From the architect. Located on the periphery of the city, the plot of land offers a spectacular view of Linz, as long as one builds high enough to be able to gaze over the neighbouring properties. That is why the ground storey lies about 6m above street level – with the pleasant side-effect of allowing the garden area to adjoin the living area on the same level to the west and north, despite the extreme slope.
Since regulations only permitted construction up to a maximum of 200m² per storey, it was not so easy to accommodate a spatial plan for a five-person family , especially since all the primary functions were to be arranged in the living area; an upper storey was not desired.
Only the children’s section has a further level; each of the children’s rooms received a gallery with an adjoining children’s balcony, obtained through stacking above the access and sanitary level.
The main entrance (which at the same time serves as a drive leading to the spacious garage area) cuts spectacularly into the embankment, while a single-run stairway leads from the entrance to both the living storey and the cloakroom and wellness area, which is set off somewhat from the entrance. The sauna opens up onto a discreet rock garden on the northern part of the property.
The dark golden brown of the mosaic tiles on both the interior and the facade match the fair-faced concrete surfaces produced from roughly-cut shuttering; the projecting cantilevered roof covers wide-ranging terrace areas, with wooden flooring that continues from the spacious halls in the living areas. The inner and outer living areas are only separated by delicate full glazing, large parts of which can be opened.

The movement and management of sediment is arguably the largest continuous project of spatial manipulation on the planet. This ongoing battle between geology and industry is most apparent through the act of dredging. Dredging is the excavation, gathering, transport, and disposal of sediment from subaquatic areas, enacted to maintain depths of shipping channels, harbors, and ports as well as to reclaim land, create sea defences, and remove toxic chemicals.[1] The primary impetus for dredging is to sustain logistical routes for the shipping industry by countering the forces of erosion, movement, and settling of sediments. Like the logistics of the global shipping industry it serves, dredging is a continual process whose magnitude and significance have fostered their own series of ‘geologics’ – the engineering of material processes that operate in temporal and spatial scales that are geological in scope.[2] Currently in the United States alone, more than four hundred ports and over 25,000 miles of navigation channels are being dredged.[3]
The combination of integrated globalized shipping as well as growing ship sizes has created logistical routes that, as they approach shallower depths close to urbanized areas, require incessant dredging to counter the natural tendencies of erosion and sediment movement. Accordingly, dredging is continually reconciling the meeting of anthropogenic forces on land with shipping logistics on water. This ceaseless process of dredging – the co-making of hydrological and geologic processes – has been termed the ‘dredge cycle’. It is cyclical because it is constantly driven by anthropogenic influences that produce erosion (urbanization, agriculture, deforestation, damming, etc.) and the desire to tame the effects of these forces that cause shoreline fluctuations.[4] Ironically, dredging accelerates the forces of erosion that they are established to counter, thus stimulating more-and-more dredging.[5]
Given the complexity of engineering a logistical cycle to counter geology, dredging is currently a highly top-down process. It should be no surprise that the largest dredging organization in the United States is a branch of the army, given that logistics itself was born from military operations. To execute this massive land manipulation project, The US Army Corps of Engineers uses an extensive number of (relatively) small instruments such as barges, geotubes, mechanical dredges, hydraulic dredges, cutter dredges, dragheads, suction pipes, trucks, tractors, backhoes, geotextiles, pumps, and silt fences, amongst others.[6] These almost ubiquitous instruments are the primary components of a logistical sequence that includes the removal, transport, and disposal of sediment. What varies in the dredge process is the selection of technologies – decided through a combination of natural geology, available technology, volume, and costs – as well as both where and how to dispose of its material. Traditionally, dredge material was highly contaminated and placed in confined disposal facilities (CDFs), which are now approaching maximum capacity and becoming a costly venture.[7] Another method of disposal has been open water dumping, but the environmental ramifications of this approach are still not fully understood. As a consequence, new ‘beneficial uses’ are actively being sought for dredged material that positions this sediment as a resource.[8] Beneficial uses are part of a longer-term strategy of sediment management that focuses on environmental health, such as: topsoil creation, aquacultural facilities, beach nourishment, aggregate for construction material, brownfield improvements, and habitat restoration. Yet in the context of the United States, despite this transition from a linear process of dredging and dumping to a productive and opportunistic cycle of sediment management, little design effort has been granted to how the engineered geologics of dredging itself – a continual backdrop to urban life in most cities – can be rethought more holistically to benefit currently unheard yet affected subjects.
The dredge cycle can be used to unpack the relationship between anthropogenic and geologic influences that are negotiated through dredging. To short-circuit this relationship would entail the introduction of currently silent subjects that are implicitly implicated in the dredge cycle and question how these subjects can leverage the actual geologics of dredging. For instance, how can local populations re-appropriate this process for socio-political engagement and empowerment? How can ecological processes be an integral component to this system to reduce the environmental footprint of dredging? How can dredging be used as a mechanism to remediate territorial ecologies that it has traditionally impacted? The potential here is to re-envision how smaller components – both physical (instruments of dredging) and systemic (within the geologics of dredge) – can be tactically expanded to both engage and integrate local populations and environments, while strategically aggregated to address urgent issues at a territorial scale. Using differential and overlapping timescales, we ask how incrementalism, dispersion, and iteration enable new subjects – human and environmental – to co-evolve with the dredge cycle.
