Local4 is a company based in Barcelona and Bilbao that carries out landscape projects, at territorial, urban and private level. We understand landscape projects from the point of view of reuse, assuming the local identity, projecting it and reactivating the site’s systems (hydrological, geological, biological, cultural, economic, etc.) From practices based on open processes, we seek to generate tools that are efficient, flexible, decisive and that allow us to be prepared to face an unpredictable future. All of this is supported by a social infrastructure, based on culture, emotion, harmony, the ethics of Nature and a job well done, and with a common objective: to create landscapes of coexistence.

The landscaping project aims to give the site an identity and character, to organise the space, and to bring wellbeing to the users. These objectives are encompassed in a general concept: to create a sustainable landscape of great environmental and visual value.

Criteria for action:
  • Reactivate systems. Hydrological, pedological and ecological systems, etc. Increase the services they offer.
    Improve urban, ecological and community connectivity.
    Open processes from adaptive management in space and time, PHASES to renaturalise. Resilient landscapes.
    Different degrees of intensity and scales of intervention in the proposal.
  • Accept, from the outset, the conditioning factors. The presence of the Blast Furnace, the railway tracks, the wagons. Reuse.
  • Incorporate cultural values.
  • Creating a powerful image. A space that is formalised as a “stain” where most activity is concentrated.
    Involving the population. People’s stories.

The proposed action is based on this concept, intensifying the action in the immediate surroundings and linking the actions in the rest of the park to its singularity. It is proposed to generate a “square” surrounding the Blast Furnace which is formalised in the form of a stain and is intended to recall a smelting spill from the Blast Furnace.

Trees are planted, in the form of a grid, in the heart of this action, tensing the space and giving it a certain order.  The rest of the space is planted with grasses and leguminous plants, with a management model that favours the regeneration of the soil and creates a vegetation cover.

A main route is proposed, with a deactivated concrete surface finish, which connects the two accesses from the urban environment to the park and which linearly converge in the Alto Horno “square”.

Secondary, unpaved routes are also planned, which are opened up to manage the mowing of the proposed meadows. A cycle lane runs along the perimeter of the park.

In terms of signage, “graffiti” signposting is used throughout the park and is intensified on the existing walls. Occasionally, fluorescent thermoplastic paint will be used to increase its aesthetic value and illuminate it in terms of sustainability.

The lighting proposal avoids a museum approach and focuses on a lighting treatment that evokes the Blast Furnace as a working, active infrastructure.

The railway tracks within the area are maintained and there is the possibility of reusing the existing wagons, giving them new uses.


A suburb of Istanbul, until recently an agricultural environment, rapidly urbanised in the 1990s, fragmented, without services, divided by a valley with an area of about 120 ha, today a residual space, crossed by a canalised watercourse, and which has lost a large part of its ecosystemic functions.

Criteria for action:
  • Reactivate systems. Hydrological, soil and ecological systems, etc. Increase the services they offer
    Improve urban, ecological and community connectivity, longitudinally, vertically and transversally. CITY, VALLEY, SEA (dynamise edges, open doors, create bridges, generate flows).
  • Open processes from adaptive management in space and time, PHASES to renaturalise. Resilient landscapes.
    Ecotones. Dynamic edges between the “urban” and the “natural”.
  • Different degrees of intensity and scales of intervention in the proposal.
  • Accept, from the outset, the conditioning factors. By regulation it is not possible to modify or intervene in the canal.
  • Cohabit. Diversity of activities=Diversity of people. Diversity of functions= Diversity of living beings.
    Incorporate cultural values. Water as an identity of Istanbul, water as a religious value of purification. Ottoman abstract geometries, the colourful flowers, the agricultural past as identity, the archetype of the small square + kiosk + fountain +coffee + tree as a meeting place.
  • Create a powerful image.
  • Involve the population.


Objective: To recover the water cycle. All water entering the valley should be clean water.

Purification gardens; Key Lines; Water collection sheets next to the canal; Water mills in the connecting urban squares.

-The combed forest

Objective: To increase biodiversity.  Agricultural activity as an interface in time between the current state and the intended renaturation.

Creation of Key Lines (Technique based on regenerative agriculture); water collection in ponds on the slopes; planting of trees arranged linearly on slopes, Microtopography to direct water and soil cover with grasses and legumes; opening of clearings in flat areas where crop fields are formalised; inflitration areas.

-In transit. do not disturb, soil in work. 

Objective: To restore the soil to good condition, transform it into fertile soil. Minimise the costs of maintenance and management of the valley vegetation.

Action: A management of the valley floor based on holistic management is proposed, a combined management of sowing grasses, legumes, flowering plants, with rotation of cattle, horses, sheep and poultry.

-Linking line.  The valley of life an infinite labyrinth without a centre. Nodus versus centre.   

The aim is to start from a route laid out as a spinal cord and over time reach an extensive network developed from an initial path that is flexible, adaptable and changing over time.
