Casa Mara, Modular project (1974)


Casa Mara is a housing proposal based on a model house manufactured by architect Jorge Castillo Plaza, in 1974.

It is a circular fiberglass house, whose shape is inspired by structures in nature, and integrates Indian housing archetypes, like the hut.

Due to its institutional use, these replicas were known as “IPOSTEL modules” and in some cases also as "mandarins" because, in addition to its shape reminiscent of the fruit were painted orange. Today, they are reminiscent of the exercise of creating utopias. Hence the importance of localization and cherishing these ideas in the context of the recent history of architecture created in our country. A project included in the exhibition “Latin America in Construction Architecture 1955 – 1980”, carried out by MoMA in March 2015.

Maison Mara is located: Los Ruices Shopping Center, El Marques Shopping Center and Páez El Paraiso Avenue in Caracas. Potrerito escalade à San Antonio de Los Altos. There is a group belonging to CIEPE houses, San Felipe, Edo Foundation. Yaracuy. a house was installed in the archipelago of monks to establish the sovereignty of the territory. In Tasting, on the coast of Aragua no other. Work is spread across the country, we have to search and find. I invite you to get the Mara house and the photography for the Venezuelan mobile architecture photo competition organized by @Banesco Banco Universal. They can also photograph any other leading Venezuelan architectural work. To participate just upload the photos to your Instagram account, labeled # Venezuelan architecture 2015 and write the location of the shot with a comment on the condition and use.

CONCLUSION: The current strong demand for housing and multiple spaces, in particular social interest, high construction costs, the questionable quality of works for low-income people are the reasons why it is necessary to generate short-term solutions. The use of prefabricated structures as part of the building construction system proves to be the way to go through the constructive and organizational advantages it offers., which are reflected in its duration and the final cost.

However, if, this research found that prefabrication is only a tool that should be used to produce higher quality spaces, that meets the needs and manages to express the culture of those who inhabit them. The study, different from traditional methods and alternative construction should favor the development of a new stage in the construction of each country, which makes it possible to incorporate and adapt new technologies which improve the quality of life of the inhabitants thanks to housing problems solutions. In this sense, living spaces for men a system presents the possibility of renewing the prefabrication of multiple spaces such as houses, schools, wellness center for spatial flexibility. It is ideal for the industrialization of prefabricated elements system and to display a regularity and the repetition of elements which makes it easier to produce and therefore creates spaces which gives it a better quality of life. I want to thank Carlos Ancheta, CIEF professor for this original idea.

Fiberglass molds.




The fiber is cut in a hand gun and introduced into a catalyzed resin spray directed towards the mold. The deposited materials are left to harden under standard atmospheric conditions.

Explanation of

Material options

Resins: mainly polyester.
Fibers: glass wicks only.
Cores: No. These must be incorporated separately.

Main advantages

1) Widely used for many years.
2) Inexpensive way to quickly deposit fibers and resin.
3) Low cost tools.

Main disadvantages

1) Laminates tend to be very rich in resin and therefore excessively heavy.
2) Only short fibers are incorporated, which considerably limits the mechanical properties of the laminate.
3) Resins must have a low viscosity before they can be sprayed. This generally compromises their mechanical properties / thermal.
4) The high styrene contents of aerosol resins generally mean that they have the potential to be more harmful and that their lower viscosity means that they are more likely to penetrate clothing., etc.
5) Limiting airborne styrene concentrations to legal levels is becoming increasingly difficult.

Typical applications

Single speakers, lightly loaded structural panels, for example caravan body, truck fairings, bathtubs, shower trays, some small canoes.

  1. Greetings!

    I am an old Friend of Jorge Castillo from his London days, do you happen to have a contact for him? Or would you very kindly pass my email on to him and ask him to get in touch if he would like to. Many thanks,
