Weddle Gilmore Rammed Earth

Weddle Gilmore Black Rock Studio has developed a specialty in trailheads over its 10 years in business. The architecture firm has designed this building type for several municipalities near its Scottsdale, Arizona, base, and it has realized three for Scottsdale’s McDowell Sonoran Preserve alone.


The Gateway to the McDowell Sonoran Preserve, Scottsdale, Arizona

The Gateway was designed to celebrate the entry and passage into the 36,400 acre McDowell Sonoran Preserve while minimizing the impact on the native desert. The Gateway is the point of access to over 45 miles of trails within the McDowell Sonoran Preserve for hiking, bicycling, and equestrian enjoyment. The project site design achieved the complete preservation of the existing network of arroyos and minimized earthwork alterations of the natural habitat. The building walls are made of rammed earth, recalling a tradition of indigenous desert building while meeting all of the performance requirements of modern use. The roof is covered in native desert cobble so that it blends into the desert when observed from the mountain trails to the east. The Gateway incorporates numerous strategies for resource conservation. An 18 KW solar system generates as much solar electricity as the Gateway consumes to realize a ‘net zero’ of energy consumption. Up to 60,000 gallons of rainwater is harvested through roof collection and storage in an underground cistern–providing 100% of the water needed for landscape irrigation.


Lost Dog Wash Trailhead, Scottsdale, Arizona

On the perimeter of the McDowell Sonoran Preserve, the Lost Dog Wash Trailhead is an example of commitment to environment through its preservation of native habitat, choice of sustainable building materials, and natural resource conservation. The structures are nested into the landscape and incorporate materials that blend with the natural desert environment. The rammed earth walls of the structures utilize earth material that was excavated during foundation construction. The trailhead restrooms incorporate a composting system which minimizes water consumption and saves approximately 200,000 gallons of water annually over a conventional system.

Gray water and rainwater harvesting provides 75,000 gallons of water a year for landscape irrigation. Solar power is provided to the trailhead facilities by a roof integrated 3,000 watt solar electric array that allows the trailhead to be completely self-sufficient and independent of the electric grid.

Radiolara Pavilion

In a small shed on an industrial park near Pisa is a machine that can print buildings. The machine itself looks like a prototype for the automotive industry. Four columns independently support a frame with a single armature on it. Driven by CAD software installed on a dust-covered computer terminal, the armature moves just millimetres above a pile of sand, expressing a magnesium-based solution from hundreds of nozzles on its lower side. It makes four passes. The layer dries and Enrico Dini recalibrates the armature frame. The system deposits the sand and then inorganic binding ink. The exercise is repeated. The millennia-long process of laying down sedimentary rock is accelerated into a day. A building emerges.

The new material (inorganic binder + sand or mineral dust) has been subjected to traction, compression and bending tests. The results have been extraordinary and the artificial sandstone features excellent resistance properties. Effectively this process returns any type of sand or mineral dust back to its original compact stone state.

The binder transforms any kind of sand or marble dust into a stone-like material (i.e. a mineral with microcrystalline characteristics) with a resistance and traction superior to portland cement, to a point where there is no need to use iron to reinforce the structure. This artificial stone is chemically one hundred percent environmentally friendly.

The process is four times faster than conventional building, costs a third to a half as much as using Portland cement, creates little waste and is better for the environment. But its chief selling point may simply be that it makes creating Gaudiesque, curvy structures simple.

Musgum Architecture

The Musgum, an ethnic group in far north province in Cameroon, create their tall conical dwellings from compressed sun-dried mud. Called Cases Obos, the profile of the structure is that of a catenary arch— the ideal mathematical form to bear a maximum weight ?with minimal material.

The relief pattern on the surface is a built-in scaffolding that can support the body to allow for maintenance of the structure by the re-application of mud to the surface.

The Mud Tub

The Mud Tub, by Tom Gerhardt, is an experimental organic interface that allows people to control a computer while playing in the mud. By sloshing, squishing, pulling, punching, etc, in a tub of mud (yes, wet dirt), users control games, simulators, and expressive tools; interacting with a computer in a new, completely organic, way. Born out of a motivation to close the gap between our bodies and the digital world, the Mud Tub frees the traditional computer interaction model of it’s rigidity, allowing humans to use their highly developed sense of touch, and creative thinking skills in a more natural way.

Could building architecture with mud coincide control 3D printers producing earth buildings while being powered by the mud itself?

Here, Matt Parker’s Lumarca and Tom Gerhardt’s Mud Tub join forces to make some cool interactions happen.

Watertower Skyscraper

The conflict over water and land in Sudan has created political unrest for decades. However, in 2007, scientists from Boston University discovered and underground lake in the region of Darfur, Sudan. This lake is tenth biggest lake in the world (31, 000 m2) and would have great potential in resolving the conflict if managed correctly. Addressing this water issue, Polish architect Hugon Kowalski from H3AR Architect and Design recently proposed a building that allows access to underground waters through the application of water pumps. The form of the building was inspired by a water tower and also by the symbol of the African savanna—the baobab. The building houses water pumps, a treatment plant but also a hospital, a school and a food storage center. This building is meant to provoke economical development but also stimulate cultural exchange and the coexistence of the three different religions and languages in Sudan.

The building walls are constructed using compressed dry stacked clay bricks, made on site using a rough mixture of earth, cement and water. The bricks would be baked in the hot sun, thus, requiring no extra energy and limiting the environmental impact of the materials. The choice of using this technology represents the desire to introduce alternative and sustainable technologies within a context that is tied to standardized though not always optimal building practice.

Two water circulation processes would be in place. First set of extracted water is meant to heat or cool the building, and is accessible to the users. Second, set of extracted water is used for the building itself (i.e. kitchen, toilets).