Dredgescaping Toledo is a design case study that attempts to advance a new discussion on the geologics of dredge by focusing on the Maumee Bay on the western edge of Lake Erie and part of the Great Lakes navigation system. Dredging in the Great Lakes began over one hundred and fifty years ago, and currently over three million cubic yards of sediment are dredged annually from its 136 harbors and 745 miles of federal navigation channels. The removal of this sediment from the Great Lakes shipping channels costs the U.S. Army Corps of Engineers between twenty and thirty million dollars annually.[9] Shipping, however, generates over thirty billion dollars in annual revenues for the region.[10] Almost one-third of dredged material from the entire Great Lakes system – approximately 800,000 cubic yards – originates in the Maumee Bay adjacent to the City of Toledo. Dredgescaping Toledo proposes a series of tactics that we have termed tributaries, islands, sponges, and lakes to expand the geologics of dredge.
As Toledo grew beyond its urban core, its fabric encircled the industrial lands that first colonized the riverfront. These lands are still extremely productive – the port of Toledo is ranked seventh in the Great Lakes in total tonnage, generating nearly seventy million dollars in personal income and supporting fifty thousand regional jobs.[11] While these industrial lands are vital to the city’s economic health, they have forged a wall between the expanded city and water. A continuous linear public waterfront is perceived as a cultural catalyst for gentrification in struggling cities such as Toledo, though here rendered implausible. Instead of negating industry, this study employs a series of connectors between land and water – tributaries – that provide a public easement and access through the port’s terrain vague while seldomly interfering with the industrial lands and processes themselves.
Presently, Toledo’s dredged material is disposed of in an existing two square mile open-lake placement area, located at the mouth of the Maumee River. Not only has this disposal technique been associated with inciting algae blooms in Lake Erie that suppress aquatic ecosystems,[12] but by dumping this material far from the City of Toledo it is difficult to leverage as a public amenity. Due to the Maumee River’s narrow width, steady flow, and considerable shipping routes, it is impractical to dispose of this dredge sediment in the river itself. We see this material as being capable of creating vital and lacking public waterfront lands for the city. Working within the geologics of dredging, we ask how land can be operationalized in its different states of matter – from slurry to soils – and cleanliness – from partially contaminated to remediated – to enable the co-existence and symbiosis of industry and public life. Our proposal utilizes a series of geotube pontoon islands to process the dredged slurry in close proximity to the city.
Geotubes are massive ‘sand bags’ fabricated from flexible geotextiles that hold and dewater newly extracted dredge slurry. Dredge material is pumped directly into these bags, and over the course of three months purified water slowly seeps out. What is critical about this technology is that the tubes can be fabricated in a variety of sizes and are easily filled, deployed, emptied, stored, and transported. This enables dredge slurry (both water and sediment) to be dewatered and remediated in close proximity to the city of Toledo without disrupting draft depths or navigation routes. Geotubes can be inhabited during the dewatering phase as islands and treated as public land. During the dewatering phase, these islands host a series of programed platforms that connect to the easement tributaries, forming a poly-nuclear public waterfront – an evolving archipelago. These pontoons are grouped into larger figures to provide different programmatic opportunities for a city starved of public space and access to water. This disaggregated approach to managing dredge sediment establishes a highly flexible and resilient system, as temporal public land is incrementally deployed alongside and within the dredge cycle and can therefore be calibrated to seasonal changes, festival and event schedules, or the general needs and desires of local citizens. This inserts a bottom-up, tactical, and iterative approach to forming public space within the geologics of dredge.
After the dewatering period, the public island platforms are removed and reinserted into newly dredged pontoons, while the dewatered pontoons are ‘unzipped’ and hydro-seeded for a phase of phytoremediation. These floating wetlands are connected to the stormwater culverts and detention basins that are integrated within the easement tributaries. Once the sediment is remediated and safe for open-lake placement, the soil in the pontoons is mixed with a rare-earth bentonite and water solution, which acts as a sponge to suppress and absorb algae growth. This allows territorial issues like harmful algae blooms or other specific ecologies to the lake to be addressed in an appropriate timescale. The sealed geotubes are then tugged into the bay and the slurry is distributed throughout Lake Erie. Over several years, this process is anticipated to return Lake Erie to its original nutrient composition. The emptied geotube pontoons can be either reinserted into the dredge process or stored, depending on the season.
