what ? is HELLAΣTOCK HELLAΣTOCK is part of Bellastock’s network of students and young architects, which encourages cooperation in activities and projects related to architecture, city and space. It is a platform of research and action, which aims to promote experimentation in architecture as a driver for innovation and as a learning process.

Bellastock started in 2006, from students of Belleville School of Architecture in Paris. Since then, it gave rise to many similar workshops all around the world in cities such as Mexico City, Madrid, Aarhus, Istanbul, Stuttgart, Chile.

The common element among these events is the idea of experimentation with a single material or a combination of materials, resulting in the construction of an ephemeral city. This type of city lasts only as long as the workshop’s duration is and the participants experiment in fabricating their shelters for that time. The theme and the selected materials of the workshop are determined by a scenario, which creates narratives for a future city and proposes different, even utopian, urban structures.

HΣ ’14 hanging! city Re-building from disaster is a proven need of the architecture practice as the world stands against unexpected events such as natural catastrophes.

Experimentation over social habitation in extreme conditions is one of key features of HELLAΣTOCK 2014. In order for participants to answer this question, the following scenario underlies the whole venture, a scenario determined by two key factors:

the emergency of provisional

accommodation of a large number of people within the urban environment as well as the need, for any reason, to lift this peculiar habitation from the ground.

The need for immediate - yet temporary - sheltering of large groups in a limited urban space leads inevitably to architectural forms, which are developed vertically, following the evolution of cities over time.

This context could derive from various possible scenarios such as climate change and hazardous weather phenomena, as well as social situations.

However, it is not the purpose of this workshop to give a clear answer to a specific scenario, but to experiment over creation of minimum space for habitation through architectural forms, always within the given hypothetical context.

destination experimentation for

Athens is the southest capital city of continental Europe and capital of Greece. It is one of the emerging metropolitan areas in Europe with potential, a densely populated area with remarkable urbanity. The history of 3,400 years is imprinted in urban landscape, as history’s palimpsests can be traced within contemporary public spaces, museams even dwellings.

Today Athens is trying to balance in between its deep historic path and ephemeral character of a crisis - scape. In this fragile balance we choose to experiment over the issue of the ephemeral city through HELLAΣTOCK 2014.

& construction

HELLAΣTOCK 2014 is not just another construction workshop. In order for participants to start thinking with their hands, we propose a widened program of both theoretical and practical research.

Thus, participants will be experiencing two complementary frameworks context and construction - taking place in Athens (5 days) and Piraeus (3 days) in sequence . These two locations have been inextricably linked from antiquity, as Piraeus was the port of the ancient city of Athens. Today, Piraeus is located within the wider urban area of Athens and is one of the most promising spots of the contemporary metropolis. On the 28th of August 2014, 150 young architects from all over Europe will meet in Athens where they will implement the design of their provisional houses, forming an ephemeral, hanging city.

Silo, Future Cultural Coast, Port of Piraeus CONSTRUCTION | EVENTS & PARTIES Piraeus is the main passenger and commercial port of Greece and one of Europe’s southest ones with a great geographic location and a history that goes back to Ancient Greece (6th century BC). Later on, Piraeus area became one of the most significant industrial areas of Athens, as a result of the neighboring to the port, as an important trade centre.

Nowadays Piraeus Port is one of the most important ports in the Mediterranean, and a major economical factor for the greek economy, which as a gateway to the islands in the Aegean Sea, it finds itself well interconnected to the rest of the city.

It is a place where the traveling spirit goes part and parcel with the nostalgic feeling of return, one of the most lively parts of Athens metropolitan area.

The construction part of HELLAΣTOCK 2014, will be held in the premises of Piraeus Port Authority and more specifically to the future Cultural Coast, around the Silo and conveyor belt building on the one side and the drydocks and the museum-vessel 'Liberty Hellas' on the other.

Piraeus, as a harbour, it is a place that never ceases to function as a social space, a meeting point, bringing together people from all around the world, an ideal place for creation.

Among the premises of the port one can recognize the various aspects of Ietonia Gates, the western boundaries of ancient Athens, until its industrial

cultural heritage within the premises of a well functioning port, Piraeus Port Piraeus Cultural Coast. Part of this plan is also the transformation of the Silo

material matters Following the principles of Bellastock we will be experimenting with specific materials with a view to design and construct the habitation cells. For HELLAΣTOCK 2014, hanging city, the selection of the materials is determined by the site-specific circumstances, the warm climate in Athens during the summer, the “unbearable” sun at midday. What is the least you need to protect yourself from these natural conditions? What is the “minimum existence”, allowing you to live comfortably in the mediterranean climate?

As one can easily realize, observing impromptu constructions in the street markets as well as well-designed open-air space, this element is nothing but a simple fabric, tensed above the ground, shading its surroundings.

Given the need to move this habitation away from the ground, as a way to face unexpected natural phenomena, what would be the combination of materials which best responds to all the issues mentioned above?

22

This being the primary thought which makes us begin our journey, we propose the use of three complementary materials, the further elaboration of which should produce inventive architectural forms able to stand in this specific environment. Those will be scaffold elements, that will serve as shelters.

STEP 1 You apply for participation as a member of a team by sending all the needed information, as described below.

STEP 2 We review all the projects received and for those approved, we ask for more details. All of you will receive a response as soon as all the projects

STEP 3

have been meticulously examined.

After having received all the necessary information, we proceed to an overall composition of the habitation cells.

This step is very important, given the fact that the scaffold part of your units must be set up before your arrival due to time and safety restrictions!

STEP 4 You arrive in Athens as participants of HELLAΣTOCK 2014, Hanging City. NTUA School of Architecture will host the following

STEP 5

five days for lectures, studios, nights out etc.

We are moving on to the construction site, on the premises of Piraeus port.

STEP 6 The construction site, as it has been formed, opens to the public as an exhibition for a short period of time.

STEP 7 The final report is on the way!!

how to apply

L Y

Download the materials & design a proposal for your hanging / suspended shelter using scaffold, fabric and rope in groups of 3-5 members. *Take into consideration the details on the following pages.

Fill in the Online Application Form until the 15th of June 2014 (!) on participants.hellastock.org for your group and upload your proposal (PDF & SketchUp-File), following the on-screen instructions.

Wait for our answer to approve your participation with more info on the design procedure and the upcoming days in Athens.

We‘ll need some more construction details of your proposal later on... we‘ll stay in touch!

To participate in HELLAΣTOCK ‘14 you have to form a team of 3 to 5 members which at first will design and then will construct a suspended shelter.

You are requested to design a unit that consists of a scaffold frame with the "living spaces" created out of rope and fabric. Your unit's scaffold frame has to be statically autonomous, meaning it should not depend on any kind of foundation or base or neighbouring structures.

It is mandatory that each unit be connected to the common circulation structure (corridor and staircase) and most likely have neighbouring units.

While designing your unit, you must keep in mind the following: 25
