ANTONIO CONEJO architect, structure engineer, certified passive house designer

“If I had asked the consumers what they wanted, they would have said: a faster horse. A customer needed a horse, we offered a car, he didn’t hesitate”. (Henri Ford).


ACYA-architecture & engineering team is run by Antonio Conejo who is an Architect, Structural Civil Engineer, and Certified passive house designer. Acya offers the planning and advising the whole project architecture, structure, instalations and construction. 


In every project, we begin a new way using all factors that take part in it (program, aims, plot, rules, environment, structure, building services,...). The proposal we show the client is the last step of a really long process that take us to an unknown initial proposal which may be very different from usual models.


The preestablished models are studied at the beginning as an example of functional distribution that becomes an additional factor more.


We don't do sculptures, we do architecture. We understand "architecture as a beautiful art, whose main purpose is it usefulness". 


All project stages, from concept desing to final documents (architecture datails, foundations, structures, electrical installations, plumbing, water supply, budget...) including the construction control, are carried out by ACYA's staff.


It allows us to deep total control on the project, that guarantees the construction of initial concept.


The Antonio’s professional training as Architect and Structural Civil Engineer. allows him to avoid the separation between subjective and objective processes, architects and engineers. This situation is very usual in real culture with not good results for owner or project sometimes.


Nowadays, the usual confrontation between architects (a humanist, a designer of ideas) and engineers (technical) is due to the need to adapt the architect’s job to the engineering. The consequence is sometimes the preliminary design distortion. Only the considerations of humanist and technical factor when the idea is being created, would avoid the previous clash.


Those ideas are born from the subconscious. They’re consequence of its creator’s knowledge, the architect.


For us, the solution is the architect and engineering’s skill, the mixture between creation and Knowledge. It should permit him to be placed between humanism & technique. In this situation the artistic perception and the technical influence each other. The first one is influenced by the second one, and the one goes ahead to make the first possible.


To get the enrichment between architecture-engineering, humanism-technical, without any imposition of one on the other, requires that both abilities must be in initially in the same person. It has to be the person who creates the idea, it normally is the architect.


This is the reason that allows to Antonio Conejo to conceive projects that are real from their birth. They are developed by ACYA with his continuous supervision. It guarantees the keeping of the preliminary design.
