around the world. Newer is not always better.

Some extreme vertical farming ideas may indeed prove to be far-fetched and unsustainable, but market movements suggest there is a future in these kinds of facilities and approaches. Investors are putting their money where people’s mouths are, buying up disused urban real estate and developing new indoor farming technologies. Already, vertical farming is a $2,000,000,000 industry and experts project it will grow as much as 30% per year over the next decade.

Vertical farms are of course not a complete solution to ongoing threats like climate change and mounting global food crises, but they do show promise — these endeavors are slowly breaking down urban and rural barriers, reconnecting cities with the food sources that sustain them and shortening that critical distance from farm to table.

Blank, windowless exterior walls that get plenty of sun exposure could become vertical farms with the addition of recycled modular scaffolding. A project called GreenBelly aims to make use of these wasted urban spaces to provide fresh food to the surrounding neighborhood with a system that’s easy to transport, install and remove, and it doesn’t even require hookups to utilities. A six-level GreenBelly system made of reclaimed scaffolding and wooden pallets taking up just 35 square meters of land can produce over 14,000 pounds (6400kg) of vegetables per year.

The basic module contains a soil bed, two aeroponic towers and a hydroponic wall, capable of growing hundreds of plants at a time. Multiple modules fit together like Legos, stacking vertically to create multi-tiered open-air structures that harvest rainwater and run on solar energy. The bottom unit contains a farm stand for selling the produce to local residents, and the top level contains beehives to help pollinate the plants and produce honey. Producing and selling food in the same urban location allows the stand to sell fresh produce at fixed, affordable prices.

Created by AVL Studio, a design boutique specializing in sustainable architecture, the GreenBelly system could be run as an educational project by a school, an assistance program for homeless people or an addition to an existing restaurant or market, or its individual modules could be rented out to locals in a manner similar to community gardens. How it’s managed would likely depend on who owns the land it’s built on. The architects estimate the cost of a 20-module unit at about 30,000 euros (roughly $35,000 USD), which could be recouped after three years of operation.

It’s an interesting proposition for the many blind building facades found in an average city, especially in areas where fresh produce is harder to come by. AVL Studio envisions the GreenBelly system being especially valuable in disadvantaged neighborhoods. They’re currently raising money on Kickstarter to build more prototypes at various scales, which could be exported in containers to places that need them most, like Palestine.

Most urban environments aren’t lacking in sunlight – it’s a lack of square footage and healthy soil that makes it hard to use these spaces to grow food. While many a high-tech concept design has envisioned vertical skyscraper farms or entire cities built from scratch, we need low-cost solutions that can be implemented into disused urban spaces, easily assembled and moved when necessary. These smart urban farming and gardening ideas reclaim pallets, cardboard tubes, shipping containers and bicycle wheels, and many take advantage of sunny available spaces on rooftops, in abandoned buildings or along stretches of hot concrete walls.

The Growroom: IKEA Flat-Pack Spherical Garden

Developed by IKEA’s external innovation hub, Space10, the Growroom is a spherical structure that makes it easy to grow lots of food in a compact space thanks to its unique design. Since shipping the structure around the world would be too expensive and negate some of the benefits of local food sourcing, IKEA decided to offer the structure as an open-source design built with plywood, a CNC milling machine and a rubber hammer.

Floating Gardens in an Abandoned Chinese Factory

This area along the Pearl River Delta in Shenzhen was once a thriving community relying on fish ponds and water-based commerce, but most of that has since vanished in the face of rapid urbanization, leaving many abandoned structures behind. ‘Floating Fields’ occupies this space and makes it useful again as an aquaponic garden. Created for the Urbanism\Architecture Bi-City Biennale, the installation is an experiment in water-based gardening, algae cultivation, sustainable food production and water filtering in an underutilized urban environment.

Recycled Cardboard Tube Garden

Water-resistant, recyclable cardboard tubes provide the basis for a modern pop-up garden in Sydney by Australian design studio Foolscap. The tubes were used to build the walls of a temporary outdoor recreation space, taking inspiration from the formwork used to cast concrete columns in a nearby Sydney neighborhood. In addition to an outdoor theater, food and co-working areas, ‘Wulugul Pop Up’ had its own edible garden full of native plants.

Grid Garden on Wheels

This clever portable garden rests on reclaimed bicycle wheels and features an open gridded design so sunlight can reach tiered plants. The ‘Why not in the garden?’ installation by A4A Rivolta Savioni Studio was literally rolled out into a Milan city square to demonstrate how concrete urban spaces can be temporarily used for food production.
