parametric design, architecture and art

Le mois dernier, invités par l’association Assaut Vert et avec la participation de la doctorante Aurélie de Boissieu de DNArchi et le professeur Claire Pétetin, nous avons tenu à l’École de Versailles une conference sur l’Architecture paramétrique et libre de droit, en abordant le sujet de l’architecture paramétrique avec des cas d’application concrète. Retrouvez ci-dessous le support de présentation de la conference en PDF et, bien sur, librement téléchargeable et réutilisable [Licence Creative Commons CC-BY-2.0]



A few months ago we shared with you a free download of our CAD Standards and we were surprised to see that the post became one of the most read of our blog with 2933 pageviews and almost 2000 downloads in total. This was also a good occasion to connect with other people who were working on the same problem.


cad standards

After several months of blood, sweat and tears, we are very happy to share with you a free download of our CAD Standards, the Electronic File Naming Convention and the Project Folder Organisation we will be using at HDA, with immediate effect.

We are a hybrid team of architects, designers and engineers. Even though we strongly believe in this interdisciplinary approach, we understand that it presents difficulties in achieving coherence and clarity in our management systems. The files we are sharing today with our readers are the first outcome of a thorough review and coordination process intended to make our different design tools and activities more coherent.

As noted elsewhere on this blog, at HDA we believe in an open culture, that sharing content can be useful, productive and not anti-economic, and therefore offer these free to download in the hope that they may be useful to others.


formation grasshopper

Comme nous avions déjà annoncé en Mai, et comme il est annoncé sur le site de RhinocerosHDA démarre une nouvelle activité en collaboration avec Rhinoforyou, et organise des formations Grasshopper intégrant un Atelier pratique d’Architecture Parametrique.
Un de ces cours de formation est prévu à Paris du 20 au 22 septembre. Nous souhaitons proposer les 3 formules suivantes en fonction des besoins des stagiaires:

– 3 jours ( Initiation+Atelier ) : du lundi 20 septembre au mercredi 22 septembre
– 2 jours ( Initiation ) : lundi 20 et mardi 21 septembre
– 1 jour ( Atelier ) : mercredi 22 septembre



Just a quick post to share the official press-kit of the recently opened Railway footbridge in La Roche-sur-Yon, with some photos by © Christian Richters/VIEW.

As we have already announced in Italian just befor Christmas, our proposal won the “pylons of the future” international competition for italian energy supplier Terna.
Hugh Dutton explains his intent as it follows:

‘Our own design response is based on changing the current ‘industrial soldier’ image of today’s pylons. Primarily by an elegant shape whose form is inspired by nature instead of galvanized trellises. And secondly by what I called “dancing with nature” where the pylons lean and swerve in response to the topography. They find a structural equilibrium by leaning into the curve of the electric cables as they follow the constraints of the landscape.’

Symbolically this represents a very important project for HDA, as it expresses our deep conviction that new technologies, both in the design phase and in the construction phase, represent a powerful tool to optimally individualize architectures. This thereby avoids the banality of modernism standardization, whilst limiting material wastage, in a similar process to nature’s own selectivity and optimization.

Finalmente possiamo dirvelo. La settimana scorsa, il 16 dicembre, ci trovavamo con HDA a Roma, in occasione della cerimonia di premiazione del concorso Terna per l’ideazione di una nuova tipologia di piloni elettrici destinati alla realizzazione sul territorio italiano.
Come annunciato oggi dal quotidiano La Repubblica, il progetto di Hugh Dutton (HDA) ha vinto il primo premio e vorremo condividere con voi il nostro progetto, proposto nell’ambito del raggruppamento GIORGIO ROSENTAL (capogruppo), HDA Hugh Dutton Associés, Gozzo Impianti e CEGELEC Solutions & Services.

La nostra proposta consiste in un pilone in tensegrity che, grazie all’utilizzo delle tecnologie della lamiera saldata e il taglio a controllo numerico, adatta la propria forma e l’inclinazione ai movimenti del terreno e “danza con il paesaggio”. Questa proposizione, applicata a un “oggetto” fin da sempre percepito come appoggiato sul territorio in maniera astratta e insensibile, rappresenta una sfida radicale che coinvolge non solo l’architettura e la sua implicazione ecologica, ma anche altri campi come l’innovazione tecnologica e culturale.




Complexitys blog was conceived amid much brainstorming and deliberation, and with much enthusiasm, but with little idea of exactly which direction it would proceed in. Little more than two months after its birth and we’ve been surprised and encouraged to see the first important result of our devotion to, and investment in, an open online communication of architecture.
As Domenico Di Siena from Ecosistema Urbano Office explained in our “web for architects” training in Paris, “an architecture office’s blog is not a portfolio or a place to talk about themselves, but rather an incredibly powerful tool to create a community around the office’s activities and interests”.
Two months into the project and several blogs worldwide have begun talking about complexitys, so these words are now becoming reality.


We are happy to post our first entry of our new DOWNLOADS category.
Like a small but growing number of other architecture offices (such as Ecosistema Urbano and Arquitextonica), we believe that sharing content can be useful, productive and not anti-economic.
In other words, we believe in an Open Culture.

That’s why on this post we want to share with you in a free download format, a rhinoscript code (see video above) that we developed for a skylight design in China, which can help with understanding the concept of double and single curvature geometry.
If you are new to rhinoscript, it may help you to have a look at THEVERYMANY, where you will get a better idea of what can be achieved within this format.