The last component of this design study examines how the dredge cycle can more robustly interface with the hydrological cycles of water management in the city. Due to a large number of combined sewer overflow events, the Environmental Protection Agency has mandated new forms of stormwater management for Toledo. While the city contemplates a series of hard infrastructures and the consolidation of stormwater onto three sites, our proposal investigates how a distributed approach to water management can reduce contaminants caused by the large distances traveled by stormwater run-off, and once again, disaggregate a sizable (and potentially expensive) problem into a series of distributed soft components. The study proposes the employment of foreclosed home sites in Toledo as a series of distributed detention basins. These ‘waiting lands’ are operationalized by creating a perimeter curb of dredge-filled bags around the house and property line to allow stormwater to fill these sites and reduce pressure on the sewer system. In total, this ‘distributed lake’ consists of an area of land equivalent to the three sites currently set aside by the city. Further, public platforms from the islands could be placed on these lots – resting on the curb foundations – to enable local neighborhood public programs when not in use on the river.
The proposed geologics of dredge enable local environments and citizens as well as territorial transformations to co-evolve with and through the dredge cycle. The expansion of ‘beneficial uses’ that moves beyond sediment repurposing requires engaging with the system of dredging itself and asking how it can be a resource to cities and their ecologies. This strategy has the potential to implicate new subjects into what was once a top-down linear system. While the health and growth of industry instigates dredging operations, these operations also accelerate erosion and therefore more dredging. This means that where industry is steady or flourishing, dredging operations are continually increasing in scope. Dredged sediment acts as a material index to the prosperity of industry, yet in mid-sized towns with industrial waterfronts, how this new land is processed and disposed of can be advantageously reconsidered. While dredge material is often used to create new lands, particularly in cities boasting high real estate values, as the histories of Toronto, Boston, New York, and San Francisco, amongst others has shown, these cities have used these same real estate values to push industry to the periphery and return their waterfronts to the public. In the context of mid-sized cities such as Toledo, where low land values, productive industry along the water, and an associated depravity of public space collide, a system of producing land in a malleable, temporal, transformable, and transportable logic enables the symbiotic co-habitation of industry, culture, and ecology. This positions land not as a commodity to capture and hold, but rather a temporal material state that is iteratively deployed and used by local constituents and then redistributed within a territorial ecology. Within this expanded geologics, culture, politics, economics, and ecology find synergetic opportunities that empower new subjects to be agents within what was once an engineered system of global capital.

From the architect. The program, conducted in the psychiatric sector of a hospital, required the restructuring of the headquarters and the rehabilitation of the Institute, together with the building of a new extension of 2300 m2. Atelier 2 + 1 was involved in all of the developing the program and in participating in the definition of the requirements with the relevant services and the patients.
The existing building consisted of two perpendicular structures of which the facades were maintained to comply with the provision of ABF (Les architectes des bâtiments de France): a Haussmann building overlooking the street, with a vaulted porch, and a right wing with a modern structure dating from the 1960’s. A dreary courtyard was used as parking. The extension which encloses this courtyard now provides continuity and consistency between all the different levels of Haussmann and modern buildings.
The three buildings, including the new restaurant on the ground foor, open today on a new mineral square, which generates light. Above all, this patio symbolizes the desire of the agency to provide soothing living spaces in this health care environment.
As further evidence, the multipurpose room to be found on the first floor and the two spa rooms installed in the basement. This design also made it possible to simplify and optimize the labyrinth that was used as a place of passage.
The mirror effect of the glass extension reflects the distinct character of the two other buildings and brings in the nearby city. The access from the street to the paved courtyard and vice-versa makes it easy for the patients, the majority of whom are ambulatory, to have access to the place with a friendly atmosphere.
In this specific environment, the work was carried out in occupied site with special attention to the welfare of the patients and that of the Institute ‘staff.

From the architect. The house was designed for a sixty year old couple. Prior to construction the building site was characterized by flat and natural forestry.
At the first meeting after receiving the program, I presented two basic alternatives to the customer the plan that was selected was for the trees on site to dictate the planning of the home.
The initial planning incorporated placing a rigid square criss crossed with porous holes , the effect of the division within the square is similar to the closed and open spaces of the home i.e the covered and non-covered area depending on the location of the trees.
This is like laying an outstretched extended hand between the trunks out of a desire to preserve them as much as possible.
Upon diving into the detailed planning, the rigid frame of the square was broken, and the house was divided into three parts: a central one which connects to two secondary parts through two “connectors” – which are narrow transparent passages. Among the three wings – Courtyard retains the natural state of the area prior to the construction and the fourth area there is a bridge, which in effect defines an internal space beneath the open sky, while below is the garden.
Most of the house is characterized by openings that reach from the floor to the ceiling on all sides of the house, except for the West, which is shaded this blurs the transition between interior and exterior, creating a constant shading on the primary openings.
Central Division: Space height of about 4 m includes, dining area, kitchen and storage room. This space functions additionally for a t dining table, seating area and outdoor kitchen.
The south rear wing includes: bedroom, bathroom and walk-in closet.
The north wing towards the street includes: guest room, bathroom, kitchenette and a den / office. Glass walls on its exterior characterize this division. The study, which is located at the eastern end, is open on three sides to a natural forest.
The ceiling height in the secondary spaces is 3 m.
The vegetation has been added to the existing vegetation is characterized mainly local vegetation such as olives, oaks, figs, etc.
