From the architect. For the Greek, Hemeroscopium is the place where the sun sets. An allusion to a place that exists only in our mind, in our senses, that is ever-changing and mutable, but is nonetheless real. It is delimited by the references of the horizon, by the physical limits, defined by light, and it happens in time. Hemeroscopium house traps, a domestic space, and a distant horizon. And it does so playing a game with structures placed in an apparently unstable balance, that enclose the living spaces allowing the vision to escape. With heavy structures and big actions, disposed in a way to provoke gravity to move the space. And this way it defines the place.

The order in which these structures are piled up generates a helix that sets out from a stable support, the mother beam, and develops upwards in a sequence of elements that become lighter as the structure grows, closing on a point that culminates the system of equilibrium. Seven elements in total. The design of their joints respond to their constructive nature, to their forces; and their stresses express the structural condition they have. By the way this structure is set, the house becomes aerial, light, transparent, and the space kept inside flows with life. The apparent simplicity of the structure's joints requires in fact the development of complex calculations, due to the reinforcement, and the prestress and post-tension of the steel rods that sew the web of the beams.

It took us a year to engineer but only seven days to build the structure, thanks to a total prefabrication of the different elements and a perfectly coordinated rhythm of assembly. All of our effort oriented to develop the technique that would allow to create a very specific space. And thus, a new astonishing language is invented, where form disappears giving way to the naked space. Hemeroscopium house materializes the peak of its equilibrium with what in Ensamble Studio we ironically call the "G point", a twenty ton granite stone, expression of the force of gravity and a physical counterweight to the whole structure.

Doug C. · September 22, 2011

Well, you can't accuse it of being under-engineered. Is the point to use enough resources to build fifty homes? You could probably build one hundred Jean Prouve houses with the same weight of materials.

Randy · September 22, 2011 07:24 PM

My point exactly, one little void in the concrete support and you`re looking at a 4-foot tall house.

Nice project, but I don t understand why they put that sh*t at the end. It wastes everything!!

Is Hemeroscopium a real world or has it been invented for this house? If so, what words are there that could be used for a position to view the setting sun?

Randy · September 22, 2011 08:08 AM

Um...facing west? (Sorry!) XD

Randy · September 22, 2011

"Hmmm, let`s see...hey, tell you what, let`s add 20 tons on top of it!" "Yeah, I`m sure THAT won`t cause any problems in years to come!"

joseph n. biondo · September 22, 2011

Very interesting hybrid structure. Robust, bold, muscular -have not seen that level of rigor with precast since Gordon Bunshaft. Great work!

KALIKA · September 22, 2011

Nah, this guy has better works.This is just a tribute to Fernando Higueras of whom Mr.Garcia Abril is very fond of, nice try but not even nearby.Ask 'em about SGAE.

Antón García-Abril hires his "employees" this way: you have to work FOR FREE in his studio for 6 MONTHS, and afterwards he will decide if you continue or not (and of course, in which conditions). And he talks about ethics...

Ótimo projeto que associa a construção [de forma invoadora] com a integração dos espaços. Vale a pena ver o vídeo.

A cantilever lap pool? Hemeroscopium House / Ensamble Studio.

WOW!! That's a brilliant idea!!

After that stone, the structure is balanced. You could take out the extreme pillar, and it won't fall down.

Bo Lucky · May 04, 2009

Genius???? It's just a different kind of Lego structure... any 5 year old could do it... or even be better!!! Is a question of having big enough cranes...

Guido · May 04, 2009

Genious! with a passion for civil engineering, this is like playing piano with Mozart, thank you guys!!

??????????. ???????????. ??????? ?????, ?????? ??????????????? ??????, ?? ???? ???????????

Is more tremendous. Perfectly well. The decision crude, ?????? not worked absolutely, but language is magnificent

chuck · April 19, 2009

i'm intrigued by its very nature but dissappointed in its excesses ... ain't it time to produce impressive works reflecting the real ecological issues of working in concrete ... brute force is hollywood ... architecture needs to resonate in a more meaningful way ... still like it.

Robert · April 05, 2009

Congratulations. Brilliant.

chicago.g · March 14, 2009

one of the best throughout!!!

NIM · March 13, 2009

Very interesting idea!
I have dreamed about living with express way structure.

It would be the best if those massive concrete beams are something left from the express way or bridge construction projects.
Or the beams are the standard shapes from factory that regularly prepare such concrete beams for infrastructural projects.

Anybody know about this in detail?

Ariel · March 13, 2009

Wow, great details, great idea.
As a student I have really enjoyed looking through the draftings.
Thank you

mil · March 13, 2009

Pure architecture............Is not in the shape............ is something more than a pretty construction.
there is a mistery in between matter and void.

ornament and crime · March 13, 2009

This is architecture of bold structural purity.

It is beautiful.

Bernie Madoff · March 13, 2009

Hey Martin, you write as if there were any truth to be found in aesthetic proposals. That up there is architecture. It's the product of contingency, subjectivity and culture. And I don't need to like it in order to acknowledge that is pretty awesome project.

Martin · March 13, 2009

"..we ironically call the “G point”, a twenty ton granite stone, expression of the force of gravity and a physical counterweight..."
They just invented a new problem, not a new solution. If not, why on earth would you need a stone like that in the top of the house?
They talk about new languages, but for me, they just took the metaphor and irony too far.
Even Ventury would say that they took the idea too literally.

radirfej · March 13, 2009

it has to be joke. a bad one.
maybe it's an interesting idea to sail till the border, but in this case it resulted in a merely gag, I think.

Nomads Architects · March 12, 2009

Thermal bridges are not always a question of losing calories. You can have a local condensation of the vapor. Insulation is working for both ways : hot countries and cold countries.

ranuhasu · March 12, 2009

Very interesting - achieving a well-balanced art composition that`s also habitable... very nice - still, how about the thermal bridges?... resolved by the warm Madrid climate?

00-Arch · March 12, 2009

Wow!...Too bad you can´t do that in seismic regions. Or am I wrong?

Randy · September 22, 2011 07:20 PM

God knows, you better not!

Zifeng · March 12, 2009

what is that cantilevered part? is it a swimming pool?

odris · March 12, 2009

Very creative, love it!

Sander · March 12, 2009

this is soooo nice... I love it!

Nomads Architects · March 12, 2009

Nice project ! Interesting technical details, but a lot of thermal bridges...

_m · March 12, 2009

I love easiness of video presentation! :)

Architecture is marvellous,
sensational internal-external spaces connection.

final photos are stunning!

low · March 12, 2009

and sò?? what the reason for?

Vladimir Konovalov · March 12, 2009

it's like a huge LEGO. interesting principal, but I don't like the result at all, strangeful place for living...

sgurin · March 12, 2009

?????????, ???????? ????. ??? ???????????.
Fun, fun idea. I like.
